THK CANADIAN KNTOMOI.()( WS'I'. 67 



(Jn 25th July, 1 88 1, I again rt'(;ei\ed eggs from Mr. W'ui. E. Gallagher, 

 of Whitings, T-ake Co.. Ind. \\'licn 1 opened the box there were abotit 

 35 ne\\l\- hatched larva?. Another smaller lot eame from same source ist 

 Aug. From one cause or other, the most efficient being minute spiders in 

 the sod, and which I discovered only when too late. I had but 3 of these 

 larv£e on 30th Aug., all i)ast third moult. They retained their green color 

 until a few hours after that moult, then turned buff. I sent one of these 

 to Mrs. Peart, in Philadelphia. By loth Sept., both my larvae were in 

 lethargy. I recorded on iQlh Sept.. that one of them had shifted its 

 position. The same thing occurred 29th Sept.; and on ist of Oct., the 

 same uneasy larva left the grass and climbed four inches up the glass 

 cylinder which covered it. On 12th Nov.. this larva had moved again, and 

 next on 4th Dec. Meanwhile the one which had been sent to Phila- 

 delphia behaved differently, and went on to fourth moult, passing it 27th 

 Oct. One of my two died, but the other I brought into a warm room on 

 13th Feb. (temp, outside 65'), and placed in the sun. In al)Oiit fifteen 

 minutes it moved and soon after had eaten. When brought in. it 

 was much shorter and smaller than when it went into lethargy. It had 

 been .6 inch then in length, now it was less than .4 inch. By 25th Feb., 

 it had reached .5 inch, and 2nd March had fully recovered its former 

 length, .6 inch. Early in March, it began to change color, and by the 6th 

 had become green. It reached .66 inch before it passed fourth moult, which 

 occurred 24th March. The larva which had passed the winter in Phila- 

 delphia had escaped, and I sent this last survivor of the brood to Mrs. 

 Peart. It passed fifth moult 25th April, and continued to feed, by the 

 7th May becoming full grown. After which it did not increase in size, 

 seemed to be at rest all the time, and finally died 2nd July, before pupa- 

 tion. So that the egg wdiich had been laid in the middle of July pro- 

 duced a larva which had not pupated 2nd July the next year. So pro- 

 tracted are the stages in several of the Neonymph?e larvae that rearing 

 them becomes excessively tedious, the more so as during the months when 

 they are feeding they require daily looking after. 



When at rest, the Cant/nis larvc-e, as do those of all this genus, have 

 their heads turned down and under, so that the horns are nearly in same 

 plane as the dorsum, after the fashion of Apatura larvce. When feeding, 

 Cant/ius has the tails elevated at about 45°, and separated. They rested 

 much on the glass cylinder at times, especially just before and during the 

 moults, and spun for these occasions quite a web on which to support
