mesonotum, but with a black longitudinal stripe on each side 

 not reaching the hind border, and thus forming the three lon- 

 gitudinal yellow stripes, the middle of which is exactly in contin- 

 uation of that of scutellum and mesonotum; venter yellow and 

 brown, rather shining. Male genitalia black, rounded, retracted, 

 with some short black and red appendages below and with a 

 very long, spiral, shining reddish penis ; ovipositor short, black, 

 flattened. Legs yellow, with yellow pubescence; front coxse 

 mainly black ; femora and tibise broadly black at end, sometimes 

 the anterior femora and even the middle ones entirely black 

 with yellow ends ; basal joint of all the tarsi whitish. 



Wings with a distinct yellowish tinge at base and fore border ; 

 covered with numerous dark spots, which are in part confluent, 

 but without forming distinct crossbands; hind cross vein with 

 a broad fuscous border, and in continuation with it a subobsolete 

 band, interrupted by hyaline spots, which ends at apex of the 

 first longitudinal vein. Third and fourth longitudinal veins 

 entirely straight and parallel in their last sections; anterior 

 cross vein oblique and placed near the middle of the very long 

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

 terminated by a straight cross vein. 



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
