THE BUTTERFLIES OF NEW ENGLAND. 



especially in the interspace beyond the cell iinil tlie adjoining; ones; fringe pale tawny, 

 the basal third dark brown. 



Beneath very dark slate brown, the liind wings often tinged slightly with purplish, 

 the markings of the upper surface repeated beneath, usually as livid, sometimes as 

 l)ale tawny spots ; costal border of fore wings and the whole of the hind wings dusted 

 more or less conspicuously with olivaceo-tawny, in southern localities with ferruginous 

 scales, giving often a very decided hue to the parts they occupy; edge of outer border 

 delicately traced in black ; fringe ra uch as above; hind wings also furnished with a 

 paler livid yellow or tawny, but very obscure, narrow, arcuate band of interspaceal 

 clouded spots from the upper subcostal to the submediau nervule, in the middle of tlie 

 outer two-thirds of the wing; and also with a similar small spot at the extremitj' of 

 the cell. 



Abdomen blackish brown above, toward the base covered with olivaceous hairs; on 

 the sides, especially toward the tips of the joints, heavily flecked with dull tawny ; be- 

 neath pale dingy yellowish, a little infuscated toward the base. Male appendages 

 (37 : 15) with the united hooks of the upper organ deeply hollowed at the base above, 

 longer thau the centrum, tapering throughout, the tips turned upward more than in 

 brettus but otherwise similar, and the lateral arms much slenderer, aculiform; in- 

 ferior tooth more tlian twice as high as broad or as the height of the hook. Clasps 

 with scarcely auy e.xcision of the borders, curving upward, but scarcely tapering and 

 broad at tip ; upper posterior augle bent inward to form a small, minutely spinigerous 

 lobe, besides whicli the middle of the posterior edge bears a pretty large curving 

 thorn, bent abruptly inward and curving slightly upward. 



Described from 40 ^ , 30 ? . 



Acces.Bory sexual peculiarities. The discal stigma of the male has been de- 

 scribed under the wings ; the scales contained in it consist of jointed threads with 

 rather short joints (51 : 5 c) situated iu the heart of the stigma and accompanied by 

 long, abruptly and minutely spatulate rods (5 k) ; at the tip of the stigma are found 

 some exceedingly slender, two-pronged rods (5 h) , accompanied by scales of similar 

 length, enlarging from base to the rounded apex, but exceedingly slender throughout 

 (5 i) ; at the extreme base are f ouud only large cover scales of a more or less oval form, 

 generally simple and rounded at the apex (5 a, b), sometimes laterally notched and 

 roumlly excised aud finely striate (5 e) ; in the field below the stigma are found scales 

 of varying forms with entire margins, sometimes quadrangular, two or three times 

 longer than broad (5 f), but generally very long oval, and larger in the apical than in 

 the basal half; sometimes very slender (5 g), at other times stouter (5 d). 



Comparisons. The female of this species closely resembles that of several other of 

 our raniphilidi, but may be distinguished from all with which it might be confounded, 

 excepting the species of Euphyes, by the purplish tinge of the under surface of the 

 hind wings. From E. metacomet it maybe distinguished by the greater breadth of the 

 vague extra-mesial, pale baud of the same surface; and from P. verna by the lesser 

 conspicuity of the spot in the lower median Interspace of the fore wings. 



Egg i66 : 27). The cells average .Oo.s mm. in width, and the bounding raised lines are 

 .0034 mm. broad ; within the cells tlie surface is profusely dotted with shallow punc- 

 tures, from .002 to .0028 mm. in width, near tlie summit of the egg often confluent and 

 giving the surface a wrinkled appearance ; color very delicate, pale pea green. Height, 

 5 mm. ; width, .93 mm. 



Caterpillar. First stage (73. 11). Head piceons with sparsely scattered pale hairs, 

 the sutures delicately marked, and that between the hemispheres punctate; mouth
