PHILIPPINE DIPTERA, II 49 



Key to the Philippine species of the genus Euprosopia Macquart (including 

 Notopsila Osten Sacken). 



The present genus also seems to be productive of endemic 

 species in the Philippines. No one of the five species found by 

 Professor Baker can be identified with any of the thirty-three 

 species already known from the Oriental and Australian Re- 

 gions: the group of the species with elongated antennae (lepi- 

 dophora, longicornis) seems to be peculiar to the Islands. The 

 two species, sexpunctata and curta, described by Osten Sacken 

 under the generic name of Notopsila, also belong here, but are 

 wanting in the present collection ; Euprosopia curta was recently 

 recorded from Formosa by Hendel. 



a 1 . Scutellum emarginate, that is, distinctly hollowed at apex; arista bare; 

 wings spotted. 



fe 1 . Face with six deep black spots sexpunctata O. S. 



6 2 . Face without black spots curta O. S. 



a 2 . Scutellum not emarginate, convex at apex; arista shortly plumose; 



wings usually banded. 

 c 1 . Antennae much shorter than the face, as usual. 



d\ Mesonotum adorned with three broad longitudinal bands of 

 yellowish tomentum, the middle of which is continued on scutel- 

 lum and abdomen; front tarsi with yellow bases; wings distinctly 



yellowish, with fuscous spots trivittata sp. nov. 



cP. Mesonotum and abdomen altogether black, without such stripes; 



front tarsi black; wings not yellowish and distinctly banded. 

 e 1 . Much larger; abdomen without white scales; front tarsi much 

 dilated; wings with the second and third bands united with 

 the broad fuscous border of the hind cross vein. 



gigas sp. nov. 



e 2 . Much smaller; abdomen with scattered white scales; front tarsi 

 not dilated; wings with only a single distinct band between 



the numerous dark spots....: millepunctata sp. nov. 



c 2 . Antennae as long as the face, or even a little longer; abdomen with 



scattered white scales; wings conspicuously banded. 

 f 1 . Antennae red; femora and tibiae entirely and intensively black. 



lepidophora sp. nov. 



f. Antennae black; femora and tibiae in part reddish brown or 

 yellowish longicornis sp. nov. 



190. Euprosopia trivittata sp. nov. 



A very distinct species, suggesting Plagiostenopterina trivit- 

 tata Walker by its coloration and seeming to be alljed to E. 

 tigrina Osten Sacken, from New Guinea, which, however, has a 

 very different wing pattern and has no inner frontoorbital 

 bristles. 



Male and female. Length of body, 5 to 6 millimeters; of 

 wings, 5 to 6. Head oval, much higher than broad, entirely
