FOSSIL BUTTERFLIES. 



to Carystus, leading us to believe it more probable that we are dealing with a 

 female, whose partner was possessed of the ornament of a discal dash of spe- 

 cialized scales. The species of Pansydia are smaller than those of most of the 

 neighboring genera, but PampJiilites abdita is somewhat smaller even than Pan- 

 sydia mesogramma.

Upon a dark, uniform, probably blackish brown ground, the fore wing of this 

 butterfly was provided (in the female?) with three large spots, three small spots, 

 and two dots of a vitreous appearance, besides other light streaks or powdery 

 spots. The three large spots are probably peculiar, in their present extent, to the 

 female; they consist (PI. Ill, figs. 14, 17,) of one spot in the cell and one in each 

 of the lower median interspaces; the cellular spot crosses the cell, is sublunato- 

 quadrate, its exterior edge concave, extending from the origin of the third supe- 

 rior subcostal nervule to just beyond the second divarication of the median nervure, 

 being directed in the upper half of its course toward the base of the second 

 median nervule; the spot is narrower above than below, the upper half having an 

 outward as well as upward inclination, the lower margin straight, the interior 

 margin subsinuate, convex, reaching from midway between the base of the first 

 and second superior subcostal nervules to just beyond the middle of the space 

 between the base of the first and second median nervules. The spot in the lowest 

 median interspace is nearly or quite as large as the previous, but longitudinal 

 instead of transverse, and as broad as the interspace; excepting for a little spur 

 above on the inner side, which runs a little way toward the base, the centre of the 

 spot would lie just below the second divarication of the median nervure, but by 

 means of this slight spur the spot extends baseward half way from the second 

 to the first divarication of the median nervure ; at the outer extremity the spot 

 terminates squarely and next the lowest median nervule is two-sevenths the length 

 of that vein. The spot in the middle median interspace is much smaller, subtri- 

 angular, filling the whole breadth of the interspace, half as long again as broad,
