BOMBILIDiE. 

 CoMPTOSIA CORCULUM, Walk. 



This is a mountain species, occurring in moderate 

 numbers on Mt. Wellington, between 2,000 and 3,000 tt., 

 where it ca.n be taken throughout the summer. The Tas- 

 manian specimens do not differ from C . geovietrica, Macq. 

 other than in the number of submarginal cells, and in 

 its average larger size. The method of dividing one sub- 

 marginal cell into two is very variable. Sometimes a 

 veinlet joins the radial vein with the upper branch of the 

 cubital fork. At other times the radial vein takes a 

 sharp curve and runs down to the upper branch of tne 

 cubital fork, along which it runs for a more or less short 

 distance, then runs up to resume the normal course.. It 

 sometimes happens that the aj.acal portion of the radial 

 vein runs to meet the basal portion of the radial vein, 

 forming an area enclosed similar to the areolet of some 

 Ichneumonidce.
