(Champion). 
Head strongly produced between the eyes. Antenne strongly compressed, attenuated 
at the apex; the third to the seventh joints cristate; front finely sulcate, its anterior 
surface faintly carinate. Thorax subconic, slightly broader than long in the male, 
rather more transverse in the female ; sides straight and converging from base to apex 
in the male, more obliquely converging at the apex in the other sex; transversely 
convex, slightly depressed on the hinder disc, coarsely and irregularly punctured ; 
medial line with a fine longitudinal groove. LElytra slightly dilated from the base 
towards the apex, the latter subacutely rounded, broadly emarginate at the suture ; 
sides finely, the apical margin rather more strongly, serrulate; apical border in the male 
distinctly dilated ; each elytron with eight regular rows of punctures; the second, 
fourth and sixth interspaces costate, the third behind the middle, and the fifth at its 
base and apex, slightly elevated. 
18. Uroplata elegantula. (Tab. IV. fig. 14.) 
__Anguste elongata, rufo-testacea, subtus nitida, supra subnitida, antennis piceis; thorace transverso, rude 
rugoso-punctato ; elytris fere parallelis, apice rotundatis, lateribus minute serrulatis, margine apicali irre- 
gulariter serrato et ad suturam emarginato; utrisque octo-seriato-punctatis, stria octava medio interrupta, 
interspatiis alternis costatis ; vitta lata suturali, ante apicem obsoleta, piceo-eenea instructis.

Thorax about one third: broader than long ; sides straight and nearly parallel from 
the base to just beyond the middle, thence rounded and converging towards the apex, 
the anterior angle armed with a short, subacute, oblique tooth; upper surface convex, 
transversely excavated on the hinder disc, coarsely rugose-punctate. Elytra parallel,
