XII, D, 3 Bezzi: Studies in Philippine Diptera, II 117 



Male. — Length of body, 11.5 millimeters; of wing, 14.5. Head 

 and rostrum yellow; palpi and antennse as in L. opaca. Thorax, 

 scutellum, halteres, and abdomen as in L. opaca. Genitalia 

 with yellow, not brown, forceps. Legs wanting in the type. 

 Wings with a strong yellowish tinge and a broad black border, 

 extended from end of first vein to the base of fourth posterior 

 cell; marginal cross vein elongated; discal cell a little shorter 

 than in L. opaca; third posterior cell at base longer than the 

 second, the veins, therefore, not on the same line as in opaca and 

 exactly the opposite of the condition in familiaris. 



Luzon, Laguna, Mount Maquiling (Baker). 



123. Libnotes termitina 0. S. 1882. 



One male from Mount Maquiling. Endemic. 



124. Geranomyia argentifera de Meij. 1911. 



One female from Mount Maquiling. Know only from Java; 

 a very distinct species on account of the hyaline wings and the 

 silvery patches on frons and thorax. 



125. Wallacea argentea Dol. 1858. 



Los Bafios. 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, Hispidse), 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 antennse 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. cxrul- 

 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.^ In the present species 

 both sexes are completely black.
