﻿142 CLEMENS' SYNOPSIS OF 



No North American representatives have been described ; vid. Cramer, III. 40, pi. 

 216, f. E. 



Group IV. 



Head conical, obtuse. Wings rather broader than in the preceding groups. Fore 

 wings slightly acuminated, but not hooked at the tips, moderately oblique, and 

 distinctly denticulated along the exterior border, which forms a well defined angle in 

 the middle. Hind wings somewhat denticulated along the exterior border, which is 

 slightly excavated towards the exterior angle.

I have not been able to find that the following species, which I found in the collec- 

 tion of the Academy of Natural Sciences has been heretofore described. It does not 

 belong properly to this synopsis, being a South American insect, but I have thought 

 it advisable, nevertheless, to include it in a note.*

DEILEPHILA Ochs. 



The body is usually stout and thick. The head moderate, prominent ; the front 

 smooth, rather broad and long, semi-elliptical; the eyes moderate; the tips of the palpi 

 level with the front ; the tongue as long or nearly as long as the body ; the antennae 

 clavate, terminating suddenly in a minute hook and seta. The thorax is thick and 

 tapers abruptly to the head. The abdomen is thick and cylindrico-conical, about 

 twice as long as the thorax and tapers rather suddenly at the terminal segments, 

 having at the tip a more or less distinct, short pencil of hairs. The wings are entire ; 

 the length of the anterior equal to that of the body, rather more than twice and a half 



• Gkoop V. 



* Head prominent, free and long ; front nearly horizontal, palpi thick with the tips obtuse and level with the 

 front ; eyes small ; tongue about two-thirds as long as body ; antennas slender, longer than thorax. Thorax 

 advanced and tapering to the head. Abdomen oblanceolate, twice as long as the thorax. Anterior wings rather 

 narrow, hind border truncate at the tip ; excavated from post apical nervule to the medio-superior, where it is 

 angulated, and thence excavated to interior angle, which is prominent; inner border deeply concave above the 

 inner angle. Posterior wings rounded at the tip, hind border excavated before the inner angle, which is rounded. 

 Spurs of posterior tibiae approximated and moderate. 



C. Voi.atica. — Head, thorax and abdomen yellowish brown, with a dark brown dorsal line on head and pro- 

 thorax and a silvery transverse stripe on the basal abdominal segment. Palpi beneath and breast pale ochreous. 

 Anterior wings pale yellowish brown, with a dark reddish brown oblique band, composed of several lines 

 extending from the costa at about the origin of subcosto-inferior nervule to the inner margin and edged toward 

 the base of the wing with a double silvery band; a short bifid reddish brown line on the base of disco-central 

 nervule, and a slender line of the same hue along the medio-superior, with a wavy brownish line crossing the 

 median veins in the middle and an irregular subterminal wavy reddish brown line, bordered exteriorly with 

 a reddish brown shade in atoms. Posterior wings reddish brown, with a pale yellowish central abbreviated band.
