PHILIPPINE DIPTERA, II 17 



125. WaUacea argentea Dol. 1858. 



Los Banos. A well-known species, widely distributed over 

 the Oriental Region to New Guinea. 



In case the generic name Wallacea Doleschall, 1858, is pre- 

 occupied by Wallacea Baly, 1858 (Coleoptera, Hispidae), the 

 name Gabaza Walker, 1859, must be employed in its place. 



126. Atherix limbata 0. S. 1882. 



Mount Maquiling. The undescribed male of this endemic 

 species is very much like the female; the eyes are united for a 

 long distance ; the antennae and the proboscis are lighter yellow ; 

 the palpi are yellow and clothed with a shining white dust. The 

 coloration of the abdomen is exactly the same as in the female ; 

 the entire last segment and the sides of the penultimate seg- 

 ment are reddish; genitalia erected, pale yellowish, whitish at 

 end. Legs and wings as in the female. 



127. Atherix fascipennis sp. nov. 



The present species belongs to the oriental group of species 

 distinguished by the body being wholly black, at least in the 

 female, like A. cincta Brunetti, A. lucens de Meijere, A. cserul- 

 escens Brunetti, but it is possible that some unknown males of 

 these species have a partly yellow abdomen, as described by me 

 for the Formosan specimens of A. cincta. 5 In the present species 

 both sexes are completely black. 



Male and female. Length of body, 10 millimeters in the male 

 and 11 to 12 in the female; of wing, 8 in the male and 9.5 to 10.5 

 in the female. Head black, with gray dust on the occiput; eyes 

 of the male united for a line shorter than in A. limbata; the frons 

 in the male white-dusted above the antennae and deep black on 

 fore half, in the female narrow, gray-dusted at vertex to the 

 ocelli, deep black on middle, white-dusted above the antennae. 

 Face white-dusted in both sexes, with the middle bulla more 

 developed and more prominent in the female than in the male. 

 Antennae entirely black, with long, thin black arista; palpi 

 black, white-dusted and black-haired; proboscis wholly black. 

 Hairs of the head black on frons and vertex, white on the occiput 

 and below. 



Thorax entirely black, even on the humeral calli, in the male 

 more intensively black and more shining than in female ; pleurae 

 clothed with shining gray dust and with whitish hairs ; the hairs 

 on the dorsum entirely black in the male, whitish on the hind 

 half in female; above the humeri there is inward a narrow
