Species of Histevidx. 429 



rounded off, stria complete, very fine behind the head, sinuous 

 laterally, deep behind the middle, and leaving at this 

 point a widened margin ; the elytra punctured like the thorax, 

 narrowly smooth at the base, a little reddish at the humeral 

 angle and narrowly at the apices ; the propygidium and 

 })ygidium are evenly, not thickly punctured ; the pro- 

 sternum — punctures large and scattered, bistriate, striae well 

 marked and slightly divergent in front, somewhat wide apart, 

 shortened a little at the base, anteriorly reaching beyond the 

 middle ; the mesosternum obtuse, similarly punctured and 

 marginate, margin interrupted at the metasternal suture, the 

 sutural area is free from punctures ; the metasternum has a 

 lateral stria for two-thirds its length, which is punctate on its 

 inner edge, the surface has a finely and more scattered punc- 

 tuation than the mesosternum ] anterior tibi» 5-dentate, inter- 

 mediate 6-spinose, 1 basal small, 3 strong placed together 

 in the middle and 2 at the apex ; the hind coxas are very 

 peculiar, they are swollen and tuberculate, the base of the 

 tibia being inserted apparently on the apex of a cone. 



This species may be placed next to T. basalts, Lew., from 

 which it is scarcely separable on the upper surface ; but the 

 prosternum in T. australis is longer, with the stride well 

 marked and nearly straight, and the mesosternum is obtuse 

 anteriorly. In T. hasalis the mesosternum is somewhat 

 acute, and there is no peculiarity in the cox£e.

Acritus LigJitfooti, sp. n. 



Ovalis, convexus, brunneus, nitidus ; auteunis pedibusque con- 

 coloribus ; elytris antice punctatis, postice couspicue strigosis ; 

 pygidio dense et minutissime puuctulato ; prosterno bistriato, 

 striis rectis divaricatis, basi conjunctis. 



L. 1|, c. 1| mill. 



Oval, convex, brown, shining ; the head even between the 

 eyes, feebly and sparsely punctulate, epistoma rugosely punc- 

 tate ; the thorax — marginal stria complete in front and at the 

 sides, punctuation shallow, not close, finest before the scu- 

 tellum ; the scutellum smooth and obvious ; the elytra — around 

 the scutellum and a little part down the suture the punc- 

 tuation is very fine and sparse, on the dorsal area and sides 

 it is larger, but similar to that of the thorax, with a dense 

 and conspicuous strigose sculpture at the apex, which extends 

 up the elytra for nearly one third of their length, gradually 

 giving way to the punctures ; the propygidium and pygidium 

 are densely covered with a microscopic punctuation, the latter
