A 1 . Anterior tibiae uni-dentate. 



Club of male 6-jointed, fourth joint of pedicel laminate . . (Archocamenta). 



Head and median part of prothorax inf uscate ; elytra straw- 

 colour, antennas reddish pilosa. 



Camenta (Eucamenta) castanea, Bohem., 

 Insect. Caffr., ii., p. 107. 

 Chestnut-brown, shining, club of antennae flavescent ; head and 

 -clypeus covered with nearly contiguous punctures, clypeus in the 

 shape of a broadly truncate cone with the margins raised in the male, 

 while in the female the anterior outer angles are rounded and the 

 anterior margin very slightly sinuate, the clypeal ridge is ante-median, 

 transverse, and plainer in the male than in the female, the 8-jointed 

 flabellate club of the $ is equal to two-thirds of the length of the 

 whole head, the inner joint is two-thirds of the length of the other 

 joints ; in the $ the club proper is 3-jointed and much shorter than 

 in the $ , but the three joints preceding, i.e., the seventh, sixth, and 

 fifth, are plainly laminate but decrease in length, the seventh joint 

 being half the length of the following one, and the sixth and fifth 

 decreasing in proportion ; prothorax narrowed laterally in the $ 

 from near the median part to the anterior angle which is strongly 

 produced, nearly straight thence to the posterior angle, which is 

 plainly rounded, moderately convex in the central part of the disk, 

 covered with somewhat small, round punctures divided by a smooth 

 interval equal in width to their own diameter ; in the ? the pro- 

 thorax is broadly rounded and ampliated laterally and equally 

 narrowed towards the anterior and posterior parts ; scutellum 

 sharply ogival, depressed, and punctulate on each side of a 

 median longitudinal raised line ; elytra plainly wider at the base 

 than the basal part of the prothorax, not sinuate laterally past the 

 shoulders, humeral callosity very little pronounced, but slightly 

 more so in the ? than in the $ , moderately convex and covered 

 with slightly rugose, unequal punctures very closely set, and having 

 in the dorsal part three geminate punctulate striae the intervals of 

 which are slightly costulate in the $ but not in the $ , the two lateral 

 striae or costules respectively are very faint ; the propygidium is 

 closely punctate but covered for the greatest part by the elytra; 

 pygidium plainly convex in both sexes, and having an apical fringe 

 of long, flavescent hairs ; abdomen convex, each abdominal segment 

 deeply punctured and with a transverse series of flavescent hairs ; 

 pectus closely punctured and moderately densely clothed with long, 

 flavescent hairs ; anterior tibiae bi-dentate outwardly, and with the
