380 The Philippine Journal of Science i9i5 



Evidently the commonest of the Philippine species of this 

 genus. Walker, Stal, and Distant have all recorded it from the 

 Islands, and Professor Baker has sent me specimens collected 

 at Los Baiios. 



Black; coarsely and deeply punctate; scutellum and sides of 

 meso- and metathorax densely white tomentose ; metopidium and 

 lateral areas of pronotum covered with long yellowish pubes- 

 cence. Head broader than long, densely pilose, finely punctate; 

 clypeus trilobed, longer than wide ; eyes prominent, light brown ; 

 ocelli translucent, equidistant from each other and from the 

 eyes, and situated on a line passing through center of eyes. 

 Disk of pronotum thick, heavy, and cylindrical; suprahumeral 

 horns flattened, front margin subf oliaceous, tips suddenly acute ; 

 these horns extending outward and backward, almost horizontal, 

 not rising above highest point of posterior process. Posterior 

 process arising from top of posterior region of pronotal disk, 

 gradually sloping downward but not touching tegmina; slender, 

 almost uniform in thickness, triquetrous, tip gradually acumi- 

 nate. Tegmina hyaline with broad, well-defined brown veins; 

 base very slightly punctate and somewhat pilose. White tomen- 

 tose metathorax usually showing through base of wings. Un- 

 dersurface of body, legs, and feet black. 



Length, 8 mm. ; width between extremities of pronotal horns, 

 6.5 to 7 mm. 



Tenasserim, North Bengal (Walker) ; Sumatra (Distant) ; 

 Philippine Islands (Walker, Stal, Distant) ; Luzon, Los Banos 

 {Baker) . 



Leptocentrus adimcus Buckt. 



Leptocentrus aduncus Buckt., Mon. Memb. (1903), 236, PI. 53, fig. 6. 



This species has not been recorded since Buckton's original 

 description, and it seems doubtful if it can be recognized from 

 his short description and poor figure. It apparently may be 

 distinguished only by the short horns and the short and auricu- 

 late posterior process as represented in his plate. Buckton's 

 description follows: 



Dark fuscous, shining and punctured. Suprahumerals short and auri- 

 culate. Posterior horn stout at base and short. Tegmina fuscous. Frons 

 hairy. Size 6x5 mm. Habitat-Luzon, Philippine Isles. 



Genus EMPHUSIS Buckton 



Centrotus Fabr. (in part); Centrotypus StAl (in part). 



The genus Emphusis is peculiar in having been apparently 

 incorrectly diagnosed by its author. Buckton states in his
