J.RT. 6 NOTES ON ORIENTAL SAPROMYZID FLIES MALLOCH 27 



S. Basal portion of male hn^'pysiuni (eighth tergite) with the apical lateral 

 arms hinged and furcate, or with internal tooth (Fig. 26). 



luteitarsis (de Meijere). 



Basal portion of male hypopygium with the apical lateral arms connected 



with the basal part by a narrow neck, not hinged to it, and sharp at apex 



(Fig. 27) philippinensis, new species. 



MiNETTiELLA, new subgenus 



This subgenus is erected for the reception of two species, both of 

 which are glossy black, with immaculate wings, yellow halteres, and 

 characters as given in key. 



Suhgenotype. — Lauxania atratvla de Meijere. 



Neither species is amongst those before me from the Philippines, 

 though it is very probable that one or both may occur there. 



Subgenus Minettia Robineau-Desvoidy 



In his paper on Philippine Sapromyzidae Doctor Frey gives the sub- 

 generic name Euminettia to the segregate of Minettia in which there 

 are no elevations on the face, naming lupuUna Fabricius as genotype. 

 I rather doubt the possibility of distinguishing the segregates by this 

 character, as the elevations, while quite noticeable in some species, are 

 very inconspicuous in others and it is very difficult, if not impossible, 

 to draw the line anywhere. The same author erects the subgenus 

 Calominettia for the South American species geminata Fabricius. 

 The latter he distinguished from Euminettia by the divergent apical 

 soutellar bristles, a rather variable character. 



There are but two species of those listed in the key amongst those 

 before me from the Philippines, though undoubtedly more occur there. 



MINETTIA RUFIVENTRIS (Macquart) 



Minettia rufiventris Macquart Dipt. Exot. SuiJpl. 3, p. 68, 1847. 



This species appears to be very widely distributed in the Orient, 

 occurring in Formosa, the Nederland Indies, etc. I have before me 

 one specimen from Imugin, N. Viscaya (C. F. Baker), and Frey 

 records it from Luzon. 



MINETTIA PHILIPPINENSIS, new species 



Male and female. — Similar to luteitarsis (de Meijere) in coloration. 

 Black, the face and fi-ons whitish dusted, the former most densely so ; 

 thorax with brownish dust and four faint vittae on dorsum ; abdomen 

 shining, without dusting; wings yellowish hyaline, almost honey 

 yellow; halteres honey yellow. The legs are pitchy black, with the 

 bases of tibiae slightly yellowish and the tarsi yellow. 



Structurally similar to luteitarsis, the frontal bristles all strong, 

 arista with long hairs; thorax with three pairs of dorsocentrals, tlie
