in length. The head is horny and of a very singular form, its lower surface being convex, 

 while Its upper surface is flattened. Its sharp and formidable jaws are well adapted for 

 seizing and securing its prey. They are said to attain their full growth in J uly, when 

 they leave the water, bury themselves in the earth, where they undergo their changes in 

 a manner similar to that of Dytiscus. 



The Tiger Swallowtail (Papilio turnus.) 



Fig. 40 



This beautiful in- 

 sect has been more 

 than usually com- 

 mon in some dis- 

 tricts of our Pro- 

 vince during the 

 past year, and al- 

 ways attracts atten- 

 tion from its size 

 and its majestic 

 flight, floating 

 through the air as

 butterfly, Fig. 40, 

 measures about four 

 inches across, when 

 its wings are ex-

 pair powdered on their outer margin with patches of blue scales.

 a whitish bloom and a prominent eye-like spot 

 on each side of the fourth segment. It feeds 

 chiefly on the apple, cherry thorn and bass- 

 wood. For a more detailed description of this 

 insect we refer our readers to the report of 

 Fig. 41. our Society for 1873.

In our report for 1 872 

 we published a descrip- 

 tion of this insect which 

 is a very beautiful and 

 attractive creature in 

 the perfect or moth state 

 (Fig. 42), and a very odd 

 looking object as seen 

 in the larval condition. 

 Quite recently Dr. J ohn 

 H. Gamier, of Luck- 

 now, Ont., has written 

 us in reference to this 

 insect, which he has 

 found injuring his grape 

 vines. He found sever- 

 al of the larvae feeding 

 on a Rebecca vine, for
