MYGALESIS. By Dr. C. Aurivillius. 
pythia. grass. Papa green. Sierre Leona to Angola and Uganda. In ?-ab. pythia F. (26 b, last figure) the forewing 
has at two-thirds of the costal margin a narrow white transverse band, which reaches vein 5. Commoner 
Itarpa. than the typical female form similar to the cf. ¥-ab. harpa Karsch has a more distinct, yellowish subapical 
iris, band on the forewing than the type-form. Togoland. In ¥-ab. iris Bartel both wings have above a distinct 
violet-blue reflection. Gameroons, hinterland. 
minchini. G. minchini Heron differs from the preceding species in having the forewing even shorter and broader 
and with the distal margin straight and almost smooth between vein 4 and the hinder angle; the subapical 
band of the forewing is narrow but distinct and rather sharply defined; it reaches vein 1 or at least vein 
magnijilaga. 2; the under surface is darker than in chelys. Uganda and Ruwenzori. — ab. magniplaga Heron differs 
in the larger size of the white mealy spot in the cf; this is 13—14 mm. in length, thus almost as long 
as the cell. Ruwenzori. 
Mycalesis Group. 
The genera of this group are very closely allied and are distinguished by having three veins on the forewing 
strongly inflated at the base; these are the costal, the median and the submedian vein. 
On the under surface of the wings almost all the species agree in having the basal half usually darker and separated 
by a transverse line (the median line) from the distal half, which contains the eye-spots. 
The wings in the cf cf are nearly always distinguished by hair-pencils or mealy spots. The group is also very rich 
in species in the Indo-Malayan Region. No species, however, is common to the Ethiopian and Indo-Malayan Regions. The 
Ethiopian species belong to three different genera. 
Synopsis of the genera 
A. Eyes naked 
B. Eyes hairy. 
a. Apex of forewing not produced. 
b. Apex of forewing falcate. 
4. Genus : calesis Him. 
True Mycalesis only occcur in the Ethiopion Region. Species from Asia and Australia which have 
been referred to Mycalesis have hairy eyes and belong to other genera*). 
The larvae have two horns on the head and the body is of the normal Satyrid shape. 
The ¥¥ of the numerous species agree in neuration, wing-contour and other structural characters so 
completely that it is impossible to divide them into groups. But the pencils and mealy spots peculiar to the 
Tf present distinctions which can be utilized for forming artificial groups. Although these groups have thus 
the great defect that the position of a ¥ cannot be ascertained I nevertheless use them here in order to 
facilitate the analysis of the numerous species. In the cfcf of all the species there is in the cell of the 
hindwing above near the base of the costal margin a long hair-pencil, directed anteriorly or obliquely distad. 
Synopsis of the Groups. 
A. In the cf vein 7 of the hindwing arises much nearer to vein 6 than to vein 8 or is even stalked 
with the former." 
a. In the cf there is in the cell of the hindwing at the posterior margin between the point of 
origin of veins 2 and 3 a hair-pencil directed obliquely distad and posteriorly. Iccius Group. 
b. The hindwing of the cf without this hair-pencil. Evadne Group. 
B. In the cf vein 7 of the hindwing arises halfway between veins 6 and 8 or nearer to 8, occasionally 
somewhat nearer to 6, but not twice as far from 8 as from 6. Safitza Group. 
Iccius Group. 
The species are on an average larger than in the other groups and often have the hindwing somewhat produced 
and pointed at the anal angle. In the single known larva belonging to this group the points on the last segment are 
rudimentary, knobbed. — All the species belong to the tropical parts of West Africa. 
M. hewitsoni. Both wings above black-brown, the forewing with a blue or violet transverse band, 
often whitish at the distal side, beginning at the costal margin close behind the apex of the cell and reaching 
the hinder angle; the hindwing above with a blue or violet marginal band, which is broadest at the costal
