104 THE CANADIAN NATURALIST. [March 



appearance of the Mosquito in England. Some of the observers 

 maintained that they were simply English gnats, and not the 

 genuine insect. The following is a short paragraph from " Science 

 Gossip," for January, 1869 : — " Woolwich Mosquitoes. — At 

 the Entomological Society's meeting of November 2nd, 18G8, 

 the Secretary exhibited a specimen of the so-called Mosquito sent 

 from Woolwich, which proved to be a species of Chri/sopa.^' 

 Hence it will be evident that two or three different insects have 

 been confounded together under the designation " Mosquitoes " 

 in that locality, and to none of them does the name strictly apply. 



" Guide to the Study of Insects, " by Dr. Packard. — 

 Part V. of this excellent work is out, and contains a continuation 

 of Lepidoptera. An account is given of the transformation of 

 several species ; also, two full-page illustrations of the male and 

 female and female moth, " Telea Polyphemus.^^ This. work is 

 one of the most valuable of its kind in North America ; the sub- 

 ject is treated of scientifically, yet in a popular manner. The cuts 

 are excellent ; and this number is evidently one of the results of 

 the labors of a practical and experienced Entomologist. The 

 " Guide " is invaluable for the use of schools and of agriculturists. 

 One of the ways to interest our farmers and add to their success 

 may be learnt in the pages of this work. Its perusal might make 

 them acquainted with those insects which are injurious or bene- 

 ficial to their crops, so that they might know their friends from 

 their enemies. In order to interest this class in advancing scien- 

 tific agriculture, it would be well to put such works into the hands 

 of their children at school. A. s. R. 



" The Canadian Entomologist," Toronto. — The January 

 number contains notes on Canadian Lepidoptera, by the Rev. C. 

 J. S. Bethune, Secretary of the Entomological Society of Canada ; 

 also, a list of Diurnal Lepidoptera collected by Mr. B. Billings, 

 Ottawa, In this list, under the name " Vanessa Milberti," the 

 writer states " that sixty individuals of this species had remained 

 in the pupa state in the breeding cage only four days. What 

 was the temperature of the vivarium which caused so rapid a 

 metamorphosis ? A. s. B.
