Group 1. 



Corpus hirtum, setosum. Facies apud epistoma valde con- 

 rexa. Mystax densissime pilosus. Proboscis valida, lanceolata. 

 Antennarum articulus lus 2o plus duplo longior ; 3us lo non lon- 

 gior ; arista 3o duplo longior. Pedes validi, pilosi, spinosi. Mas. — 

 Abdomen oblanceolatum, apice fasciculatum. Fa?m. — Abdomen 

 bis triente basali longi-obconicum, triente apicali valde compressum, 

 spiniforme. 



Mediastinal vein ending at a little beyond half the length of 

 the wing. Forks of the radial vein very long ; fore fork hardly un- 

 dulating, connected with the subcostal very near the tip of the latter 

 and near the tip of the wing; hind fork slightly curved forward, 

 joining the costal at very little in front of the tip of the wing very 

 near the cubital, and connected with it by a transverse veinlet. 

 First extemo-medial hardly curved, but nearly parallel to the cubi- 

 tal, with which it is connected by a transverse veinlet at one- 

 third of the length of the discal areolet; second almost straight; 

 third slightly curved, forming a very slightly obtuse angle with the 

 praebrachial, joining the fourth far from the border of the wing. 

 Subanal joining the anal at some distance from the border. The 

 shorter third joint of the antennae seems to be the only character 

 which distinguishes this genus from Mallophora.
