Metommatius, new subgenus 



Type of subgenus: Om/matius aegyptius Efflatoun, 

 1934. 



In erecting the genus Omm/itinus, Becker (1925), 

 apparently went under the supposition that Asilus chi- 

 nensis Fabricius (1794) was the type of genus of <9m- 

 ma^!^■w5 Wiedemann ; whereas, Coquillett (1910) desig- 

 nated Asilus marginellus Fabricius (1781), a West In- 

 dian species, as the type of genus of Ommatius. This 

 species Ommatius marginellus has the plumes of the 

 artista in two ranks, thus invalidating Ommatinus 

 Becker, which was foimded on Ommatius pinguis Wulp. 

 Apparently, a few species of Ommatius have the plumes 

 in one rank ; all American and Australian species wliich 

 I have seen have the plumes in two well formed ranks. 

 I propose the subgeneric name Metommatius for species 

 with plumes in one rank. The extent of the face in 

 Ommatius seems to be highly variable and to have little 

 of value for purposes of differentiation. 



Genus Merodontina Enderlein 



Merodontina Enderlein, Zool. Anzeiger, vol. 44, p. 262, 1914. 

 Type of genus: Merodontina sikkimensis Enderlein, 1914, 

 by original designation. 



The following is Enderlein's description in translation : 

 Male. Genus of the Asilinae. Antennal bristle (style) long 

 plumose. Hind femur somewhat thickened and below near the 

 base with a strong, rounded tooth. Third antennal segment as 

 long as both the basal segments together. This genus is dis- 

 tinguished from Ommatius Wiedemann, 1821, through the 

 toothed hind femur. 



Distribution: Palaearctic: Merodontina sikMmensis 

 Enderlein (1914). 



This species seems to be in the southern boundary of 

 the Palaearctic region in the most northern part of 

 India. 



Genus Emphysomera Schiner 



FiGUBES 304, 752, 1362, 1371 



Emphysomera Schiner, Verh. zool.-bot. Ges. Wien, vol. 16, p. 

 845, 1866. Type of genue: Ommatius conopsoides Wiede- 

 mann, 1828, by original designation. 



Small flies, separated from Ommatius Wiedemann 

 chiefly on the basis of the clavate abdomen. This group 

 of flies is found largely in southern Asia, with two 

 species in Ethiopia. Length 8 to 12 mm. 



Head, lateral aspect : The head is of medium length, 

 the occiput short, scarcely visible on the upper half, 

 with the upper bristles strong and proclinate. The 

 face is quite short, scarcely visible in profile even be- 

 low. The proboscis is short, strongly swollen at the
