86 THE CANADIAN ENTOMOLOGIST 



Vol. XXXVII, page 102), I determined to follow his exainple during the 

 autumn of 1905. After many weary visits to baited trees, and finding 

 nothing more desirable than Orthosia ferniginoides, Agrotis ypsilon, 

 Peridroma saucia, Xylina antennata, and Plathypena scabra, I 

 abandoned the undertaking early in October, with the conclusion that 

 there were no Scopelosomas in rhis locality, and certainly no such variety 

 of moths as Mr. Engel met with. This proved to be a mistake as far as 

 Scopelosomas were concerned, for during the following maple-sugar season 

 I took over one hundred specimens that were feeding upon sap which 

 oozed from wounds in the maple-trees caused by the common Sapsucker 

 — the yellow-bellied Woodpecker (Sphyrapicus variiis). In the sugar 

 woods where the trees were tapped for syrup, many had become drowned 

 in the sap-pails. I found that submerged specimens were spoiled, but 

 those floating and not saturated were fit for mounting. 



Subsequently I read Mr. Engel's article again, and noticed that he 

 did not mention any captures of ^copelosoma before October 21st. I 

 had received the impression when first reading it that he had taken 

 specimens of this genus much earlier, and otiiers, perhaps, have made the 

 same mistake. Accordingly, last autumn (1906; I baited a number of 

 trees, and continued to visit them early in the evenings without meeting 

 any particularly desirable specimens until October 26th, when one 

 Scopelosoma was captured. On the next evening, which was rainy, I 

 took seventeen specimens, on Nov. 3rd. twenty-two, Nov. loth fifteen, 

 Nov. 17th seventy-one, Nov. 26th thirty-two, and there were other dates 

 when I took from four to six examples. These moths do not come to 

 feed at the bait to any extent upon evenings which follow warm, sunny 

 days ] they prefer to feed just before, or during, a shower of rain and 

 when there is a thaw after frost. On Nov. 3rd there was enough snow in 

 the woods to give the ground a speckled appearance, and yet I took over 

 a score of these moths. Favourable weather seemed to occur every 

 seventh day till Nov. 17th. The following are the species taken : 

 Scopelosoma Morrtso?ii, Grcefia?ia, IValkeri, sidus, and some others yet 

 to be determined. After rejecting imperfect specimens, I pinned no less 

 than one hundred and fifty-two examples of this genus. 



I may add that during September of this year— from the 12th to the 

 23rd — I have taken 104 specimens of Catocala, forty being concumbens, 

 22 unijuga, 8 habi/is, 6 each oi caret and itmitbetis, and lesser numbers of 

 parta, briseis, amatrix, bianca, neogama and piatrix.
