1308 THE BUTTERFLIES OF NEW ENGLAND. 



what; the last segment broadly roundeil at the tip and slightly but broadly flattened; 

 a very large, though but little elevated, fleshy, lateral tubercle on the middle of the 

 third thoracic segment, its posterior edge abrupt, its anterior sloping ott' gradually. 

 The body is covered with excessively short and delicate, nearly imperceptible hairs. 

 Osmateria comparatively stout. Spiracles oblong obovate, more than twice as long as 

 broad. Legs very small, short, the horny joints scarcely tapering, very little appressed. 

 Claws not large, heavily heeled at base, compressed, pretty strongly and regularly 

 curved, tapering to a fine point. Prolegs pretty large and stout, tapering a very little, 

 armed at tip with a slightly arcuate, triple row of nearly one hundred closely packed 

 booklets, the exposed portions of which are very small, short, scarcely compressed, 

 pretty strongly curved, tapering. 



Chrysalis. Long, rather slender and graceful, smooth; viewed from above, the 

 abdomen, which occupies less than two-thirds of the body, is f asiform, somewhat trun- 

 cate in front, the thorax as far forvi^ard as the basal wing tubercle equal, the sides par- 

 allel and straight, the basal wing tubercle slight, in front of which the body tapers 

 rapidly to the base of the anterior end of the prothorax and then expands as rapidly 

 with the sides of the ocellar prominences, the front between their tips deeply notched. 

 Viewed laterally, the inferior surface of the wings is strongly tumid, almost bent (at 

 an angle of about 135°) and well rounded, the anterior part of the body straight, the 

 ocellar prominences turned slightly downward, the posterior portion of the body pretty 

 broadly concave ; the anterior part of the body from the summit of the mesothorax for- 

 ward is nearly straight, inclined at an angle of about 50° with the under surface, behind 

 the highest point of the mesothorax bent sharply at an angle of about 125° and continuing 

 in a nearly straight line to the abdomen ; then bent again at an angle of about 150° and con- 

 tinuing straight as far as the tip of the fourth segment ; beyond this curving downward 

 in a broad arch, but more rapidly than the under surface so that the hinder segments 

 taper regularly aud gracefully. There is a distinct carina extending along the sides of 

 the whole body, commencing at the base of the upper carina of the ocellar prominences, 

 passing through the basal wing tubercles, taking in their course the superior edges of 

 the wings and then continuing as infrastigmatal carinae over the abdominal segments, 

 a little bent at the tip of the third segment, terminating at the tip of the cremaster; 

 it is almost equally distinct throughout. The head is flattened above and below and 

 the ocellar prominences are very large, prominent, pyramidal, trigonal, the angles 

 carinate, the exterior face long and slender, tapering on the basal half, beyond nearly 

 equal, the apex rounded, those of opposite sides divergent at an angle of about 60°, 

 occasionally of 90°, the superior face triangular, pretty regularly tapering, twice as 

 long as the medium width, rounded at the tip; the front margin between them as 

 broad as their length, itself slightly excised angularly, but when they are extremely 

 divergent the anterior carinae continue to the middle of the front and are bentjat an 

 angle to each other of about 150° ; the superior carinae extend as far as the antennae, 

 the inferior with undiminished prominence to the basal junction of the tongue and 

 middle legs. Ocellar ribbon (86 : 22-23; 87 : 24) kidney shaped, strongly curved. The 

 mesothorax is somewhat elevated, the sides not rounded but sloped at an inclination 

 with each other of a little less than a right angle, the median elevation pyramidal, 

 trigonal, all the angles lightly cariuated, the posterior face the narrowest by half. The 

 basal wing carinae are only distinct as slightly greater elevations of the lateral carinae 

 of the body and a slight tumidity above and below it. Transversely the abdomen is 

 pretty broadly rounded on the expanded portion, beyond well arched; beneath broadly 

 rounded ; the sides of the wings are scarcely full, rounded at the ventral line, the sides 

 inclined at an angle of about 70°. Preanal button obscure, terminating anteriorly in a 

 pair of approximated, very broad and short and bluntly rounded, scarcely elevated, 

 recumbent, depressed. Cremaster long, tapering rapidly, the tip docked, twice as 

 broad beneath as above, transversely quadrangular, all the edges broadly and distinctly 

 carinate, the tip of the same shape, the mass of booklets as in Laertias. Booklets 

 about^seventy-flve in number, moderately large, long and slender, enlarging regularly 

 and slightly, the outer half curved slightly, at the extremity curved strongly and pro-
