New Lepidojrtera collected by Mr. T. A. Barns 153 



Belongs to the group of octogesa Druce (Proc. Zool. Soc. Lond. 

 1887, p. 672, t. 55, f. 1, Cameroons), flavibasis Warr. (Nov. Zool. iv., 

 241, Cameroons), incisa Holl. (Ent. News, iv., 60, Gaboon), and 

 meliorata Prout (Nov. Zool. xxii, 372, Gaboon), which may possibly, 

 when sufficient material is available for study, prove forms of one 

 protean species. 



19. Ereunetea acrogyra sp. nov. (pi. XVIII, figs. 3, 4). 



? , 34 mm. 



Head deep flesh-colour. Palpus with inner side paler, terminal 

 joint blackish. Antenna black. Thorax above grey with a tinge of 

 flesh-colour, beneath more flesh-colour. Abdomen above mostly orange, 

 on sides grey mixed with flesh-colour, beneath paler. Legs pre- 

 dominantly grey. 



Fore wing orange, with costal margin grey, broadly (reaching SC) 

 for basal two-fifths, then very narrowly ; apical area broadly black, at 

 costa reaching from apex inwards for nearly 8 mm., at tornus termin- 

 ating in a point at SM 2 ; its proximal edge shallowly concave between 

 DC and M 2 ; fringe grey. 



Hind wing orange, with the black apical patch small, roundish-oval, 

 reaching only from apex to radial fold, at its broadest point (between 

 SC 2 and B 1 ) only measuring 3 mm. across; fringe paler orange, grey- 

 mixed opposite the apical patch. 



Fore wing beneath orange, with the grey costal border bounded 

 by C, the apical patch predominantly purplish, bounded proximally by 

 a rather narrow deep-black band which arises behind DC 1 and B 1 , 

 continues (though tapering to a point) to SM 2 and is more deeply 

 concave in middle than the boundary of the black patch of upperside, 

 leaving free the base of cellules 3 and 4 (the latter, however, black- 

 dotted). Hind wing beneath only orange at abdominal margin, other- 

 wise grey (with slight fleshy admixture) proximally, rosy-purplish 

 distally, with a breadth of 4 mm. at costa, decreasing to less than 

 2 mm. posteriorly ; a more rosy line or narrow shade at proximal edge 

 of this border shows an outward bend behind E 1 analogous to the bend 

 of the black band of fore wing ; a small blackish celldot, which is also, 

 on close observation, traceable on upper surface. 



Mkoma Mountains, S. Urindi District, E. Tanganyika, 1,600 m., 

 July, 1919. (T. A. Barns.) 



Nearest to orientalis Prout (Nov. Zool. xxii, 370), which has, in 

 rare aberrations, the apical patch of the hind wing equally short, but
