CAMENA. 47 



22. Iolaus maculatus, Hewitson. Plate XXI. ? figs. 29, 30. 



Upperside. Female. — Anterior wing dark brown, with a large central spot of white 

 from the base to beyond the middle, with its base and a spot at its middle lilac. Posterior 

 wing with the costal margin, a submarginal band of spots, a spot above these, and the outer 

 margin dark brown : a submarginal line of white and some lilac spots. 



Underside white, with numerous black spots. 



Exp. 1-j^j inch. 



In the Collections of W. C. Hewitson and W. W. Saunders, from Silhet. 



I have had difficulty in fixing the true position of this very unusually marked species. It 

 bears a general resemblance to the female of Hypolyctena Phorbas. It has, however, the long 

 palpi of Iolaus, as well as the third branch from the subcostal nervure. Two examples only 

 have, I believe, hitherto arrived in Europe. 



GenilS CAMENA, Hewitson. 



Head large ; eyes smooth, the space between them prominent, thickly clothed alternately 

 with black and white hair. Palpi smooth, very erect, long ; the second joint compressed, rising 

 above the head; the terminal joint of the male as long as the second. Antenna of moderate 

 length, with numerous short joints indicated by white on the underside. Body robust. 



Anterior xoing triangular; costal margin nearly straight; outer margin slightly curved 

 outwards, shorter than the other margins ; inner margin slightly projecting near the base, 

 where it is clothed with a tuft of hair on its underside. Costal nervure extending to the middle 

 of the margin ; subcostal nervure with three branches, two before the end of the cell, the 

 third at a distance from the apex ; the discoidal cell half the length of the wing, closed by two 

 disco-cellular nervules in a straight line, — the second three times as long as the first, joining 

 the third branch of the median nervure a little beyond its base ; the upper discoidal nervure 

 leaves the subcostal before the end of the cell. 



Posterior wing with two slender tails ; the abdominal fold and anal angle clothed thickly 

 with long hair ; the costal nervure continued to the apex of the wing ; the subcostal branched 

 before the end of the cell ; the cell short, closed obliquely by nervules of equal length joining 

 the third branch of the median nervule a little beyond its base. 



The species of this genus, though nearly allied to those of Deudoryx, differs from 



them in having its eyes smooth, its antennae shorter, and in being without the distinct 



lobe of the posterior wing. It resembles nearly some of the species which compose the 



second section of the genus Myrina, but differs from them also in its smooth eyes, in
