RAPHIPEZA; ARCHAEOPACHA. By Dr. C. Aurivillius. 
211 
On examining a typical specimen kindly having been lent me from Francfort, I found that the following species does 
not belong to the genus Lechriolepis, as I had presumed before, but that it is a Chrysopsyche. From this genus it only differs 
in the veins 4 and 5 of both wings being forked and vein 7 of the forewing rising on a short fork with vein 6; veins 9 
and 10 are very short and terminate into the costal margin, 9 almost into the apex. The differences from Lechriolepis 
are in fact exactly stated by Saalmuller. —• Subordinate genus: Trabaloides Kirby (= Protogenes Saalm.). 
Ch. stumpfi Saalm. (29 b). <j>. The figure makes an exact description superfluous. This species deviates stumpfi. 
from the of the species of Lechriolepis with respect to the marking of the fore wing by the dark basal area, 
the longitudinal streak in area 1 b between the transverse lines, as well as the broad submarginal band. The 
S is still unknown. Madagascar. 
4. Genus: ISaphipeza Bull. 
Eyes bare. Forewing: veins 4 and 5 shortly separated or from the same place, vein 6 from the apex 
of the discal cell or separated from it by a short upper discocellular vein, 7 and 8 forked from the apex of 
the cell, 9 and 10 much longer than their fork, 9 into the apex, 11 bent up towards vein 12. Palpi hardly 
projecting beyond the frons. Hind tibiae with terminal spurs. Tarsi above at the base scantily haired. 
Rh. turbata Butl. (= graphiptera Saalm.; $ = echinata Saalm.) (29a). <$. Median area of forewing turbata. 
between the costal margin and vein 2 filled up with a deep blackish-brown, with lighter veins. Ground-colour 
of both wings light grey and indistinctly strewn with light fawn-coloured nebulous spots. The transverse lines 
of the fore wing are whitish. — $. Median area of forewing much lighter with blackish veins and a large black 
discal spot; transverse lines also blackish. Expanse of wings: 29 {<$) to 44 ($) mm. Madagascar: Nossi-Be, 
Antananarivo. 
3. Subfamily: Archaeopachinae. 
This subfamily is allied to the preceding one by the veins 7 and 8 of the hindwing being quite separate 
and parallel, but it has, like the following subfamily, a long though less broad basal cell which is closed by 
a cross-vein between vein 8 and the anterior edge of the discal cell; this ,,cross-vein 1 ‘ makes entirely the impression 
of being the base of vein 8, in which case the very thick vein forming the anterior edge of the basal cell must 
be explained as a 9th vein or a combination of veins 9 to 12, touching vein 8 in one point. The neu- 
ration also differs besides from the typical neuration of the Lasiocampidae. Veins 4 and 5 are in both wings 
separated at their base; the veins 6 and 7 of the hindwing are forked; vein 6 of forewing is separated from 
vein 7 by the distinct upper discocellular vein; vein 7 as well as the fork of the veins 10 to 8 proceed from the 
apex of the discal cell. The discal cell is in both wings divided into two almost equally large parts by a 
revertive longitudinal vein, distally very much widened and closed by a long median cross-vein which is deeply 
angular towards the base. Palpi slantingly porrect, hardly projecting beyond the hairing of the frons. Eyes 
bare. <$ antenna as far as the apex with two rows of medium-long pectinations. Head and thorax hairy. 
Abdomen clad with large scales. Anterior tibiae unarmed; hind tibiae with four spurs; claws plain. Wings 
entirely margined, at the distal margin rounded off; anal margin of forewing in the centre bulged out; costal 
margin of hindwing moderately bent. 
1. Genus: ArcJiaeoftaclia Auriv. 
(Description of the subfamily.) 
A. obsoleta Auriv. The only specimen known of this species unfortunately is so badly preserved that obsolete/. 
the colouring and marking of the wings cannot be described. Thorax above covered with greyish-yellow hair. 
Abdomen whitish. Wings yellowish-grey (?), probably with a darker longitudinal stripe in 1 b and the discal 
cell. By the shape of the wings and the size it recalls Bombycomorpha and Chondrostega. Abdomen pro¬ 
jecting far beyond the hindwing. Expanse of wings: 26 mm. Central Africa: Rouchuru Plains. 
4. Subfamily: Gastropachinae. 
In this subfamily the veins 7 and 8 are likewise completely separated, the basal cell being closed 
by a cross-vein which unites vein 8 with the anterior edge of the discal cell. The basal cell is large or 
rather small, almost invariably shorter than the discal cell, and from its anterior edge it despatches towards 
the costal margin of the wing 5 or 6 very strong accessory veins which are entirely developed like usual 
veins. Vein 7 of the hindwing rises outside of the basal cell or from the same place near the apex of the 
discal cell, but always separated from vein 6. 
The genus Gastropacha (type: G. quereijolia L.) is unknown to me from the Ethiopian Region. Three 
other genera, however, occur there, one of which has its patria also in Southern Asia.
