in the male, evidently more than that in the female. Joint three of the antennae 

 barely as long as two and nearly equal to four and five together, the latter two 

 mutually equal; sixth to eighth suhequal and scarcely as wide as long in the 

 female, strongly transverse in the male ; ninth nearly as long as all the preceding 

 united in the male, and rather longer than the five preceding in the female. 

 Prothorax less than twice as wide as long, narrowed in front, sides moderately 

 rounded and somewhat explanate, hind angles wanting. Prosteruum before the 

 coxae about as long as half the thickness of the coxa from front to back. Meta- 

 sternum rather closely scabrous punctate. Length 2.5-4 mm.

19. E. teiiiii<*oriiiS Lee— Very similar to luteipennis, differing chiefly in 

 its uniformly rufotestaeeous color in both sexes, and in the narrower and longer 

 three outer antenna! joints, these being scarcely wider than the preceding joints 

 (about twice as wide in luteipennis) and each suhequal in length to all of them com- 

 bined. The prothorax is rather more coarsely granulate than in luteipennis and 

 the last palpal joint is a little more dilated externally. Length 3.5 mm. 



The type of this species was taken at York, Pennsylvania; the 

 few specimens before me are from Massachusetts (collections of 

 Blanchard and Bowditch), where it occurs, but uncommonly on 

 Pinus rigidus. 



20. E. marginicollis Lee— Moderately elongate, dark brown, punctua- 

 tion simple or very nearly so throughout, rather close on the head and prothorax, 

 sparser on the elytra; pubescence cinereous, unusually long and abundant with 

 intermixed erect hairs. Eyes rather small but strongly convex, the front a little 

 wider than twice their vertical diameter in the male and still wider in the 

 female; front quite deeply transversely impressed along the epistomal suture. 

 Terminal joint of palpi widest at or behind the middle and narrowing apically. 

 Third joint of antennae slightly longer than the second or fourth ; sixth to eighth 

 short, ninth as long as the five preceding in the male, a little longer than the 

 three preceding in the female. Prothorax scarcely as wide as the elytra, less than 

 twice as wide as long, sides nearly parallel or slightly convergent anteriorly, 

 broadly rounded, margin rather wide, distinctly reflexed and serrulate along the 

 edge; hind angles nearly as well defined as the front ones. Prosternum longer 

 than usual before the coxae, being evidently more than half the coxal diameter 

 from front to back. Metasternum sparsely punctured posteriorly, more closely 

 in front. Legs strongly narrowed or pedunculate at base. Length 2.25-5.2 mm. 



Oregon, Vancouver, California. 



The type is a male said to be from the first named locality, and 

 with it in the LeConte collection is a female from Vancouver. All 

 the specimens at hand are from the Middle California coast region, 

 San Francisco, Alameda, Santa Clara and San Mateo Counties. A 

 number of specimens in the series before me differ slightly from what
