508 THE BUTTERFLIES OF NEW ENGLAND. 



enlarged at the tip. The spines are long and slender, broad at base, attenuated in 

 basal half, bluntly pointed, covered with straight spinous hairs, directed nearly at 

 right angles to the spines. 



Chrysalis. Viewed from above, the body in front of the mesothorax is nearly 

 equal, or if anything the head is slightly swollen. The ocellar prominences do not pro- 

 ject but are globular ; the front of the head, including the anterior portion of the promi- 

 nences very slightly convex. Viewed from the side, the prominences have the same 

 globular character, entirely without angles, but they project downward a little in their 

 inferior curve; mesothorax rather high, arched, the anterior curve more gradual than 

 the posterior, highest and slightly angulated in the middle of the posterior half, slightly 

 and broadly carinate along the middle line of the whole thorax. Inferior surface with 

 a long and very slight sinuosity, being straight from the base of the ocellar protuber- 

 ances to near the tip of the wings ; basal wing tubercle broadly conical, not angulated, 

 not very high ; ridge behind it rather low, but slightly elevated for the supernumerary 

 projection; a laterodorsal series of rather blunt conical tubercles, scarcely as high as 

 broad on the middle of all the thoracic, and the first to eighth abdominal segments ; 

 they are very small on the prothorax and first abdominal segment, but otherwise 

 about equal ; on the abdomen there is a suprastigmatal series of similar, though some- 

 what smaller and usually proportionally loAver tubercles, a little in advance of the 

 middle of the second to eighth abdominal segments ; and a dorsal series of minute 

 warts at the posterior edge of the fourth to sixth segments. Walls of the preanal but- 

 ton coarse, broad, not very high, considerably curved outward in the middle fourth, 

 but otherwise nearly straight, though inclined iuAvards, each terminating anteriorly in 

 a small, short, rounded tubercle; cremaster viewed from above, very short, triangu- 

 lar, bluntly rounded at tip, much broader than long, the sides extending far back, 

 the bounding walls very broad and not high; viewed laterally, it is as long as it is 

 broad at the base, equal on the basal half, beyond expanding very greatly, especially on 

 the under side ; the apical field of anal booklets is longitudinal, about three times as 

 long as broad, expanding roundly at either end ; booklets not very long, moderately 

 slender, the stem perfectly straight, roundly bent at right angles, the apex tapering to 

 a blunt point and again bent roundly at right angles. 



This is a purely American genus, comprising only two or three species, 

 and extending principally east of the great mountain chain common to the 

 two continents, from the tropic of Capricorn to 40° north latitude; one 

 species is common to the w^hole of the South American part of the dis- 

 trict and as far north as Guatemala, where it encounters a second species, 

 E. hegesia, which occurs throughout Central America and the Antilles. 

 A third species is found within the limits of the United States, east of the 

 Rocky Mountains, but is abundant only in the southern states. This 

 species certainly differs very slightly from the Central American, though 

 tliey are generally classed as distinct. I have not sufficient material for 

 proper comparison, but Dr. Gundlach has sent the description of the larva 

 and chrysalis of the Cuban species given in the note,* which feeds on 



* Lnrva in general blood-red; on the head dered white stripe just below the spiracles; 



there is a l)lack spot on the triangle, another the first thoracic segment is furnished with a 



black one above the ocelli, and a third behind pair of black antenniform clubbed processes, 



the second, yellowish white; on the body covered with bluish black bristles; the other

stripe on all but the terminal segment, with a lateral pair of black, bristly spines midway

brownish line; there is a similar black bor- inferior white stripe; there is a subventral
