the third joint nearly twice as long as wide and three-fifths as long as the 

 fourth ; anterior tarsi slender, much shorter than the tibiae ; fifth ventral 

 segment short, broadly arcuate at apex, the surface broadly, indefinitely im- 

 pressed ; genital armature sinuate at apex, the lateral angles broadly rounded. 

 Length 7.3-8.5 mm. ; width 2.(J-3.2 mm.

When compared with the female of murrayi, the corresponding 

 sex of this species differs in its longer antennae with shorter third 

 joint, in the less exposed elytral humeri, in the widely diffused im- 

 pression of the fifth ventral segment, in the broader, feebler median 

 sinuation of the genital armature, and in its smaller size. The 

 elytra of murrayi are more strongly dehiscent toward apex, and 

 have the sides parallel, so that they are widest at about the middle, 

 while in the present species they are subinflated behind the middle, 

 the sides being more convergent toward base. 



A. COllCOlor n. sp. — Oblong-oval, rather strongly depressed, brown and 

 polished throughout ; pubescence sparse. 



Female. — Head rather strongly and densely punctate, with a distinct median 

 longitudinal sulcation ; eyes moderate, separated by fully two-fifths more than 

 their own width ; antennae scarcely one-half as long as the body, slender, 

 filiform, the third joint but slightly longer than the second and one-half as 

 long as the third. Prolhorax one-half wider than long ; sides parallel and 

 nearly straight in basal three-fifths, then somewhat abruptly convergent and 

 feebly arcuate to the truncate apex ; basal sin nations very feeble, the broadly 

 rounded median lobe more prominent posteriorly than the lateral portions ; 

 basal angles right and distinctly blunt ; disk almost evenly but feebly con- 

 vex, with a very imperfectly defined median impunctate line, very finely, 

 sparsely punctate, the basal foveae almost obsolete. Elytra fully four times 

 as long as the prothorax and about one-half wider, rather obtusely ogival in 

 apical third and gradually strongly dehiscent ; sides parallel and very feebly 

 arcuate behind, straight toward base, the humeri rather broadly exposed ; 

 disk rather strongly flattened toward the suture, the first three or four strise 

 distinctly impressed ; strial punctures fine ; intervals finely, unevenly and 

 sparsely punctate. Abdomen very minutely, extremely sparsely punctate. 

 Legs rather short, the tarsi about as long as the tibife ; basal joint of the 

 posterior quite distinctly shorter than the remainder. Fifth ventral segment 

 short, broadly, indefinitely but strongly impressed ; genital armature sinuate 

 in the middle, nearly as in hrunneus. 



Length 8.5 mm. ; width 2.9 mm.

This species is distinguishable at once from murrayi by the very 

 short third antennal joint of the female, and from hrunneus by its 

 much narrower, more depressed form and smaller eyes of the same
