432 XOVITATES ZOOLOGICAE XXIV. 1917. 



9. Problepsis flavistigma dilatistigma subsp. nov. 



(J ?, 45-50 mm. Larger than flavistigma flavistigma Swdnh. (Tr. Eni. Soc. 

 Land. 1904, p. 564), from Sierra Leone. Hindwing with termen rather more 

 regularly rounded, ocellus expanding behind M and R', measuring 2 mm. at 

 M' (in /. flavistigma 1 mm.). 



Escarpment, British East Africa. 6,500-9,000 ft., October— November 1900, 

 January 1901 (W. Dohcrty), S type, another S, 3 ?? in coll. Tring Museum, all 

 with the lines feebly expressed, terminal line wanting ; also a more .strongly 

 marked example from Nairobi. Here belongs also Swinhoe's second <J (loc. cit.). 



Might be mistaken at first glance for a weakly marked form of aegretta , which , 

 however, was taken in the same locality in a very strongly marked form (see 

 supra). Distinguishable by the rather longer antennal pectinations (about 

 four times the diameter of shaft, in aegretta nearly three times), longer tarsus 

 (two-thirds tibia, in aegretta scarcely one-half), blacker face (lower half whitish 

 in aegretta), position of median line of forewing (well beyond the discal mark 

 instead of running to it) and almost entire absence of silvery scales at ab- 

 dominal margin of hindwing. Possibly both flavistigma and dilatistigma are 

 forms of ochripida Warr (Nov. Zool. viii. 10), from 8t. Thome, of which I 

 know only the type S, with shorter, weaker ocelli (not crossing R') and median 

 line more distally placed (on forewing mid\\ay between ocellus and postmedian, 

 on hindwing just beyond ocellus (in flavistigma crossing it)). The " Sierra 

 Leone " example cited by Warren Hoc. cit.) must certainlj- have been the 

 British Museum specimen (acquired in 1899), which later serv^ed as Swinhoe's 

 type of flavistigma, for no such specimen exists in the Tring Museum. 



10. Anacosymbia chrysoparalias spec. nov. 



(J, 26 mm. Face and uppcrsidc of palpus dull dark red ; palpus beneath 

 pale ochreous. Vertex and antenna yellowish white, the latter in places marked 

 with rufous. Collar ochreous. Thorax and abdomen mostly concolorous -ttith 

 wings, front of thorax vinaceous, abdomen dorsally mixed with dark purplish. 

 Hindtarsus as long as tibia. 



Forewing vinaceous cinnamon, strongly mixed with rufous ; costal edge 

 to about three-fourths narrowly jcUowish white ; lines dark olive-grey, almost 

 black ; antemedian rather thick, ill-defined, sinuous; median thick, well be- 

 yond the cell-spot, rather strongly sinuous, the inward bend beyond the middle 

 stronger than in albivertex 8winh. (Tr. Ent. Soc. Land. 1892, p. 15) ; post- 

 median fine, hinulate-dcntate, the hmule inward between M' and SM' deepest, 

 sUght inward bends near costa and between the radials ; cell-dot large ; a 



shghtly interrupted blue-black terminal line. Hindwing with shght olivaceous 



admixture in proximal area ; antemedian Une wanting ; median continuing the 

 antemedian of forewing, formed as in albivertex Swinh. ; postmedian formed 

 about as on forewing, continuing median of forewing ; cell-dot elongate ; 

 tcnninal line as on forewing. 



Underside pinkish bufl', slightly more vinaceous in middle of forewing ; 

 both wings with a vague pinkish grey subterminal fine, that of forewing nearlj- 

 as above, that of hindwing as near termen as on forewing ; terminal line feeble, 

 olivaceous.
