278 THE CANADIAN ENTOMOLOGIST. 



I think it quite possible tliat when the larva hibernates there may be 

 a fourth moult, and it is probable that those of mine which completed 

 their changes in one season had their stages hastened by being reared 

 under more southerly conditions. Several of my larvae fed comparatively 

 slowly after third moult, as though trying to hibernate, but most of them 

 died. The last was sent to Dr. Fletcher to see if he could carry it over 

 the winter successfully, but it perished. 



There can be no doubt of the accuracy of my observations, as I had 

 only a few larvte, which were under constant observation, and I preserved 

 the cast faces, which give measurements as follows, according to the 

 micrometer eye-piece of my microscope : 8, 12)^, 183^, 28. These 

 reduced to millimetres and decimals are as follows : .666, 1.041, 1.542, 

 ^■S?)3- As the faces were not of the same individual, but were simply 

 taken at random from all those preserved,' the measurements come as 

 close to the theoretical progression as is to be expected. 



I wrote to Mr. Willing to ask if he had ever noticed a second flight 

 of Epipsodea at Calgary, as I thought it possible that there "might be at 

 least a partial second brood, but he replied that he had never noticed any 

 such flight. Finding my experience so different from that described by 

 Mr. Edwards, I consulted all the literature at my command to see if I 

 could obtain any light on the questions of the normal number of ribs in 

 the eggs and of moults in the larvae of this genus, but with absolutely no 

 success. 



AELLOPOS TITAN (Cram.). 



In the Canadian Entomologist, Vol. XXIII., p. 41, Mr. Moffat 

 records the capture of the above rare moth at Grimsby, Ont., and adds 

 that it is possibly the only Canadian specimen in the country. 



Another Canadian specimen of this visitor from the tropics was 

 taken about four years ago at Gushing, P. Q., a village in the Ottawa 

 Valley, not far from Lachute. 



This specimen is now in my collection, and seems to be unusually 

 large, expanding 2.6 inches. The discal spot of primaries is quite dis- 

 tinct. The transverse straight, whitish band only extends half across the 

 wings, and consists of three rectangular spots, and the submarginal band 

 consists of five large lunules. The terminal space is slightly paler than 

 the rest of the wing, and there is no trace of the spots or bands.
