THE CANADIAN EXTOMOLOGIST. 115 



^'clock, p. m., earlier or later, I had little success. I seldom used a net, 

 preferring that a specimen should escape rather than capture it in a 

 damaged condition. 



In August and September decayed apples or pomace from the cider 

 mill, spread upon trunks of trees, will attract the late species of Catocala 

 such as cara, co7icufnbefis, (Sec, and a host of the lesser Noctuidae. 



Limenitis viisippus and iirsula are also very fond of the juice of apples. 

 I have often seen the former species feeding upon apples that were being 

 sun dried, and both may be observed around apple trees upon which the 

 fruit is over-ripe. Upon more than one occasion, by wetting my fingers 

 with apple juice, and holding them near an urstda, as it sat upon a leaf 

 above me, I have induced it to leave its perch and alight on my hand, 

 where it would remain until the last drop was sucked up. Where the 

 rarer species of this genus are found, it would seem that apple might be 

 successfully used as a bait. 



The objection to cyanide offered by Mr. Norman, in No. i, Vol. vi, 

 does not seem to me a sufiicient reason for discarding it. Although 

 cyanide certainly " renders the moths rigid," the difficulty can be over- 

 come. My Catocalas, taken in the evening, remained in the bottle all 

 night, and next morning were transferred to a close box. At noon they 

 were soft enough to spread without difficulty.
