36 Dr. Roxburgh's Account of 
The wingS of the male expand five or six inehes, and those of 
the female from six to eight: the following part of the description 
applies to both : 
Head scarcely projecting beyond the anterior margin of the first 
pair of wings. 
Eyes large, of a dark brown colour. 
Antenna: pectinated; of the male oval, of the female lanceo- 
late. 
Palpi four, the exterior two ascending, hairy, covering the inner 
vesicular, cream-coloured, deflected pair which hide a conca- 
vity where the mouth is generally situated in other species. 
Mouth none, nor is there any kind of proboscis or tube. 
Thorax oval, completely clothed with long fine hair, of nearly the 
prevailing colour of the wings hereafter to be mentioned. 
Abdomen oblong, (of the female much larger) composed of seven 
segments, and clothed with much long fine hair, like the 
thorax. 
Legs six, hairy, nearly equal. The tarsi with a pair of long, strong, 
incurved claws. All the articulations are much contracted. 
Wings horizontal, expanded, slightly striped in the directions of 
the tendons. Superior, or first pair, of a cream orange buff, or 
brownish colour, or a mixture of these ; first, all the anterior 
margins rather concave, beyond that much curved, and bounded 
with a beautiful light blueish gray coloured belt. Posterior (fan) 
edges somewhat concave, scolloped, and ornamented with a 
pretty broad, beautiful, circumscribed, scolloped border, of 
sometimes a darker, sometimes a lighter, colour than the rest 
of the wings ; inner or abdominal edges nearly straight. In the 
centre of each wing there is a remarkable eye, with the large 
pupil of micaceous transparency, and a beautiful party-coloured 
iris.
