African Micro-Lepidoptera. 97 



narrowly set in white, to which two slender greyish brown 

 streaks running through the white apical cilia give an eye-like 

 effect ; these streaks are bent downward at the apex, and, together 

 with a large patch of brown scales in the subapical cilia, increase 

 the falcate appearance to the wing-tip ; they are distinctly visible 

 on the under side ; cilia at the anal angle pale brownish grey. 

 Hind wings deeply emarginate beneath the much prolonged and 

 slender apex ; pale shining grey ; cilia faintly brownish tinged, 

 with a distinct brownish fuscous transverse streak running through 

 them at the extreme apex, and very near their outer points. 

 Abdomen greyish white. Legs white, spotted with brownish. 

 Exp. al. 9 10 mm.

This species is perhaps not properly referred to Poly- 

 hymno, but it is hardly advisable to create a new genus 

 for its reception at present. Its more slender hind 

 wings distinguish it from the typical form of this genus. 



STROBISIA, Clem. 

 The neuration of this genus is as follows : 



Fore wings 12 veins ; 7 and 8 from a common stem ; or 11 veins, 

 7 absent (coincident with 8) ; 2 and 3 from a curved common stem ; 

 rest separate ; 1 b furcate at base. Hind wings 8 veins ; 3 and 4 

 from a point at angle of cell ; 6 and 7 from a point ; 1 b furcate at 

 base.

 Strobisia metallica, sp. n. 



Antennce pale yellow, spotted with black on the upper side of 

 each joint. Labial palpi long, recurved, acuminate; apical joint 

 slightly longer than the second ; externally whitish, slightly 

 clouded with grey, especially on the inner side. Head greyish 

 fuscous ; face shining whitish grey. Thorax greyish fuscous, with 

 a brownish tint posteriorly. Under side pale greyish ochreous. 

 Fore wings elongate, apex depressed, apical margin scarcely 

 oblique ; bronzy brown on basal two-thirds, streaked with fuscous 

 between the metallic markings, which are as follows : first a con- 

 spicuous bright steel-blue stripe along the costa from base, de- 

 pressed and somewhat widened before the middle of the wing, 

 ending above the fold at about half the wing-length ; this stripe is
