between it and the t. p. line is a brownish shade ; the marginal 

 line is without dentations, and not scalloped as in Clintonii ; 

 sub-marginal space streaked with black along veins i and 2, but 

 not on veins 6 and 7 as in Clintonii; the median shade is very- 

 heavy and extends from the costa to the lower anterior border 

 of the reniform ; the reniform is brown, bordered posteriorly 

 with white, and anteriorly by the median shade ; sub-reniform 

 hardly visible. Black basal dash of Clintonii totally wanting. 

 Secondaries ; the median band is not contracted near the centre, 

 as in Clintonii ; the marginal band is very nearly twice as wide 

 as that of Clintonii^ and the separation near the anal-angle not 

 so well marked as in Mr. Strecker's figure, or in the examples of 

 Clintonii that I have seen ; but not entirely connected, as in Mr. 

 Grote's figure, Pro. Ent. Soc. of Phil., vol. 3, plate 3, fig. 4; the 

 marginal yellow spot shows but slightly ; the fringe is not as 

 deep as in Clintonii, and is much darker. Under surface; bands 

 all much wider than in Clintonii, and consequently giving it a 

 much darker appearence ; the marginal band not showing the 

 separation. This van is described from one ? taken at sugar, 

 June 1 8th, i83o. I took a ^ and ? Clintonii the same evening, 

 and another $ the following evening; those being the first and 

 and last of that species taken in this locality. Though differing 

 considerably from Clintonii, I am satisfied it is only a var. of that 

 species. I sent my type of Helene to Mr. Hy. Edwards last 

 winter, and he said he had never seen one like it, and did not 

 know what it was. On the strength of his assertion, I have 

 named and described it. 



During the past season I took two specimens of Catocala 

 Robinsoni, var. Curvata. French ; both of them were ? . 



FOOD PLANTS OF PLATYSAMIA CECROPIA. 



(From papers read before the Natural History Society of Toronto, Dec, 1880, and Dec 



1881, by Wm. Brodie.] 



The following list is compiled from researches made in the 

 County of York, Ontario, during the last 17 years. 



The finding of a cocoon on a plant is not held to be conclusive 

 that the larva fed on that plant ; all such cases, when unsupported 

 by other evidence, have been rejected. 



The plants are held to be such as a perfect female Cecropia, at 

 liberty, will select as food for her young.
