254 New Geometridae and Dioptidae in Joicey Collection 



Face and outer side of palpus ochreous, somewhat mixed with red- 

 brown. Crown green, very narrowly white in front. Antennal shaft 

 pale ochreous. Abdomen dorsally green, only with a slight patch of 

 ochreous in the region of the anterior crests (these somewhat damaged, 

 apparently mixed of white, ochreous and red-brown). 



Fore wing with costal edge narrowly ochreous, instead of broadly 

 reddish ; terminal line and fringe similarly ochreous, but with a slight 

 irroration of dark red-brown. Hind wing with fringe corresponding to 

 that of fore wing. 



Zomba Plateau, Nyasaland, November, 1920 (H. Barlow). 



The Joicey collection has a couple of typical immunifica from 

 Gambia ; the originals were from Sierra Leone. 



5. Ghlorodrepana aequisecta sp. nov. 



$ , 30 mm. Differs from rothi Warr. as follows : — 



Fore wing with the pale costal border mottled with green ; proximal 

 green area bounded by a stronger dark line, which follows a different 

 course from that of rothi, being slightly farther than termen anteriorly 

 than posteriorly, only very bluntly bent outward at E 1 , slightly incurved 

 between the radials, bluntly prominent at E 3 , and scarcely incurved 

 posteriorly ; distal area weakly marked, terminal dots almost obsolete. 

 Hind wing with apex and termen more rounded ; red costal patch 

 rather brighter ; boundary of green area showing corresponding dis- 

 tinctions to these of the fore wing ; terminal line more interrupted 

 than in rothi. 



Both wings beneath less darkened than in rothi, the postmedian 

 band of the fore wing parallel with the subterminal, not — as in rothi — 

 more oblique. 



Bitje, Ja Eiver, Cameroons, May and June, wet season (G. L. Bates). 



6. Prasinocyna trifilifimbria Prout leucopis subsp. nov. 



$ . 34 — 37 mm. Face predominently white, leaving only a small 

 upper part (rather less than one-third) red. Vertex also with the white 

 much extended. 



Fore wing with costal edge beneath more reddish. 



Nyasaland: Zomba, May, 1920 (H. Barlow). A second, rather 

 defective $ , labelled " Nyassa (Smith)," has long stood in the Joicey 

 collection. 



P. trifilifimbria trifilifimbria, from West Africa, has, like so many
