member of the Eurygeniini, especially in the structure of the an- 

 tenna? and palpi and basal parts of the head. 



yi, loiigicoriiis n. sp. — Narrow, convex, polished, black, the elytra, 

 mandihles except at tip, and the base of the first hind tai-sal joint rnfo-testa- 

 ceons; vestiture rather sparse, coarse, not at all concealing the surface sculpture 

 and only slightly and indefinitely irregular on the elytra, yellowish -cinereous 

 in color. Head as long as wide, suboval, rather convex, somewhat coarsely, 

 not densely punctate; basal constriction feeble, slightly arcuate; neck very long 

 dorsally, fully two-thirds as wide as the head; eyes separated by about twice 

 their own width; tenipora convergent behind them and about three-fifths as 

 long; mandibles prominent; anteuuie nearly as long as the body, opaque black 

 and, excepting the two basal joints, clothed with short dense stiflf pubescence 

 throughout, two basal joints shining, sparsely setose. Prot/iorax rather wider 

 than the head, fully as long as wide, the sides feebly convergent and broadly arc- 

 uate from the middle to the strong apical constriction, rather abruptly nar- 

 rowed at the middle, the sides thence feebly oblique and sinuate to the base; 

 disk convex, not coarsely, feebly, unevenly and sparsely punctate, the canalicu- 

 latiou fine but distinct, broadly, feebly impressed. Elytra three-fourths wider 

 than the prothorax, slightly more than twice as long as wide, the sides par- 

 allel and straight, obtusely rounded in apica.1 fifth; humeri transversely 

 rounded to the prothorax ; punctures very coarse, deep, the interspaces about 

 as wide as the punctures, not punctulate. AJxlomen feebly and sparsely punc- 

 tate, coarsely and sparsely pubescent. Length 6.0 mm.; width 1.6 mm. 



Arizona (Pinal Mts.), Mr, H. F. Wickham. 



The unique type is a male, having very feeble abdominal 

 characters, the copulatory spicule sagittiform as in Retocomus 

 and other genera of the tribe. This form is absolutely ditferent 

 from that seen in Pedilus and Macratria. 



STEREOPALPITS Laf. 



This well known genus is somewhat rich in species, occurring 

 throughout the United States ; I have separated the eleven known 

 to me as follows : — 



Vestiture uniform in distribution and in general tint. 

 Head equal in width to the prothorax. 



.Species of the Atlantic regions ; pronotal sculpture finer and less dense, 

 the elytral punctiu'es coarser and more distinct. 

 Elytra generally concolorous, though often a little paler; median strii- 

 form sulcus of the pronotum usually distinct at least near the base. 



iiiellyi Laf. 



Elytra always paler, rufous; irrteguments thicker, the i)ronotaI stria 



generally subobsolete, though occasionally (juite readily traceable
