Leptaletis gfn. nov. 



Intermediate between Cartaletis Wan-., and Fiiraptychodes Warr., agreeing with 

 the former in nenralion and antennal stmcture, and with the latter in the very 

 mucli weaker build and consistenev of the wings, and in the character and variability 

 of the markings and coiouring. 



Type : Leptaletis variahllis iiutler (Aletis). 



Leptaletis pallida ^i'. nov. 



Forewiugs wliite, orange at base ; eosta and ajiical third smoky lilack, the bitter 

 witii two larger and two smaller white spots; liindwings white with a black border, 

 the inner edge of which is marked with a series of wedge-shaped projections. 



Slightly smaller than L. variabilis Butler. 



A jjair from ISierra Leone. One <? in British Museum. 



Paraptychodes gen. nov. 



(J. F'orewings triangular ; cost a straight, convex at base and before apex, which 

 is liluntly rounded ; hindmargin oblique, somewhat protuberant below apex ; inner 

 margin convex ; anal angle hardly marked ; fovea present. Hindwings small, 

 rounded; inner margin with a semi-elliptical flap, which is folded over on the under- 

 side, the space above it on the upper surface being marked with blackish scales ; 

 antennae pectinated, the pectinations stout and short ; palpi weak, porrect ; tongue 

 present; hind tibiae thickened, with two short spurs; hind tarsi short. Neuration : 

 forewings with cell two-thirds as long as wing ; the margins approximating towards 

 end ; discocellular irregular in shape ; first median uerviile at three-fourths ; second 

 at seven-eighths ; third from end of cell ; lower radial fi-om the centre of disco- 

 cellular, upper from upper angle of cell : third, fourth, and fifth subcostals on 

 common stem rising a little before end of cell at the point where the .subcostal 

 nervure is bent downwards; second subcostal at seven-eighths; first at three-fourths; 

 the latter fi-ee, the second anastomosing with the stem of the other three. Hind- 

 wings : costal and subcostal approximated for half the length of cell ; two subcostal 

 nervules from upper angle ; radial from centre of discocellular ; first median at half; 

 second at seven-eighths ; third from end of cell. 



?. With wings longer and narrower ; hindmargin of forewings not protuberant 

 below apex ; antennae with short strong pectinations. 



Type : Paraptychodes tenuis Butler (Aletis). 



Butler's examples of tenuis were all ? ?, as also the type of Hampson's Jnlrn. 

 which seems identical. 



Palaeomystis gen. nov. 



Forewings ample, elongate; oosta straight in the middle, arched at base and 

 convex before apex, which is slightly and bluntly produced ; hindmargin sinuous, 

 incurved beneath apex, then bowed, and oblique above the anal angle, which is still 

 distinct. Hindwings narrow, the apex almost more falcate than that of the fore- 

 wiugs ; hindmaigin sinuous ; anal angle rounded off. I'alpi ver}' short, not reaching 

 front of face; antennae simple, thickened in S ; tongue ])resent ; hind tibiae of 

 S with four spurs. Neuration : forewings, cell half the lengtli ; discocellular
