closed on pulling up a Pitcher Plant, I contented myself, as I did not want 

 to clear the locality, and so kill the goose that lays the golden eggs. 



This species will, I think, always be rare in collections as the diflB.cultie8 

 in the way of securing any large number are so great. It requires most 

 patient search to find them, and the root of the -plant is so small that it takes 

 two plants, at least, if not more, to nourish a single larva. They appear 

 to enter the root from the crown among the bases of the petioles of the pit- 

 chers, and when all the edible part of one root is consumed they go to an- 

 other, and I found several bored roots which had been abandoned. The 

 beautiful crimson of the moth is evidently derived from the food-plant, as 

 even the frass is red. 



The plants in the locality visited by me grow among a very spongy moss 

 and the larva? when full fed appear to leave the roots before pupating, and 

 in my breeding jars they pupated in the moss. Having provided myself 

 ■with a sufficient supply of the roots to bring the five larvae to maturity, I 

 felt that that portion of my expedition had been successfully accomplished, 

 and in the afternoon played a couple of rounds over the course of the Owas- 

 coag Golf Club with a good conscience. 



The next morning I took the train for Kittery Junction, and from there 

 the next train to Kittery Point, a very short distance, and then set out to 

 walk. Morning and afternoon I must have tramped fifteen miles, but did 

 not find a single plant of Herademn Lanatum, the food-plant of G. Harrisii, 

 and I found little except a further supply of Rhodophora Florida in the 

 flowers of ffinothera. In the late afternoon I returned to Portland, and 

 left for home by the night train, which I reached on the morning of the 

 27th. 



The five larvae duly pupated and were taken with me on the eclipse 

 expedition to Labrador. Just before leaving, the pupa which I had found 

 disclosed the imago and proved not to be a Gortyna at all. Of the five 

 pupae reared, one died, one moth was unable to emerge. I performed a 

 delicate surgical operation and removed the pupa case, but the wings would 

 not expand. One emerged and apparently hid among the moss and so 

 escaped notice and damaged itself, so only two perfect specimens were 

 secured. 



Postscript. — Mr. C. H. Young of Hurdman's Bridge, near Ottawa, 

 who has been very successful in rearing G. Appassionata during the season 

 of 1906, has favored me with the following notes through Dr. Fletcher: — 



On July 12th, he found the larvae in large- numbers in a very wet swamp 

 at the upper end of Meach Lake, Que., about fifteen miles north of Ottawa, 

 at which time they were about half grown, but were full grown by the 25th. 

 He noticed particularlv that they were found only in the large plants and 

 where the plants grew very thickly. According to Mr. Young's observa- 

 tions, the larvae leave the root of the Pitcher Plant when mature, and pupate 

 amonar the old decavincr pitchers that are at least two years old and lie out 

 among the moss. A very large proportion of the larvae found by Mr. Young 

 were attacked by a fungoid disease or by insect parasites of two species, one 

 hymenopterous and the other dipterous. 



TWO INSECTS AFFECTING RED CLOYEP SEED PRODUCTION. 

 By Tennyson D. Jarvis, Ontario Agricultural College, Guelph. 



The question of clover seed production is one of extreme interest to all 

 who have the prosperity of agriculture at heart. While the seed cannot 

 be considered as a staple money crop in most sections, the use of the plant
