_Records of occurrence._--Specimens examined, 17: Miquihuana, 6200 ft., 2; 14 mi. N, 6 mi. W Palmillas, 5500 ft., 1; Nicolas, 56 km. NW Tula, 5500 ft., 1; Sierra de Tamaulipas, 2 mi. S, 10 mi. W Piedra, 1200 ft., 12; Joya Verde, 35 km. SW [Cd.] Victoria, 3800 ft., 1.

Additional record: Aserradero del Paraiso (Goodwin, 1954:186).

=Lasiurus borealis=

Red Bat

Two subspecies of _Lasiurus borealis_ have been reported from Tamaulipas. One, _L. b. borealis_, is known only from Matamoros, whereas the other, _L. b. teliotis_, is widely distributed in the central and southern parts.

A young animal from Ciudad Victoria was captured inside a house. All specimens taken in the Sierra de Tamaulipas were caught in mist nets, in which _Centurio senex_, _Pteronotus parnelli_, and _Mormoops megalophyla_ also were taken.

=Lasiurus borealis borealis= (Muller)

1776. _Vespertilio borealis_ Muller, Des Ritters Carl von Linne ... vollstandiges Natursystem ..., Suppl., p. 20, type from New York.

1897. _Lasiurus borealis_, Miller, N. Amer. Fauna, 13:105, October 16.

_Distribution in Tamaulipas._--Known only by two specimens from Matamoros (Miller, 1897:108).

=Lasiurus borealis teliotis= (H. Allen)

1891. _Atalapha teliotis_ H. Allen, Proc. Amer. Philos.

Soc., 29:5, April 10, type from an unknown locality, probably some part of California.

1897. _Lasiurus borealis teliotis_, Miller, N. Amer. Fauna, 13:110, October 16.

_Distribution in Tamaulipas._--Generally distributed in higher parts of state.

Eight June-taken females, all lactating, from the Sierra de Tamaulipas averaged 10.0 (8-12) grams; five males from there weighed 9.2 (8-10) grams. According to Hall and Kelson (1959:188), males of this species usually are more brightly colored than females but this phenomenon is not evident in the Tamaulipan specimens. Males do, however, average slightly smaller than females.

The name _Lasiurus borealis teliotis_ is employed following Handley (1960:472); formerly _L. b. ornatus_ Hall was applied (Hall and Kelson, 1959:190) to bats here referred to as _teliotis_.

_Records of occurrence._--Specimens examined, 7: Cd.

Victoria, 1800 ft., 1; Sierra de Tamaulipas, 2 mi. S, 10 mi.

W Piedra, 1200 ft., 1; Sierra de Tamaulipas, 3 mi. S, 14 mi.

W Piedra, 1200 ft., 1; Sierra de Tamaulipas, 3 mi. S, 16 mi.

W Piedra, 1400 ft., 4.

=Lasiurus cinereus cinereus= (Palisot de Beauvois)

h.o.a.ry Bat

1776. _Vespertilio cinereus_ (misspelled _linereus_) Palisot de Beauvois, Catalogue raisonne du museum de Mr. C. W.

Peale, Philadelphia, p. 18, type from Philadelphia, Pennsylvania.

1864. _Lasiurus cinereus_ H. Allen, Smiths. Misc. Coll., 7 (publ. 165): 21, June.

_Distribution in Tamaulipas._--Probably state-wide but so far reported only from Matamoros (Miller, 1897:114), and Aserradero del Infernillo (Goodwin, 1954:6--cranium only).

=Lasiurus intermedius intermedius= H. Allen

Northern Yellow Bat

1862. _Lasiurus intermedius_ H. Allen, Proc. Acad. Nat. Sci.

Philadelphia, 14:246, "April" (between May 27 and August 1), type from Matamoros, Tamaulipas.

_Distribution in Tamaulipas._--Eastern half of state, known only from three localities.

The three specimens examined were taken in mist nets along with _Lasiurus ega_, _Pteronotus rubiginosus_ and _Mormoops megalophylla_.

The generic name _Lasiurus_ is used instead of _Dasypterus_ following Hall and Jones (1961).

_Records of occurrence._--Specimens examined, 3: Sierra de Tamaulipas, 2 mi. S, 10 mi. W Piedra, 1200 ft., 1; Sierra de Tamaulipas, 3 mi. S, 16 mi. W Piedra, 1400 ft., 2.

Additional record: Matamoros (H. Allen, 1862:246).

=Lasiurus ega xanthinus= (Thomas)

Southern Yellow Bat

1897. _Dasypterus ega xanthinus_ Thomas, Ann. Mag. Nat.

Hist., ser. 6, 20:544, December, type from Sierra Laguna, Baja California.

1953. _Lasiurus ega xanthinus_, Dalquest, Louisiana State Univ. Studies, Biol. Ser., 1:61, December 28.

_Distribution in Tamaulipas._--Probably occurs in southern and western parts of state; certainly known only from the Sierra de Tamaulipas.

Three June-taken females, all captured in mist nets, were lactating.

Hall and Jones (1961:91) a.s.signed all Mexican specimens of the southern yellow bat to _Lasiurus ega xanthinus_, but remarked that specimens from western Mexico were paler than those from the east. Of the six specimens examined from Tamaulipas, four are dark, resembling in color specimens from Veracruz, Yucatan and Costa Rica, and the other two are somewhat paler, approaching specimens from Baja California, Zacatecas and Coahuila. In measurements, Tamaulipan specimens of _Lasiurus ega_ generally resemble specimens from the west, but differ from any other _L. ega_ seen in having a longer tail, longer ear, and shorter maxillary tooth-row.

_Records of occurrence._--Specimens examined, 6: Sierra de Tamaulipas, 10 mi. W, 2 mi. S Piedra, 1200 ft., 4; 10 mi. W, 3 mi. S. Piedra, 1200 ft., 1; 16 mi. W, 3 mi. S. Piedra, 1400 ft., 1.

=Nycticeius humeralis=

Evening Bat

_Nycticeius humeralis_ has the same distributional pattern in Tamaulipas as has _Lasiurus borealis_ in that both are represented there by two subspecies, one known only from Matamoros and the other occurring in the rest of the state. Bats of this species (_N. h.

mexica.n.u.s_) from Ciudad Victoria and some from the Sierra de Tamaulipas were shot in flight in evening; others from the last-mentioned locality were taken in mist nets. Lactating females (22 specimens) were collected in June and July.
