Mr. J.S. Baly on the Classification of the Kumolpide. 149 
Genus Apoxus, Kirby. 
Bromius, Chevy., Redtenb. 
Body oblong, subcylindrical, clothed above and beneath with adpressed 
hairs. Head moderately exserted, perpendicular ; antenne subfiliform, 
robust, first joint incrassate, second rather shorter than the first, sub- 
incrassate, ovate, the third equal in length to the second, the fourth 
somewhat longer; eyes subprominent, entire ; terminal joint of palpi 
ovate ; mentum with its anterior margin concave. Thorax subcylin- 
drical, its lateral border entirely obsolete. Edyta much broader than 
the thorax, closely punctured. Legs stout ; thighs moderately thickened, 
unarmed beneath; basal joint of tars: scarcely shorter than the two 
following united ; claws bifid. Prosternum transverse, its anterior mar- 
gin separated from the episternum by a deep groove. Mesosternum 
transverse, its apex truncate or obsoletely concave. 
Type, Adoxus vitis, Linn. Europe and North America. 
The presence of the sutural groove between the prosternum and 
episternum at once separates this genus from all its congeners. 
Two well-known species, vitis and obscurus, are natives of middle 
and southern Europe ; the first is also found in Canada and the upper 
portion of the United States. A third species, undescribed, has been 
taken by Mr. A. Adams in Japan. 
Genus Aorta, Baly. 
Body oblong, subcylindrical, closely covered above and beneath with 
adpressed silky hairs. Head exserted, perpendicular; antenne sub- 
filiform, moderately robust, first joint incrassate, second nearly one 
half shorter than the first, ovate, third thickened towards the ex- 
tremity, longer than the second, but shorter than the fourth; eyes 
entire, prominent ; mentwm with its anterior border deeply concave ; 
terminal joints of palpi ovate, narrowed and acuminate towards the 
apex. Thorax subcylindrical, its lateral border entirely obsolete. 
Elytra much broader than the thorax, surface closely punctured, some- 
times impressed with longitudinal striz. Legs moderately robust; 
thighs subincrassate, unarmed beneath; basal joint of tars? nearly 
equal in length to the following two united ; claws bifid. Prosternum 
transverse, its anterior margin continuous with that of the episternum. 
Mesosternum transverse or transverse-quadrate, its apex bifureate. 
Type, Aorta nigripes, Baly, huj. op. i. p. 28 (Adoxus). China; Siam; and 
Malacca. 
This genus closely resembles Adowus; the absence of the sutural 
groove between the prosternum and its episternum will, without the 
least difficulty, separate the two. The species, three in number, are 
Asiatic ; two have a wide range, being found in Malacca, Siam, and 
also China; the third has as yet been only sent from Siam.
