Texas (Austin and Waco). 



"With the t3pical forms of this species, I have placed numerous 

 aberrant or varietal forms from New Mexico, Iowa and Montana; 

 some of them are lai-ger and stouter with longer puljescence ; 

 others have a large piceous cloud on the ehtra. There certainly 

 seem to be some closely allied but distinct species involved, which 

 can onl^^ be successfull3' studied with larger series from numerous 

 localities. 



53. A. agilis n. sp. — Motierately uarrow and convex, polished, Llack 

 throughout, the legs dark piceo-rufous; antennae jmler rufo-testaceous; pubes- 

 cence long, coarse, cinereous, somewhat dense and very conspicuous, subde- 

 cumbent. Head subquadrate, as long as wide, broadly, very feebly arcuato- 

 truncate, the angles moderately rounded; ejes somewhat small, not very 

 convex, much shorter than the tempora; disk strongly and very closely punc- 

 tate, the narrow impimctate line almost obliterated toward base; antennae 

 only one-half longer than the head, quite distinctly iiierassate, the tenth joint 

 slightly transverse. Prothorax rather large, sube<iual in Avidth to the head, 

 very nearly as long as wide, narrowly rounded at apical fourth or fifth, the 

 sides obliijue and straight thence to a very feeble and obtuse subbasal con- 

 striction; apex transversely truncate, rounded laterally; disk strongly and 

 very densely punctate. Elytra elongate, fully three-fourths longer than wide, 

 twice as wide as the prothorax, moderately obtuse at apex; sides parallel and 

 feebly arcuate; humeri broadly rounded to the prothorax ; scutellar impression 

 and omoplates obsolete; punctures rather small Init deep, Avell separated. 

 Abdomen polished, finely and closely but distinctly punctured throughout, the 

 legs somewhat long and slender. Length 2.4 mm. ; Avidth 0.8 mm. 



Wyoming (Green River). Mr. Wickham. 



Allied somewhat closel}^ to herifuga^ but differing in its larger 

 size, more elongate elytra, wider prothorax which is more nar- 

 rowl}^ rounded at a point much nearer the apex, more transversely 

 truncate head and several other features. 



54. A. Iierifuga n. sp. — Not stout, somewhat depressed, polished, black, 

 the prothorax slightly paler, especially toward Ijase; legs and antenntc pale 

 piceo-testaceous ; pubescence long, subdecumbent, cinereous, coarse, rather 

 abundant and very conspicuous. Head somewhat small, subquadrate, fully as 

 long as w ide, the base broadly and distinctly arcuate, the angles obvious but 

 broadly rounded ; eyes rather small and not very prominent, much shorter 

 than the tempora, the latter parallel behind them for some distance, gradually 

 citrving into the base; disk strongly, verj^ closely punctate; antennae almost 

 as long as the head and prothorax, the outer four joints distinctly though 

 gradually enlarged, the tenth slightly transverse. Prothorax small, distinctly 

 narrower than the head, not as long as wide, rather broadly rounded at apical 

 fourth, the sides thence oblique and straight to the basal margin which is
