NOVITATES ZOOLOGICAK XXII. 1915. 373 



concavities and convexities (the latter at origin of M' and neav end of M'), and 

 final!)' running very narrowly along hindmargin for a very short distance beyond 



tornns ; the contained spot of the gronnd-colonr moderately large. Hindwin.g 



uniform yellowish white, with a continuons black distal border from costa near apex 

 to tornns, 1'5 mm. broad at first, broadening a little at apex and again between M' 

 and the fold, narrow and sinuoas-edged between, and suddenly exceedingly narrow 

 behind fold. 



Under-surface the same. 



Lake Azingo, Gaboon, December 1907 (Dr. Ansorge). Type in coll. Rothschild. 



Druce treated the S of this (from the Congo) as the S of his octogesa ; it may 

 possibly be a striking aberration or geographical form of that species, but both 

 forms certainly occur in both sexes, and they demand provisional separation. 



As ab. insnlata ab. nov. I describe a ? form iu which the black apical patch 

 of the forewing is obsolete proximally to the spot of the ground-colour, with the 

 exception of an isolated round discal spot. Two examples from Bitye, Ja River, 

 Camcroons, in coll. Rothschild. 



121. Terina circumcincta sp. nov. 



<S ? , 34-40 mm. Akin to doler/s Plotz, of which it may prove a local race. 

 On an average smaller, and differing markedly as follows : 



Thorax and abdomen black dorsal 1}'. 



Forewing with the black apical portion less obliquely edged proximally, 



consequently crossing M^ much nearer to its origin. Hindwing with the black 



apical patch somewhat broader and coutinning as a moderate (circ 2 mm.) border 

 round entire distal margin and more narrowly along inner margin to about 

 halfway. 



N5'assaland : Mount Mlanje, November 20, 1912 (type cJ), and several otiier 

 examples, November 15-23, 1912, and February 4, 1913 (S. A. Neave) ; Mlanje, 

 Boma, 2400 ft., April 26, 1910, a pair (S. A. Neave). All in coll. Brit. Mus. 



T. doleris is common from the Gold Coast to the Cameroons and in Uganda, 

 and is everywhere very constant. 



Warren {Nod. Zool. xvi. .116) proposed sinking T'erina — in which he was 

 evidently correct in merging Amnemo psyche, Ilglemera and Agirpa — to the following 

 genus. I consider the latter as provisionally distinct on account of its more robust 

 build, more hairy clothing (rongh face, etc.), and other details. 



122. Pitthea cyanomeris sp. nov. 



d", 37-43 mm. Face white, with narrow oblique black bars from base of 

 antennae, almost meeting below. Palpus black, mixed with orange at base. 

 Vertex and antenna black. Postorbital rim white. Collar orange mixed with red. 

 Thorax and abdomen above dark grey with slight i)luish admixture; pectus mixed 

 with orange; abdominal cavity narrowly edged with orange; an orange ventral 

 band, narrowing posteriorly, anal extremity not orange. 



Wings shaped almost as in famula Drury. Forewing black, less deep 



proximally, where there is a slight admixture of bluish ; a large white patch on 

 hindmargin from near base to about three-fifths ; anteriorly somewhat rounded, 

 reaching SC ; an oblique distal fascia from SC to M' or just beyond. — —Hindwing
