NOVITATES ZOOLOQICAE XXII. 1915. 315 



I believe I have seen other examples from the Cameroons and Nigeria, bnt 

 generally in poor condition. The conspicuons white terminal dots are distinctive. 

 In albisticta Warr. the}- are more elongate and are dark-edged proximally ; hatlrala 

 Feld. is less strignlated, the hindwing more angled, the fringe with red-brown s|)ots ; 

 both have long third joint of palpus. In tandi B.-Baker {^Ann. Mag. Nat. Hist. 

 (8) xi. 570) the white spots — -not mentioned in the description — are at the l)ase 

 of the fringes, and it lacks the white hindmarginal spot of the forewing. 



10. Prasinocyma trifilifimbria sp. nov. 



c? ?, 35 mm. Face dull red. Palpus in both sexes with third joint relatively 

 short ; red above, white beneath. Vertex green, between the antennae white. 

 Antenna in S with rather long, close pectinations, decreasing rather rapidly in 

 length, ceasing at about the thirty-second joint, a longish apical part merely 

 ciliated. Thorax and abdomen green above, whitish beneath ; foreleg mostly red on 

 npper and inner sides (hindlegs in S lost). 



Forewing broad, apex moderate, termen curved ; SC free, R' very shortly 

 stalked, M' just separate ; green, about as in vermicuMria Guen., the white 

 irroration and strignlation scarcely so strong ; costal edge narrowly ochreous ; a 

 black discal dot ; a small white spot on middle of hindmargin, accompanied distally 

 by a few dark scales ; fringe proximally green, in middle white, distally reddish 



grey. Hindwing ample, inner margin long, hindmargin more strongly angled at 



E^ than in most of the genus (resembling Thalassodes) ; C shortly approximated 

 to SC near base, DC^ oblique, DC^ somewhat curved, M' very shortly stalked ; 

 concolorous with forewing ; a black discal dot ; fringe as on forewing. 



Underside paler, unmarked. 



Bitye, Ja River, Cameroons, 2000 ft., .September — November 1911. Type and 

 paratype in coll. L. B. Front. 



Differs from congrua Walk, in the shorter palpus and the tricoloured fringes. 

 The only Frasinocgma known to me which shares with it this coloration of the 

 fringe is the East African pupillata Warr., of which it is not absolutely impossible 

 it may be a local race in spite of its red face, less acute apex, and lack of the pale 

 circumscription to the dLscal dots. 



11. Prasinocyma rugistrigula ab. albinotata nov. 



Differs from name-typical rugistiigala Front {Gen. Ins. 129. p. 157) in 

 having the blackish discal marks entirely obsolete or reduced to minute specks, 

 and in developing a white spot at the middle of the hindmargin of forewing. 



Bibianaha, 70 miles N.W. of Dimkwa, Gold Coast, 700 ft., October 20, 1909, 

 S type, November 19, 1910, ? (H. G. F. Spurrell), in coll. Brit. Mus. ; Bitye, 

 Ja River, Cameroons, c? in coll. L. B. Front ; Bopoto. Upper Congo (Rev. Kenred 

 Smith), cJ in coll. Rothschild. 



Of name-typical rugisirigtda I know only, besides the type from Coomassie, 

 a c? in coll. Rothschild from AVassaw district, forty-five miles inland from 

 Sekondi, Gold Coast, so that the new form would appear to be by far the more 

 widely distributed. I suspect the two will prove to be racially distinct, but the 

 occurrence of both in the Gold Coast and my lack of extensive material and of 

 topographical information render it precarious so to treat them.
