Hetekochelus bisignatus, Blanch., 

 Catal. Coll. Entom. Mus. Par., p. 65. 



Male : " Size of H. hinotatus but a little larger, under side with white 

 hairs, clypeus with four strongly prominent teeth, the two median 

 ones being set close to each other ; prothorax punctate, setose, deeply 

 sulcate behind in the centre ; scutellum clothed with yellow scales ; 

 elytra plane, slightly tri-costate, with the intervals tilled with 

 fulvous scales, pygidium flavescent and having two fuscous patches ; 

 legs piceous, posterior ones moderately inflated, femora simple, tibiae 

 not dentate, angular at apex. 



Length hardly 5 mm." 



The type has unfortunately lost its hind legs, but from the 

 description given by Blanchard one can assume that it belongs to 

 the group of H. analis fraternus, &c., and has an apical spur in the 

 posterior tibiae. The two fuscous patches on the pygidium are very 

 noticeable.

 •pubescent ; prothorax closely scabroso-punctate, but with the punc- 

 tures deeper and simple in the posterior part, clothed with short, 

 sparse, sub-appressed slightly flavescent hairs, it is distinctly convex 

 and the median groove is deep and disappears only at a short 

 distance from the apical margin ; scutellum clothed with squamulose 

 greyish- white hairs ; elytra a little attenuate laterally towards the 

 apex, but not strongly sinuate below the humeral part, each one has 

 two costse on the disk, the inner one being the more distinct, and the 

 humeral callus is also costate, the three intervals are more or less 

 densely filled with appressed whitish or slightly flavescent hairs 

 which are more numerous on the juxta-sutural interval, but which 

 in the posterior part and along the apical margin turn into flavescent, 

 somewhat rounded scales, in the fresh examples the lateral margin 

 has also a line or narrow band of squamiform hairs, but these hairs 

 are, as often as not, ruljbed off, and the intervals are seen to be
