XII, D. 2 Muir: Derbidse of the Philippine Islands 85 



waxy secretion at times covers the scutellum and middle line 

 of abdomen. Tegmina hyaline; subcosta, radius, media (but 

 not sectors), and base of cubitus reddish, other veins light 

 brown ; base of cubitus, base of median cell to first sector, radial, 

 subcostal, and costal cells to apex fuscous, the dark color 

 passing over base of second sector to first, and over base of third 

 and fourth sectors and radial apical cross vein, lightly fuscous 

 between veins on apical margin, the apices of veins there being 

 lighter; wings reaching nearly to middle of tegmina, hyaline, 

 with brown veins. 



Ventral edge of pygophor at middle with a subangular process, 

 a little longer than width of base, apex rounded; lateral edges 

 broadly and bluntly angular at sides of anal segment; anal seg- 

 ment extending about a third beyond lateral projections, anus 

 at about middle, in dorsal view sides subparallel or slightly 

 concave, apex broadly rounded; genital styles reaching slightly 

 beyond anal segment, dorsal edge angularly produced before 

 apex, a small, round knob on inner border before middle, ventral 

 edge with a small, curved emargination beyond middle, apex 

 broadly angular. 



Female. — Pregenital sternite subangularly produced from 

 sides to middle; anal segment a little longer than wide, subtur- 

 binate. 



Length, 4 millimeters; tegmen, 9.5. 



Mindanao, Lanao, Kolambugan (Banks), cotype in College of 

 Agriculture, No. 18109, Davao (Baker). 



In coloration this species is like the next preceding, but the 

 short anal segment in the male, with its rounded apex, and the 

 shorter and blunter genital styles distinguish it. The Davao 

 specimens are darker than those from Kolambugan. 



Genus LOSBAnOSIA novum 



Head considerably narrower than thorax; vertex quadrate, 

 apex truncate, narrower than base, disk excavate ; face narrow- 

 ing between eyes, then widening below eyes, again narrowing 

 slightly, then widening; no distinct demarcation between face 

 and clypeus, lateral carinse of vertex continued down face to 

 below antennse ; eyes round, bulging, with exceedingly small an- 

 tennal emargination on ventral edge ; length of clypeus subequal 

 to face, lateral carinse small, median carina distinct, continued 

 onto face for some distance ; antennse cylindrical, as long as head 

 and thorax together; thorax, legs, and abdomen as in Zoraida. 

 Radius arising from subcosta about one fourth from base, sub- 

 costal cell very narrow ; median vein very close to radius as far
