MALCOLM BURR, NEW GUINEA DERMAPTERA. 313 
Family LABIDURIDAE. 
Subfamily Labidurinae. 
Genus Labidurodes, Dubrony. 
I. robustus, Dubrony. 
Upper Sermowai River, ca. 400 M., in scrub, 8. IV. 11, 
igen 2 ver larva. 
The genus Zabidurodes was erected by Dubrony in the 
man. Mus. Civ. Genova, vol. XIV,- p. 355, 1870, for the 
single species, L. robustus, from Fly River, New Guinea. 
No other species has since been discovered, for the various 
so-called Zabdzdurodes described by myself and by Shiraki 
are certainly not referable here; nor has Z. robustus been 
recorded since. 
Dubrony discriminates it from Psalzs by the presence of 
the pliciform tubercles on the second and third abdominal 
segments, but it is now admitted that this is not a generic 
character. 
The existence of a male and two females in this collection 
enables me to establish its true position. 
It is an undoubted Psalzd and from the original descrip- 
tion is perfectly recognisable: but the meso- and metasterna 
are produced into rounded lobes as in Momoeolabis and 
Titanolabis, to which it is undoubtedly allied. The perfectly 
developed organs of flight distinguish it from both; the penis 
resembles that of Ax?solabis in the long, narrow, apically 
rounded parameres. 
The female closely resembles the male, and the forceps 
are slightly straighter. 
Subfamily Brachylabinae. 
Genus Leptisolabis, Verhoeff. 
I. ? punctata, Dubrony. 
Zoutbron, VI—VII. ro, one larva.
