of Griswold, Manitoba, living specimens of Camonympha Liornata, which travelled to 

 Ottawa (1,460 miles) inside a letter in a small flat tin box. Two specimens were laid on 

 their sides with a green leaf between them, and when the box was opened at Ottawa, four 

 days afterwards, they flew briskly across the room to the window. Unfortunately these 

 were both males, but no doubt females would travel as well. The eggs of Colias Interior 

 take exactly one week before they hatch. The egg is much like that of Colias Philodice. 

 The young larva is lighter in colour. 



The eggs, about four dozen in number, were equally divided between Mr. W. 

 H. Edwards, Mr. Scudder and myself. We all tried them with every- kind of 

 leguminous plant we could obtain ; but all failed to get the larvae to feed. Some 

 •eggs were left upon the clover where they were laid until they hatched ; but they, 

 like the others, refused to eat, and after wandering about for two days dried up. 

 •Some were placed in a refrigerator at once upon hatching, but they fared no better than 

 the rest. It seems to me worth mentioning, however, that in one jar where young 

 larvae were confined with leaves of several plants, they all gradually congregated upon 

 the leaves of a Desmodium, and three specimens spun a small crescent of silk, somewhat 

 similar to the silken path spun by young larvae of Colias Eurytheme and C. philodice, 

 to the end of which they go to feed and upon which they retire to rest. These three 

 larvae which spun these little silken crescents also passed a tiny pellet of pink excrement. 

 They would not feed, however. The only Desmodium available was D. Canadense, a 

 hairy species, and it is possible they could not get at the leaf on account of the hairs. At 

 any rate the indications are that Desmodium is a possible food plant. A confirmatory 

 fact is that one of Mr. Scudder's larvae did exactly the same as my three, and spun its 

 little crescent upon a leaf of Desmodium. Lathyrus ochroleucus, Astragalus, Vicia, Pisum, 

 Trifolium all were refused. Mr. Scudder tells me that in Europe a species of this genus 

 feeds upon Vaccinium, and a noticeable feature of all the localities, where I have taken 

 Interior, is that bushes of this genus are abundant. Should I be fortunate enough to get 

 more larvae I shall offer them this as food. 



Chinobas Macounii. — Eggs, large, globular ; rather higher than broad, flattened at 

 top and bottom ; coarsely ribbed from top to bottom with about twenty ribs, a few of 

 which divide at the bottom ; between these are zigzag furrows crossing from rib to rib. 

 Eggs laid on 6th July hatched on 26th, the larva eating a narrow strip from the egg shell 

 round the top and then pushing its way out leaving the egg-shell almost intact. Yery 

 few of the larvae ate their egg shells. The young larvae are larger (^ inch) than 

 those of Oh. Jutta, and have the heads more hairy; there are also a few black spots 

 about the head which do not occur in Jutta. Upon the head and body of both species 

 are some curious mammiform hairs. The larvae are very sluggish, and seem to like to 

 perch upon dead leaves of grass during the daytime. 



The first moult took place about 18th August, after which the larvae were four lines 

 in length. Head round, flattened in front, greenish white, punctured, bearing on each 

 side three stripes continuous with the stripes on the body and composed of the black 

 hollows of the roughened surface ; the two upper stripes join at their tips just above the 

 ■ocelli. General colour, dull, glaucous, greenish white, with brown stripes. 



On segment 2, just above and anterior to the spiracles iB, on each side in both this 

 species and Ch. Jutta, one long thoracic bristle curved forward. Food, Carices and Grasses. 



Carterocephalus Mandan. — Two eggs were laid, 12th July, upon common lawn grass 

 {Poa pratensis) and one was squeezed from the abdomen of a dead female. The egg 

 is rather small, conically hemispherical ; rather higher than wide ; pale green. Duration, 

 10 days. The young larva is white, with black head and thoracic shield. The mature 

 larva is slender and minutely downy, pale green in colour, with a white head and six 

 narrow white longitudinal stripes. Along the body are two complete and one incomplete 

 series of curious epidermal organs in the shape of chitinous concave disks which are 

 sometimes geminate on the abdominal segments. 



Pamphila ? — Amongst the more interesting of our captures were a few 



•specimens of an exceedingly active skipper, which was found in greatest numbers upon 

 the top of "The Ridge." This insect belongs to the "Comma Group" of the genus
