8/. Accia lucida, Curt. 



Nitide testacea, minute punctulata, capite ferrugineo, elytris subcupreis stria- 

 tis (Tab.XLI. fig. 6.). 



Length 4£ lines, breadth 2. 



Bright ochreous, smooth and very glossy : head and clypeus concave, with a small elevation 

 in the centre ; finely punctured, with a rosy tinge: thorax more faintly punctured and 

 convex : scutel not punctured on the disc : elytra paler, testaceous, with a faint green- 

 ish tint, more rosy at the base, with 9 punctured stria; on each vanishing at the apex; 

 the interstices convex and sparingly punctured; a few scattered hairs beneath; pectus 

 punctured : tibiae inclining to ferruginous, especially the tips. 



A single specimen from Port St. Elena. It has the habit of Omalopliu, and 

 is distinguished from the preceding genus by its exposed labnim, differently 

 formed palpi and antennae, the length of the basal joint of the tarsi, which are 

 not velvety beneath, and by its simple claws.

 head and clypeus strongly punctured, the latter lunate, with a distinct curved suture 

 at the base, leaving the head of a transverse lenticular form: thorax very convex and 

 regularly punctured, rather transverse, semiovate, broadest at the base; scutel mode- 

 rate, semioval, punctured: elytra broader than the thorax, only twice as long, and 

 exposing the pygidium, rather rugose with punctures; at the middle is a subcordate 

 fovea, with an impression beyond it, extending round the apex, and forming an apical 

 elevation: underside with variolated punctures and minute depressed white hairs: 

 legs punctured and similarly clothed, stout, hinder elongated; tibia,, anterior with the
