the first are ver\^ finely hirsute ; pronotum above rugose, not 

 tuberculate, the margins oh" the latei'ai processes more strongly 

 spined than in the preceding species ; scutellum and corium finely 

 pilose ; posterior femora in the male less incrassated than in 

 D. grayi, spined on inner margins and with a series of tubercles 

 above, in female slender and, not spined on inner margin, all the 

 femora in both sexes angulate beneath near apices ; tibice not 

 prominently dilated as in I), r/rai/i.

545. Derepteryx feana, sp. u, 



Piceous, ochraceously pilose, membrane shining, cupreous ; an- 

 tennjie with the first, second, and third joints finely hirsute, the 

 fourth joint a little paler and pilose ; pronotum granulate and 

 rugulose, with a distinct central black carinate line, the lateral 

 processes just passing the apex of the head, their apices broad, 

 obliquely truncate, their margins irregularly serrate, posterior 

 margins more strongly serrate ; abdomen above red, connexivum 

 piceous ; sternum beneath with an ochraceous spot near the 

 odoriferoiis apertures ; posterior femoni distinctly blackly tuber- 

 culate in both sexes ; posterior tibise dilated on both sides, in the 

 male angulate on inner margins. 



Length 31 to 33 ; breadth between pronotal angles, d 16, 5 19 

 millim. 



Hab. Tenasserim : Thagata (Fea). 



A species to be recognized by the broadly oblique apices of the 

 pronotal processes, and by the elongate body.

Type, H. spinosa. Sign. 



Distribution. Eastern Himalayas and Assam. 



Differs from the preceding genus (Derejiteryx) by having the 

 lateral processes of the pronotum more or less horizontally pro- 

 duced and not extending beyond the apex of the head ; the 

 posterior femora in both sexes are somewhat strongly tuberculate, 

 in the male strongly spined beneath before apex ; tibias dilated in 

 both sexes, in the male denticulated on inner margins ; the femora 

 above have on each side near apex a small lobate process ; apex 

 of scutellum tuberculate ; antennae with the basal joint longest ; 

 abdomen unarmed.
