400. Colobopsis testacea, u. sp. 



2 . Pale testaceous yelloM", \\ith only a few scattered erect 

 pale yellow hairs. Head cylindrical, the anterior truncated 

 portion deeply dej^ressed and very closely set with shallow punc- 

 tures ; clypeus medially vertically carinate, the portion of the 

 cheeks forming the lateral rims of the depressed trinication 

 carinate along the edge ; head wider anteriorly than at the 

 occiput, this latter rounded posteriorly. Thorax as in Cstricta^ ; 

 legs short, the femora and tibife compressed, anterior femora 

 remarkably broad. JS'ode of pedicel thick, transA'erse above ; 

 abdomen elongate, massive.

Type, C. ligniperdvs, Latr., from Europe. 



Bange. Both hemispheres. 



^ . Mandibles triangular or subtriangular. with broad toothed 

 masticatory margins ; maxillary palpi 6-, labial palpi 4-jointed ; 

 clypeus trapeziform, not extending to the outer border of the 

 cheeks ; antennal carinse sinuate, somewhat S-shaped, rising from 

 the posterior border of the clypeus ; antennal and clypeal hollows 

 separate ; antennae 12-iointed, filiform, originating remote from 

 the posterior border of the clypeus ; frontal area small, broader 

 than long ; eyes moderately large, placed above the middle line of 

 the head ; ocelli absent. 



Thorax anteriorly broad, posteriorly more or less compressed ; 

 pro-meso- and meso-metanotal sutures generally distinct. The 

 form of the thorax varies much among Indian species of this 

 genus, but four fairly distinct types occur : {a) pro-, meso- and 

 metanotum forming a regular arch ; (h) pro-, meso- and meta- 

 notum forming an arch, but the last more or less truncate at 

 apex ; (c) pro- and mesonotum arched, metanotum gibbous, raised 

 out of the line of the curve ; (d) pro- and mesonotum arched, 

 meso-metanotal suture emarginate, metanotinn very strongly 

 laterally compressed, the sides vertical, the l)asal portion above
