PIPISTRELLUS SUBFLAVUS OBSCURUS subsp. uov. 



Type from Lake George, Warren County, N. Y. Adult 9 (skin) No. 67723, U.S. 

 National Museum (Biological Survey collection). Collected September 6, 1894, by 

 Walter K. Fisher. Original number, 198. 



General characters. — Size and proportioDS as in typical subflavus, but 

 color duller and less yellow, and dark tips of sliorter hairs on back 

 more conspicuous. 



JEars, mc)}ibrane8, fcet^ and fur. — As in typical suhflavus. 



Color. — Fur everywhere blackish slate at base. Middle band on 

 shorter hairs of back dull, pale, wood brown or Isabella color. Tips of 

 these hairs dusky brown, and much more conspicuous than in true sub- 

 flavus. Long hairs of back pale wood brown. Belly uniform Isabella 

 color, in some specimens inclining toward wood brown, but seldom show- 

 ing any apj) roach to the bright yellowish brown of true siibflavus. 



A melanistic specimen is dark chocolate brown throughout. Two 

 others are rich reddish brown. In all three of these abnormal individ- 

 uals tlie characteristic variegation of the fur of the back still persists. 



Slcull and teeth. — I can find no cranial or dental characters to distin- 

 guish Pqmtrelhis subflavus obscures from the typical subspecies. 



Measurements. — See table, page 95. 



Speciiymis examined. — Thirty four (seven skins), all from the type 

 locality. 



General remarks, — Pipistrellus subflavus obscurus is readily distin- 

 guishable from true subflavus by its darker, duller, less yellow color. 

 The difference is especially noticeable on the ventral surface, which is 

 generally a rich yellowish wood brown in tjineal subflavus, dull Isabella 

 color in obscurus. The darker hue of the back in obscurus is due partly 

 to differences in the color of the long hairs, and of the middle bands 

 of the short bairs, and partly to the more extended dark tips of the 

 short hairs. Like the typical form, Fixristrcllus subflavus obscurus 

 varies considerably in color, so that individual specimens of either sub- 

 siDecies, especially those that are not fully adult, are sometimes difficult 

 to identify. When series are compared, however, the differential char- 

 acters at once become apparent.

Type locality. — Las Yegas, Jalapa, Yera Cruz. 



Geographic distribution. — This species is known from the type locality 

 only. 



Characters. — As I have seen no specimens of Fipistrellus verwcrucis, 

 I co-py the original description. 



All six specimens Avere indistinguishable one from another in point of color. The 

 following color-description is taken I'rom a dried skin, whereas all the rest of the 

 description is taken from a specimen preserved in alcohol.
