longer tlian is usual in the genus, but as the joints of the club are not very lax, 

 and the prothorax is glabrous, it was not referred to Elaphodes. 



DITROPIDUS NIGRIVENTRIS sp. nov. 



Flavous, elvtra slightly paler than pmthorax, metastennim and abdomen 

 black, base and suture (both very narrowly) of elytra, scutellum and club infus- 

 cated. Under-surface and legs sparsely pubescent. 



Head with rather sharply defined punctures ; median line feeble. Eyes large 

 and close together. Prothorax more than twice as wide as the median length, 

 somewhat gibbous in front, with a rather shallow depression on each side 

 obliquely directed from .scutellar lobe to front angle (but touching neither) : with 

 rather sparse and distinct, but small punctures in middle, becoming larger and 

 more numerous on sides. H!\tni moderately long; with rows of rather large, deep 

 jiunctures, on tlie sides set in rather deep striae. Length, 2-2 -25 mm.

T am satisfied that the two specimens before me belong to but one species, 

 they both have the abdomen foveate at the apex, although the fovea seems too 

 small and shallow for a female, the abdomen is not depressed in the middle, 

 however, and in consequence the tip of the pygidium is not brought forward, this 

 being tv])ical of females ; the front legs are not longer than the hind legs (on a few 

 species the legs are not sexuallv \-ariablc in length) : but the distance between the 

 eves of the type is slightly less than the length of the basal joint of the antennae, 

 on the second specimen it is slightly more than the length of that joint, the differ- 

 ence is not great, but it is at once apparent on the specimens, gummed side by 

 side on a card, and is accompanied by a difference in size of the eyes. The 

 difference may be varietal : if sexual, the type must be a male, and the other 

 specimen a female. 



DITROPIDUS LONGUS sp. nov. 



d Flavous, two spots on prothorax, scutellum, suture ("very narrowly) 

 base and a transverse post-median fascia ('sometimes broken up into spots) on 

 elytra black ; second to fourth segments of abdomen and base of pygidium more 

 or less deeply infuscated or blackish, club and tarsi feebly, if at all, infuscated. 

 Under-surface and legs with sparse, white pubescence, head still more sparsely 

 clothed. 



Head with dense, sharply defined punctures of nroderate size, becoming 

 larger on clypcus; median line very feeble, Eyes very widely separated. Pro-
