ASH CATERPILLARS. 549 



The hind wings are dark smoky brown, lighter on the hinder margin, and crossed 

 by three parallel darker brown wavy lines. The fringes are white and marked with 

 brown on the veins. The under side of the wings is gray. The forewing is crossed 

 on the outer part by a dentate line and the oblique apical lino is partly reproduced. 

 The hind wings, which are somewhat lighter, are crossed by two dentate yellowish 

 brown lines, one a little before the middle, the other a little beyond. (Fernald.) 



18. Sphinx larva. 



A sphinx larva was not uncommon on the ash at Rangeley Lake, 

 Maine, September 5 to 10, 1887. It seems to differ from any of the 

 preceding species, and 1 therefore add the following description from 

 a living specimen which died in confinement : 



Larva. — Head large, of the usual sphinx shape, green, with a broad black lateral 

 very conspicuous band, bordered in front with whitish green. The seven oblique 

 lateral lines are bright straw-yellow, bordered above with black, the latter stripe 

 edged below (between it and the yellow stripe) with white; the first six bands are 

 united at the lower end by a broad distinct whitish band. The horn is rather large 

 and long, rough, with numerous black stout conical spines. The skin is smooth, the 

 body deep pea-green ; on the anal legs and supra-anal plate are black dots of unequal 

 size. The spiracles are orange, with a broad paler border ; the first seven are embayed 

 in the lower end of the lateral bands. From the last oblique band a pale yellowish- 

 white band connects the upper end of the oblique line with the base of the horu. 

 The thoracic legs black, with two white rings at the joints ; abdominal legs green, 

 with a black patch at base. Length, 30""™ ; longth of horn, S™"". 



With the preceding species was associated 

 a young larva, which may i^ossibly be an //ffFv^i^!75i^?^^ 

 earlier stage of the same species. The fol- ^'fii^^^^<¥'?f^§^^ 

 lowing description is from life: 



Zarra.— Head narrowing towards the apex ; edge 

 square, with conical spines, on a pale yellowish band. 

 Head and body pale green, with yellowish spots on 

 the thickened portions, either arranged in short lines 

 or scattered irregularly. Seven short broad oval, '

19. Apatelodes angelica Grote. 



According to Mr. Lintner, "eight or ten of the larvse were collected 

 at Bath (near Albany) during the early part of September, feeding on 

 ash {Fraxinus)', also by Mr. Meske, at Sharon Springs, on lilac (Syringa 

 vulgaris). When not eating they usually occurred resting on and closely 

 appressed to a twig. The first transformation to a pupa was on Sep- 

 tember 14. The larva has a marked gastropachan aspect. It is now 

 for the first time described. 



Lrtri-a.— Head subrotund, dark brown, the clypeus and two lines on the front 

 lighter brown. Body with the thoracic segments tapering ; terminal segments taper- 

 ing and flattened posteriorly ; ventral region flattened ; the anal legs projecting be-
