ASSINIBOIA MICRO-LEPIDOPTERA, COLLECTED BY MR 



T. N. WILLING. 



BY W. D. KKARFOTT, MONTCLAIR, N. J. 



I am very much indebted to Mr. T. N. Willing, of Regina, Assa., for 

 the privilege of working up a very interesting collection of Micro-Lepidop- 

 tera. It is particularly notable in recording a number of species that have 

 hitherto been only known by the types, and especially so in establishing 

 a wide range of territory »to species that have been only recorded 

 from California. Following this paper I have one in preparation on the 

 same subject, from material collected in Manitoba by Messrs. Heath, 

 Criddle and Dennis, to be followed in its turn by one on Micro-Lepidop- 

 tera from Western British Columbia, collected by Dr. Taylor and Mr. 

 Bryant ; later I hope to be in possession of sufficient material from the 

 territory east and north of Toronto, which has been less worked than any 

 part of North America, for a fourth paper. It is most gratifying to observe 

 the very great interest in these small insects that has arisen throughout 

 Canada. 



TORTRICID^. 



Olethretites consangninaiia, Wlsra. — One specimen ; Macleod, VII. 

 2. The most eastern record for this species, common in British Columbia 

 and California. 



Okthreides deceptaiia, sp. nov. — Palpi, head and thorax pale gray, 

 thickly sprinkled with darker gray atoms, antennte pale gray. Front wing 

 pale gray, marked with obscure darker gray. The darker shade forming 

 a basal patch, a more or less obsolete middle fascia and streaks before 

 outer margin. The basal patch covers on costal and dorsal margins a 

 fifth of length of wing, but extends outward on middle one-quarter, the 

 outer edge is slightly indented half way between middle and costa, below 

 middle the edge is irregular and almost lost on its lower fourth. The 

 basal patch is thickly covered with darker, nearly black strigulse and 

 dots, the former parallel to the outer margin of patch. Central dark fascia 

 from middle of costa and narrowest just below casta; its inner edge 

 slightly indented below costa, broadly indented on cell and slightly above 

 dorsal margin ; its outer edge is slightly indented below costa, deeply and 

 narrowly at end of cell, thence obliquely towards anal angle, but before 



February, 1905.
