Eyes contiguous in the male, separate ia the female. 

 Thorax a little broader than the head, broader posteriorly 

 than anteriorly. Abdomen broader than the thorax. The 

 abdomen of Lomatia is slender, rather elongate and parallel 

 sided; that of Oncodocera is broad and not much longer than 

 wide; the species of Comptosia have their abdomen generally 

 like that of Lomatia, but vary to something approaching but 

 not quite like that of Oncodocera. The latter case only 

 occurs in a few large species, which can be readily separated 

 by the difference in the loop of the radial vein.

 and 185. 



Description. — In the male the wing contains two recur- 

 rent veinlets situated on the vein between the discal and 

 third posterior cells, one running into each of these cells; 

 this character is not represented in the female nor in the 

 other species placed under this genus. 



Hab. — Described from Western Australia; there are 

 two males and two females from this State in the Austra- 

 lian Museum. In the Macleay Museum there are two males 

 and two females from South Australia.

Synonymy. — The above synonymy appears to be correct. 

 The species must not be confused with various species of the 

 genus Comptosia, which have a general similar appearance; 

 the curvature of the radial vein will readily distinguish them. 



Hab. — In the Macleay Museum there are seven speci- 

 mens from South Australia and one from Piper's Flats, New 

 South Wales. In Dr. Ferguson's collection there is one speci- 

 men from Victoria labelled "Mallee."
