 sexual armature, in the long spurs and the long cross-vein D- of the hindwing. 

 The genus connects Pmedora and Hoplistopus with Psilogramma, but does not 

 show a trace of the peculiar naked stripe of the last, which is a specialisation not 

 acquired by the common ancestor. 



22. Pemba distanti spec. nov. 



c?. Whitish grey ; a lateral spot on metanotura, a series of dorso-lateral spots 

 at the ajiices of the abdominal segments, and a mesial line on the abdomen black. 



AVings, upperside. Forewing whitish grey like thorax ; an indistinct costal 



spot at basal third, another in front of upper angle of cell, two very thin discal 

 streaks R' — M=, an oblique thin line from tip of SC* towards disc, and the fringe- 

 dots at the end of the veins brownish black, a trace of a discal band beginning at 

 costal margin before fork, convex down to W, then straight, another band parallel 

 with this and proximal of it, beginning at the costal spot, interrupted between K' 



and M'. Hindwing unicolorous, very thin brown fringe-spots at the ends of 



the veins. 



Underside grej', no markings excepting a short apical oblique line on forewing 

 and the small fringe dots. 



Tenth tergite (PI. XXVIl. f. 1.2) divided as in Psilogramma, menephron, but 

 the two processes wider apart and more strongly curved downwards ; sternite 

 (PI. XXVII. f. 3) very short, with a small round lobe at each side, mesially 

 curved upwards, ^wv-'-shaped in an apical view. Ulasper (PI. XXXV. f. 25) long 

 sole-shaped, the inner sheath, just above the triangular ventro-basal part which 

 represents the harpe, raised into a low sharp ridge (/■)• Penis-funnel (P-F) a 

 short half-cylinder, open above, the ventral edge curved downwards ; penis-sheath 

 (PI. XXVIII. f. 32) with a two-pointed short process which projects laterad. 



Length of forewing : 34 mm. 



llab. Pemba Island, East Africa ; 1 c? in coll. W. L. Distant. 



XII. DOVANIA gen. nov.^ — Typus : jwecila. 



S. Pilifer normal. Tongue well developed (length ?). Eye lashed. Palpus 

 roughly scaled like body and legs, obtuse. Antenna very strongly comjiressed, 

 setiform, hook long and quite gradual : segments ventrally not quite touching 

 one another (side-view). 8pines of abdomen numerous and small. Tibiae not 

 spinose ; spurs long, almost equal in length, long terminal one of hindtibia about 

 one-fourth shorter than the first tarsal segment ; first segment of foretarsus short, 

 little longer than second, with three stout external spines besides a smaller basal 

 one ; midtarsns without comb ; pulvillus absent ; paronychinm with one lobe on 

 each side. Wings entire ; cross-veins of hindwing strongly oblique, D- twice as 

 long as D^, this shorter than D^ ; S(!- and R' on a stalk. 



Tenth tergite simple, narrow, sharply pointed ; sternite much broader, shorter, 

 truncate, with the angles rounded (PI. LIX. f. 4). Clasper reduced, without friction- 

 scales ; harpe broad, concave, roundedly dilated dorsad at end ; inner surface smooth.
