black, sides with l)lack hairs ; under side red on basal segments,

MYGTEROMYIA, Philippi.

This genus was established by the author for Pangonia cunica, 

 Bigot, from Chili, and Bigot later added other species from Bra- 

 zil, Cape of Good Hope and one from India. Philippi gives the 

 chief characteristics as : Head narrower than thorax, elongated 

 in front. Eyes naked. Ocelli present, .\nteunal joints rather 

 longer and narrower than in Pangonia. Palpi Particulate, the 

 first joint short, the second elongated, compressed, narrow, the 

 apex rounded. Legs slender. Wings with first posterior cell closed. 

 Dr. Lutz in Zool. Jahrb., Suppl. x, 4, p. 62, 5 (1909), remarks 

 that the genus can only be retained for the Chilian species with 

 naked eyes, the four Brazilian species described by Bigot having 

 eyes distinctly pubescent. The description of the Indian species 

 is too short and inconplete to enable anyone to judge to what 

 genus it belongs, and I have seen no specimen from India at all 

 resembling the original description.

This genus, characterized by the short first and second joints 

 of antennae, the second one shorter than the first, and by the 

 usually hyaline wings, has not hitherto been represented in the 

 Oriental Region, but a female specimen in the Indian Museum 

 from Bhura, Naini Tal district, United Provinces, India, is no 

 doubt a species of Silvius not unlike in general appearance to the 

 European s]:>ecies Silvius vitidi, Fabr., but distinct.
