but without forming distinct crossbands; hind cross vein with

 first longitudinal vein. Third and fourth longitudinal veins

 discoidal cell; second basal cell longer than the anal, which is

LUZON, Tayabas, Mount Banahao (Baker) . 



191. Euprosopia gigas sp. nov. 



In wing pattern very similar to E. impingens Walker, from 

 New Guinea, but distinguished by its different coloration and by 

 the presence of two pairs of vertical bristles. 



Female. Length of body, 12 millimeters ; of wing, 12. Head 

 higher than broad, with the frons and the face much produced 

 over the eyes, but perhaps only because of an accidental com- 

 pression of the type specimen. Occiput hollowed, yellowish, with 

 two black stripes; frons narrower than an eye, about twice as 

 long as broad, hollowed in the basal half and there yellowish 

 red, prominent in the apical part and there black, with narrow 

 yellowish sides; bristles black, the inner vertical pair only one 

 half as long as the external pair; lunula dark brown; face pale 

 yellow, with a black stripe on each side along the antennal 

 grooves, which is continued below to the mouth borders, but 

 becomes brownish in this part; cheeks black and brown, a little 

 narrower than the third antennal joint; jowls brown, one fifth 

 of eye in breadth. Antennae black, the basal joint a little reddish 

 outward, not longer than one half of face, with a long arista, 

 which is shortly plumose at base, the feathers being as broad 

 as the third joint. Praelabrum narrow, subquadrate, shining 

 yellowish ; palpi less dilated, entirely black, with long black hairs ; 

 proboscis dirty yellowish. 



Mesonotum dull black, densely punctulate, with short and 

 thick black hairs, only in front of the scutellum with yellow hairs ; 

 bristles black, two or three anterior supra-alars; pleurae black, 

 gray-dusted and with numerous rounded black points, with long 

 yellow hairs and some shorter black hairs on anterior part of 

 mesopleura, sternopleura, and pteropleura. Scutellum flattened 

 above, convex behind, reddish brown, darker at base, entirely 

 clothed with shining yellow hairs, which are longer near the 

 borders, and with three pairs of strong black apical bristles, 

 the smaller, external pair being placed most distant from the 

 border. Mesophragma black, smooth, rather shining; squamae
