The larva, which is of a bluish green colour, feeds on Hickory, Walnut, Butternut, 

 and sometimes on Beech and Oak, and closely resembles that of polyphemas, from which 

 it may be distinguished by its having a pale yellow lateral stripe, bands of tlie same 

 between the segments, and a brown V-shaped mark on the terminal segment. 



For fuller details, we refer our readers to Mr. Rogers' excellent paper. 



Deilephila Chamceneiui and Lineata. 



Both these members of the Sphinx family are found more or less plentifully in nearly 

 all portions of the Provinces of Ontario and Quebec ; fineata, as far as we have been able 

 to learn, is more abundant in Ontario and chumwnerii in Quebec. They are both very 

 handsome moths, and so strong and active when on the wing that it is difficult to capture 

 them without injury. About twilight or a little later their period of activity liegins, 

 when they may be seen flitting about with spectre-like rapidity, hovering like the hum- 

 ming bird over flowers, into which their long and slender tongues are inserted in search 

 of the nectar there stored. 



In both the ground colour of the fore wings is of a rich green- 

 ish olive, crossed about the middle by a

pale buff' stripe or bar, extending almost 

 the whole length to the tip, while along 

 the outer margin there is another band or 

 stripe nearly equal in width, but of a dull 

 ashy colour. The hind wings are small, 

 with a wide rosy band, which covers a 

 large portion of the vnng, while above and 

 below, the colour is almost black, the hinder 

 margin being fringed with white. In the 

 markings on the bodies they also resemble 

 each other very much. There is a line of 

 white on each side, extending from the 

 head to the base of the thorax, 

 and other less prominent long- 

 itudinal lines of white on the 

 thorax. The abdomen is of 

 a greenish olive, having a 

 reddish hue on the sides 

 and spotted with white and 

 black. 



There are differences, how- 

 ever, which would enable the 

 most casual observer to separ- 

 ate them without difficulty. 

 There is a difference in size, 

 liiicata (Fig.5) beingthe largest, 

 measuiing when its wings are 

 spread about three and a half 

 inches, while chanuKntrii (Fig. 

 i) rarely exceeds two and three-quarter inches. The central band on the fore wings in 

 c/mmciMcrii is wider and more irregular, but the most striking point of difference between 

 the species is that the veins of the fore wings in lineata are distinctly margined with white, 

 a character entirely wanting in cJiamKiurii. These differences will be readily appreciated 

 by reference to the figures. 



In our Keport for 1874, we gave a short description of Z>. lineata, known also as "the 

 white lined morning sphinx ; " but since some of our readers may not have access to that 

 report, we have reproduced some of the figures then used. The beautiful figure of D. 

 Chamtencrii has been drawn and engraved expressly for this report.
