thickly covered with very short, brown hairs, scarcely visible 

 without a magnifier ; these hairs arise from small, pale, yel- 

 lowish dots which appear slightly raised ; there is a dorsal streak 

 of dark green arising from the internal organs showing through 

 the semitransparent skin. There is a patch of dull pink, or 

 rosy color, on the anterior segments from the second to the 

 fourth inclusive ; it is faint on the second ring, and covering 

 but a single portion of its upper surface, and nearly covering 

 the dorsal crest 011 the third segment, and reduced again to a 

 small, faint patch on the fourth. On the posterior segments is 

 a much larger rosy patch, extending from the hinder part of the 

 ninth segment to the end of the body. The hinder part of 

 the ninth segment is merely tinged. On the tenth segment it 

 becomes a rather large patch, widening posteriorly. Behind 

 this the body is entirely covered with rosy red. The sides of 

 the tenth segment, close to the under surface, have a streak of 

 the same color, and there is a faint continuation of this on the 

 ninth segment. The head is drawn within the second segment 

 when at rest. The second segment is smaller than the third ; 

 there is a wide dorsal crest, or ridge, from the third to the tenth 

 segments inclusive ; behind this the body is suddenly flattened, 

 the sides suddenly sloping. The under surface is yellowish 

 green, with a few very fine brownish hairs ; the feet and 

 prolegs are greenish, semitransparent. 



"On June 29th it fastened itself to the lid of the box, chang- 

 ing to a chrysalis July 1st, which was .45 of an inch in 

 length, and its greatest width .20 of an inch. The body is 

 pale brown and glossy, with many small, dark brown or black- 

 ish dots distributed over the whole surface ; they are thicker 

 along the middle above, with a faint, imperfect, ventral stripe 

 from the seventh to the eleventh segments ; the surface is 

 thickly covered with very short, brown hairs, invisible without 

 a magnifier. The imago appeared July 13th." 



Mr. Saunders has found the larva of Thecla strigosa Harris, 

 a rare species in Canada and New England, feeding on the 

 thorn, Crataegus, July 13th. "The head is small, greenish, with 

 a faint tint of brown, and a black stripe across the front below 

 the middle, and a patch of white between this stripe and the 

 mandibles, which are brownish black above. The body is of a
