coarsely but closely-, deepi}' and very distinctly punctate. Abdo- 

 men minutely, ver^- denseh' punctulate and pubescent, more 

 sparsely so toward the middle and base. Legs short, the femora 

 rather thick. Length l.I) mm.; width 0.55 mm. 



Colorado (Garland.) This very small species ma}- be distin- 

 guished at once from the two which precede, not only by the 

 characters given in tlie table, but b}- the more abrupt and notice- 

 ably enlarged five outer joints of the antenufe. In formicetoruni 

 these joints form a true, though feeble, five-jointed club, while in 

 deser/orum the transition from the sixth to eighth joints is so 

 gradual in width, that there is scarcely the suspicion of a club. 



10. V. Slispectll§ n. sp. — ilotlerately stout and convex, feebly shining, 

 pale brownisli-testaceons, the suture and apex of the elytra clouded witli 

 blackish ; pubescence close and conspicuous, much longer on the elytra. Head 

 quadrate, convex, rather coarsely and somewhat closely punctate, the inter- 

 spaces smooth and even: eyes small, miich shorter than the tempora, the latter 

 parallel for a long distance behind them, thence rather narrowly rounded into 

 the broadly arcuato-truncate base ; antennic missing in the type. Prothorax 

 large, about as long as wide and very distinctly Avider than the head, the out- 

 line nearly as in the three preceding species; surface convex, tinely and 

 densely punctate. Eh/fra large, two-thirds longer than wide, not quite twice 

 as wide as the jirothorax, perceptibly dilated behind the middle, broadly, 

 obtusely rounded at apex, the humeri widely exposed at base; disk strongly 

 aud conspicuously impressed at the scutellum, closely strongly and rather 

 coarsely punctate. Abdomen somewhat closely pubescent, the punctxires very 

 minute, /.ri/x short and rather slender. Length 2.3 mm. ; width 0.7 mm.

The unique tj'pe is a female from the Levette cabinet, and is in 

 all probabilit}' from the localit}" stated above. It represents a 

 much larger and stouter species thviw for micetorum, with smaller 

 eyes and more parallel tempora, besides the other characters here- 

 tofore mentioned. 



HEIWAXTUS n. gen. 



The general habitus of Anthicus Jioralis is peculiar and aber- 

 rant in its smooth subglabrous surface, in the occurrence of a 

 subapical modification of the pronotum — always a significant 

 structure in this famil}', — in its stout antenna?, robust legs 

 with quite distinctly clavate femora, and other features, so that 

 its systematic position among the other species has always been 

 uncertain. When we add to these disparities of structure the
