312 NOVITATES ZOOLOGICAE XXII. 1915. 



The ratlior strong anastomosis of SC with SC'~* (quite e.xceptional in material 

 heretofore studied in this genns) is constant in the ten examples known to me. 



2. Derambila jacksoni sp. nov. 



?, 28 mm. Face ochreons-whitc. Palpns white, first and second joints with 

 brown spot at end. Vertex white. Collar with one or two blackish spots. Thorax 

 and abdomen white, the latter with a row of blackish dorsal spots. 



Wings rather narrow. — Forewing with SC anastomosing with C : strongly 

 iridescent ; white, costal margin as far as SC mixed with light brown ; lines light 

 brown, formed of vein-dots ; antemedian from SO at abont two-fifths, oblique 

 inwards, the dot on M placed at origin of M-, that on SM- at abont one-third of the 

 wing-length, preceded nearer base b}- one or two other vague brown dots on SM' ; 

 postmedian nearly as in the preceding species, the dots not quite so large, the curves 

 not quite so strong ; a further series of spots, confluent into a line (narrow bar), at 

 1 mm. from termen : discal black dot minute, terminals proportionally rather large, 

 conspicuous. Hindwing the same, except costa and first line. 



Underside white, with weak discal dots. 



Nairobi, British East Africa, August 1005 (F. J. Jackson). Type in coll. 

 Rothschild. 



Distinguished from the preceding by its rather narrower wings, forewing with 

 S(J' not anastomosing with SC-, by its minute discal dots, rather less ochreons 

 markings, absence of black antemedian dot on SO, smaller but much darker 

 abdominal spots, etc. 



Subfamily HEMITHEINAE 

 3. Victoria triplaga sp. nov. 



? , 39 mm. Face and vertex reddish. Palpus reddish, paler beneath. Antenna 

 without tuft at base; strongly bipectinate ; reddish. Abdomen dorsally purplish 

 brown, with a whiter admixture, particularly in the crests. 



Forewing with termen not markedly crenate, the bend at R' not strong ; green 

 with purplish markings : a large, circular, somewhat paler centred discal spot ; a 

 small spot at two-fifths hindmargin ; two dark-edged spots at termen, namely a large 

 one between SC and R' and obliquely crossing SC'' close to termen, a smaller from 



M'' to tornns. Hind wing with termen only slightly prominent at R' and R^ ; 



concolorons with forewing and with the same markings, but with the spot on bind- 

 (inner-) margin much more elongate, the anterior terminal much smaller, reaching 

 from R' to midway between R- and Rl 



Underside similarly but more weakly marked. 



Mhonda, Ngnrn, German East Africa. Type in coll. Rothscliild. 



As both hindlegs are lost, the generic position is not absolutely certain ; if 

 it prove to lack the proximal spurs it should be regarded as a Cheroscelis with 

 obsolete tongue. The coloration is that of C. paUinta ab. ustipennis Warr., but it 

 cannot possibly be confused with any form of that variable species. The antenna 

 is pectinated to nearly two-thirds of its length (in palliata to scarcely beyond one- 

 half), and the branches are longer than in even the male of palliata ; the hindwing 

 has the costa relatively longer, the inner margin relatively shorter; the cell-spots 

 are smaller and the number and position of the dark blotches are quite distinctive.
