Exianse of wings : 52 iiini. 



One S from the Escarpiiieiit, Hritish Kast Africa, Octolier — November, 1901 

 (W. Doherty). 



The obli(|ue line is straight, not concave externally, as in P. tarsispina ; its 

 suhapical angle is small and blmit, not acute; the outer margin of forewings is 

 bulged, not straight ; and the colour differs entirely. 



97. Psilocerea nigrocumulata sp, nov. 



Forewings : reddish fawn-colour, tinged with pale brown to outer line, and 

 sparsely speckled with black ; the markings exactly as in P. tarsispina, but the 

 outer line is double with a paler central thread ; the basal line, which is marked on 

 the costa by a small grey spot, is nearer the outer line on inner margin, and indicated 

 there by a slight cluster of black specks; beyond the outer line the course of the 

 subterminal line is shown by black scales, forming blotches in the submedian inter- 

 space, between veins 3 and 4, and on both sides of vein G; fringe dee[ier fawn, with 

 minute specks of white scales at end of veins ; cell-spot black, distinct. 



Hindwmijs: with the submarginal blotches slight; a minute white spot on the 

 line at the origin of veins 3, 4. 



Underside much paler, flesh-colour speckled with black. Head and thorax 

 flesh-colom- ; abdomen paler, wliitish on anal segments, second segment with a brown 

 and black patch on dorsum. 



Expanse of wings : 44 mm. 



One ? from the Escarpment, British East Africa, March 1901 (W. Doherty). 



Taken in the same locality as the specimens of P. tarsispina recorded below, 

 but at a different season. It is therefore tjuite possible, especially considering the 

 \ariability of African insects generally, that this may be the ? of another brood of 

 P. tarsispina. A single c? from Yakusu, I'pper Congo River, which I have hitherto 

 doubtfully referred to P. tarsispina, also shows dark spots in the submarginal field 

 and a darker tinge in the basal area of both wings; this sjjecimen was taken in July, 

 and is probably referable to the present form. 



98. Psilocerea pulverosa Warr. 



The ? of this species must be rare. I'p to the present I had seen seventeen 

 examples of the species, all of which, except one, were (Jc?. Now, out of thirty-five 

 examples collected by Doherty at the Escarpment, in British East Africa, only one 

 is a ?. This differs neither in markings nor colour from the deeper-tinted <5 S ; 

 but the apical angle and that at middle of hindmargin are slightly more acute and 

 inominent. The antennae are simple, filiform. 



The synonymy of this species will be as follows : 



Psilocerea pulverosa. 



Eupsamma pidverosa Warr., Nov. Zool. I. ]>. 401. 



Psilocerea upicata M'arr., Nov. ZooL. IV. p. 98. 



Psilocerea apiciata Warr., Now ZooL. IV. p. 259. 



The species varies much in coloration. At the time I described apicata and 

 referred it to Saalmiiller's genus, its idcniitv with the type of my own genus 

 Eupsnmuia entirely escaped me.
