Aethropterus Kiebyi, Westw., 



Proc. Ent. Soc, 1864, p. 189 ; Thesaur. Entom. Oxon., p. 79, 

 pi. xvi., fig. 1. 



Chestnut brown, glabrous, shining ; antennge long, the transverse 

 joints of equal width, except the second one, closely set, and hardly- 

 pubescent ; head with two deep impressions on the vertex close to 

 the eyes ; prothorax subelongato-quadrate, marginate, slightly 

 sinuate above the basal angle and with a lateral impression on each 

 side, smooth, not fringed with hairs, and with a narrow median 

 longitudinal groove reaching neither base nor apex ; elytra straight 

 laterally and not much broader at the base than the prothorax, but 

 gradually ampliated till the apex, where they are not truncate, but 

 gradually rounded off, quite smooth and hairless, with an elongated 

 flavescent lateral patch above the subtuberculated fold, the posterior 

 margin is also narrowly flavescent, and the suture has a very narrow 

 line of the same colour ascending from the apex to a little past the 

 median part ; the tibiae are moderately broad and compressed, and 

 the anterior ones a little arcuate inwardly. 



The only specimen that I have seen (male) differs a little from 

 the figure given by Westwood. The two impressions on the vertex 

 are not in front of the eyes, but at about the median part and close 

 to them ; the prothorax is of the same colour as the head and elytra, 

 and not flavescent, and has no trace of two discoidal round impres- 

 sions, and the elytra are not truncate behind, but sloping and 

 gradually rounded from the posterior subtuberculated ^jart of the 

 fold. There is little doubt however that the two specimens belong 

 to one species. Length 7 mm. ; width 3 mm.

Heteropaussus, Jas. Thoms. 



Head elongato-quadrate, not dilated behind the eyes, but slightly 

 constricted there and prolonged into a neck not much narrower than 

 the head ; maxillary palpi quadri-articulate, second joint as long as 

 the two following, apical one subacuminate ; maxillge with a very 

 short, subrudimentary outer lobe, inner lobe hooked at tip and pluri- 

 dentate along the inner edge ; ligula convex, broad, ovate, convex 

 outwardly and carinate in the centre ; labial palpi triarticulate, last 

 joint swollen, subelongato-ovate and subacuminate ; labrum sharply 

 triangular ; antennae compressed, ten-jointed, basal joint subelon- 

 gato-quadrate, the other joints transverse, partly or completely fused
