joints each about equal in length to the first, each slightly 
decreasing in length, slightly thickened at their apices, following 
four moderately thickened, nearly equal, submoniliform, eleventh 
rather longer ; eyes entire. Thorax transverse, subcylindrical in 
front, gibbous, strongly tuberculate on disc, lateral margins 
distinct, strongly produced, their outer edges sometimes minutely 
toothed. Elytra much broader than the thorax : surface rugose- 
punctate, covered with adpressed curved scales, intermixed with 
tufts of suberect similar scales. Legs robust ; femora beneath with 
a short stout tooth ; tibia; curved ; claws bifid. Prosternum 
transverse, quadrate, separated from episternum by a deep groove. 
Mesosternum short, transverse, apex concave. 
Can be distinguished by the produced lateral border of the 
thorax. In the typical species, A. mouhoti, Baly, the thorax 
is dilated at the sides ; in the other known species the lateral 
margins are finely serrate.

Black, subnitidous, closely covered with large, curved, concave, 
fulvo-fuscous scales. ITead short, sub- 
globose; antennae fusco-fulvous, scarcely 
longer than the thorax. Thorax one- 
third as broad again as long, the 
posterior four-fifths of the lateral 
border strongly produced, the anterior 
fifth ill-defined, the outer edge armed 
with minute teeth ; surface of disc 
deeply punctured, elevated into two 
large parallel conical tubercles, two 
small patches of scales on the anterior 
border together with a somewhat longer 
patch immediately behind each of the 
conical protuberances on the disc, 
black. Elytra deeply punctured, clothed 
with fulvo-fuscous intermixed with 
similar black and white scales ; each

Group E UBliA CHINI. 
Characters of Pseudo colaspini , but with the anterior margin of 
thoracic episternum concave. It is on this character that Baly 
has separated the Eubrcichini from the Pseudocolaspini. The group 
contains two genera which can be tabulated as follows : —
