60 THE CANADIAN ENTOMOLOGIST. 



one field of potatoes that I examined I found on nearly every plant from 

 two to seven of them, busily employed on the leaves : their blue-gray dress 

 contrasted well with the green of the leaves, and gave them quite a 

 picturesque appearance. When disturbed, they did not attempt to fly, but 

 let themselves fall from the leaves ; however, when on the ground they 

 were active enough, and soon hid themselves under stones or lumps of 

 earth. While on the plants they appeared to be very peaceable, keeping 

 together in small groups, but on some occasions they are sad cannibals. 

 A friend of mine brought me some of these insects in a paper, and when 

 I opened it there was only one alive ; the rest of them were rather badly 

 mutilated, some had lost their legs and some were minus their heads. I 

 put them together again and the survivor immediately commenced a fierce 

 attack on one of his slaughtered relatives, and did not seem one bit the 

 worse after his strange repast. 



Diapheromera femorata. — I found this insect quite common here 

 last summer ; they do not seem to be particular in their choice of trees in 

 this locality. I found them on Maple, Linden, Oak and Butternut, and 

 early in the season I found a young one making a tour of discovery on an 

 Elm that I had sugared for moths. I found the males much more active 

 than the females, stalking up the tree when disturbed, while the females 

 either remained quiet or dropped to the ground, rarely going up the tree.

HESPERIA ILLINOIS identical with HESP. ACANOOTUS, Scudd. 



I am informed by the best authorities that under the name of Hesp. 

 " Illinois," I have merely re-described Mr. Scudder's Hesp. Acanooius, and 

 I therefore hasten to make the necessary correction. 



In comparing my supposed new species with specimens and 

 descriptions of N. A. Hesperidas, I was misled in regard to Acanootus, 

 (which I had never seen,) -by Mr. C. S. Minot's description of that species 

 on page 150, vol. iv, of the Canadian Entomologist, which will be seen 

 to differ in several important particulars from my description of what now 

 appears to be the same species. 



The majority of the females taken here also differ in the spots on the 

 primaries from the female of Acanootics, as first described by Mr. Scudder. 



The few extenuating circumstances mentioned above, do not, however,, 

 relieve me of the blame of having, with injudicious haste, re-described an 

 old established species. — G. M. Dodge, Ohio, 111.
