THE CANADIAN ENTOMOLOGIST. 99 



point several times to W. R. Edwards, Esq., and proposed for the species the 

 name Edwardsii. A description in manuscript was prepared and read before 

 the London branch of the Entom. Society of Canada. Being persuaded that 

 the larva above described belonged to this insect, I delayed publishing it in 

 hopes of rearing the larva so as to give its complete history. I have taken 

 specimens of the larva for the last three seasons, but have failed each time in 

 bringing them to perfection. One year I had a very fine specimen, which 

 entered the chrysalis state, but while still fresh another larva ate a hole in ils 

 side. A second season all my specimens became diseased and dried up, 

 although great care was taken of them. Last year I succeeded in bringing 

 two into the pupa state, and thought, now surely the problem will be solved, 

 but no ! Days and weeks passed away and the imago failed to appear. 

 Thinking it possible that some specimens might be delayed in their develop- 

 ment a season they were kept over until a few days^ince, when I concluded 

 to carefully dissect one to see if the species could be made out. On lifting a 

 small piece of the enclosing shell a number of minute living ichneumons 

 escaped from the orifice. On examination the second specimen was found 

 similarly infested. I hope to succeed better during the present season. 



Of late Mr. Grote has determined beyond doubt that the falacer of Bois- 

 duval's plate is distinct from that of his text, or that the test is mainly 

 founded on a species distinct from the plate, the Thecla calanus of Westwood, 

 which is identical with the insect for which I had proposed the name of 

 Edwardsii. Canadian collectors «for whom I have named specimens will 

 please bear in mind that the name falacer must be dropped and inoraia, G. 

 & B., substituted for it, and Edwardsii changed into calanus, West. 



Thecla strigosa, Harris. — Larva found feeding on thorn (craiœ ns^, June 

 13th, 1866. Length 0.55 in., onisciform. 



Head small, greenish, with a faint tint of brown, gloBsy, with a black stripe 

 across the front below the middle, and a patch of white between this stripe 

 and the mandibles ; mandibles brownish-black. 



Body above rich velvety green, with a yellowish tinge, slightly paler 

 between the segments. A dorsal stripe of a darker shade, centered along the 

 middle segments with a faint yellowish line. Anterior edge of second segmen t 

 yellowish-brown, with a few dots of a darker shade. Body thickly covered 

 with minute brown hairs scarcely visible to the unaided eye. Dorsal crest 

 not bordered with yellow as in acadica ; sides of body abruptly inclined and 

 striped with faint oblique lines of yellowish, two or three on each segment. 

 The two last segments have a patch of yellowish on each side, making the 

 dark dorsal line appear more prominent. A faint yellowish line close to 

 under surface, from fifth to terminal segments; spiracles pale red, not 

 prominent.
