two contiguous ivory-white spots at the base and two similar spots 

 just past the middle, these spots larger and broader than the 

 corresponding spots in G. eburifira, Thorns., but very like those 

 that occur in the Malayan species G. subnuda, Lac. Head im- 

 pressed with a deep arcuate groove between the clypeus and front 

 as in the other species of the genus ; the mandibles strong, but 

 oblique as in the c? and with only a dorsal carina gradually 

 sloping away in front, instead of the strong, anteriorly projecting 

 crest met with in the other species. Antenna? of the <3 rather 

 more than one-third longer than the body, furnished sparsely with 

 longish hail's ; first joint obconical, not very stout, distinctly but 

 not very thickly punctured and scarcely impressed in front ; this 

 and the two or three succeeding joints rather glossy, the others 

 duller. Prothorax minutely and rather sparsely granulate, sparsely 

 pubescent, and without tubercles on the disc. Elytra sub-rugulose 

 punctate, sparsely clothed with short pubescence, with which some 

 longer sub-erect hairs are mixed ; each rounded at the apex and 

 armed with a sutural spine. 



Length 25 ; breadth 7 mm. 



Sab. Tenasserim : Tavoy (DoJierty).

Type, H. sericeus, Fab., a species found in Southern Europe and 

 North Africa. 



Range. Mediterranean Subregion ; Tenasserim ? ; and West 

 Africa. 



Head feebly raised, slightly concave between the antenna?, the 

 antennal supports not prominent, front subvertical ; gula with 

 a very short, broad mentigerous process. Antenna? longer to a 

 greater or less extent than the body in the tf , shorter than the 

 body in the $ ; first joint gradually thickened to the apex, the 

 others subcylindrical or slightly compressed, eleventh slightly 

 longer than the tenth in the d Prothorax slightly transverse, 

 convex above, rounded at the sides and narrowed more towards 

 the base than in front. Elytra either parallel-sided or nearly so for 

 four-fifths of their length, rounded at the apex. Legs moderately 

 long ; the femora gradually thickened from the base for two-thirds 

 or three-fourths of their length, the hind pair not reaching to the 

 apex of the elytra ; first joint of the hind tarsi not longer than 

 the next two united. Intercoxal process of prosternum slightly 

 arched, sloping gradually posteriorly, usually a little widened 

 towards the end. 



. The species of this genus are in general form very like those of 

 Stromatium, and are distinguishable from them by the less pro- 

 minent antennal supports and the form of the intercoxal process 

 of the prosternum. In the males the prothorax is usually larger 

 and more convex than in the females, but it never has the large
