specimens of Cirrocliroa Aorls. 115 



These plumules are either of a very elongated oval form, 

 or are almost linear, with the surface of the scale, however, 

 striated, and the apex terminating in a small tuft of very- 

 fine bristles. These scales are implanted in the cups by a 

 minute bulbous base, from which extends a short, extremely 

 slender, cylindrical portion. Although, however, occurring 

 in such vast numbers, these scales are not observed when 

 the insect is at rest, or dried in a cabinet, the roughness 

 which is observed in those parts of the wings being pro- 

 duced by the usual oval scales implanted amongst them, 

 sticking up as if thrust upwards by the dense mass of male 

 plumules beneath. 



Cirrochroa Aorls, Doubleday and Hewitson Gen. J). 

 Lep. PI. XXI., fig. 1, is a handsome butterfly belonging to 

 the family Nymphalidre, inhabiting Assam, Sylhet, and the 

 adjacent parts of India, which was sent to me by Major 

 Jenkins, and of which numerous examples are contained in 

 the British Museum and Oxford collection. The male has 

 the upper side of the wings of an uniform orange colour, with 

 a narrow indistinct oblique stripe across the discoidal cell 

 of the fore wings, followed by an undulated, slightly defined 

 narrow line extending obliquely from the costa of the fore 

 wings to the anal margin of the hind ones ; the tip of the 

 fore wings is black, with a submarginal row of lunules, 

 which become nearly obliterated towards the posterior 

 angle, the outer margin being also brown. The hind wings 

 are marked beyond the middle with an oblique row of small 

 round blackish spots, the space between the third branch 

 of the median vein and the discoidal one being without the 

 spot ; these arc succeeded by two rows of narrow dark 

 lunules parallel with the outer margin, which is also dusky. 

 On the underside the markings are more varied, the ground 

 colour of the wings being paler buff, with a subcentral 

 pearly whitish bar, having an irregular inner and a straight 

 outer margin ; the tip of the fore wings is also whitish, the 

 rows of lunules of the upper side being but faintly repre- 

 sented beneath. 



The female is much more varied on the upper surface 

 than the male, the ground colour of the wings being ashy 

 buff, with all the markings of the male much darker and 

 better defined, the middle of the wing being traversed by 

 an irregular pale buff band, edged internally with an angu- 

 lated blackish line ; the outer margin of the wing and its 

 markings are also much darker. 



Of this species there are two specimens in the British
