PHILIPPINE DIPTERA, II 21 



base; second posterior cell acute at base and longer than the 

 third; the last shorter than the discoidal cell. Squamae pellucid 

 brown, with pale fringe. 



LUZON, Laguna, Los Bafios (Baker). 



131. Mydas fruhstorferi van der Wulp. 1896. 



Mount Maquiling. Two female specimens, which answer 

 perfectly to the description of the species from Java. Species 

 of the present genus seem to be very scarce in the Oriental 

 Region, only two others being known: namely, one from India 

 (ruficornis Wiedemann) and one from Celebes and Sumatra 

 (basifascia Walker) ; but I have in my collection a species from 

 Ceylon that differs from all the others in being entirely black 

 with the last three abdominal segments wholly rufous. 



132. Leptogaster princeps O. S. 1882. 



Specimens from Mount Banahao. A very distinct, endemic 

 species, which may be considered as gigantic in its genus. 



133. Saropogon mbricosus sp. nov. 



Very near S. jucundus van der Wulp, 1872 (vertebratus Bigot, 

 1878), from Java and Sumatra, but distinguished by the wholly 

 rufous abdomen and hind legs. The apical spur of the front 

 tibiae is very small and easily overlooked; thus van der Wulp 

 has described this species as belonging to Habropogon, and Bigot 

 placed it in Scylaticus, a fact recently noted by de Meijere, who 

 has described another allied species from Java. 



Female. Length of body, 11 millimeters; of wing, 10. Head 

 black, with pale reddish face; the occiput clothed with dense 

 whitish dust near the eyes; frons shining on the middle and 

 white at the eye borders; face clothed with dense whitish dust 

 with a yellowish sheen. Antennae entirely black, the first two 

 joints with black hairs, the third linear, longer than the first 

 two together. Mystax formed by only four pale yellowish 

 bristles; proboscis and palpi black, the latter with yellowish 

 hairs, ocellar bristles black. Thorax and scutellum entirely shin- 

 ing reddish, only the humeral calli with a broad shining black 

 spot; collar with yellowish bristles and a brown spot on each 

 side; macrochaetae black, those of the dorsocentral rows rather 

 long and much produced over the suture; pleurae with scanty 

 yellowish tomentum; metapleura with yellow bristles. Scutel- 

 lum with two strong black apical macrochaetae ; mesophragma 

 reddish, gray-dusted. Halteres yellowish. 



Abdomen cylindric, of the same color as the thorax, shining
