vein ; veins light with large brown granules ; hind wings fuscous 

 with dark veins. 



Pygophor about as deep as wide, a pair of very small, flat- 

 tened spines on the medioventral edge ; anal spines large, slightly 

 flattened, diverging and slightly curved ; styles broadest at base, 

 narrowing to apex where they are produced into small bifurca- 

 tions. 



Length, 2.7 millimeters; tegmen, 4.2. 



Female. — Unknown. 



Mindanao, Davao (Baker). 



This is a Philippine representative of the Australian P. gra- 

 minicida Kirkaldy; there is little difference in the genitalia, but 

 the concolorous face and the greater expanse of the fuscous area 

 on the tegmina distinguish it. 



Perkinsiella pseudosinensis sp. nov. 



Male. — Face between eyes, clypeus, front coxae, pleura, and 

 abdomen dark brown; face beyond eyes, gense, antennse, and 

 legs yellow or light brown; apex of first joint and sense organs 

 of second joint of antennse dark; vertex and nota brown with 

 lighter carinse. Tegmina hyaline, veins light, granules brown, 

 a fuscous spot at end of claval vein fuscous from cross veins over 

 sixth and in apical portion of sixth and seventh apical cells; 

 wings hyaline, veins brown. 



Medioventral spines of pygophor flattened, broad, cultrate in 

 outline, and spines subulate, slightly diverging and curved, gen- 

 ital styles quadrate at base, the outer, upper corner produced and 

 continued in a bifurcate process, the inner furcation flattened, 

 curved into a semicircle, apex rounded, the outer furcation short, 

 flattened, curved, the two together forming three fourths of a 

 circle. 



Length, 2.5 millimeters; tegmen, 3.7. 



Female. — Similar to the male. 



Length, 3 millimeters ; tegmen, 4. 



Mindanao, Davao, Digan (Baker). 



This species is superficially very similar to P. sinensis 

 Kirkaldy, but the genitalia are very different.
