XII, D, 2 Muir: Derbidse of the Philippine Islands 59 



The genitalia differ from those of P. badia in having the 

 medioventral process more acute; the anal segment wider, with 

 the apical emargination slightly wider; the quadrate process on 

 dorsal edge of genital style more rounded; and the apex shorter 

 and blunter. 



Length, 4 millimeters; tegmen, 6.

 Wurmb. 



This species, like P. badia, is often covered with a white waxy 

 secretion. 



Genus SYNTAMES Fowler 



Syntames tubulifer Melichar. 



Syntames tuhulifer Melichar, Phil. Journ. Sci., Sec. D (1914), 9, 269. 

 I consider that this species represents a new genus of Cixiidse; 

 the neuration is not that of Syntames, and the long apical joint 

 of the labium excludes it from the Derbidae. The peculiar ab- 

 dominal structures are somewhat allied to those of Benna and 

 Bennaria. 



Genus HERPIS Stal 



Herpis flavescens sp. nov. 



Congeneric with H. vulgaris (Fitch) ; subcosta and radius

 of abdomen darker. Tegmina yellow or fuscous yellow, veins

Pygophor short, ventral and lateral edges straight; anal seg- 

 ment considerably longer than wide, gradually narrowing to 

 near middle, then subparallel-sided to apex, which is obtusely 

 pointed, a small dorsal ridge near the middle of base, anal style 

 at apex on ventral surface; genital styles large, subquadrate, 

 narrowest at base, widest at apex, on apical edge two small, 

 angular projections turned inward.

 terior edge angularly produced.
