51b NEW SPECIES OF PHYTOPHAGOUS HYMENOPTERA. 



mens being found on dead saplings; at other times I have found 

 it decidedly rare, having only occasionally come across it, some- 

 times on blossom. P. insignia and interruptus and Eurys incon- 

 spicuct are so uncommon that I am unable to say whether they 

 belong to the forest or scrub, nearly all the specimens of these 

 species that I have captured having been found on blossom, 

 usually not far from scrub. The two species of Clarissa, Hylo- 

 toma apicale, and Pterygophorus uniformis are undoubtedly scrub 

 insects; the last named, which is the only sawfly that I have 

 found in large numbers, being sometimes very abundant in 

 March, April and May on a vine which grows up after scrub 

 has been felled, the leaves of which, I have very little doubt, 

 form the food of the larvae. 



My thanks are due to Mr. W. W. Froggatt for assistance in 

 preparing this paper, especially for confirming my opinion as to 

 the generic identity of Oryssus Queenslandensis, Letreille's defini- 

 tion of the genus not being accessible to me.
