KOVITATES ZOOLOGICAE XXII. 1915. 323 



Type of the genus : Ctenoberta ahanqa, sp. nov. 



The only known African Berta {persimilis Warr.) agrees with Ctenoberta in 

 the pectinate ? antenna, bnt cannot be removed here, on account of the rest of the 

 characters. 



29. Ctenoberta abanga sp. nov. 



S ? , 23-24 mm. Face olive-green. Palpus reddish above, pale beneath. 

 Vertex and antennal shaft white, the latter becoming less pure white distally. 

 Thorax and abdomen dorsal ly olivaceous mixed with white. 



Wings coloured quite as in Bcrta — white, marked with dirty olive-green. 



Forewing in the basal area olive-green costally and with some green snffusions 

 posteriorly (here somewhat rubbed) ; traces of a thick green line from about 

 one-fifth costa to one-fourth hindmargin ; median area not very broad (occupying 

 about middle third of costa, narrowing much posteriorly), bounded on each side by 

 two or three zigzag, partly confluent green lines, and containing interrupted green 

 suffusions ; darker green markings on and proximally to DC- form a very irregular 

 discal ocellus ; distal area green along both costal and posterior margin, and 

 containing a narrow green band and a green subterminul line, the former dentate- 

 edged (esiiecially distally), the latter dentate, both parallel with the termen, the 

 white areas which intervene slightly intersected with green at the veins; terminal 

 line green, slightly interrupted ; fringe white, spotted with green opposite the 



veins. Iliiidwing similarly but rather more clearly marked, the basal area 



whiter, the discal mark oblong, almost entirely filled in with green. 



Underside white, unmarked ; costal edge of forewing olivaceous, more broadly 

 towards base. 



Abanga River, Gaboon, October 19U7 (Dr. Ansorge). Type in coll. Rothschild. 



30. Comostolopsis sladeni sp. nov. 



C'linioslnla laesaria Fryer, Trans. Liim. Sue. Zool. xv (1) 16 (1912) (neo Walk.) (iudcscr.). 

 Comostolopsis simpler part. Prout, Lep. Cat. xiv. lljl (1913) (nee Warr.) (iiidescr.). 



S, 14 mm.; ?, 10-17 mm. Smaller than simplex Warr., c? antennal pectina- 

 tions coarser, deeper reddish. Forewing with apex less pointed, costal edge more 



reddish, postmedian line apparently more deeply sinuous, but almost obsolete, the 

 red dot which accompanies it proximally between R^ and M' larger and brighter ; 



fringe green, distally whitish. Hindwing with corresponding differences, an 



additional, but minute, red dot sometimes present at R' proximally to the 

 postmedian. Forewing beneath with costal margin and suffusions redder. 



Seychelles (Fryer, I.e.). Type in coll. Brit. Mus. 



31. Comostolopsis intensa sp. nov. 



?, 17 mm. Face narrowly deep red at upper extremity, then narrowly orange, 

 then green, fading off below. Palpus orange above, the second joint strongly 

 marked with deep red, pale beneath. Vertex green, a narrow white fillet between 

 the antennae. Antenna white at base, becoming reddish distally. Thorax and 

 abdomen green above, white beneath. 



Foretcing full green, about as in lUpparehii papiUonariii L. ; a black discal 

 dot, slightly tinged with red ; an indistinct sinuous whitish jiostmedian line about 

 2 mm. from termen ; terminal line red. Hindwing the same.
