part, and an apical band of similar scales ascending the posterior part 

 of the outer margin ; legs piceous, hind femora occasionally red ; 

 antennal joints, except the club, rufescent ; clypeus with three sharp, 

 equal teeth ; head and prothorax scabroso-punctate and clothed with 

 a short, erect, greyish-black pubescence ; prothorax shaped as in H. 

 detritus, but with the basal transverse impressions without a shai*]^) 

 ledge; scutellum briefly but densely pilose; elytra turning sometimes 

 to dark chocolate-brown, ver}"^ closely sub-scabroso-punctate, and with 

 the space between the discoidal patch and the apical band clothed 

 with a somewhat velvety fuscous tomentum ; propygidium and 

 pygidium without scales, glabrous ; pectus and abdomen with a fine, 

 short, greyish pubescence ; hind femora with a sub-apical hoi'izontal 

 spine beneath, knees not dentate; hind tibiae short, compressed, 

 produced inwardly into a very long, curved process, and having near 

 the knee a triangular tooth ; the apical spur is situated at the base 

 of the hooked inner process and is distinct ; the four l)asal joints of 

 elytra are regularly triangular and very compressed; inner claw more 

 than half the length of the outer and both slightly cleft. 



Female : The clypeus is similar to that of the male, and the legs 

 and abdomen are more rufescent ; the prothorax is clothed with 

 longer hairs which are also more flavescent, and nearly the whole 

 surface of the elytra is covered with flavescent scales except the 

 humeral callus, and two discoidal longitudinal bands which are 

 somewhat denuded. 



Length 7-8 mm. ; width 4-4^ mm.

Male : Allied to the preceding species, and having likewise the 

 clypeus sharply tri-dentate at tip ; the shape, sculpture, and colour 

 of the prothorax are similar, but the basal transverse impressions 

 are a little deeper ; the scutellum is non-scaly ; the elytra are more 

 attenuate laterally towards the apex, and they have a broad juxta- 

 sutural band of yellow scales reaching from the base to the apex 

 where it unites with a marginal one of nearly the same width ; the 

 propygidium and pygidium are glabrous ; the hind femora are 

 very large, sprinkled with numerous scar-like punctures, and are 

 shaped as in H. 'podacjricus, but the hind tibia are a little longer, less 

 curved, less dilated inwardly at apex, with the apical process longer
