JSesperia mystic, Edw. — Two eggs were deposited by a beaten female in a 

 pillbox, on the 20tli of Jane, color pale yellowish green; strongly convex 

 above, flattened below, and depressed or slightly concave in the centre of the 

 flattened portion. The surface appears smooth under a magnifying power of 

 forty-five diameters, whereas in those of Hobomok, reticulations are plainly 

 seen under a power of twenty. The egg of Mystic appears faintly reticulate 

 under a power of eighty diameters. One specimen produced the larva on 

 the 28th, the other on the 29th. 



Appearance when fresh from the egg. Length one-tenth of an inch ; head 

 large and prominent, black and shining. Body above white with a slight 

 tint of yellowish brown, which is more apparent towards posterior segments ; 

 second segment nearly encircled above with a line of black — under surface 

 white ; feet and prolegs of the same color.

 prominent, dark reddish brown. Body above pale green semi-transparent, 

 darker along the middle of the body, much paler towards the extremities ; 

 second segment edged behind with a fine line of brownish black ; on each 

 side close to under surface is a fine line of dull greenish white. Under sur- 

 face dull green with a faint yellowish tinge, feet and prolegs of the same color. 



July 26th. Length .62 inch. Head large, dull red. Body above dull 

 dark green with a faint tint of brownish red ; downy with very fine short 

 hairs scarcely visible to the unaided eye ; second segment edged as before 

 with brownish black ; a dull whitish line along each side close to under sur- 

 face. Below slightly paler ; feet and prolegs pale, semi-transparent.

 Head not large in proportion to the size of body, but prominent and much 

 larger than second segment, dull reddish brown, edged with black posteriorly,
