34. A. Ktellatiis n. sp. — Somewhat stout and convex, shining, black, the 

 legs and autennaj dark rufous, with the femora darker, each elytron with a 

 large pale spot in basal fifth and another smaller and rounded at apical fourth ; 

 pubesence short, coarse, semi-erect, even, cinereous and rather dense, the hairs 

 of the head and, to some extent, of the pronotum arcuate and thickened at 

 apex. Head large, quadrate, convex, truncate and strongly, medially im- 

 pressed at base; angles rounded; tempora parallel, longer than tlie eyes, the 

 latter moderately developed and prominent; surface strongly, closely punctate, 

 the smooth medial line ill-defined toward base; antennae rather slender, nearly 

 as long as the head and prothorax, moderately incrassate, the tenth joint 

 somewhat wider than long. Prothorax scarcely more than three-fourths as 

 wide as the head, not longer than wide, broadly rounded at the sides an- 

 teriorly, sinuate at basal fourth, convex, fineh' but strongly, densely i)unc- 

 tate. Elytra large, two-thirds longer than wide, much more than twice as 

 wide as the prothorax, distinctly wider at a little behind the middle than at 

 base, broadly rounded behind, gradually dehiscent in apical fifth or sixth; 

 humeri moderately exposed; scutellar impression rather narrow and distinct ; 

 omoplates snbobsolete; punctures deep but not verj' large, separated by about 

 their own widths. Abdomen dull, minutely, closely punctate, also minutely 

 reticulate. Legs somewhat long and slender. Length 3.2 mm. ; width 1.1 mm. 



Wyoming (Laramie). 



The onl}' species to be compared with this is the Californiau 

 auriger, which differs in its much less obese form and in its 

 smaller head, in addition to coloration. 



35. A. aitriger n. sp. — Not stout, rather convex, shining, black through- 

 out, the femoi'a black; tibiic and tarsi abruptly pale flavate; antenna^ dark 

 ruf o-testaceous ; each elytron with two rounded flavate spots, one slightly 

 larger at basal fifth, the other at apical fourth; pubescence short, semi-erect, 

 cinereous, moderately close, the hairs of the head and pronotum clavate and 

 recurved, those of the elytra simple. Head quadrate, fully as long as Avide, 

 convex, trunciite and medially impressed at base; angles distinct but broadly 

 rounded; temi)ora long, feeldy convergent behind the eyes, the latter moder- 

 ately developed and prominent; punctures strong but not very large and rather 

 close-set, the smooth line obliterated toward l>ase; antenme about as long as 

 the head and prothorax, somewhat thick and strongly incrassate, the tenth 

 joint not (^uite as long as wide. Prothorax much narrower than the head, as 

 long as wide, obtusely constricted at basal fourth, the sides broadly rounded 

 anteriorly, widest at apical fourth; collar well developed, finely but very 

 deeply constricted at base ; punctures fine, deep and close. Elytra three-fourths 

 longer than wide, twice as wide as the prothorax, the sides subparallel and 

 feebly arcuate; apex narrowly rounded; humeri broadly exposed at base; scu- 

 tellar impression feeble but distinct; omoplates large and feeble; punctures 

 deep, very close-set, moderately coarse, becoming very fine toward apex. Ah-
