CniOCEPHALUS. 97 



depressed than the rest of its surface ; labrura with three tufts of 

 setpe — oue median near its front margin, the others near the 

 postero-lateral angles ; ej'es witliout long hairs, the upper lobes 

 rather broad, the lower lobes extended to the ventral surface, 

 but widely separated below ; gular area 

 between them slightly convex, trans- 

 versely rugulose and more or less punctate, 

 clothed with long erect hairs. Antennae 

 reach at the seventh joint a little past 

 the middle of the elytra (the joints 

 succeeding the seventh have been lost 

 from the type specimen) ; first joint not 

 attaining to the hind margin of the eye ; 

 the second nearly half as long as the 

 first and more than half the length of 

 -p.^ qc^ the third. Prothorax rather sharply 



Criocephaius'exoticus, rounded at the middle of each side, nar- 

 Sharp. X 5. I'owed towai'ds base and apex, its length 



not quite equal to its width across the 

 middle ; the disc flattened, with a rather deep fovea on each side 

 and an impressed line along the middle, the surface very finely 

 and densely punctulate. Elytra very faintly pnnctulate, each 

 with t\AO feeble dorsal costse and a very short lateral one. Pro- 

 sternum slightly convex and somewhat rugulose in front ; its 

 intercoxal process narrow and laminiform. Cleft of the third 

 tarsal joint extends about halfway to the base in the anterior 

 tarsi and one-third of the way in the liiud tarsi ; first joint of the 

 hind tarsi nearly as long as the remaining joints united. 

 Length 11 ; hreadth z> vaiw.

90. Criocephalus unicolor, sp. u. 



Perruginous. Head ^\'ith the clypeo-frontal sutures very 

 distinct, meeting at a sharp angle in the middle ; eyes narrower 

 than in C. exoticus. Sharp, the lower lobes reach to the ventral 

 surface but remain \\idely separated below ; the gular area 

 between them convexly swollen, strongly rugose-punctate, and 

 in the S wdth a shght transversely elliptical depression, which 

 is clothed, but not very densely, with longish hairs ; palpi very 

 short, the last joint moderately dilated. Antennte a little longer 

 than the body in the 6 , reaching to the posterior third of the 

 elytra in the $ ; first joint short but extended to the hind margin 

 of the eye, second about two-thirds the length of the first and one- 

 third the length of the third. Prothoi'ax slightly rounded at the 

 sides, its length in the c? fi trifle greater than its width across the 

 middle, and in the $ a little less ; convex above, but with a broad, 

 shallow, median depression followed near the base by a feeble 

 tubercular elevation ; the surface densely punctate and sparsely 

 but very distinctly asperate. Elytra densely and rather strongly
