Texas (Austin and Waco). 



With the typical forms of this species, I have placed numerous 

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

 some of them are larger and stouter with longer pubescence ; 

 others have a large piceous cloud on the eh tra. There certainly 

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

 can only be successfully studied with larger series from numerous 

 localities, 



53. A. agilis n. sp. — IModerately nariow and convex, polished, black 

 throughout, the lefi;s dark piceo-rufous; antennie paler ruf o-testaceous ; puhes- 

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

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

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

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

 tate, the narro^\- impunctate line almost obliterated toward base; antenna; 

 only one-half longer than the bead, (juite distinctly incrassate, the tenth joint 

 slightly transverse. Pmthorax rather large, sube(|ual in width to the head, 

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

 sides obli(iue and straight thence to a very feeble and obtuse subbasal con^ 

 striction; apex transversely truncate, rounded laterally; disk stronglj' 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 but deep, well sepai'ated. 

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

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



Wyoming (Green River). Mr. Wickham. 



Allied somewhat closely to herifuga, but differing in its larger 

 size, more elongate el^'tra, wider prothorax which is more nar- 

 rowly rounded at a point much nearer the apex, more transverse^ 

 truncate head and several other features. 



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

 the prothorax slightly i)aler, especially toward ])ase; legs and antenna; pale 

 piceo-testaceous ; pubescence long, su1)decumbent, cinereous, coarse, rather 

 abundant aiul very conspicuous. Head somewhat small, siilxiuadrate, fully as 

 long as wide, 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 

 curving into the base; disk stronglj', very closely punctate; antennie almost 

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

 gradually enlarged, the tenth slightly transverse. I'roihorax small, distinctly 

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

 fourth, the sides thence obli<]ue and straight to the basjil margin which is
