"AcARixA," OR Mites. 



The Red Spider, "Tctranychus sp.," and the Clover Mite, "Bryobia 

 pratensls." often found on apple, plum and many ornamental trees from 

 England, Eastern Canada and the United States, the eggs being de- 

 posited around the base of the small twigs and laterals. 



Pear Blister Mite, " Eriophyes pyri," in the bud scales of pear-trees 

 from England and the United States. 



This about completes the list of insects that have arrived in British 

 Columbia as undesirable immigrants, and have been treated accordingly.

BOMBVCIA IMPROVISA, EDW. AND ITS CONGENERS. 



In Dyar's list of orth AmericaN nLepidoptera (1902) the name 

 " tcarl'n" Edw. is given as a synonym of Bombycia " itnprovisa" Edvv. 

 On our finding two Bombycias in the Duncans District of Vancouver 

 Island somewhat alike, it was at first thought that one was merely a 

 variety of the other, namely, "i/ri proviso" the species and "tearlii" the 

 variety. But for the last two or three years I have felt convinced that 

 the two forms were distinct species. This conviction has recently been 

 confirmed by Messrs. Barnes and McDunnough in the September, 1910, 

 number of the New York Entomological Society (Vol. XVII., No. 3), 

 where, under the heading of "Bombycia fasciata, new species," is given 

 a description of the moth which we have been inclined to regard as 

 "tearlii" Edw., but which Messrs. Barnes and McDunnough state is 

 not that species. 1 may remark that the insect figured in Holland's 

 "Moth Book" as B. tearlii Edw. is evidently B. improvisa, Edw. 



For the benefit of anyone who has not the Journal of the New York 

 Entomological Society to refer to, I will quote the description and re- 

 marks, as follows : 



Bombycia fasciata, new species. 



"Collar and prothorax rudd\ brown: patagia crested, gray, edged 

 with dark brown ; posterior portion of thorax gray ; abdomen smoky 

 brown ; base of legs clothed with rosy hairs ; primaries, ground color 

 light purple brown, suffused at base and terminal portion of wing 

 with light whitish green and crossed by a broad median band of the 

 same color ; the basal green portion of wing is bordered by an in- 

 distinct geminate, outwardly oblique, subbasal line, angled inwardly
