punctures along margin, these more widely placed towards apex; 

 a wide oblique punctate impression on each elytron near base 

 (facing humeral angre); space between this impression and base 

 strongly convex. Ventral segments impunctate. Anterior tro- 

 chanters narrow ; femora strongly dilatate above trochanters, 

 compressed, not channelled on lower side; tibiae wide at apex, 

 external apical projection stout, curved; intermediate tibise lightly 

 incrassate, external angle pointed, not dentate. 



Length 25, breadth 5 -5 mm.

Diflfers from the descrii^tion of T. inacros, Bates, by its smaller 

 size, colour, the clypeus not having four teeth of equal size, &c. 



Teratidium laticeps, n.sp. 



Narrow, elongate, leather depressed, Isevigate; head large, sub- 

 quadrate, constricted posteriorly; elytra impunctate, oboval, lateral 

 borders thick (forming a bead along sides); anterior tibise uniden- 

 tate. Head black with faint purple reflections on occiput and 

 below orbits; prothorax shining purple on disc widely margined 

 with green, under parts tinged with purple and green ; elytra 

 purple; legs, antennae and abdomen black (ventral segments with 

 faint greenish reflections). 



Head large (3-25 x 4-5 mm.), convex ; anterior part widely 

 subquadrate; front with a light (almost obsolete) oblique linear 

 impression on each side defining sides of clypeus and terminating 

 posteriorly in a punctiform impression ; vertex wide, smooth, 

 convex : clypeus convex, roundly and deeply declivous to anterior 

 margin, a light punctiform impression on each side behind inter- 

 mediate angles; median part small, emarginate-truncate; inter- 

 mediate angles very obtuse and hardly prominent; supra-antennal 

 plates large, convex, smooth, not transversely sulcate; eyes deeply 

 set in orbits, depressed ; orbits large, projecting beyond and 

 enclosing the posterior two-thirds of eyes, one supraorbital
