from Vancouver Island. Until undoubted specimens of brucei are taken in British Columbia I 



think- it is better to eliminate this species from our B.C. Check-list. 



Pterophorus (Oidcematophonts) paleaceus Zell. Recorded from Wellington. Specimens 



under this name in the Bryant collection did not seem to agree with the description of that 

 species and were submitted to Dr. Lindsey, who pronounced them to he " rather large specimens 

 of corpus B. & L., not quite typical, but certainly not paleaceus Zell." 



Pterophorus (Oidwmatopliorus) eupatorii Fern. This record in our list was copied from 

 Dyar's Catalogue (Bull. 52, U.S.N.M.), wherein he gives Vancouver Island, together with New 

 York and California, as localities for this species. Barnes and Lindsey in their " Revision " give 

 a detailed discussion of eupatorii Fern., guttatus Wals., and mathewianus Zell.. three very closely 

 allied species and which have given rise to a great deal of confusion in the past. The conclusions 

 arrived at show that eupatorii is distinctly Eastern and does not occur on the Pacific slope. 



In concluding this paper on the British Columbia Pterophoridae, I would like to point out 

 two important pieces of biological work that remain for our local entomologists to undertake, 

 and that is the working-out of the life-histories of (1) Plalyptilia patlidactyla Haw. and pica 

 Wals.. and (2) P. carduidactyla Riley and percngdaciyla Wals. Careful breeding from the ova 

 of known females, full notes on the different larval instars, together with careful comparison of 

 the resulting imagines, will do much to prove the specific identity or otherwise of the species 

 indicated. 



The following family, with its one North American species, is included here as it is so very 

 closely allied to the Pterophoridae. 



FAMILY ALUCITIDAE LINN. 

 Genus ALUC1TA Linn. 



Alucita Linnaeus, Syst. Nat. (Ed. X.), 1. 542, 1758. 



Onieodes Latreille, Precis. Car. Ins. 14S, 179t>. 



Characters: Ocelli present. Proboscis well developed. Labial palpi strong. Both primaries 

 and secondaries deeply cleft iuto six lobes each. The under-surface of the secondaries lacks 

 the black scales which occur in the Pterophoridae and the legs are of normal length. 



1. Alucita Montana Cockered, Ent. Mo. Mag., XXV., 213, 1S89. 



Onieodes hexadactyla Fernald (not Linn.), List. Lep. No. Anier., 88, 1891. 



Primaries greyish-tawny, crossed by a wide dark-brown median band margined narrowly 

 with white, which forks on the first two lobes; a subtermiual band, narrower on the first two 

 lobes, is also margined with white. Secondaries checkered with dark brown, tawny, and white. 



This species is the Orncodoes hexadactyla of our local lists, a European species with which 

 our North American species has generally been considered conspecific, but according to Barnes 

 and Lindsey hexadactyla is much lighter and more ochreous in general appearance and entirely 

 lacks pure white scales. 



Montana has a wide distribution in North America, occurring from Vancouver Island to 

 Ontario and from New York to California.
