Prothorax cylindrical, not margined at sides except for a very 

 short distance at the base angles ; base with a short, broad, 

 sinuate, feebly reflexed lobe. Scutellum very short and broad, 

 scarcely entering the elytral disc, its posterior margin broadly 

 arcuate. Elytra narrow, parallel, a little wider than the thorax , 

 side margins not serrulate. Prosternum broadly convex, more 

 strongly so between the coxae, squarely truncate in front, in- 

 tercoxal process slightly dilated behind the coxae, then gradu- 

 ally pointed. Mesosternum deeply impressed or divided 

 throughout its length, the impression or excavation occupied 

 anteriorly by the tip of the prosternum, but open for a short 

 distance posteriorly. Front coxae separated by about their own 

 widths ; middle coxae slightly more distant. Metasternal epi- 

 sterna moderately wide, about two and one-half times as long 

 as wide. Hind coxal plates not much dilated internally, the 

 posterior margin concave and only a little oblique. 



Ventral segments 2-4 equal, first conspicuously and fifth 

 slightly longer, sutures straight, the first fine but distinctly im- 

 pressed. 



Legs moderate, tarsi subequal in length to the tibiae, basal 

 joint distinctly longer than the second, joints 1-4 lobed beneath; 

 claws simple. 



A. cylindricollis n. sp. 



Cylindrical, convex, viridi-aeneous, elytra distinctly cuprascent, clothed 

 thinly above and beneath with fine whitish pubescence, the hairs inclined 

 on the elytra, a little longer and erect on the head and prothorax. 



Head exactly equal in width to the prothorax, front convex, densely 

 punctate and with two very small tuberculiform prominences at middle, 

 between which is a slight impression. Antennae equal in length to the 

 prothorax and attaining the middle of the latter; joints I and 3 mod- 

 erately elongate, 2 and 4 shorter, 4 triangular, as long as wide, 5 to n 

 transverse, their lower edges feebly then rapidly oblique to base. 



Prothorax cylindrical, a little wider than long, sides straight and 

 parallel from base to apex, disk a little more strongly convex antero- 

 medially, and with a short ante-median impression; surface nearly evenly 

 punctate, the punctures separated by their own diameters or rather 

 more, the interstices polished ; hind angles not in the least carinate. 

 Elytra a little wider than the thorax, parallel to apical third, apex ob- 

 tusely rounded or subtruncate, surface rather densely punctate and 

 vaguely finely striate, the punctures of the intervals similar to and much 

 confused with those of the striae. Beneath rather closely punctate and
