African species of the Lycaenesthes group of Lycaenidae. 59 
extremity, where it suddenly ascends into a high collar, front edge 
strongly serrated, the lower extremity being deeply but shortly 
excavated and forming two strong long teeth ; cingula narrow with 
the lower extremity produced backwards into a broad process, the 
arms expand but little imtil they fuse with the tegumen, which is 
very deeply excavated at the front apex only, the cheeks being 
gradually rounded off in the front; the falces are long and strong, 
curved at right angles at near their middle, and terminating as usual 
in a talon-like hook; the furca has a short base with long, narrow 
arms receding backwards ; the penis sheath is twice cxirved, the hind 
extremity being blunt and narrow, slightly angled at a little distance 
along when it suddenly expands and is deeply curved, and hollowed 
on its upper edge, at about three-fifths it is again curved and gradu¬ 
ally tapers in an even tube, to the orifice, having a short tapered 
extremity. The cheeks of the tegumen and the fore edge of the 
harpagines are sparingly furnished with fine, long hairs.

d. Both wings with large deep orange patches and broad dark 
borders. Primaries with costa and termen broadly dark brown, the 
orange patch not rounded at the apex but of the same shape as the 
wing only smaller. Underside : both wings greyish white with the 
usual pattern of this section. The postmedian stripe is fractured, 
the third and fourth spots confluent and shifted out, fifth and sixth 
each shifted slightly in, seventh right inwards; subterminal line 
broadish and interrupted at each vein. Secondaries with the spots 
of the postmedian stripe isolated and very dark. 
JIah. Delagoa Bay; Cameroons. 
A species very near to Z. erythropoecihis, Holl., but 
the shape of the orange patch of the primaries above is 
different, and the postmedian stripes in both wings are 
different, as already described.
