﻿NORTH AMERICAN SPHINGIDiE. 137 



DEIDAMIA. 



Size moderate. The body is quite fusiform and the inclination of the sides of the 

 thorax to the head is quite abrupt. The head is small, almost impacted on thorax, 

 but not depressed ; it is compressed laterally and subtufted, the front vertical and 

 moderately broad ; the eyes small and somewhat sunken ; the labial palpi short and 

 pilose ; the tongue extends to the end of the third abdominal segment ; the antennae 

 taper at the end, slightly hooked and without the terminal seta. The thorax is thick 

 and well clothed with long decumbent hair. The abdomen is long, rather slender 

 and oblanceolate, with an exceedingly slight terminal tuft. The legs are rather 

 slender and moderately long, the anterior tibiae tufted at the sides ; the posterior with 

 two very short middle and terminal spurs concealed in the tibial hairs. The anterior 

 wings are about equal in length to that of the body, and are a little more than twice 

 longer than broad across the inner angle ; the hind margin angulated in the middle, 

 truncate at the tip, excavated from the post-apical nervule to the medio-superior and 

 angularly indented above the inner angle ; the inner margin concave. The posterior 

 wings are rounded at the tips, hind margin slightly denticulated. The submedian 

 nerve is simple at the base. Male. — Antennae ciliferous. Female. — Antennae simple.

The head is grayish brown and whitish above the eyes ; palpi reddish brown. Thorax grayish brown, 

 with a double, curved white line crossing the prothorax, edged behind with brown, and a brown sagittal 

 dorsal patch, with a short whitish line across the middle of tegulse. The abomen is dull brown above, 

 with three or four subdorsal, deep brown spots ; beneath, a dull ferruginous brown, with the hind portions 

 of the segments of a lead color. Anterior wings ash-gray at the base, in the middle and towards the tip, 

 banded with brown ; a short, obscure, brown costal streak at the base ; two brownish bands before the middle 

 united on the inner margin by blackish brown ; discal spot ash-gray ; a reddish brown band, arising on 

 the costa at the origin of post-apical nervule, convex in the middle, and retreating thence to the inner 

 margin ; the subcosto-inferior and medio-superior interspaces pale brown, as well as the portions of the 

 succeeding interspaces exterior to the band, and marked by reddish brown lunules ; a deep brown apical 

 patch encircled with white ; and a subterminal one similarly colored in post-apical interspace. Posterior 

 wings dull reddish brown, with a dusky terminal border tapering to the inner angle ; fringes white.
