THE CANADIAN ENTOMOLOGIST. 17 



Kirby, in his List of the Hymenoptera in the British Museum, records 

 several species of Tenthredinida^ and Uroceridfe. To Mr. Taylor, how- 

 ever, is due a large proportion of our knowledge of the Hymenopterous 

 fauna. In Vol. XVI. and XVII. he published a list of eighty-one species, 

 from the vicinity of Victoria, and he continued to collect there and sent 

 specimens to Mr. Fletcher and myself until he came to reside in Ottawa a 

 few years ago. He then brought his collection with him to this city, and 

 on his return to the Pacific Coast he placed all the remaining Hymen- 

 optera in my hands, on the condition that I should prepare a list of them 

 for publication, in revision and enlargement of his own earlier list, in which 

 there are some errors in determination. 



The collection has proved to be a most interesting one, and to con- 

 tain quite a number of new insects. It is, as might be expected, deficient 

 in the smaller forms, such as Cynipidse, Braconidfe, Chalcidid^e, and 

 Proctotrypidse. As time has permitted, I have proceeded with the 

 determination of these insects, and have published descriptions (Cax. 

 Ent., Vol. XXVI.) of some new species. The Aculeata require further 

 study, especially such genera as Andrena, Halictus, Osmia, etc., before a 

 satisfactory list can be made of them. Mr. Taylor is now resident at 

 Nanaimo, and it is to be hoped that his duties will aftbrd him oppor- 

 tunity to collect in that district. The publication of a list (even though 

 imperfect) of the recorded species may perhaps stimulate others to join 

 with him in a more systematic collection of the Hymenoptera of Van- 

 couver Island, which offers so rich a field for study. The fauna is 

 evidently a very extensive one, containing many species occurring in the 

 Pacific States, while in the northern portion of the Island and on the 

 mountains there should be a large intermingling of species inhabiting 

 Alaska and the Rocky Mountains. It would not require much effort to 

 increase many-fold the number of species at present known. The order 

 Hymenoptera is so rich in species, and the conditions of the occurrence 

 of the species are so varied, that it will long be possible to discover forms 

 new to science, even in Ontario, where the fauna is so much better known. 

 In the vast and diversified regions of the Pacific Slope, such new and 

 undescribed species must be almost unlimited.
