16. Genus: l*sciMloii< k ptis Snell. 
The only species of this genus is a delicately built butterfly, somewhat recalling the Neptis species 
in the markings. The forewing has the apex obtuse and the distal margin weakly curved; margin of the hind¬ 
wing undulate. —- Larva with a pair of rather widely separated dorsal spines on each segment from 2—1 1 
and on either side below the spiracles with a small tubercle bearing stiff bristles; the spines are strongly built 
but rather short and somewhat thickened at the tip, the first 4 distinctly longer than the rest. —• The pupa 
has a very characteristic shape, the abdomen being curved backwards and the middle of the anterior side 
strongly ventricose; the mesothorax has a sharp longitudinal ridge and a weak spine on the shoulder; seg¬ 
ments 4—7 of the abdomen are sharply keeled mediodorsally. 
Ps. coenobita F. (46 d). Both wings black, with light greenish above, white and much broader coenobila. 
beneath, straight transverse bands and small spots, the arrangement of which can be best seen from the figure. 
Larva dark green with the spines blackish, at the base blue, and with red-brown head. Pupa green, with 
the wing-cases tinged Avith milk-whitish. Sierra Leone to Angola and Uganda. 
17. Genus: l*seu«lac*raea Westw. 
The species of this genus are rare and almost all mimic to a marked degree the Danaids and Acraeids, 
especially Planemo,. As in all mimetic genera the species differ very greatly in colour, pattern and shape and 
can only be recognized as really congeneric by a study of the neuration. The most important neurational 
characters have been given above in the generic synopsis (p. 143). 
The earlier stages were unknown up to a short time ago, but have been recently discovered by Mr. 
G. F. Leigh of Durban, Natal. The three species bred by him have larvae and pupae of such different forms 
that it would perhaps be justifiable to divide the genus into subgenera. The descriptions and figures thus 
far furnished by other authors from Leigh’s material are unfortunately rather superficial and give no clue 
as to several important details; the descriptions and the figures, moreover, do not agree in all points. 
As common to all the species yet knoAvn may, however, be cited: Egg spherical, above somewhat 
flattened, with regularly arranged small protuberances, so that it is similar to a sea-urchin divested of its 
spines. — Larva with a finely branched spine at either side of the dorsum on each segment from 2—-11; those 
on the 2nd and 11th segments are usually much longer than the rest, Avhich are short and erect; head some¬ 
times with short thorns on the upper surface. — Pupa with very elongated and pointed head-part; this and 
the thorax form with the abdomen a more or less distinct angle, so that the middle of the dorsum projects 
ventricosely and the ventral side becomes somewhat concave. 
The genus occurs both on the continent and on Madagascar and the Comoros and is apparently only 
entirely absent in Arabia. j 
According to the markings the species may be divided into the folloAving groups. 
Synopsis of the Groups. 
I. HindAving at least beneath Avith sharply marked black dots or streaks at the base. 
A. Forewing on both surfaces with black basal dots. Palpus beneath (except at the tip) unicolorous 
yellow or whitish. 
a) Cell of the hindwing very short. Veins 3 and 4 of the hindwing long-stalked. Wings Avith green 
spots. Body without light spots (subgen. Chloropoea Auriv.). 1. Semire Group. 
b) Cell of the hindwing moderately long; veins 3 and 4 from the same point. Wings never spotted 
Avith green; body with light dorsal spots. 
*. H indwing with narrow, sharply defined, light-spotted marginal band, but without black streaks 
- on the interneural folds. (Acraea-like forms.) 2. Hostilia Group. 
**. Hindwing without light marginal spots, but with black streaks on the interneural folds. (Planema- 
like forms.) 3. Eurytus Group. 
B. ForeAving on both surfaces without black basal dots. Palpus beneath black with Avliite longitudinal 
stripes. 4. Lucretia Group. 
II. Hindwing on both surfaces without black basal dots, above almost unicolorous black. ForeAAdng AA r ith 
several small and three large green spots, one each in the cell and in cellules 1 b and 2. 
5. Glaucina Group. 
1. Semire Group. 
Only a single species, which differs from all others in the very small cell of the hindwing.
