124 TERACOLUS. 



more or less strongly marked ; the black disco-cellular spot large. Secondaries witli 

 the central area whitish, the base, costal and hind margins brownish-black, the hitter 

 very broad, relieved by faint streaks of white, and united to the costal border by 

 a narrow brownish line, thus enclosing two white hastate spots near the posterior 

 angle; a dusky shading visible along the inner margin. 



Uiuk'nide. — Costal and discal areas of tlie i:>rimaries white ; the apical area 

 brilliant orange, surrounded by a greenish-yellow shading ; the blackish-grey marking 

 along the inner margin strongly indicated ; the nervules terminating in minute 

 black dots on the hind margin. Secondaries with the discal area whitish ; the 

 basal area and hind margin yellowish-buif, a nearly complete discal line uf orange 

 traversing the wing ; the orange costal streak and discoidal spot strongly pro- 

 nounced. 



Expanse 1'4 inches. (Sjjcc. ex Henga, West of Lal-e Nyasa, Jannurij 30, 1895;

" Dry-season " form of Male. — Very similar to the " dry-season " form of 

 2'. palie/te {fig. le), but with the black hind-marginal border rather more strongly 

 pronounced and terminating in a black spot above the first median nervule ; 

 the inner marginal line indicated by a grey shading which is almost obsolete. 

 Secondaries not differing from those of 7! paUene. 



Underside. — Similar to that of T. pallene (fig. If), the secondaries showing no 

 specklings over the sand3--pink ground-colour ; the nervules terminating in minute 

 black dots on the hind margin, and the discoidal spots very small. 



Expanse 1"3 inches. {Spec, ex Ni/asa Land; Consul Alfred Slimpe ; Mus.

Habitat. — Nyasa Land and Lake Tanganyika.

According to Dr. Butler, no " intermediate " forms of this species are yet known, 

 nor has the " dry-season " female been recognised. 



2\ infuinatus, at the first glance, resembles the West African T. evippe, but on a 

 closer inspection some ajiparently distinctive characters can be detected, and I there- 

 fore follow the opinions of Dr. Butler and Prof. Aurivillius in keeping this form 

 distinct ; and Mr. Guy Marshall is also of the same opinion. 



The last-named gentleman writes : " This is a very distinct little species, of which 

 there are two males and two females in the British Museum, from Lake Tanganyika 

 and Lake Nyasa. The general pattern of tlic black markings in the male is not 

 unlike that of a very heavily-marked 7'. ncliine (Cram.), but the apical patch is dis-
