against the darker brown subterminal space, which is differentiated by its 

 deeper color and which it inwardly limits. Subterminal line indicated by 

 the difference in color between the subterminal and terminal spaces, the 

 latter concolorous with the rest of the wing. Hind wings pale testaceous 

 fuscous in (^ , more fuscous in $ . Beneath a common fuscous line and 

 dots ; the tint is testaceous, with fuscous powdering ; fore wings the 

  darker, with ruddy costal edge. Mass.; Me.; expanse, 32 to 36 m. m. 



Both these species are slighter bodied than the European A. tri- 

 angidum, and differ in ornamentation by the shape of the ordinary spots, 

 the conformation of the t. p. line, and the pallor of the hind wings.

NOTES ON THE LARVA OF LEUCANIA PSEUDARGYRIA, 



GlTENEE. 

 BY F. B. CAULFIELD, MONTREAL, P. Q. 



On April i8th of this season, while searching for insects on Montreal 

 Mountain, I found under a stone at the foot of a hickory tree, a larva, of 

 which the following is a description : 



Length two inches. Form cylindrical, slightly annulated. Head 

 reddish yellow, with two brown streaks, and marbled with lines and dots 

 of the same color ; semi-transj^arent, shiny, slightly bilobed, with a few 

 scattered hairs of a whitish brown color. Mandibles brown. 



Body above dirty greenish grey, with darker spots and blotches, a 

 faint white dorsal line, and another of the same color a little above the 

 spiracles ; sides light greenish grey, minutely spotted with brown, with a 

 few scattered hairs of a brown color, tipped with yellowish white, Under- 

 surface, feet and prolegs very light greenish grey. 



I placed this larva in a box with some earth, but owing to the backward- 

 ness of the season I could not find any food for it. It went under the 

 earth on April 21st, and turned to a chrysalis on April 23rd. The imago 

 emerged on May 20th, and proved to be Leucania pseiidargyria, Guen.
