in the middle behind), the prothorax (a lanciform mark on the disc 

 excepted), the apical portion of the abdomen, the apices of the femora, 

 the tibiae, and the tarsi to near the tip, testaceous or pale testaceous ; 

 the elytra fusco-violaceous, with the outer margin, apex, and the 

 suture from a little below the base, wliitish ; finely pubescent. Head 

 large, broad, densely, minutely punctate, shallowly foveate between 

 the eyes; antennae long, feebly serrate. Prothorax transverse, 

 closely, minutely punctate. Elytra comparatively short, wider than 

 the prothorax; densely, finely, distinctly punctate.

One male. In this minute species the elytra are fusco- 

 violaceous, with the suture (to near the base), outer margin, 

 and apex whitish, the dorsal stripe being sHghtly sinuate 

 externally ; the femora are black, with the apices abruptly 

 testaceous and coloured like the tibiae ; and the antennae 

 are rather elongate. The elytra are somewhat distorted 

 in drying, but the sculpture and markings are clearly 

 visible.

The type of this species is a female; the fragmentary 

 remains of the second specimen mentioned by Gorham 

 include the anterior tarsi, sufficient to indicate the male 

 sex. A. albolimbatus is a small, narrow form, with the 

 anterior half of the head, the margins of the prothorax 

 completely, and the sutural, outer, and apical margins of 

 the elytra, whitish or pale testaceous, the rest of the head 

 and prothorax being black and that of the elytra aeneo- 

 piceous ; the body beneath and the legs (the tarsi and apices 

 of the tibiae excepted) are testaceous; and the elytra 

 and the tip of the abdomen are strongly nigro-setose. 

 The last-mentioned character separates the present species 

 from the northern A. cinctus, Lee. The specific name 

 limbatns is preoccupied and a new one is therefore required.
