O 14 Provincial Miseum Report. 1918 



New British Columbia Lepidoptera. 



Under this beading we publish an annotated list of those new species and varieties which 

 have been described during the past season. We believe that this list will be of value to those 

 entomologists in the Province who are unable to keep in touch with all the current literature 

 on the subject, but who are desirous of keeping their collections and check-lists up to date in 

 nomenclature and scientific arrangement. 



Glaucopsijclie lygdamvus Columbia Skin. This new race of lygdamus was described by Dr. 

 Henry Skinner in the Ent. News for May, 1917. The type and paratypes are from Port Columbia, 

 Wash. Amongst other localities mentioned for this species is Corfield, Vancouver. We presume 

 this is meant for Corfield, near Duncan, on Vancouver Island. This pretty blue butterfly is 

 fairly common all over the Island about May, and has been going under the name of G. lygdamus 

 behrii Edw. {vide Report, Provincial Museum, 1916). The true behrii is a California race of 

 lygdamus, with San Francisco as its probable nimotypical locality; Columbia differs from 

 behrii in being of a much deeper shade of blue and the spots on the under-side of the wings 

 being larger. 



In Vol. III., No. 4, Cont. Lept. No. Amer., March, 1917, Messrs. Barnes and McDunnougb 

 describe a number of new species and varieties of Geoinetridoa, amongst which are eight new 

 to British Columbia. As these " Contributions " were published subsequent to the issuance of 

 their new check-list, the following additions must be made to it : — 



Trichodesia albovitiata tenuifascnata B. & McD. Tbis form was described from Spirit Lake, 

 Idaho. In the Barnes collection there were specimens from Wellington, B.C., and the writer 

 has a specimen taken by Mr. W. H. Dauby at Ymir in 1900. In this variety the white band 

 of primaries is much narrower, being only 1 mm. in widtb. 



Thera g'eorgii benesignata B. & McD. This racial name has been given to tbe Vancouver 

 Island form on account of its larger size, paler colour, and the strong contrast between the 

 brown median and basal areas and the ground colour. Typical georgii is now restricted to 

 the Nevada species. The types of benesignata are^ from Wellington and the paratypes from 

 Duncan. 



Mesoleuca gratulaia latialbata B. & McD. Described from three specimens from Plumas 

 County, Cal. In this form the median white band is strongly constricted centrally below the 

 cell, due to an outward bulge in tbe dark basal area and a strong inward bend below vein 4 

 of the outer dark area. I have a specimen from Kaslo which Dr. McDunnougb considers this 

 form, although tbe basal line is not quite typical. 



Epirrhw plebeculata vivida B. & McD. Tbis is the species hitherto known as Rheumaptera 

 rubrosuffusata Pack., which occurs commonly throughout the Island and Lower Mainland. 

 Rubrosuffusata has been found to be a synonym of plebeculata, which was described by Guenee, 

 from California, and the racial name of vivida is proposed for our Vancouver Island form on 

 account of the coloration being much better defined. 



In describing a new species, Phasiane ponderosa, Messrs. Barnes and McDunnougb mention 

 a variety of it under the form name of dcniaeulata, in which the cross-lines tend to become 

 obsolescent, especially in the females. The types are from Calgary, Alta., but one of tbe female 

 paratypes is from Field, B.C. We have two rather worn females, one from Atlin, taken by E. M. 

 Anderson, and one from Cbilcotin, taken by W. A. Newcombe, so that although uucommon it is 

 widely distributed. 



Itame pluiuosata B. & McD. This pretty yellow and brown geometer was described from 

 specimens taken in various localities in Arizona and Utah. We have a male specimen from 

 Mount McLean near Lillooet, taken in July, 1916, by E. M. Anderson. It is rather remarkable 

 that this species should turn up here, as it is a long way from its nimotypical locality; it is 

 apparently a high altitude species and may turn up on any of the high mountains in tbe inter- 

 vening country. 



Cleora satisfaeta B. & McD. Described from one male and one female taken at Kaslo. 

 This is closer in general habitus to cxcclsarw Streck and albescens Hulst. than to any other 

 Cleora, that occurs in the Province. 



JEthdloptera anticaria fuinata B. & McD. This is the insect from Kaslo that has been 

 previously known as JE. intcttaia Walk. Dr. McDunnougb states that anticaria should be used 

 for the common Eastern species instead of intexlata, and proposes the name of fumata for tbe
