HOMONEURA (HOMONEURA) CIRCUMCINCTA (Frey) 



MalloGhom'jza circumcineta Fket, Acta Soc. pro Fauna et Flora Fennica, vol. 

 56, No. 8, p. 39. 



Female. — Head yellowish testaceous, frons more ochreous, the or- 

 bital stripes and ocellar spot gray; basal two antennal segments and 

 base of third up to insertion of arista, deep black, third segment 

 darkened at apex; aristae and their hairs black; palpi yellow. 

 Thorax fuscous, densely gray dusted, humeral angles, most of pleura, 

 notopleural suture, a narrow apical margin of scutellum and ventral 

 surface of same, testaceous yellow. Abdomen fuscous, densely gray 

 dusted, apices of tergites very narrowly yellowish, their lateral mar- 

 gins more broadly so. Legs testaceous yellow, or stramineous, with 

 a faint dark mark on anterior surface of fore femur at the preapical 

 comb. Wings hyaline. Halteres pale. 



Anterior orbital strong, farther from eye than posterior; ©cellars 

 as long as postverticals ; arista plumose; third antennal segment 

 about 1.5 as long as wide; face slightly convex. Thorax normal, 

 with three pairs of postsutural dorsocentrals ; scutellum flat above. 

 Fore femur with anteroventral comb ; fore tibia with short preapical 

 dorsal bristle; mid tibia with one long and two, unequal, shorter, 

 apical ventral bristles. Inner cross vein close to middle of discal 

 cell ; penultimate section of fourth vein about half as long as ultimate 

 section. 



Length, 4 mm. 



Originally described from Surigao and Mumungan, Mindanao. I 

 have three specimens from Tangcolan, Bukidnon (C. F. Baker). 



HOMONEURA (HOMONEURA) TRIFASCIATA (de Meijere) 



Lauxania trifasciafa de Meijere, Tijdschr. v. Ent., vol. 53, p. 130, 1910. 



A rather robust species, readily distinguished by the very short- 

 haired arista, markings of abdomen, short and weak ocellar bristles, 

 and unclouded cross veins. The hairs on sides of face are short and 

 weak, and the last section of fourth vein is twice as long as preceding 

 section. 



Length, 3.75 mm. 



I have seen this species only from Java. 



HOMONEURA (HOMONEURA) NEOSIGNATA, new species 



Male. — Testeceous yellow. Frons dull except the orbits and tri- 

 angle, ocellar region not darkened, face glossy, parafacials dull, white 

 dusted, antennae and palpi yellow. Thorax unicolorous yellow, 

 glossy. Abdomen not so glossy as mesonotum, with a large round 

 black spot on each side of fourth visible tergite. Legs yellow. 

 Wings yellowish hyaline, outer cross vein with a very slight indication 

 of a yellowish cloud. Halteres yellow.
