PRONTSSA, gen. nov. 



(^ pedum quatiior anficorum tarsi articulis trihus dilatatls'. Labrum 

 maxime eJongafum, dcntis ([uinque validis instructum. 



This genus ia founded on an Indian species having the remark- 

 able character in the (^ of dilated tarsi to the four anterior legs. In 

 this respect it agrees with Heptadonta, having the dilated joints of the 

 same form and same dense hairy vestiture beneath. But the labrum 

 differs in being extremely elongated (as long as in Oxycheila) even in 

 the $ , with only five very strong, almost claw-like, teeth. The thorax 

 differs also in being very small, strongly constricted in front and 

 behind, with much rounded central portions. The elytra are covered 

 with strong vermiculate rugae. The general form of body is that of 

 the S. American OdotitocheilcB, or rather the Fentacomiae. The tarsi 

 are not grooved. 



Peoxtssa nodicollis, sp. n. 



Elongata, gracilis, supra herhaceo-viridis, suhaureo-micans, passim 

 rugulosa ; subius viridi-ceneo splendens, lateribiis igneo-oBneis, nudis ; 

 labro Jlavo-tesfaceo, vitta mediana viridi ; pedibus testaceo-fidvis^elytris 

 utrinque guttis marginalibus tribus albis. Long. Q\ lin. ^ . 



The head is deeply concave between the eyes, and finely striated 

 over its whole upper surface. The labrum quite covers the mandibles 

 except their apices ; the palpi are pale testaceous, with the terminal 

 joints only a little darker. The thorax is closely and irregularly 

 wrinkled, chiefly in a transverse direction. The white spots of the 

 elytra are situated — one at the humeral angle, a second in the middle 

 of the side, and the third at the external apical angle ; none of them 

 touch the margin. The body beneath is destitute of pubescence, but 

 the coxae have a patch of white hairs.

Similar in form to O. margineguttata, but a little more elongate, the 

 cylindrical thorax without constriction, and the elytra evenly convex 

 without depressions. The labrum is rather elongate (especially in
