THE BUTTERFLIES OF NEW ENGLAND. 



streaks in the interspaces between tlie middle subcostal and lower median nervules; in 

 tlie lower snbcostal it lies midway between the mesial scries and the outer border of 

 the wing; in the subcosto-median it is considerably nearer the former; below this it 

 is about in the middle of the interspaces it occupies ; the outer edge of the wing is 

 as in the fore wings except in not being so broadly edged with pink in the ? as there. 

 Fringe of both wings ashy pale, often somewhat intermingled with brownish black, 

 especially on the apical half and sometimes with the base partly covered with pink 

 scales. 



Abdomen yellow above, black at extreme base where it is covered with long, greenish 

 hairs and often along a not very narrow dorsal line; beneath yellowish white. Pro- 

 longation of eighth abdominal segment of the male (35 : 1, 2) making the upper sur- 

 face of this segment neai'ly equal in length to the tliree preceding taken together, 

 reaching backward to the tip of the clasps. Hook of upper organ slender but deep, the 

 inferior edge broadly but roundly excised before the pointed tip. Clasps twice as long 

 as broad, the upper tooth larger than the posterior and curving much more strongly 

 inwards; interior finger expanding as it curves inward and backward, but appressed, 

 the prickles slightly larger at their distal extremity and as long as the breadth of the 

 finger.

Specimens from Cuba are smaller than those from Florida and Texas. 



Accessory sexual characteristics. The mealy bordering to the upper surface of 

 the wings found only in the male (44 : 5-6) has been described above. Specimens col- 

 lected in Florida agree in general with those from the northernmost point at which the 

 species has been taken alDundantly (Long Island, N. Y.), in having a slender extension 

 of this band along the inner border nearly to its middle, narrowing as it passes toward 

 the base ; in all the subcostal interspaces the patches (always sepai'ated from each 

 other lay the nervures) often extend almost to their very base, leaving but a narrow, 

 free space between the patches and the nervures ; this is especially the case iu those 

 interspaces which open upon the costal margin ; in tlie lowest subcostal interspace the 

 patch almost invariably extends half-way to the cell, sometimes close up to it. 



The scales which occur here (46 : 33) differ from those about them in their triangu- 

 lar form, coarser striation, well rounded and entire apical margin, and, what gives 

 them donl)tless their peculiar appearance, their slight elevation, as is sliown in pi. 44, 

 fig. 6. Apparently, however, these scales have no perceptible odor; this is not the case, 

 according to Miiller, with the scales (46 : 32) found iu what might be termed the 

 Rhodocerid patch, at the extreme base of the costal border of the hind wings, above, 

 where the scales are of a more delicate shape, more regularly long-oval, but with pre- 

 cisely similar striation and texture ; both are to be regarded as androconia. Hagen 

 says the latter patch is only present in specimens from Florida and not in those from 

 Texas, but I suspect the scales will be found alike in all. 



Egg (65 : 30). Broadest in the middle where it is very broadly rounded, the curve 

 scarcely increasing toward the apex, which is truncate aud al)out an eighth as broad 

 as the middle, and rapidly increasing at the extreme base where it is broadly rounded 

 and less than one-third tlie diameter of the middle. Longitudinal ribs about seventeen 

 in number in the middle, where they are .1 mm. apart, very thin, sharp, slightly ele- 

 vated and straiglit ; the transverse lines which break the interspaces into cells 

 average in the middle of the egg rather more than twice as broad as long and are about 

 .08 mm. in distance apart, broader and less sharply defined than the vertical ribs and 

 apparently impressed ; the surface is entirely smooth and the color a uniform yellow.
