﻿162 CLEMENS' SYNOPSIS OF 



Food-plants. — The larva feeds on a species of Plumeria. 

 Geographical distribution. — South America and Central, West Indies. 



I think it doubtful whether Cramer's Hydraspus and Medor are the same species, but 

 having no specimen of the former I am unable to determine the question. The 

 general markings of the anterior wings are very similar, but Hydraspus has three white 

 spots on each side of the posterior abdominal segments, besides the three yellow spots 

 on the basal rings. This is a peculiarity neither of the male nor female Medor of 

 Cramer. 



Prof. Poey regards his Duponchel as differing specifically from Medor of Cramer 

 and Antaeus of Drury. His figure, however, does not differ from a specimen in the 

 Acad. Nat. Sciences from Jamaica, nor from a Mexican specimen in my own collection, 

 except that the latter is much larger than either, and the subterminal line in Poey's 

 figure is more distinctly edged with white.

The third article of palpi a small terminal hook ; anterior wings slightly wavy. 



Palpi blackish brown, beneath yellowish white. Head, thorax and abdomen blackish brown intermixed 

 with gray atoms ; tegulse with a black streak, edged beneath with whitish ; abdomen with a dorsal row of 

 black spots, and three large yellow spots on each side at the base edged with black, and black spots from 

 the last to the tip of abdomen. Anterior wings blackish brown, sprinkled with grayish scales ; a grayish 

 spot at the base, with a double, angular, black line crossing the middle of disc to the upper third of inner 

 margin, and two or three serrated lines of the same hue on the middle of the nervules, and a subterminal 

 black line curving from the costa near the origin of post-apical to near the inner angle and edged anteriorly 

 rather broadly with brownish gray ; black circlets on the ends of posterior nervules, and a broad black 

 apical streak ; black streaks in medio-central and posterior interspaces, and two discal whitish spots, one near 

 the sub-median nerve and the other near the sub-costal. Posterior wings transparent in the middle, with 

 black nervules and a broad, terminal, black border, with indistinct, grayish spots above inner angle ; 

 yellow at the base. Beneath, the body is whitish, with abdominal blackish spots ; and the wings yellowish 

 toward the base.
