Heterochelus promontorii, n. spec. 



Male : Black, with the elytra chestnut-red or dark bronze ; the 

 scutellum, the propygidium, and the abdomen are clothed with dense 

 yellowish scales, but the pygidium is glabrous and shining, and the 

 elytra have a sutural band of similar scales beginning at about 

 the median part and continued on the apical, and a discoidal one 

 reaching from the base to the middle ; head and prothorax scabrose, 

 very briefly pubescent and not scaly, clypeus dentate on each side 

 but not denticulate in the centre ; elytra distinctly bi-costulate on 

 each side, second costa disappearing at about the median part, the 

 intervening space is filled with the scales, which are not very dense on 

 the discoidal one or along the outer margin ; hind femora very robust, 

 the trochanters are simple, but the inner tooth of the knee is 

 developed into a distinct spine, the short hind tibiae are curved, 

 ampliated, grooved underneath and strongly dentate on each side of 

 the base, but have the outer tooth set further from the base than the 

 inner, the inner mucro is long and curved, almost hamate ; claws as 

 in H. viridicollis. 



Female : Like the male, and also with the pygidium without scales 

 and sub-glabrous ; the scales on the elytra are replaced by sub- 

 squamose hairs which are not conspicuous. 



This species is not unlike H. rufimanus, which has also the 

 denuded pygidium, but it differs in the sculpture of the elytra and 

 in the shape of the hind tibiae.

Heterochelus tristis, n. spec. 

 Male : Black, somewhat shining but clothed with a black pubes- 

 cence, shorter on the elytra than on the prothorax where it is 

 somewhat villose ; pygidium very convex at the base and covered 

 with a velvety black tomentum ; head and prothorax closely scabroso- 

 punctate, clypeus straight, angular on each side, but with the angles 

 not reflexed ; prothorax w^ithout scales ; scutellum occasionally scaly, 

 the scales flavescent ; elytra very slightly bi-costulate on each side, 

 closely and somewhat roughly punctured, covered with a fuscous 

 pubescence but having in the juxta-sutural, and also on the discoidal 

 intervals a few slightly flavescent sub-squamose hairs disposed 

 obliquely ; propygidium not distinctly scaly, but sides of the abdomen 

 with distinct orange squamose hairs ; hind femora robust, spine of 

 trochanters fused with the thigh but projectmg a little towards the 

 median part, and at a short distance from it there is a sub-hamate, 

 distinct spine ; hind tibiae compressed, having underneath a sub-
