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

 teniipe and palpi and basal parts of the head. 



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

 maudibles except at tip, and the base of the first hind tarsal joint riifo-testa- 

 ceous ; vestitnre 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; tempora convergent behind them and about three-fifths as- 

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

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

 throughout, two basal joints shining, sparsely setose. Prothorax rather Avider 

 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- 

 lation 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 apical fifth; humeri transversely 

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

 as wide as the punctures, not punctulate. Ahdomcn 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 t^'pe is a male, having ver^^ feeble abdominal 

 characters, the copulator\' spicule sagittiform as in Retocomus 

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

 from that seen in Pedilus and Macratria. 



STEREOPALPl S 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 ; pronota.1 sculpture finer and less dense, 

 the elytral punctures coarser and more distinct. 

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

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



iiiellyi Laf. 



Elytra always paler, rufous: integuments thicker, the pronotal stria 



generally subobsolete, though occasionally quite readily traceable
