(Continued from p. 69, vol. vi.) 



PACHYTA Serville. 

 Prothorax acutely armed at the sides; eyes moderate, feebly 

 emarginate ; tibial spurs terminal as usual. The species may be 

 separated as follows : 



Elytra slightly tapered, maculate, nearly rounded at tip . . . montlcola. 

 Elytra strongly narrowed behind, testaceous, maculate or black, feebly trun- 

 cate and dehiscent liturata. 



Elytra strongly narrowed behind, truncate and subbidentate at tip, posterity- 

 half of side margin black, reaching suture at tip . . . . armata. 

 Elytra subparallel, subaeneous with narrow transverse band wavy, tip 



rounded rugipennis. 



Elytra subparallel, testaceous, truncate at tip spnrca.

Anticosti. 



Black, elytra finely and densely pubescent, testaceous with tip 



and four black spots, nearly confluent along a line near the suture.

 Black, elytra coarsely and confluently punctured, glabrous, hu- 

 meri prominent, testaceous, vaguely or decidedly quadrimaculate 

 with black or entirely black. Antennae short and very stout 9 , or 

 about half the length of body and more slender S . 

 P. armata Lee, S. M. C, No. 264, 1873, p. 207. 



Length 16—19 mm. = .64— .76 in. Hab.—\N. T., Or., Id. 



Black, elytra punctured as in preceding, humeri prominent and 

 disc very convex behind the base, testaceous with black space ex- 

 tending from suture at tip oblicjuely to the middle of the margin. 

 Antennae, 9 , half as long; $ , nearly as long as body. 

 P. ragipennis Lee. 1. c. (Newn. ms.). 



Length 13— 16 mm. = .51— .64 in. Hab.— Can. 



Black, subaeneous, antennae, femora and base of tibiae ferrugi- 

 nous. The sculpture of the elytra consists of a reticulation of smooth, 

 strongly elevated lines with the depressed spaces coarsely punctured ; 

 from the punctures proceed rather coarse golden hairs. Antennae: 

 % , two-thirds as long as body: 9 , shorter.
