140 TWENTT-SIXTM REPORT ON THE STATE MuSEUM, 



Length of larva at maturity two inches ; diameter .22 of an inch. 

 Taken at Albany, September 1st, feeding on Solidago. 



Another larva, taken on the same food-plant, September 24:th, was, 

 in all probability, the same species, although presenting a marked 

 difference in appearance from the one above described. The two 

 superior lateral stripes were in this nearly black, especially on the 

 abdominal segments, apparently resulting from the thickening of the 

 bordering lines and the extension of the interior ones over most of 

 the green ground. 



The larva, when captured, was found to have attached to its sur- 

 face a black oval parasitic egg-shell. It fed sparingly for several 

 days, when it died, and was transferred to alcohol and placed in the 

 State Museum collections.
