across the eyes ; antennae rather slender, as long as the head and 

 prothorax, feebly incrassate distally ; prothorax barely as long as wide, a 

 little wider than the head, broadly, evenly convex, with distinct basal 

 margin, the sides denticularly and conspicuously prominent at apical fifth 

 or sixth, thence converging and nearly straight to the base; elytra parallel, 

 the sides feebly arcuate ; apex obtusely subtruncate, the humeral angles 

 well rounded, not quite twice as long as wide, about three-fourths wider 

 than the prothorax, and three times as long ; surface almost evenly 

 convex, feebly flattened toward the suture, the subbasal tumidity wholly 

 obsolete. Length 3.0 mm ; width, 0.9 mm. 



Colorado (Colorado Springs). Mr. H. F, Wickham. 



This remarkable species will form an exception in the particular 

 arrangement of species proposed by the writer for our representatives of 

 Anthicus (Ann. N. Y. Acad. Sci., VIII., p. 6S7), in that, being one of the 

 larger species, it must be placed, because of its general structure and 

 affinities, near the very small convexiilus at the end of the table. The 

 head is finely, very closely punctured, with a narrow entire impunctate 

 line, expanding anteriorly, where it seems to be slightly tumid. 



DiNOCLEUS, Csy. 



D. pojxatus, n. sp. — Small in size and rather narrowly suboblong- 

 oval, deep black, partially clothed with narrow pointed decumbent white 

 scales, a broad pronotal area but little more than half as wide in front as 

 at base, subdenuded, the elytra very coarsely furrowed, the furrows coarsely 

 and deeply but not closely punctured, the first and second deeper and 

 more coarsely punctured from near the base to apical third, the third and 

 fourth generally from basal fifth to near the middle, these more 

 coarsely punctured parts subdenuded of vestiture, the fifth and sixth also 

 more denuded, especially behind the middle ; prothorax very strongly 

 dentate and prominent laterally at apical fourth, the sides converging and 

 more or less sinuate thence to the base ; disk very coarsely and closely 

 punctate ; beak more or less prominent along the median line. Length 

 from the eyes to the elytral apex, 7.0-8.5 mm.; width, 2.75-3.25 mm 



Utah (Ogden). Mr. Hugo Soltau. 



Allied to deniicoliis, but smaller and narrower, and with the vestiture 

 sparser, the elytra more coarsely and deeply furrowed, and more coarsely 

 punctate, the elytral intervals alternately more prominent and convex, but 

 only conspicuously so along the more coarsely punctate and denuded 

 parts. The lateral prominences of the prothorax are even more 

 developed than in denticoUis,
