NYMPIIALINAE: THE GENUS EUPTOmTA. 509 



Turnera ulmifolia, and which is so different from ours that current opinion 

 seems the more reasonable. 



The butterflies of this genus are a little above the medium size, and the 

 colors of the wing are arranged in a somewhat complicated pattei'n ; the 

 basal two-fifths of the wing above is tawny colored and crossed, especially 

 at its outer extremity, by narrow black bands ; the distal portions are 

 fuhous, the outer edge nearly black, and [)rccedcd by two distant narrow 

 stripes of black, the outer of which, barely escaping the border, encloses 

 a series of small, round, black spots in most of the interspaces; beneath, 

 the fore wing repeats vaguely the pattern of the upper surface, but has 

 its apex marked with brown and hoary hues, separated by an oblique line ; 

 on the hind w'ings similar colors prevail, the hoary tint being mostly con- 

 fined to a narrow marginal band and a broad extramesial belt, most con- 

 spicuous on the upper half of the wings ; the submarginal series of 

 roundish spots of the upper surface are repeated faintly beneath. 



The species are polygeneutic, but how the winter is passed does not 

 clearly appear from the facts at our disposal ; one brood appears very 

 early and another rather late in the season ; the larvae feed on various 

 p(^lypetalous augiosperms, preferably Passiflorae, and the chrysalis hangs 

 from one to two weeks. 



The butterflies frequent open grassy tracts and the rank and tangled 

 vegetation that fringes the border of woods ; they frequently settle on 

 flowering shrubs, and, when flying, beat their wings with an irregular, 

 undulating motion, usually keeping near the ground ; Doubleday says 

 that the flight of the United States species is rapid ; Bates, however, calls 

 that of the Brazilian slow. 



The caterpillars are i-ather slender, with a small, unarmed head ; the 

 body is bright, with two longitudinal white bands on each side edged Avith 

 black, and the skin highly jjolished or glazed ; there is a pair of spines on 

 the dorsum of each segment, those of the first thoracic segment greatly 

 elongated and clubbed : there is also a substigmatal series of short spines 

 on the abdominal segments. 



whitish stripe; spiracles blaclf; legs black; scattered over the thorax ami a larger one 



prolegs black at the base, beyond rufous. behind the other thoracic tubercles; there is 



Chrysalis black, with silvery white mark- a spot behind each of the subdorsal tubercles 



ings as follows : a triangular spot at the ex- of the tirst and second abdominal segments, 



treme base of the wings, divided away from and a similar one upon the succeeding seg- 



the base of the wing into two parallel stripes ments, but in the latter case confluent with 



ending in points, and lieside the posterior of another spot behind the lateral tubercles and 



which is a rhoniboidal spot; a narrow, enclosing two black points, sometimes dis- 



oblique band crossing the middle of the tiuct, sometimes merged in the ground color; 



wing, irregular in breadth, enclosing a black all the silvery spots on the posterior three 



spot and extending over the abdomen as a rings are nearly confluent above ; the last seg- 



stigmatal band as far as the penultimate seg- ment has no markings, excepting sometimes 



ment ; dots on either side of the front, one a ferruginous lustre on the borders ; spiracles 



on the occiput and one behind each of the black; tubercles golden, 

 prothoracic tubercles; there are other dots
