the genus; it is near D. coimiiis. l)Ut slightly smaller, prothorax not quite so 

 gibbous, and the discal striae are shallower, although the lateral ones are quite 

 as deep; the legs are also darker; from D. intoiisus it differs in being smaller, the 

 prothorax more gibbous and with line sculpture very dift"erent, and the legs 

 entirely dark. 



DITROPIDUS DISCICOLLIS sp. nov. 



<S Brassy, under surface with a slight greenish gloss, labrum and basal 

 half of antennae reddish, parts of tibiae obscurely diluted with red. Moderately 

 clothed with white pubescence, sparser on middle of pronotum than elsewhere. 



Head with rather dense punctures, becoming coarse on clypeus, with a 

 rather wide median line. Eyes separated slightly more than the length of basal 

 joint of antennae. Prothorax scarcely twice as wide as the median length, some- 

 what gibbous in front, feebly depressed on each side near base ; with fairly 

 numerous minute punctures in middle, becoming larger on sides and apex. 

 Elytra subquadrate, shagreened throughout ; striae deep and well defined on 

 sides, feeble but with fairly distinct punctures elsewhere ; interstices with small 

 asperate punctures. Leys not very long and (for the genus) rather thin. Length, 



2 -25 mm.

io<)57- 



Structurally close to the preceding species, but the jirothorax not shagreened, 

 and the punctures on its middle smaller and quite round ; the median line on the 

 head is also deeper and wider. 



Prothorax inibescent, Ei,>tk.\ glabrous. 

 DITROPIDUS CUPRICOLLIS sp. nov. 



S Bronzy, prothorax coppery bronze, labrum palpi and parts of antennae 

 and of legs flavous. Head, prothorax, under-surface, and legs with white 

 pubescence. 



Head with crowded and rather small punctures. Eyes separated the width 

 of front of clypeus, Prothorax about twice as wide as the median length ; punc- 

 tures small and not very dense. lilytra slightly narrowed posteriorly: with 

 rows of fairlv large punctures, becoming larger and set in deep striae at the sides ; 

 interstices very feebly rugose. Front leys slightly longer than hind ones. Length, 



3 "4 mm.
