SPHINX. 199 



to the lower third of the inner margin, with an irregular brownish 

 line near the terminal margin ; a long, decided black streak in 

 medio-central interspace, with a blackish spot on the terminal 

 margin of the medio-central nervule. Posterior wings nearly uni- 

 form blackish brown, with a faint grayish central band and a gray- 

 ish patch above the interior angle. 



Pupation. Larval transformation subterranean. The pupa is 

 dark brown, with a very short cylindrical tongue-case bulbous at 

 the extremity, and applied to the breast. 



Food-plants. Mr. Newman, of Philadelphia, found a pupa of 



this insect beneath an isolated ash tree, under such circumstances 



as to render it probable that this is one of the food-plants of the 



larva. 



Long Island; New York; Pennsylvania.

 10. S. coniferarum Abbot Sf Smith. Figured in Sm. Abb. I, pi. 42. 



Cinereous ; white beneath. Thorax with a brown stripe on each 

 side. Abdomen cinereous without bands. Anterior wings, with 

 a brown basilar, wavy line, a brown costal spot above the discal 

 spot, which is blackish ; with a crenated brown line "crossing the 

 middle of the nervules edged anteriorly with whitish. A long 

 black streak in medio-central interspace, and a shorter one in the 

 posterior, with the ends of the nervules tipped with blackish. 

 Posterior wings brown. (Abbot & Smith's figure.) 



Mature Larva. Head yellow with two black lines. Body gray, 

 with three rows of dorsal, square, dark-gray spots, one of which 

 is vascular, having a black dot at each angle, and a slender, whitish, 

 vascular line, with whitish striae between the square spots. First 

 segment with two dashes and one subdorsal on each side. The 

 larva is full grown about August 27th and Nov. 10th, which latter 

 produces an imago in April following. (Abbot & Smith.) 



Food-plants. Pinus palustris. 



Georgia; Canada.

N. B. The specimen Dr. Harris described under this name, as 

 I have ascertained from a photograph, was E. harrisii. This is 

 probably likewise identical with S. coniferarum. The discovery 

 of the larva of harrisii will remove any doubt respecting the iden- 

 tity of the insects. — B. Clemens.
