24 PHILIPPINE DIPTERA, II 



described by Wiedemann. I refer them provisionally to the 

 present species because of the great variability attributed to it. 8 



138. Epholchiolaphria leucoprocta Wied. 1828. 



Los Bafios and Mount Maquiling, Luzon. Even in these speci- 

 mens the mystax is yellow instead of black. The present species 

 is considered by Hermann to be only a form of E. vulcanus. 

 But these Philippine specimens are well distinguished by the 

 scutellum and the two basal abdominal segments being clothed 

 with argenteous hairs, which in the female are of a golden color ; 

 on the second segment these hairs are present only at sides and 

 at hind border. 



139. Epholchiolaphria partialis nom. nov. (partita Walker, 1860, 



not of same author, 1857, Borneo) . 



Numerous specimens from Mount Maquiling, Laguna, and 

 Malinao, Tayabas, Luzon; and from Cagayan, Mindanao. De- 

 scribed from Celebes, but recorded from the Philippines by 

 Osten Sacken. It is very closely allied to Laphria dimidiata 

 Macquart, No. 13 of the first "century," which belongs also to 

 Epholchiolaphria Hermann, and of which there are also numerous 

 other specimens from Mount Maquiling, Laguna, and Malinao, 

 Tayabas, Luzon; and from Dapitan and Butuan, Mindanao. 



140. Epholchiolaphria aurifacies Macq. 1848. 



Los Banos. Widely spread over the Malay Archipelago and 

 usually referred to the genus Maira. These specimens answer 

 also to the description of azurea Hermann, 1914, from Formosa. 



141. Smeringolaphria alternans Wied. 1828. 



Dapitan, Mindanao. Widely spread over the Oriental Region 

 and recorded also from Formosa. 



142. Anisosis phalaris 0. S. 1882. 



Mount Maquiling, Luzon. A very characteristic, endemic 

 species. The name Anisosis Hermann, 1914, is preoccupied by 

 Anisosis Deyrolle, 1857, in the Coleoptera. 



143. Orthogonis scapularis Wied. 1828. 



Mount Maquiling, Luzon. Widely spread over the Asiatic 

 Archipelago to New Guinea. 



144. Pogonosoma cyanogaster sp. nov. 



This new species is closely allied to P. bleekeri Doleschall from 

 Amboina and to P. semifuscum van der Wulp from Batjan, but
