54 PHILIPPINE DIPTERA, II 



continued above on the dorsum along the suture in the shape 

 of a whitish triangle. Scutellum black, with yellow pubescence 

 and with a spot of whitish dust on each side at apex, which is 

 convex, not emarginate ; two pairs of strong black apical bristles. 

 Squamae whitish; halteres yellowish. Abdomen black, gray- 

 dusted; the last three segments provided w r ith scattered, broad 

 whitish scales. Venter and genitalia black. Legs deep black, 

 with black pubescence, front coxse gray-dusted and white-pubes- 

 cent anteriorly; basal joint of all the tarsi whitish. 



Wings not yellow at base, the fuscous pattern about as in 

 Renders Plate II, fig. 39; a dimidiate band before the middle 

 band; the third band prolonged to the hind border, the apex 

 of wing appearing entirely fuscous, with two hyaline spots.

194. Euprosopia longicornis sp. nov. 



Closely allied to E. lepidophora, but smaller and differently 

 colored. 



Male and female. Length of body, 5 to 5.5 millimeters; of 

 wing, 5 to 5.5. Head exactly as in E. lepidophora, but the 

 antennae entirely black, a little dark brownish near the base ; the 

 third antennal joint longer, being a little longer than the face; 

 the broad facial triangle more yellowish than white and destitute 

 of red stripes; epistome without black band; the genal bristle 

 much weaker. 



Mesonotum and abdomen entirely as in E. lepidophora, ovi- 

 positor short, broad, flattened, black. Legs with the four pos- 

 terior tibiae broadly yellowish on the basal half; hind femora 

 with long and dense whitish hairs below. 



Wings as in E. lepidophora, but the pattern less dark; the 

 hyaline space between the second and third bands has above near 

 the fore border a fuscous triangular spot, prolonged to the 

 second longitudinal vein, which is entirely wanting in lepido- 

 phora and in fusifacies; the praeapical band is likewise complete, 

 but there is no dark spot in the hyaline hind border of the 

 second posterior cell.

195. Taeniaptera nigripes van der Wulp. 1881. 



Los Banos, Mount Maquiling, Luzon. Philippine specimens 

 like the present ones have been referred by Osten Sacken.to 

 this species described from Sumatra, but I think it probable that 

 they belong to an undescribed species; the rings on femora are 

 white, not reddish as in typical specimens.
