Rev. F. D. Morice's Notes on Australian Sawflies. 249 



Types, the want of which access has greatly impaired the 

 value of much recent work * on Australian forms, I have 

 I km mi singularly fortunate in being occupied on these 

 investigations exactly when and where I could at once 

 take counsel on any difficulty that might arise with a 

 colleague who, of all men, was perhaps the best qualified 

 to assist me. Mr. Rowland E. Turner, well known to all 

 Hvmenopterists as the author of many important memoirs 

 on various groups of exotic Aculeates, had long devoted 

 himself to voluntary work in arranging and augmenting 

 the B.M. collections of Hymenoptera, and had lately 

 received a formal appointment as an honorary member of 

 the Museum Staff. He had previously resided for twenty 

 years in North Queensland, and both there and in other 

 parts of Australia (Swan River, Tasmania, the neighbour- 

 hood of Sydney, etc.) made large entomological collections, 

 all which he has now presented to B.M. Though more 

 specially interested in other groups, he had by no means 

 neglected the Sawflies — in fact, several Australian species 

 and at least two genera are known to me only through 

 his captures. Being myself almost entirely ignorant 

 of " exotic " insects, Hymenopterous or otherwise, and 

 having only the vaguest ideas about the geography, 

 physical features, climate, seasons, etc., etc.. of the Aus- 

 tralian " Realm," I naturally seized every opportunity 

 of profiting by Mr. Turner's familiarity with all theso 

 subjects, and though I cannot regret that I have done so. 

 I am conscience-stricken when I think how unscrupulously 

 I have exploited his good nature. 



I have also to thank an American colleague, Mr. S. A. 

 Rohwer of Washington, for several very kind and en- 

 couraging letters, and for communicating to me unpublished 

 notes of his own on some of the specimens which I have 

 examined, as well as for copies of many of his Separata, 

 especially his Classified/ ion of the Suborder Chalastogastra 

 (Proc. Ent. Soc. Washington. 1911) and Genotypes of the 

 Sawflies <tn<l Woodwasps (U.S. Dep. Auric. Technical Series 

 No. 20. Part II. Washington L911).

* E. (j. Konow"s attempts to classify the known species of Perga 

 and Pterygophorus. Having in most eases only old and inadequate 

 diagnoses and figures to guide him, lie naturally made many mistakes 

 both in identifying species, and in deciding where to place them in 

 his Tables.
