show a change in colouring from warm brown to a greyish-brown, 

 caused possibly either by a change of food-plant or to different climatic 

 conditions. 



I also remarked in the same paper that I had not seen the typical 

 form of Mesoleuca vasiliata Gue., although the variety niveifasciata Hulst 

 was taken regularly on Vancouver Island. On further investigation, 

 however, 1 find that it does occur here, but very sparingly. Mr. G. O. 

 Day, of Duncan, has taken a few, and so has Mr. A. W. Hanham. 1 

 found a couple of specimens when going over Mr. E. Skinner's collection 

 which were taken by him at Duncan, B.C., some years ago ; and also 

 found one in the collection of Mr. A. H. Bush, of Vancouver, who has 

 been collecting for many years. 



There are also two more species of this genus to add to the list : 

 Mesoleuca formosa Hulst, taken by the late Mr. Livingstone at Cowichan 

 Bay, B.C., and now in the collection of Mr. L. W. Swett, of Boston, 

 Mass. This is a very rare insect and I am glad to have the record. It 

 was placed by Hulst in the genus Philerme, but it is a true Mesoleuca. 

 The other one, M. atrifasciata Hulst, I found in the collection of Mr. E. 

 Skinner, and was labelled " Possibly a var. of E. nubilata." It is listed 

 bv Dyar as a synonym of M. immanata, which it in no way resembles. 

 It is a very striking insect, as may be seen from the t_ype which is figured 

 in Holland's Moth Book, Plate 44, Fig. 8, under the name of Cleora 

 atrifasciaria. 



The genus Hydriomena I liave treated of in my previous paper, and 

 I will now pass on to a variety of Triphosa haesitata which occurs here, 

 but which has evidently been overlooked. Mr. Swett first drew my 

 attention to this variety, he having found it in the collection of Mr. C. 

 Livingstone, which passed into his hands some time ago ; since then I 

 have taken two specimens in Victoria. It has a mottled appearance and 

 is called var. pustularia Hy. Edwards. 



Marmopteryx marmorata Pack. Two specimens of this handsome 

 insect were taken at Okanagan Falls on May /th, 1913. Its natural 

 habitat is California. In an article by R. F. Pearsall, in the Bull. 

 Broeiklyn Ent. Society, CJct., 1914, on Gypsochroa designata Hufnagel, 

 he says that on comparing the genitalia and markings with the European 

 designata he finds them dift'erent, and proposes a new name for our 

 species, viz., emendata Pearsall, G. designata being strictly European. 



Petrophora circumvallaria Taylor. One specimen taken at Atlin on 

 June 13th, 1914. This is a nice capture, and again illustrates the simi- 

 larity of the fauna of northern British Columbia and southern Alberta. 

 Both Messrs. I'arnes and McDunnough and Mr. F. Wolley-Dod claim 

 that this species is a synonym of the European turbata Hub., but until 

 the genitalia of the two forms are compared I would hesitate to accept 

 this, as I believe that we get very few of the European species in this 

 country.
