clouded, and abdomen infuscated apically. The thoracic chaetotaxy 

 is the same as in those species, as are also most of the other charac- 

 ters. All frontal bristles long; arista plumose. Fore femoral comb 

 present; njid tibia without posterior bristles and with three long 

 apical ventral bristles. 



Length, 4.5-5 mm. 



I have not seen an undoubted male of gi^ossa^ so am unable to com- 

 pare the hypopygrium with that of fuscohrunnea (Fig. 84). 



Type^ allotype^ and one female paratype., Mount Maquiling, 

 Luzon; female paratypeSj Kolambugan, and Butuan, Mindanao (C. 

 F. Baker) ; male paratype^ Philippine Islands (Osten Sacken col- 

 lection).

HOMONEURA (HOMONEURA) LATICOSTA (Thomson) 



Geomi/za laticosta Thompson, Kongl. Svenska Freg. Eugen. Rosa, Insecta, 

 p. 598, 18G9. . 



This species usually has the wings broadly pale smoky brown on 

 costa, the suffusion extending to, or beyond, third vein, and a similar 

 suffusion over the outer cross vein. Sometimes this costal clouding is 

 almost, or quite, absent, and that over the outer cross vein faint. 

 In doubtful cases the structure of the male hypopygium may be 

 depended upon to distinguish the species (Fig. 89). 



Length, 3 mm. 



I have seen a Javanese specimen, and a series from Kolambugan, 

 Mindanao (C. F. Baker). Doctor Frey records it from many locali- 

 ties in the Philippines and from Ceram, Burn, Malacca, and Java. 



HOMONEURA (HOMONEURA) GEOMYZINA (Frcy) 



Mallochomyza geomyzma Frey, Acta Soc. pro Fauna et Flora Fonnica, vol. 56, 

 No. 8, p. 33, 1927. 



Male. — Shining testaceous 5'ellow, abdomen with a round black 

 spot on each side of sixth tergite, and apparently with a larger spot 

 on each side of fifth tergite also. Wings hyaline, with a faint dark 

 cloud along costa from base to about middle of third section, and 

 four conspicuous fuscous clouds (Fig. 48). Legs yellow, fore tarsi 

 brovv'nish. Halteres yellow. 



Frons wider than long, inner vertical bristle very long, orbitals 

 shorter, but still long and strong, ocellars comparatively short and 

 weak, about half as long as postverticals; third antennal segment 

 about 1.5 as long as wide; arista long plumose; hairs on lower part of 

 sides of face very fine and regular. Thorax with throe pairs of 

 strong postsutural dorsocentrals, the anterior pair at suture, and 

 three pairs of long acrostichals, the anterior pair a little in front of
