OECETICUS; CLANIA. By M. Gaede.

was said in general that the female pupa did not turn round at all for the pupation. This, however, has been 
ascertained to be wrong for many species, and C. Bebg even succeeded in fixing such a copulation by swiftly 
killing the couple in situ (the South Amerian Oiketicus platensis), so that the mode of pairing could be made 
clear. The $ clings to the lower end of the sac, frequently using the supporting piece of wood provided by the 
female larva ( Clania moddermanni, ignobilis ) and shoves the abdomen being extended like an accordion onward 
through the whole length of the sac (according to von Linstow between the often only burst but not stripped 
pupal shell and the female body) as far as the sexual opening near the anterior end of the sac, where the im¬ 
pregnation takes place. 
It has not yet been ascertained whether this impregnation is necessary in very many species, and of 
which species the 9 is able to produce a breed also parthenogenetically. In Apterona the virgin generation has 
been ascertained; of Oiketicus platensis (vid. Vol. II) I could not obtain any larva from many thousands of 
non-fecundated eggs. 
Considering the great difference of the sacs, which, as we mentioned above, is often caused by the 
building material and by no means signifies a difference of species, we are glad to find that but few of the 
numerous forms of sacs contained in museums have led to denominations. Before the imago has been discovered, 
such denominations are of little use. 
1. Subfamily: Oeceticinae. 
In the fore wing vein lb anastomoses with 1 c and despatchesseveral 
branches to the inner margin. Basal ray in both the cells forked. 
1. Genus: OeceticilS Landss. Guild (Oiketicus.) 
Antennae pectinate to % of their length. Wings narrow. Abdomen long. Anterior tibiae with a long 
spine. Type: kirbyi L. G. from Central America. 
Oe. sacalavus Mab. Eorewing lancet-shaped, deep black. Hindwing large, triangular, with a large bow sacalavus. 
from the apex to the anal angle inward, strongly reducing the surface. Colour also black. 22 mm. Madagascar. 
Oe. angulatus sp. n. (72 h). Body and wings blackish brown. Forewing in the exterior half of the angulatus. 
cell and behind it almost black. Around the cross-vein an almost square hyaline spot. Hindwing from the inner 
margin to the cell light diaphanous. The distal margin is only slightly concave. 30 mm. Gabun. Type in the 
Berlin Museum. 
2. Genus: Clania Wkr. 
Antennae of $ bipectinate to the tips. Anterior tibiae with a long tibial plate. In the fore wing veins 
4 -(- 5 on a short stalk, 8 + 9 on a longer one. In the hindwing from vein 8 several spurs to the costal margin. 
Type: lewini Ww. from Australia. 
Cl. cervina Drc. Forewing brownish-red, the veins black, the spaces between them with pale streaks, cervinu. 
At the end of the cell a long brown spot and at the apex 3 white spots. Hindwing smoky brown with 3 white 
sjjots at the apex. 42 mm. Gambia, Delagoa Bay, East Africa. 
Cl. moddermanni Heyl. (72 h). According to the author and to Prof. Janse it is different from cervina, moddcr- 
but this difference is probably only due to the incorrect description. If we place instead of “at the cell-end” mama 
behind the cell brown, and instead of “at the apex” at the distal margin below the apex white marginal spots 
of a very variable distinctness (on the hindwing they are almost invariably absent), we have the description 
of moddermanni. <$ 32- 38 mm. 9 yellowish-brown, on the head and the 3 first segments glossy. The larval 
casing is 50 to 80 mm long, spun with branchlets of 2 or 3 mm thickness, of 15 to 25 mm diameter. pictipennis pidipennis 
Strd. (72 h) is larger and more contrastingly marked, particularly the white marginal spots mentioned in cervina 
are mostly very distinct. 40 46 mm. Liberia to Spanish Guinea, Delagoa Bay, Urundi. 
Cl. zelleri Heyl. This species and the two following ones have been described only according to the seller i. 
larval sacs. The imagines belonging to them are unknown, so that the descriptions are of but little value. 
Length 35 mm, diameter 7% mm. A very remarkable fact is that the anterior soft portion is vertically set with 
short pieces of grass, the rest with oblique grass-blacles of 15 25 mm length. - Probably no species of 
Clania at all. 
Cl. ngarukensis Strd. The sac is about 45 mm long, set with grey thorn-needles of about 40 mm length ngaruken- 
and 1 mm thick, of about 12 mm diam. In front the light reddish-brown cocoon looks out. East Africa.
