250 Rev. V. I). Morice's Notes on Australian Sawflies. 



of photographs (or in a very few cases of drawings) taken 

 by myself from B.M. or Hope Coll. specimens, the parts 

 figured having nearly always been prepared by Mr. A. 

 Cant. F.E.S., in the Museum " Setting-room " by the kind 

 permission of Dr. Gahan or Professor Poulton. I am 

 greatly indebted to Mr. Cant for the invaluable assistance 

 I have received from him in this matter, and am glad to 

 think that his preparations will henceforth be a part (and, 

 I think, a very useful part) of the Collections at Oxford and 

 South Kensington. The photographs representing details 

 of saws in the various species of Perga and Xyloperga were 

 all taken at the same magnification, but this is not the 

 case with the other figures. It will be noticed that in some 

 of those representing antennae the two short basal joints 

 are missing, but these joints are not particularly character- 

 istic, and their omission is therefore of little consequence. 



When these notes were commenced, and even after con- 

 siderable progress had been made with them, they were 

 intended merely as materials for a revision of the Genus 

 Perga. But I afterwards resolved to adopt a suggestion 

 made to me by Mr. Turner that they should include also 

 some account of such other Australian Sawflies as were 

 represented in the Collections to which I had access. The 

 materials available for this part of my work were quite 

 insufficient for the clearing up of many questions, which, 

 as long as they remain unsettled, will render the production 

 of anything that deserves to be called a " Monograph " 

 impossible. Still, as I have seen all the Types of described 

 species in some genera, and either Types or specimens 

 which I have reason to believe are correctly named in all 

 hut one of the others, it seems worth while to indicate in 

 tabular form the characters by which they seem most easily 

 distinguishable in the specimens before me, even when I 

 cannot be sure that these characters are of specific value. 



Accordingly I have prepared dichotomic Tabulations 

 or Synopses, first of the genera, and afterwards of the 

 species in each genus of which more than a single species 

 is known. Except in the cases of Perga and Pterygophorus, 

 where some trouble has been taken to make the order in 

 which the species are arranged correspond to my idea of 

 their natural affinities, I have aimed in these Synopses 

 at nothing more than to facilitate the naming by collectors 

 of their specimens, and have employed indifferently what- 

 ever characters, whether of structure or merely of colora-
