the end of the cell ; 5 a little neai'er 6 than 4 ; the upper discocellular nearly straight, 

 inclined inwards, the lower slightly convex inwardly ; together they are about equal 

 to half the cell-length, which is a little more than half the wing ; 3 and 4 arising 

 together at the lower corner of the cell ; and 2 at about two-thirds from the base of 

 the cell. 



Antennal club more gradual than in UranotJiauma, and about one-sixth of the total 

 antennal length. 



The subporrect palpi clothed with projecting hairs, which are about half the length 

 of the second joint; the third joint also hairy. 



The fore tarsi with an apical spine in the male and with a claw in the female. 



No sex-mark present in the type species. 



Above, the appearance of this species suggests a Scolitantides, while the underside 

 recalls the markings of the Uranothauma group, especially of U. antinorii. Following 

 the classification of Aurivillius, it would be assigned to Cii/pido in the section Cacyreus 

 Butler (proposed to replace the preoccupied Hyreus Hiibner), on the strength of the 

 underside marking and the freedom of vein 11 of the fore-wing from vein 12 ; but 

 the shape of the hind-wings, with the costa arched in both sexes (instead of being 

 somewhat sigmoid as in the males of Cacyreus), the entire absence of a tail in both 

 sexes, the very much greater separation of veins 11 and 12 in the fore-wing, and the 

 rather more irregularly cuneiform shape of the hind-wing cell — extending about half 

 the length of the wings, with a slightly inward inclination of the d;scocellulars 

 costally, — seem points sufficient to give at least subgeneric value ; and preferring to 

 treat it as generic, I propose the name llarfendyreuH for the form under discussion. 



Harpendtkeus reginaldi, sp. n. (Plate V. figs. 23, 24, s ; 25, 26, ? .) 



Greatest wing-expanse : cT 30 mm., ? 32 mm. Antennae 8 mm. 



Structure. — Fore-wing : in both sexes the costa is slightly arched ; the apex evenly 

 rounded, the costa making more than two-thirds of a right angle with the external 

 margin, which is but slightly convex ; the tornus bluntly rounded and the interior 

 margin nearly straight. Hind-wing : in the male the costa is well arched, the external 

 margin convex, and the internal margin forming a flattened curve, less arched than 

 the costal. The $ similar, but the costa a little less arched ; at vein 1 a slight non- 

 caudate projection, the tornus evenly rounded, and the internal margin slightly sinuate 

 distally. 



6. — Upperside. Fore-iving : dull blue (much discoloured, probably with a violet 

 gloss), the costal margin with a narrow edging of dark brown, the external margin 

 with a broad well-dehned border of dark brown (2 mm. wide), the cilia white with 

 brown patches at the veins. Hind-wing : with the outer brown border much broader 

 than in the fore-wing, ill-defined internally and partly suffused with lighter cinnamon 

 scaling; between veins 1 and 2 is a black ocellus, which is scaled with blue-white 

 externally and bounded inwardly by a partial ring of almost tawny scales.
