TRIFID.E. 315 



A curious aberration, in the cabinet of Mr. S. J. Capper, and 

 taken in the Isle of Wight, is of the pale brown of 

 A. exdamationis^ with all its markings sharply defined. 

 Another far more curious, reared by Lieut. E. W. Browne 

 at Portland, is distinctly gynandrous, its right side being 

 male, left female, having the quite distinct colours of the 

 two sexes, the simple antenna on the female side much 

 larger than the ciliated or pectinated antenna of the other, 

 while the white hind wing of the male half is much larger 

 and longer than the clouded corresponding member of the 

 female side. The apes of the abdomen in this specimen is 

 very curious ; on the right side is one of the usual harpes, 

 or claspers, conspicuously covered with yellow scales, which 

 are far more noticeable than in an ordinary male, while the 

 left side shows a half cylinder in which distinctly reposes the 

 brown ovipositor. 



This species is on the wing in July and August. 



Larva brown on the back, with the central portion of each 

 segment marked with dark brown, in the form of a diamond 

 with the points cut off; dorsal line conspicuously sulphur- 

 yellow on the dorsal plate only, while on all the other 

 segments scarcely noticeable, and chiefly at the commence- 

 ment of each as rather paler brown than the mottled portions 

 it runs through. Subdorsal line dark brownish-green, edged 

 above with wedge-shaped, buff-coloured spaces ; below it 

 the sides are blackish-green, with, immediately under the 

 subdorsal line, a fine thread of dirty whitish-green, while 

 another such fine line, but undulating and interrupted, runs 

 between it and the spiracles, and a third above the legs. 

 Spiracles black ; raised spots blackish, large, and shining ; 

 head mottled, brownish, with a large black spot on each side 

 of the crown ; dorsal plate shining black ; anal plate buff, 

 horny and conspicuous ; under surface and legs greenish- 

 drab. This pattern, which is bright and sharply defined, fades 

 as the larva becomes quite full-grown, the back being then
