Lamenia pMlippina sp. nov. 



Male. — Dark shining brown, lighter over legs and ventral sur- 

 face. Tegmina dark shining brown with a small light dot at 

 the apex of costal cell. 



Ventral edge of pygophor straight, lateral edges slightly 

 rounded ; anal segment long and narrow, length nearly four times 

 the width, anus about one third from base, sides subparallel on 

 basal half, gradually converging to apex, which is curved ven- 

 trad; a deep, narrow cleft from apex halfway to anus; genital 

 styles long and narrow, the apices acute and curved upward; a 

 sharp spine arises from the inner surface near base. 



Length, 2.7 millimeters; tegmen, 4. 



Female unknown.

Placed by its author with Nisia, in the Achilinae. Specimens 

 from the type locality that I identify as this species have the 

 following genital characters: 



Male. — Ventral edge of pygophor straight, lateral edges an- 

 gularly produced; length of anal segment a little more than 

 twice the width, anus in middle, sides parallel to middle, then 

 gradually converging to the bluntly pointed apex; genital style 

 long and narrow, slightly constricted just before the subtrun- 

 cate apex; otherwise the edges subparallel, a quadrate process 

 wider than high arises from the inner surface near base. 



Female. — The posterior edge of the pregenital sternite slightly 

 produced on lateral third, but steeply so on the median third, 

 the production longer than broad at base, with rounded apex; 

 sternite, including the production, longer than broad. 



Mindanao, Davao [Baker), one male, which agrees with the 

 Maquiling specimens; Laguna, Los Baiios (Banks), College of 

 Agriculture, No. 18116. 



Lamenia pseudotypicus (Muir). 



Thyrocephalus pseudotypicus MuiR, Bull. Hawaiian Sugar Plant.

Two specimens from Mindanao — one from Davao and the 

 other from Zamboanga (Baker) — appear to be this species, pre- 

 viously known from Borneo.
