174 O^NONYMPHA PAMPHILUS. 



Pupa a little more than three eighths of an inch in 

 length, smooth and plump, very slightly ridged or 

 keeled on the back of the thorax, the superior margins 

 of the wing-cases project on each side as a rather 

 sharp ridge; the head rather square in outline, the 

 back of abdomen bent round in a curve to the anal 

 tip. 



Colour a delicate pale rather yellowish-green, with 

 a faintly darker green dorsal stripe, the edge of the 

 projecting wing-covers on each side whitish, outlined 

 with a streak of reddish-brown ; the abdomen freckled 

 very delicately with paler green ; the tip of the anal 

 point, with a short streak of brownish red on each side ; 

 the wing-cases faintly marked with darker green 

 nervures. 



This pupa was received April 16th, 1871, from Miss 

 Pasley ; having assumed the pupa state on the 5th of 

 that month, suspended to a blade of glass.

 very voraciously. The first became a pupa on July 21st 

 and the rest within a week ; the butterflies appeared 

 between 1st and 4th of August. On August 17th 

 Mr. Fletcher wrote that he had lately seen two pairs
