96 THE CANADIAN ENTOMOLOGIST. 



Length five-eigbts of an inch. Head very small, pale brownish-white and 

 shining, drawn within the second segment when at rest. 



Body above green, of rather a dark shade, but with a tinge of yellow ; a 

 prominent dorsal crest or ridge from third to tenth segments inclusive, 

 bordered on each side by a bright whitish-yellow line, spaces between seg- 

 ments somewhat depressed. From the line bordering the crest the sides of 

 body incline abruptly downwards to the spiracles where the color is a little 

 paler. Below this the body is somewhat flattened out and bordered on each 

 side from third segment backwards with a bright whitish yellow line. 

 Second segment rather paler than the rest of body with a somewhat polished 

 surface and without markings. The two hinder segments of body are much 

 flattened. 



Under surface slightly paler, feet whitish, shining, and semi-transparent ; 

 prolegs green tipped with whitish. 



The smaller specimen diflered from the larger only in being paler and 

 duller in color, and having the yellow lines less distinct. 



The larger specimen entered the chrysalis state July 3rd, the other some- 

 what later, but both failed to produce the imago, and finally dried up so much 

 that I was unable to determine with certainty to what species they belonged. 



Thecla mopsus, Boisd. & Lee. — On the 18th of May, 1868, while beating 

 some wild cherry bushes on the Poft Stanley Railroad track, a short distance 

 from London, I obtained a small Thecla larva which very much interested 

 me. Its length was one-eighth of an inch, Head small, brownish black, 

 drawn within the second segment when at rest. Body above dull rosy red, 

 of a brighter tint along sides, with the edges of the dorsal crest paler. Body 

 sparingly covered with rather long hairs nearly one-sixth of an inch long, 

 most of them curved backwards. 



Underside dull 'yellowish, feet and prolegs of the same color. 



On the 26th May it escaped from the bos in which I thought it was care- 

 fully secured, and I saw it no more. On the 9th of June I visited the same 

 locality and secured a larger specimen. I was uncertain this time as to 

 whether I got it from thorn or cherry, as in the bush I was beating they 

 were both growing close together, most probably it was from the cherry. 



Length 0.40 in. Head small, of a shining black color, with a pale stripe 

 across the front just above mandibles; mandibles black; head drawn within 

 the second segment when at rest. 



Body above green along the middle segments, deep rose color at each 

 extremity, thickly covered with short brown hairs ; second segment rosy 

 above, greenish yellow at sides with an edging of the same color in front; 

 third segment entirely rose colored ; from third to tenth segments is a dorsal 

 stripe of rose which is wide on fourth, fifth, eighth, and ninth segments,
