16 THE CANADIAN ENTOMOLOGIST. 



month ; till then we pray your patience. "We have still several thousand pins 

 left of Nos. 2, 3 & 4. 

 C. Wallbridge, Belleville. — The specimens left by you at the Canadian Institute 

 some little time ago are the following : The large moth is the American Silk- 

 worm, or Eyed Emperor ( Telea polypTiemus) ; a full account by L. Trouvelot 

 of its habits, transformations, and the most successful mode of rearing it, is 

 contained in the American JSfaturalist^ Vol. i., Nos. 1, 2 & 3 ; there is also a 

 short notice of it, with a figure of the moth, in the Canada Farmer, 18C6, p. 

 181. The gigantic water-fly is a fine male specimen of the Horned Corydalis 

 (C. cornutus) ; its larva is commonly called a " Crawler," in the "Western States 

 a " Hellgramite," — whatever that means — and is a capital bait for bass, etc. ; 

 there is an illustration and notice of it in the current number of the Canada 

 Farmer. The smaller water-fly is a species of Perla, often found in the earlier 

 part of summer, fluttering about the banks of rivers, and settling on stones, 

 aquatic plants, or any other convenient resting-place. Its larva lives in the 

 water, generally hiding itself under stones, and feeds upon small insects ; it 

 exists through the winter, and changes to a pupa in the Spring ; before assum- 

 ing the winged state it crawls out of the water and leaves its empty case behind 

 when it fles away to enjoy its brief life in the air ; the empty shells are often 

 to be found on bridges and the margins of streams. "We shall be happy to 

 receive specimens from you at any time.
