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

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

 characters given in the table, but bj' the more abrupt and notice- 

 ably enlarged five outer joints of the antennae. In formicetorum 

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

 desertorum the transition from the sixth to eighth joints is so 

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



10. y. suspectiis n. sp. — Moderately stout and convex, feebly shining, 

 pale brownish-testaceous, the suture and apex of the elytra clouded with 

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

 ((uadrate, convex, rather coarsely and somewhat closely punctate, the inter- 

 spaces smooth and even; eyes small, much shorter than the tempora, the latter 

 liarallel for a long distance behind them, thence rather nanowly rounded into 

 the broadly arcuato-truncate base; antenuic missing in the type. Prothorux 

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

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

 densely pimctate. Elytra large, two-thirds longer than wide, not quite twice 

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

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

 and conspicuously impressed at the scutellum, closely strongly and rather 

 coarsely punctate. AMouwn somewhat closely pubescent, the punctures very 

 minute, /.(//.s short and rather slender. Length 2.3 mm.; width 0.7 mm.

The unique t^pe is a female from the Levette cabinet, and is in 

 nil probability from the locality stated above. It represents a 

 much larger and stouter species than /brmiceforwm, with smaller 

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

 tofore mentioned. 



HEMAiXTUS n. gen. 



The general habitus of Anthicus Jloralis 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 family, — in its stout antennae, robust legs 

 with (luite 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
