Hah. — C pygmrea ranges from Mell)ourne up to the central 

 (x>ast of New South Wales. In Victoria it has been taken well 

 inland at .Vlexandra, but in New iSouth Wales all the recorded 

 localities are within fifty miles of the coast. The following is a 

 list of the localities: — ^Mell)Ourne((j9.types), Alexandra(numerous 

 examples taken Wy Mr. liillinghurst), lUawarra district, N.8.^^^, 

 (Otford, Lily Vale, Heathcote, a large number taken by myself), 

 Sydney District, N.S.W.,(Duck Creek, Auburn, fairly common), 

 Nepean River ;<iid tributaries(Glenbi'ook, Menangle), Ourimbah 

 (common). It emerges at the end of February, is most abundant 

 during March and .Vpril, and may be taken right through May 

 and June. 



The onlv known locality for C. montari'i at present is Medlow, 

 Blue Mountains, N.H.W., where I took the type-male and female 

 on January 19th, 1910. From the appearance of the specimens, 

 I should say that they had been on the wing considerably over a 

 month (the border of the wing of the ^ is slightly torn in one or 

 two places). The fact tha(. larvae found on November 5th, 1910, 

 were practically full-fed, leads me to give the middle or end of 

 November as the probable date of emergence of this species. It 

 probably does not continue on the wing beyond February. 



Life-History of C. pyyrrKVd. 



On an}' warm still day in ^larch or April, the female may be 

 seen ovipositing in her favourite haunts. These are the little 

 grass-fringed bays aiid corners that occur occasionally along the 

 creeks in the hilly fi»untry round Sydney. The oviposition is 

 carried out as follows. Suddenly, from the top of some bush or 

 tree where she has been resting, the female will dart down to the 

 water, and, in a most hurried and restless manner, begin to wash 

 out the eggs, in large clusters, from the open vulva of segment 8, 

 which is quite unprovided with any projecting ovipositor. This 

 is done by continual wavings up and down of the abdomen, each 

 downward stroke bringing it in contact with the water. During 

 the whole time the Might of the female is so bewildering that it 

 is difficult to follow, and so rapid is their motion that I have 

 often seen the body of the insect poised with the wings practically
