MANITOBA MICRO-LEPIDOPTERA. 



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



The following list of Micro-Lepidoptera taken in the Province of 

 Manitoba, is published for the purpose of recording the distribution of 

 species, as well as an incentive to the collectors of the locality to make 

 more than ordinary efforts to add to the number. The work that has 

 already been done is most gratifying, and compares very favourably with 

 local lists of many of the States, from which a great deal more would have 

 been expected. For instance, the number of Tortricids alone exceeds the 

 number credited to the State of New Jersey, in Prof John B. Smith's list 

 of 1899. But even in this family I have twenty-five or more additional 

 species which appear to be new, but that are not described at the present 

 time owing to the fact that most of them occur as only one or two speci- 

 mens of a kind, and oftentimes more or less rubbed. I am quite sure that 

 the work of another year or two will enable us to establish a list of Tortri- 

 cids from this one province alone of not less than two hundred and fifty 

 species. The same proportions will probably follow in the other families 

 embraced under this general head. Collectors must not forget that each 

 different manner of collecting produces results not found in any other 

 way. Daylight with net, sugaring and light at night, and most valuable, 

 breeding from the larvge, also different hours of the day must be worked. 

 Some species fiy only very early m the morning, others only at twilight ; 

 likewise different localities, such as the prairies, along streams, in thickets 

 and underbrush, and in the woods or forest, each will contribute some 

 species not found elsewhere. The proof of these remarks will be found in 

 the localities given in the lists below, regardless of how small the numbers 

 were. Each collector has secured species not found by some or any of 

 the others, showing the result of work along individual lines in favourite 

 spots or methods. 



I take pleasure in acknowledging my indebtedness to the following 

 gentlemen for the privilege of studying and making record of their 

 captures, as well as for the many specimens they have generously 

 permitted me to retain : 



Mr. E. Firmstone Heath has for several years sent me his captures, 

 all of which are recorded under the name Cartwright. 



Mr. Norman Criddle has sent me a very large number of most 

 interesting species, all of them most beautifully and carefully expanded 

 His captures are recorded as Awevie.
