thickly covered -with very short, brown hairs, scarcely visible 

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

 lowish dots which appear slightl}- raised ; there is a dorsal streak 

 of dark green arising from tlie 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 on 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 bodj-. 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 A^ery fine brownish hairs ; tlie 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 gioss}^, 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 Theda 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
