FALL AND COCKKRELL. 235 



claws narrowly cleft, the inner portions widely distant, the present 

 species would'hy Horn's table fall near politus, which aside from 

 the form of the claws differs in numerous other detads. 



LAMPYRID^. 



Teiephorns insipidus n. sp.-Slender, parallel, dusky testaceous 

 throughout, finely pale pubescent. Antenna slender, filiform, a h tie shorter 

 than the entire length of the insect, joints one and three subequal in leiigth, two 

 barely half as long as three, four to eleven longer and nearly equal. Head shin- 

 ing very finely not closely punctate, front about one-half wider than the vertical 

 diameter of the eye. Prothorax slightly longer than wide, parallel, hind angles 

 obtuse but well defined, front angles wanting; disk feebly channeled along the 

 median line, sides rather deeply broadly impressed anteriorly, tumid each side 

 posteriorly, hind margin narrowly reflexed ; surface shining and virtually im- 

 punctate." Elytra about one-half wider than the prothorax, finely scabix,us, 

 elevated lines "very fine and indistinct. Claws simple on all the feet, the base 

 merely a little thickened. Length 9.5 mm. ; width 2 mm. 

 Cloudcroft, Sacramento Mts. (Knaus). 



A single male specimen kindly given me by Mr. Knaus. This 

 species differs from viarginellus, the only previously described species 

 having simple claws, in size, color and relative dimensions of the 

 prothorax. Quite likely there are other differences which the short 

 description of LeConte does not enable me to indicate. 



Polemiu!^ rejjularis n. sp.— Black, sides of front beneath the antennal 

 cavities narrowly pale; sides of prothorax broadly pale, the dorsal black stripe 

 entire of uniform width and slightly narrower than the pale margins. Pro- 

 thorax transverse, sides parallel and broadly arcuate, hind angles somewhat 

 obtuse and not sharply defined, their vertices a little rounded ; front angles 

 wanting. Elytra scabrous, with the raised lines feeble but traceable, more dis- 

 tinct toward the base. Length 8.5 mm. ; width 3.5 mm. 

 Albuquerque (Wick ham ). 



Described from a single female specimen. A second female taken 

 by Knaus at Fresnal Canon is slightly different, but is associated 

 with the type for the present. 



Regularis is rather closely allied to two or three of the described 

 species, but on comparison with the LeConte types it looks sufficiently 

 distinct, though it must be confessed that specimens of several of 

 the described" species are too few to permit one to judge as to the 

 extent of specific variability. As compared with the present species 

 princeps differs in its larger size, pale front, incomplete pronotal 

 vitta and margined elytra ; stremms has the pronotal vitta strongly 

 dilated before the base, and marginicollis has the prothorax trape-
