LACHNOCNEMA. By Dr. C. Auriyillius. 
Review of the Species. 
A. Tlie under surface of the forewing at the costal margin (being very broad as far as the median) and at 
the apex yellowish-brown; hind wing beneath with transverse rows of spots which are scarcely darker 
than the ground and therefore distinctly prominent only by their fine whitish bordering; sometimes 
the under surface is whitish and almost unspotted. The broadest and most distinct of these transverse 
rows is situate somewhat behind the middle and forms a complete bow between the anal angle and the 
costal margin. First tarsal joint rather narrow. 
a. Hindwing above with a black marginal band of 3 to 5 mm width, not being interrupted in the middle. 
*. Margin of forewing complete or almost complete. M. zymna. 
**. Margin of forewing distinctly undulate. M. angulosus. 
(3. Marginal band of hindwing above 2 to 3 mm broad at most, in the middle very narrow or entirely 
interrupted. M. simplex. 
B. The under surface of the forewing only at the apex somewhat darkened; hindwing beneath with 3 or 4 
irregular, dark brown transverse bands being very prominent on the lighter ground. Hindwing above 
uni-coloured white with brownish fringes or with a fine black marginal line between the veins 1 b and 5, 
or with a narrow dark marginal band. First tarsal joint much broader and more flattened. 
M. metaleucus. 
zymna. M. zymna Dbl. 6c Hew. (65 f). Costal margin of forewing above as far as the discal cell dark brown. 
pallida. Hindwing beneath light brown with very indistinct light transverse lines. Ashanti to Gabun. -—- pallida /. nov. 
A $ lyhrg before me from Ruwenzori deviates by the costal margin of the forewing being above white with small 
oblong black spots at the costal margin itself and by both wings being beneath whitish without distinct spots. 
— Lamborn describes the larva to be bark-coloured brown with a hard skin above, densely covered with stiff¬ 
haired tubercles. It partly lives on the Jassid Nehela ornata Dist. partly on Membracids of the genera Lejcto- 
centrus, Anchon and Gargara all of which are visited by the ant Pheidole Aurivillii v. kasaiensis. Lamborn 
reports that the same larva does not attack different Homoptera. But as he does not seem to have always 
bred the lepidoptera, it may be possible that there were among the larvae also some of the other closely allied 
species. 
angulosus. M. angulosus Griinb. is unknown to me, but it is evidently very closely allied to the preceding. The 
description says: ,,Allied with M. zymna Dbl. 6c Hew., somewhat larger, of different contours of the wings; 
A wings longer, narrower, elliptical, particularly the hindwings, which form a rounded angle at vein 5; margin 
of forewing distinctly feebly undulate; forewing of the $ broader, at the apex almost rectangularly angled, 
the margin more distinctly undulate; hindwing at vein 5 extended into a lobe, almost lancet-shaped, the anterior 
part of the margin at vein 6 flatly indented. Marking above as in zymna, the broad black apical spot of the 
forewing fills up the whole apical half and encloses the upper cell-angle. The black margin of the hindwing 
is in the A 2%, hi the $ up to 5 mm broad. Under surface very much like in zymna, the bands scarcely 
darker than the greyish-brown ground-colour, the white arcuate border-lines more or less distinct, the post- 
discal band in the area 5 rectangularly broken, the distal, white, boundary-bow in this area removed far distally. 
Expanse of wings: 38% to 43% mm.“ Spanish Guinea. 
simplex. M. simplex Rob. (= similis Ky.) (62 h) is perhaps a race of zymna and deviates only by the marks 
stated in the review. Cameroon to Uganda. 
metaleucus. M. metaleucus Karsch (65 f) is easily recognizable by the marking of the hindwings above and beneath. 
Ashanti to Cameroon. 
Second Group of Genera. 
This group likewise comprises but one genus having no allies, neither in Africa nor in other regions. 
2. Genus: Ijaclinociiema Trim. 
Small or medium-sized Lycaenids, the hindwings of which are rounded off without any angles or small 
tails. Forewing with a distinctly undulate, sometimes almost dentate margin. Antennae stout with short 
joints of the shaft and a gradually thickened circular club. Palpi moderately long, beneath roughly scaled. 
Eyes densely haired. Fore wing with 11, hind wing with 5 veins; vein 5 rises in both wings from the middle 
between 4 and 6; vein 6 and the footstalk of the veins 7 and 8 of the forewing from the same place, the apex 
of the cell; vein 9 of the forewing is absent, and veins 10 and 11 rise separately from the costal margin of the 
cell; veins 6 and 7 of the hindwing separated afar. The forelegs of the $ are, as in Arrugia, completely 
developed with jointed tarsi.
