PTEROSTICHUS PUMPELLVI sp. nov. 

 PI. III. fig. 3. 



This species may be best compared to our existing- P. comcinus Newm. 

 It is a large species with a smooth head and thorax, the former with a dis- 

 tinctly impressed straight transverse line connecting the anterior bases of 

 the antenna, and the eyes large but not greatly prominent. The thorax is 

 somewhat crushed and distorted, but it is apparently broader than long, 

 with gently rounded sides, the front angles square but not projecting, and 

 the posterior margin squarely truncate. The elytra have a slight, well- 

 rounded humeral angle, the stria3 are deep and simple, and the interstitial 

 spaces strongly convex; the sutural stria, not shown in the drawing, is of 

 moderate length and does not appear to unite with the first regular stria in 

 the figured specimen, but does so plainly in the other. One specimen 

 shows the whole upper surface of the body excepting the two front pairs 

 of legs, part of one elytron, and the abdomen; the other a single elytron. 



Length of body, 1G.5 mm.; of elytra, 9.75 mm.; breadth of one of latter, 

 3.5 mm. 



Florissant, Colorado; two specimens, Nos. 401, 517. 



Named for Raphael Pumpelly, United States geologist.
