somewhat indistinct ; prothorax strongly scabrose and clothed with 

 a long, fine, greyish or sub-flavescent upright pubescence without 

 an admixture of scales ; scutellum closely scaly ; elytra deeply 

 sulcate, the sulci filled with greyish-flavescent or flavescent closely 

 set scales, the costae are smooth ; propygidium with a narrow 

 band of flavous scales ; pygidiuin somewhat convex in the centre, 

 covered with a velvety black-brown tomentum reaching from the 

 base to two-thirds of the length, and thence to the apex with closely 

 set, small yellow scales ; occasionally there is a faint median longi- 

 tudinal line of scales reaching the base ; pectus and legs densely 

 hairy ; hind femora well developed and without any trochanterine 

 spine, but with the inner apical part of the knee toothed ; hind tibia? 

 grooved underneath and with the upper inner margin notched twice 

 between the knee and the median part, the two notches being sepa- 

 rated by a plain, somewhat truncate tooth, the lower edge from the 

 excavated part right down to the apex, and also the upper edge are 

 plainly serrate, and there is a mucronate tooth on each side of 

 the apex, the lower one being longer than the upper, no apical 

 spur; inner claw nearly half the length of the outer. 



The female differs from the male in the less dense rows of more 

 hair-like scales on the elytra, and the pygidium bears two basal 

 brown velvety patches. 



The nearest ally of this species is the small development of 

 H. armipes, which I erroneously described as H. mimus (Catal. i., 

 p. 726), and which differs by the vestiture of the pygidium and 

 the absence of trochanterine spine. 



Length 4^-6 mm. ; width 3-4 mm. 



The species should follow H. armipes, Cat. i., p. 725.

Heterochelus jucundulus, n. spec. 



Male : Black with a faint metallic tinge, but also occasionally 

 rufescent ; elytra and legs red ; anterior margin of clypeus quadri- 

 denticulate; prothorax covered with deep scabrose punctures, clothed 

 with a very long erect pubescence, but having also a few appressed 

 squamose hairs ; scutellum covered with dense whitish flavescent 

 scales ; elytra moderately deeply bi-sulcate longitudinally on each 

 side, the sulci filled with lanciform, not closely set whitish scales 

 which are l'eplaced on the sides by more hair-like appressed ones; 

 propygidium with a narrow band of yellowish scales ; pygidiuin 

 densely scaly ; pectus and legs pubescent ; hind femora strongly 

 developed, trochanters produced into a moderately long, basal spine,
