THE CANADIAN ENTOMOLOGIST. 143 



the care with which she settled in the midst of these creatures, I thought 

 the larvae might possibly live on them. So I cut off the twig and send it 

 to you. This female is in a bag in the woods where I found her." (I 

 should say here that Miss Morton knew nothing of observations on Tar- 

 quinius by other persons. It was all new ground to her.) 



On 13th Aug. : "The female laid but a few eggs, and those on the 

 side of the bag, but I saw two more butterflies this morning, and both 

 acted just as did the first one, carefully selecting a place in the midst of 

 the plant-lice, in spite of a large black and red ant, which in great num- 

 bers was guarding the aphides. I watched closely, though I had to stand 

 in the brook, and after some time I saw them lay 3 or 4 eggs, all among 

 the aphides. I then cut off the limbs and brought them home, first bag- 

 ging the females on the spot. After brushing off the lice, I found a dozen 

 eggs, all on under side of the twigs. There were a few queer looking 

 other eggs 071 the leaves " (perhaps of the grubs afterwards spoken of,) 

 " also one small hairy larva, which I do not think can be Tarquinius, but 

 as it possibly may be, I send it." 



Leaving the letters for a little while, I will give my observations on the 

 eggs and larva spoken of. One egg had not hatched, two or three had, 

 and the shells remained, each with a hole eaten out of the top. They did 

 not look to me like Lycaenid eggs, and I thought there must be some 

 mistake about it, and that they were of some moth, or possibly Hemip- 

 terous. They were button-shaped, flat at base, lying nearly full breadth 

 on the bark and firmly set, not quite circular ; the curve at top like that 

 of Lemonias Nais, not like Lye. Fseudargiolus, the central depression 

 broad and shallow, the surface somewhat rough, with no appearance under 

 a Coddington lens of network ; color pale yellow. Now all Lycaenid 

 eggs known to me are covered with an elaborate and conspicuous lace- 

 work, or are much sculptured. And the little larvae did not look like 

 Lycaenid larvae. Rather like Tortrices, and their movements suggested 

 that. The same thing struck Miss Morton. They were slender, 

 of even thickness, each segment rounded, the body itself rounded, the 

 feet, legs and head not in the least retractile ; the hairs long and short, 

 disposed very much as in some of the Nymphalidae, say Grapta or Phy- 

 ciodes, the head as broad as body, and obovoid, but prolonged at the 

 mandibles ; on segment 2 a chithious bar ; color whitish-green. 



I wrote Miss Morton forthwith that I could see no probable Tarquin 

 eggs or larvae. However, I went in search of aphides, first visiting a
