OO PEOCEEDINGS OF THE ACADEMY OF 



daries. Four translucent ochreous spots on the primaries; the first large 

 and near the end of the cell, is of trapezoidal form, with an anjiular indenta- 

 tion upon the outer side ; the second, also trapezoidal, but less than the pre- 

 ceding', is contained within the second and third median veinlets, and situated 

 midway between the first and the outer margin ; the third, resembling an 

 irregular right-angled triangle, is aligned on the first median veiulet, with 

 the second and fourth, which last is small and obovate, placed on the sub- 

 median vein just beyond its middle ; a curved ash-gray bar, widest centrally, 

 and tapering at either eml, extends between these last spots and the cell from 

 the submedian vein to the second median veinlet, touching above the upper 

 angle of the third spot, and below the inner portion of the ovoid. 



Secondaries immaculate ; fringe ochreous yellow, lightly cut with brown ; 

 expanse 2"13 inches. 



Underneath, the primaries have an ash brown apical triangular patch, sep- 

 arated by a brown bar from an irregular purplish ashy belt, extending from 

 the margin down to the second translucent spot, and which contains a darker 

 spot near the middle of its inner margin ; the costa between this belt, and a 

 pale ochreous spot resting thereon, above the translucent spot in the cell, is 

 reddish brown ; the fourth spot of the upper surface is covered by a large 

 pale yellow ovoidal spot ; the ashy bar is wanting. 



Secondaries pale piirplish brown, with darker velvet maroon brown shades, 

 formed into three prominent areas, viz., a broad border, a large central [)atch, 

 and another resting ou and below the middle of the costa ; there are also two 

 basal bars and a series of connected lunulse between the central patch and 

 the marginal band. Antennae brown ; club ochreous beneath.

Upper surface black, with asliy shades, and waved brown lines traversing 

 the surface. Primaries : a white spot occupies the middle of the cell ; beyond 

 a mesial white band, broken into two parts, of which the lower occupies the 

 central portion of the first median interspace ; the upper extends from beyond 

 this to the costa ; on the margin, midway between this band and the apex are 

 two small white spots ; there is an indistinct series of submarginal black 

 sjiots, each having a minute wliitish or gray point, sometimes enlarging into 

 an enclosing crescent, attached to its outer exliemity. 



Secondaries : a broad mesial band, bifid on the costa ; below, a sinuated 

 irregular line ; both white ; a submarginal series of indistinct spots. Fringe 

 brown, white towards the anal angle ; expanse 1'25 — 1-5 inches. 



Below, primaries ; an oblong white dash in the cell ; the central band as 

 above ; an abbreviated series of three or four white spots run down from the 

 costa, in place of the two on tlie upper surface ; along the outer margin a 

 series of large white oblong dashes, becoming brownish towards the apex, 

 and containing each a rounded dark brown spot— in the lowest, the spot is 

 geminate. 



Secondaries white, or soiled white, more or less brown towards the base ; a 

 subcentral maculate row of brown spots, of which three or four are contigu- 

 ous, towards the abdominal margin, and two distinct ones nearer the costa ; 

 along the outer margin are connected lunula3, rarely coalescing with the spots 

 of the inner row. 



Body above black ; the rings of the abdomen marked with whitish hairs, 

 underneath white ; palpi white, excepting the terminal article, which is 

 black. Antennae brown, with incomplete white annulations, club tipped with 

 ferruginous.
