THE CANADIAN ENTOMOLOGIST, 49 



accounts of the habits and economy of the various species of bees, wasps, 

 hornets, ants, &c. ; it is illustrated with three excellent full-page plates, and 

 nearly fifty accurate wood cuts. Part 4 concludes the Hymenoptera, taking 

 up the families of Ichneumons and other parasites, gall flies, saw flies, and 

 horn tails ; the remainder of the Part is occupied with the commencement of 

 the order Lepidoptera, and describes the general structure of its members, 

 the mode of rearing and preserving larvse, and the beginning of an account 

 of the family Papilionidce. In the last few pages, we observed descriptions 

 of two new species by our friend and coadjutor, Mr. W. Saunders, viz. : 

 Papilio brevicauda, from St. John's, Newfoundland, and Melitœa Pachardiij 

 taken, we believe, in this country. This pari is illustrated with upwards of 

 sixty wood-cuts. Need we again commend this invaluable work to the atten- 

 tion and support of our readers ?

Mo. Oct. Nov. and Dec. 1868, Jan. 1869. 



Since our former notice of this excellent periodical, four more numbers 

 have appeared, each one replete with interesting matter, and remarkably well 

 illustrated with Mr. Riley's carefully-executed wood-cuts. "We were mucb 

 gratified at learning from the November number that its circulation was then 

 " 5,000 per month, and increasing at the rate of 15 to 50 daily." This is as 

 it should be ; and we hope to hear that it has attained to the number of 

 10,000 before the close of the volume. We may mention again that we shall 

 be happy to supply subscribers in Canada with copies, free of both American 

 and Canadian postage, on the receipt of one dollar ; or, together with our 

 own publication, post free for $1 25. We shall willingly furnish specimen 

 numbers on application.
