PHILIPPINE DIPTERA, II 19 



bulla greatly developed and produced below, palpi small; pro- 

 boscis with the terminal flaps much dilated, forming a sort of 

 blister as great as the facial one, minutely transversely rugulose. 

 Antennae with the two basal joints small and short; third joint 

 enormously developed, longer than the breadth of head, and di- 

 vided into two branches from the root; the upper branch is 

 a little shorter, but not narrower than the inferior one, which 

 bears at its end a short, almost rudimentary style (Plate I, fig. 1) . 

 Eyes of the female without a trace of division; male unknown. 

 Thorax, abdomen, and legs as in Chrysopilus ; hind tibiae with 

 a single spur at end, the external one. Wings with the venation 

 exactly as in Chrysopilm; anal cell closed and provided with a 

 short stalk. 



Type, Schizella furcicornis sp. nov. 



128. Schizella furcicornis sp. nov. Plate I, fig. 1. 



A small dark reddish and brown species with pale legs and 

 grayish wings, which are a little spotted toward the middle. 



Female. Length of body, 5 millimeters; of wing, 4.7; of an- 

 tennae, 1.2. Head black, gray-dusted on the occiput and on the 

 sides of the frons; facial bulla pale yellowish, white-dusted; 

 palpi blackish; proboscis with whitish flaps; antennae with the 

 two basal joints yellowish, the third brownish. Thorax dark 

 reddish brown, the pleurae paler and clothed with whitish dust; 

 it is entirely bare, even on metapleura, but it seems that on the 

 hind part there is a short pubescence, with metallic reflections. 

 Scutellum brownish. Halteres pale yellowish. Abdomen black- 

 ish, rather shining, unicolorous, with short and few black 

 hairs. Coxae and femora pale yellowish; tibiae and tarsi pale 

 brownish. 



Wings grayish hyaline, iridescent, with brown veins; stigma 

 of greater size, dark brown, filling up completely the end of the 

 marginal cell. Below the stigma a short dark band, ending 

 on base of the cubital fork; below this band a small dark spot 

 at end of the discoidal cell ; besides, the apex of wings is broadly 

 but faintly infuscated. Cubital fork very long and narrow, 

 gradually broadened toward the end, its upper branch being 

 bent at right angles at base and there provided with a short 

 stump. Second posterior cell acute at base, narrow, and short, 

 not broader and distinctly shorter than the third posterior 

 cell; anterior cross vein short, placed near the base of the dis- 

 coidal cell.
