the Cornell University collection. This small pale species 

 bears a close resemblance to Leioscyta ferruginipennis var. 

 tcstacea V. D. and I formerly considered it the female of that 

 species but recently I have examined a series of both sexes of 

 the Leioscyta and believe this to be quite distinct. I am led to 

 place it in Enchenopa by the presence of at least rudiments of 

 two intermediate carinse on the anterior base of the dorsal pro- 

 cess. The elytral venation in these two genera agree entirely 

 and in the form of the pronotal horn the present species is 

 strictly intermediate. The name here used is one given it in 

 MS by Dr. Uhler. 



Genus Leioscyta Fowler. 



Leioscyta ferruginipennis Goding. 



I have seen no specimen that exactly agrees in color with 

 the dark form described by Dr. Goding from California but at 

 Grand Junction, Colorado, I took a maculated individual that 

 is intermediate between that and the pale variety described 

 below as variety tcstacea with which it seems to be specifically 

 identical. The pronotum is of the same pale yellowish testa- 

 ceous varied here however with fuscous. These marks form 

 an indistinct transverse band behind the middle, an irregular 

 mark along the lateral carinae and a spot on the superior angle. 

 The lower surface is blackish, the tibiae are banded and the 

 elytra are fuscous, becoming testaceous at base and whitish on 

 the clavus and at apex. 



Leioscyta ferruginipennis var. testacea n. var. PI. 2, fig. 33. 



Pale testaceous yellow with the tip and a slender mark on 

 the dorsal carina anterior to this brown or blackish in some ex- 

 amples. Elytra testaceous varied with whitish at apex and 

 across the middle. Pectus and abdomen tinged with ferru- 

 ginous. Tibiae faintly banded in some examples. 



I believe this to be specifically identical with the dark form 

 described by Dr. Goding but the examination of more extensive 

 material may necessitate raising it to specific rank. This pale 

 form was taken by Prof. Ball and myself at Rifle and Grand 

 Junction, Colorado, Prof. Wickham has sent me specimens from 

 St. George, Utah, and the Cornell University collection has one 

 specimen from Arizona.
