102. Mr. Malcolm Burr’s Preliminary Revision of the 
Opisthocosmia in which the pronotum is more or less square 
and not distinctly narrower than the head; the antennz 
are the same as in true Opisthocosmia, but perhaps a little 
less slender, and the segments proportionately shorter ; 
the forceps are simpler than in true Opisthocosmia and the 
feet are somewhat less slender and shorter. 
The type of the genus.—Opisthocosmia hwmeralis, Kirby, 
Journ. Linn. Soc., vol. xxiii, p. 528, 2. (1891.) (Ceylon).

Genus 4.—SARCINATRIX, Rehn.

ventrali) ¢ angulis postico-exterioribus in processus tuberculiformes 
productis. 
Sarcinatrix sub-genus, Rehn, Proc. Ac. Nat. Phil, p. 308. 
(1903.) 
Rehn suggested this name for a sub-genus which he 
characterised by the processes of the subgenital lamina of 
the male, which is produced into a “recurved spiniform 
process, which flank the lateral base of the forceps 7 = Aten 
the typical species described by him, the forceps of the 
male are parallel throughout their entire length; but this 
is not a generic character, for in my collection I have a 
second species in which the forceps are distinctly bowed.
