.50 THE CANADIAN ENTOMOLOGIST. 



Upper surface, second to sixth segments brick red, striped transversely 

 with blue, yellow and black lines ; a few white hairs on second segment ; 

 four branching yellow spines with black tips on third and fourth seg- 

 ments ; six on fifth and sixth : seventh to twelfth segments white, with 

 a faintly marked black dorsal strip ; each segment with three transverse 

 yellow bands and two oblique black spots ; seven branching spines on 

 each segment, viz., three on upper surface white, one on side brown, and 

 one close to under surface white ; two last segments black — twelfth with 

 seven spines, five white and two brown ; thirteenth segment with four 

 white spines. Sides red, with two black bands, the lower band spotted 

 with blue. Under surface grey, striped transversely with black. Feet 

 and prolegs black. 



These larvae suspended themselves to the lid of the box in which they 

 were confined by a small button of very light pink silk, on June 18th, 

 1874, and in about twenty-four hours changed to grayish brown chrysa- 

 lids. Head with two bi-forked horns, the outer point very short : thorax 

 with an elevated keel-like ridge on top, with a small tubercle on each 

 side. At the base, below this, there is a larger tubercle, and behind it 

 another keel-like protuberance, hollowed on top ; there are six raised 

 silver ornaments on the dorsal surface, the first resembling in shape a 

 capital G ; the second is an oblong spot, and the third is a sharply- 

 pointed tubercle. The abdominal segments are furnished with eight rows 

 of tubercles ; on each side are five brown spots, decreasing in size 

 towards the posterior extremity, and below the spiracles there is a brown 

 stripe. Under surface gray, with ten brown spots. 



The first butterfly emerged from chrysalis on July 3rd, 1874, the 

 second on the 4th, the third on the 6th ; the other died in chrysalis. 



These larvae fed freely on wild gooseberry, but I do not think it is itb 

 favorite food, as these were the only larvae of f annus that I could find, 

 although I searched closely for them. Mr. Edwards informs me that 

 Mr. Scudder found the larva of /annus on Willow, and that may be its 

 principal food plant here, for faunus was very plentiful here last season 

 (1874), and if the larvae had been common on the Gooseberry I must 

 have found them, a,s I examined numbers of the bushes, finding plenty of 

 larvae of G. progne, -but only four of faunus.
