length. A high stiff spike like black double tuft as long as the body is thick on the 

 first and third abdominal segments, and a double spike on the eighth. Length 26 to 



9. Apatela dactylina Grote. 



This species is said by Mr. Thaxter (Papilio, iii, p. 17) to feed on 



the alder and willow. 



10. Apatela sp. 



This Apatela, allied to A. oblinita, occurred on the alder September 4. 



This is in form closely similar to A. oblinita, but it has no transverse 

 " crimson-red bands," and the lateral line is not " bright yellow," as 

 described in A. oblinita by Kiley. The moth emerged May 31. 



Larva. — Head of moderate size, not so wide as the body, black chestnut brown on 

 the vertex. Body blackish brown but the setiferous tubercles and hairs reddish chest- 

 nut brown : the tubercles large and bearing often as many as twenty five setae which 

 are uneven in length, but not much over half as long as the body is thick, and under a 

 lens seem to be spinulate. The raised lateral line is reddish chestnut, concolorous with, 

 the setiferous tubercles ; thoracic legs dark brown ; under side of the body dark livid 

 brown, including the abdominal legs. Length 26-27™™. 



11. Eupithecia^ sp. 



This span-worm occurred on the alder at Brunswick, Me., late in the 

 season. 



Larva.— Body slender, tapering towards the hinder end, somewhat flattened. Head 

 small, scarcely as wide as the prothorax ; reddish-brownish-yellow, like the rest of 

 the body, which is yellowish, mixed with reddish-brown, with six well marked 

 lozenge-shaped brown patches along the back, the last one succeeded by a brown 

 line ending on the supra-anal plate, the latter moderately large, with two fleshy 

 cylindrical tubercles beneath. The surface of the body is granulated, with a few 

 scattered stiff hairs along the sides and back; the lateral ridge prominent and irreg- 

 ular. 



12. Antepione depontanata Grote. 



(Larva, Plate iv, fig. 9.) 



A fine large geometrid caterpillar, dark brown, with two silver V- 

 shaped spots behind the middle of the body, was observed July 23, at 

 Brunswick, Me. It molted about July 29 to 30, and began to pupate 

 August 12 in a rolledup leaf of the alder, becoming a pupa August 15. 

 The moth appeared May 18 of the year following. 



Larva lefore last molt.— Read small, flattened, scarcely as wide as the succeeding 

 segment, the body gradually enlarging towards the eighth abdominal segment ; sec- 

 ond thoracic segment with a large hump on each side ; four blackish small dorsal 

 tubercles on each segment ; towards the end of fifth abdominal segment a large 

 double hump, forming a high transverse ridge ; supra-anal plate large, rounded, with 

 six large piliferous tubercles on the hinder edge ; below two large piliferous tuber- 

 cles at the base of the anal legs; anal legs large and broad. Body dark brown, color 

 of a twig of the alder, with a distinct V-shaped silver spot, the base situated on the 

 hump on the fifth segment ; another similar V-shaped mark on the sixth segment ; 

 from its apex a row of silver-white dots extends to the hump on the fifth segment ; 

 along the back of the three first segments are two parallel silver-white lines. Lat- 

 eral ridge prominent, and swollen at each segment with a lateral wart. Length, 30™™. 



Fully grown ^arva.— Length, 40™™. Color and appearance the same as in the pre- 

 vious molt, but the markings are rather more distinct.
