 5.6-9.0 mm. ; width 2.0-3.3 mm. 



New Mexico (Fort Wingate). Dr. Shufeldt. 



The description is taken from the male ; the female does not 

 differ greatly but is larger, the antennae slightly longer than the 

 head and prothorax, joints eight to ten decreasing rapidly in length, 

 the latter but slightly longer than wide, the elytra a little more 

 inflated and from one-third to one-half wider than the prothorax. 



This species is allied to attenuata Lee, but differs in its shorter, 

 more transverse prothorax, with less strongly arcuate apex, and in 

 the much more impressed and coarsely punctate elytral striae. It 

 varies greatly in size, but the prothorax is equally transverse 

 throughout the seven specimens which 1 have before me. The 

 epipleuroe are narrow throughout as usual.

The high regions of New Mexico and southern Colorado con- 

 stitute a peculiar faunistic region or province, containing a large 

 proportion of strictly endemic species ; in support of this statement 

 scores of examples might easily be cited. The genera to which 

 these species are referrable are generally widely distributed, but in 

 several instances which may or may not be indicative of. a more 

 general tendency, the genus — as in Thyce — reappears only in the 

 true Pacific coast fauna, without inhabiting the intervening dis- 

 tricts as far as known. 



For a long time past we have had specimens in our cabinets, 

 belonging to the present genus, from New Mexico, and others from 

 northern California to British Columbia, but none whatever from 

 the intermediate regions ; this fact alone should have led us to 

 examine these specimens somewhat critically. It may be stated as 

 the result of such an examination that the well-known rule above 

 mentioned is thoroughly supported in this case, for it is perfectly 

 evident that the New Mexican form is specifically distinct from the 

 California representatives called sjriculatus by LeConte, and subse-
