Genus PROTJTISTA Kirkaldy 



Proutista moesta (Westwood) . 



Derbe (Phenice) moesta Westwood, Ann. & Mag. Nat. Hist. (1851), 



II, 7, 209. 

 Proutista moesta KiRKALDY, Entomologist (1904), 279. 



Common on sugar cane at Los Banos. This is a very common 

 and widely distributed insect, but I have not been able to find 

 the young. 



Luzon, Manila {Banks); Mindoro, Mangarin (Banks). 

 Bureau of Science Nos. 2256, 6499, 17022. 



Proutista nigritarsis sp. nov. 



Male — Labium flattened and w^idened toward the apex. Light 

 brown, clypeus and proboscis dark brown or black, carinse of 

 thorax and legs lighter, apex of tibiae and third tarsal segment 

 black, abdominal segments with darker marks along hind 

 margin. Tegmina very similar to those of P. moesta (West- 

 wood), but with markings browner and not so extensive, 

 especially in the apical median cells. 



Pygophor with ventral edge straight; anal segment long, 

 narrow, subparallel-sided, apical third turned ventrad at a right 

 angle to basal portion, apex rounded; genital styles long, 

 narrow, subparallel-sided, slightly bent a little beyond middle, 

 apex rounded and slightly swollen, forming a small knob; a 

 small, thick spine arises from the dorsal edge near base. 



Length, 2.7 millimeters; tegmen, 6.3, 



Female. — Similar to the male in size and coloring. The small 

 plates at the sides of the genital area larger than in P. moesta 

 and considerably thickened. 



Mindanao, Zamboanga (Baker). 



Genus NEOCAMMA Melichar 



Neocamma trifasciata Melichar. 



Neocamma trifasciata Melichar, Phil. Journ. Sci., Sec. D (1914), 9, 

 435, PI. 1, figs. 1-4. 



I have not seen specimens of this genus, but according to 

 Melichar's figures it differs from allied genera in having the 

 clavus closed, the claval suture and claval vein extending to the 

 hind margin; the subcosta and radius separate near base, but 

 amalgamate again near apex; the neuration of the wing also 

 differs. In coloration this species is similar to Paraproutista 

 trifasciata Muir.
