206 Miss G. Ricardo on the 



lighter in colour. Abdomen with the first segment more 

 yellowish, and with hardly a trace of the blackish-brown 

 hand on posterior border ; the dark colour on the second 

 segment does not join in the centre, but is represented as a 

 narrow black stripe on each side of the yellow spot, with the 

 apex converging towards the centre.

Wiedemann described this species under Chrysops, but 

 Macquart formed the genus Ectenopsis for it, considering 

 that the pi'olongation of the face was its most striking 

 characteristic. Loew remarks that Macquart had probably 

 not seen the species, the type of which, described from an 

 unknown locality, was in the Berlin Museum; and Loew 

 considered the creation of a new genus unnecessary. A 

 long series of the females of the species being now in the 

 Brit. Mus. Coll , I have been able to establish the identity of 

 Bigot's two types with it, and find that the antennae have 

 the third joint with eight divisions, which will necessitate 

 removing it to the first division of the Pangoninae, and pre- 

 cludes it being kept in the genus Chrysops. It must evidently 

 be kept as a separate genus, reverting to Macquart's name. 



The generic characteristics are the form of the anttmuc. as 

 above stated, the shape of the face, which is convex and 

 short, the forehead being long and concave and broad; the 

 proLi scis is short, the palpi small, cylindrical. Eyes bare.
