45 days from the egg to the imago, a period about the same here as Palla. 

 I am iiicHned to think, however, that in its home in the Sierras its growth 

 is not so rapid, probably requiring a longer time for development, and finally 

 passing the winter in the chrysalis state instead of producing the imago as 

 it did here. A part of this is conjecture, however, for though I learned 

 from Mr. McGlashan's letters that his chrysalids had not hatched some 

 time after mine had, I do not know but they may have done so 

 since. With us the species would be double brooded the same as Palla, 

 the last chrysalids hibernating. 



Like Palla, the food plant is willow. As soon as hatched the larvae 

 begin to fasten leaves together with silk, forming a retreat or vivarium 

 within which they live together. When at rest the anterior part of the 

 body is bent to one side. This was noticed more after the second moult 

 than before, but continued through the larval stage. During the early 

 periods they ate the parenchyma of the leaves, leaving the framework. 

 When ready to spin their cocoons some leaves were fastened together, and 

 inside this was spun the cocoon that did T:ot differ materially from other 

 species. 



BRITISH COLUMBIAN HYMENOPTERA. 



BY GEO. W. TAYLOR, VICTORIA, B. C, 



In the June number of the Canadian Entomologist, p. 114, there is 

 a paper by M. L'Abbe Provancher, containing descriptions of a new genus, 

 Platysoma, and 7 new species of Canadian Hymenoptera. Six of these 

 new species, Ich. Vafuouveriensis, Platysoma tibialis, Limneria compacta, 

 Mesoleptus fasciatus, Phylax pacificus and Phylax niger, are from Van- 

 couver Island, and I am under the impression, for reasons which I will 

 now state, that the specimens of these species from which M. Provancher's 

 descriptions were made were from my collection, though no mention of 

 my name appears in M. Provancher's paper. 



In February, 1883, in response to the request of Mr. W. Brodie, of 

 Toronto, I sent to him specimens of all the Vancouver Hymenoptera I 

 then possessed. In June, 18 S3, Mr. Brodie returned named 81 species, 

 which I have enumerated in vol. xvi., p. 77, of the Can. Ent., and a few 

 more were returned to me in Feb., 1885, but he made no mention what- 

 ever of the fact that any of the species named were new.
