Scutellum brownish. Halteres pale yellowish. Abdomen black- 

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

 hairs. Coxse and femora pale yellowish; tibise and tarsi pale 

 brownish. 



Wings grayish hyaline, iridescent, with bro\^Ti 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. 



Luzon, Laguna, Mount Maquiling {Baker), one female. 



129. Chrysopilus luctuosus Brun. 1909. 



Male specimens from Mount Maquiling. They agree with 

 the specimens from Formosa, referred by me '' to the present 

 species, described from Assam. 



Of the typical endemic species Chrysopihis correctus, recorded 

 in the first century as No. 12, there are also specimens from 

 Malinao, Tayabas, and from Butuan, Mindanao. The wing pat- 

 tern seems to be variable in shape, remaining, however, of the 

 same type ; in the Butuan specimens the wings have a yellow tint, 

 which is less developed in other specimens. In the undescribed 

 male the thorax and the scutellum are clothed with shining 

 metallic tomentum. The eyes are united, but there is no distinct 

 differentiation between upper and lower areolets, a character 

 somewhat aberrant in ChrysopiliLs. 



130. Chrysopilus diplostigma sp. nov. 



A small black species, distinguished by the peculiar abdominal 

 pattern and by the enlarged stigmatic spot of the wings. 



Male. — Length of body, 5 millimeters; of wing, 5. Head 

 black, dark gray-dusted on occiput and face; eyes bisected, 

 united on a long line; ocellar tubercle very prominent, bare; 

 antennae short, entirely black, with long, rather thick style; 

 facial bulla shining black, ovate, gray on the sides; proboscis 

 and palpi black, the latter black-haired. Thorax velvety black, 

 rather shining, gray-dusted on sides and on the pleurae; a trace
