NOTES OF CAPTURES OF LEPIDOPTERA AT SUGAR AND 

 LIGHT DURING 1910 AT MY FARM ON THE LONG 

 RIVER, NEAR CARTWRIGHT, SOUTHERN MANI- 

 TOBA, AND ALSO OF THE RESULTS OF 

 THE OVERHAULING OF SEVERAL 

 CASES OF DUPLICATES. 



BY E. FIRMSTONE HEATH, CARTWRIGHT, MAN. 



The collecting season of 19 10 was in many respects so very peculiar 

 that I think some description of it, and a fuller account of my captures 

 than can be given in the very useful Hst annually compiled by Mr. Arthur 

 Gibson may be interesting. 



The snow was all gone by March 12th, and the brook wliich courses 

 through my land was free from ice, but the weather during the rest of the 

 month was cold and stormy, and nothing appeared on the wing. 



For nearly all of the identifications I am indebted to Dr. J. B. Smith, 

 and the numbers accompanying the names are those of Dr. Dyar's List of 

 N. A. Lepidoptera, 1902. 



April came in warmer, and on the ist I took a single Semioscopsis 

 inor7iata Wlsm. (5895) at light ; and on the 2nd and 3rd a few Homoglaa 

 hircina Morr. (2256) at sugar. The first Pieris rapce Linn. (40) were 

 seen on the 20th, after which they were very numerous, and I feared we 

 were in for another dose like that of the previous year, when the cabbage 

 plot had to be carefully gone over every morning, and as many as possible 

 of the ovipositing females netted, in order to save my plants. Strange to 

 say, in the fall the caterpillars gave very little trouble. Either the 

 extremely hot and dry weather had in some way caused a failure of the 

 spring brood, through scarcity of food-plant, or the contents of some 

 parasitized pupce I had sent in from Montreal had established themselves 

 to some purpose. Up to the date on which I am writing (May 2nd) I 

 have not seen a single Pieris rap(2, though hibernated specimens of other 

 genera are to be frequenily met with. The potato crop was seriously 

 damaged by the Colorado beetles. In fact, the crop was almost a total 

 failure from the drought, in addition to the beetle attack. It used to be 

 said that the beetle could not survive the Manitoban winter, and in the 

 early years of my potato growing it used only to appear in small numbers, 

 and at intervals of several years. But now, owing, I am afraid, to the 

 neglect of potato growers in destroying the larvse whenever seen, no 

 matter in how small a number, in these occasional appearances, it has 

 become acclimatized, and is going to be very troublesome. 1 have 

 several times during the last few years seen one of the Soldier Bugs,
