its inner tapering extremity situated just below the final divarication of the median 

 nervure. The three small spots in the lower three subcostal nervules are seated 

 one above the other, their inner margins on a line and nearly at right angles to the 

 costal margin; they are quadrate and increase slightly in size below, the upper one 

 being square, the lower longitudinally oblong; they are situated midway between 

 the discoidal spot and the apex of the wing. The two dots are situated one just 

 above the other in the middle of the upper median and subcosto-median inter- 

 spaces, midway between the spot in the lower subcostal interspace and the outer 

 border; the lower is slightly the larger, but not more than one-fourth the size of 

 the uppermost subcostal spot. Seated upon the submedian nervure, its centre 

 below the outer edge of the lower median spot, is a pale, powdery spot, twice as 

 long as broad and about one-third the width of the interspace; outwardly it 

 merges into the ground color; there are other pale spaces in the wing, looking 

 somewhat as if due to attrition ; especially in the cell on either side of the discoidal 

 spot, at the extreme base of the lower median interspace, and along the lower bor- 

 der of the medio-submedian interspace. Length of wing, 15'75 mm ', length of inner 

 border, 9'5 mm- ; breadth of wing across the middle, 7'25 mm -, breadth of wing across 

 outer margin, 9'5 mm -.
