On some Asiatic species of Rhogadinae ete. 9 
fuscous, the 24 a little longer than wide, the 3” square, the others 
wider than long and covered with a pale pile. Face and metathorax 
covered with long white hair. Spurs minute. Claws narrow, curved, 
simple. Pleural furrow wide, smooth. 3'4 antennal joint shorter 
than the 4%, 
This species agrees fairly well with the description of Penta- 
pleura. Foer., except that the metanotum in that genus has no keel, 
while the present species has on it a transverse and loneitudinal 
one. Having in my collection very few types of the Alysüdae and 
the Genera being founded on minute structural characters I do not 
care, at present, to found a new genus for the reception of flavipes. 
Rhacalysia gen. nov. 
Recurrent nervure interstitial; 2"4 discoidal cellule open below. 
Radius issuing from near the base of the apical third of the stigma. 
Transverse median nervure received beyond the transverse basal. 
Pleural furrow wide, erenulated. Metanotum areolated. 3" antennal 
joint shorter than the 4". Mandibles tridentate. First abdominal 
segment longish, narrower than the 2”4, stoutly longitudinally striated ; 
the others are smooth. 2” cubital cellule 4-angled; the 2”d abseissa 
of radius longer than the 1° transverse cubital nervure. Stigma 
linear. Anal nervure issuing from near the bottom of the trans- 
verse median. 
The parapsidal furrows distinet, the middle lobe of mesonotum 
triangular, clearly separated. There are 2 large transverse areae on 
the base of the metanotum, bordered by a keel behind; there are 
3 apical areae, the central smaller than the others and narrowed 
towards. The outer mandibular teeth are triangular, of almost 
equal size and separated by a triangular incision, the inner tooth is 
wider, blunter and less clearly separated. In the hind wings the 
postbrachial and the praebrachial nervures are interstitial; the latter 
is received shortly before the radius; the anal cellule is divided 
shortly beyond the middle by a distinet transverse nervure. Clypeus 
clearly separated. Legs longish, slender ; the spurs minute, slender ; 
the claws slender, longish, curved. 
In the Arrangement of Szepligeti (Gen. Ins., Brac., 200) 
this genus would come in near Pentapleura. From the species I 
have, in this paper, doubtfully deseribed as a Pentapleura, it should 
readily be known by the areolated metanotum, striated basal ab- 
dominal segment, by the recurrent nervure being received in the 1* 
Wiener Entomologische Zeitung, XXIX. Jahrg., Heft I (15. Jänner 1910).
