Heteeochelus placatus, n. spec, 

 Plate XLII. fig. 43. 



Male : Very closely allied to H. ictericus ; the shape, sculpture, 

 and disposition of the scales and hairs are similar, but the scales are 

 more yellow or even deep ochre, and the elytra are very slightly bi- 

 costate, but the shape of the hind tibiae is different ; the trochanters 

 of the hind femora are long and sharp, and the tooth in the inner part 

 of the knee is strong, but the hind tibiae are only moderately deeply 

 grooved at the base underneato, and feebly dentate near the knee, 

 there is a stronger sub-basal tooth on the upper margin, and a 

 strongly developed triangular one on the lower margin, at about the 

 middle of the length, and the tibia is very little scooped from there to 

 the apex ; the lower margin is moderately serrate, and the apical 

 mucro is strong and curved ; no apical spur ; inner claw half the 

 length of the outer which is simple. 



Female : Black, with the elytra testaceous, clothed with appressed, 

 not dense, flavescent hairs, and having a few round, yellow scales on 

 the posterior edge of the elytra ; pygidium clothed with yellow 

 scales.

 clypeus very indistinctly bi-dentate in the centre, but with the angles 

 sharp ; head and prothorax scaln-oso-punctate, clothed with partly 

 appressed, partly erect fiavous hairs, and having a more or less 

 distinct basal band of elongate scales, which also fill partly the 

 posterior part of the longitudinal median groove ; scutellum clothed 

 with lanceolate scales ; elytra non-costate, having only a basal 

 depression in the inner part of the humeral callus, and clothed with 

 round scales ; propygidium and pygidium covered with very minute 

 contiguous scales ; hind femora strongly ampliate and having beneath 

 a long, somewhat thick, horizontal spine l)eginning at about the 

 median part of the thigh, the spine being the prolongation of the 

 trochanter which is fused with the thigh, at a short distance from
