the first near base, the second below the stigma and crossing the 

 discoidal cell, the third extending from apex of the marginal cell 

 to the middle of the second posterior cell; the hind cross vein 

 margined with fuscous only below and not included in a band, 

 but above it from costa to a little before the fourth vein there 

 is a dimidiate crossband in the hyaline space between the 

 second and third crossbands; in the apical hyaline space some( 

 fuscous spots, forming one or two irregular crossbands. Veins 

 yellowish brown, directed as in P. luteipennis, but the second 

 longitudinal vein distinctly a little wavy, not straight ; anal cross 

 vein distinctly longer than that at end of the second basal cell.

Key to the Philippine species of the genus Euprosopia Macqiiart {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 antennas (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\ Scutellum emai-ginate, that is, distinctly hollowed at apex; arista bare; 

 wings spotted. 



b^. Face with six deep black spots sexpunctata 0. S. 



b^. Face without black spots curta O. S. 



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

 wings usually banded. 

 c\ Antennse 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\ 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'. Much smaller; abdomen with scattered white scales; front tarsi 



not dilated; wings with only a single distinct band between 



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



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

 scattered white scales; wings conspicuously banded.
