1514 THE BUTTERFLIES OF NEW ENGLAND. 



Comparative Zoology has both its eyes ornamented with the projecting 

 pollinia of an orcliid. One observed by Morrison had symmetrical 

 notches in the costal margin of tiie fore wings, indicating an injury in the 

 pupal state. Tiie buttei-fly hugs the ground when on the wing and its 

 flight is not so vigorous as that of its allies, nor does the butterfly struggle 

 so violently when captured ; indeed the male is not so strong as the female 

 of the other species. When at rest the wings are flatly expanded, the 

 costal edges of the fore wings at right angles to the body, their inner 

 margin reaching the middle of the costo-subcostal interspace ; the antennae, 

 viewed laterally, are, in general, parallel to the body, arched a little through- 

 out their course, and at the tip bent at right angles ; viewed from above, 

 they diverge at an angle of 85°, the tip of the club curving downward and 

 a little outward. 



Desiderata. Especial search should be made for the early stages of this 

 insect, which are imperfectly known. Its western distribution is unknown, 

 but the widely separated localities at which it has been taken indicate a very 

 extended range. What odor, if any, is given off" from the hind tibial 

 pencil of hairs of the male ?

Imago (58 : 3). Head moderately large, clothed with hairs of varying lengths, some 

 quite long and these arranged to some extent in transverse rows ; outside the base of the 

 antennae a curving tuft of long, nearly equal, spreading hairs, reaching fully one- 

 third way over the circumference of the eye; front uniformly and but slightly tumid, 

 projecting greatly and especially below, beyond the front of the eyes; front margin 

 gently convex and rather heavily emarginate, the sides well rounded oflT anteriorly, 

 reaching the outer edge of the antennae ; scarcely twice as broad as long and sepa- 

 rated from the vertex by a slight sulcation a little in advance of the middle of the 

 antennal bases ; vertex as broad as the front, separated from the occiput by an arcuate 

 line, scarcely tumid, but with an obscure, transverse, median, slightly arcuate ridge, 

 curving in an opposite direction to the hinder border, the whole vertex slightly and
