6 Records of the Indian Museum. [Voiv. X, 



Ch. australiensis). Tibia a little shorter and somewhat broader 

 than femur, with very strong stalk, on the posterior side mode- 

 rately and regularly convex, in front somewhat more convex, 

 or rather somewhat swollen. Hand with a distinct stalk, and 

 the base somewhat obliquely truncate with the inner corner 

 broader and more rounded than the exterior one; the hand is 

 about as long as, but considerably (i-J times) wider than tibia, 

 and about as high as broad, the inner side strongly convex 

 (nearly semicircular), the outer side much less so, on both sides 

 passing gradually into the fingers. Fingers robust, strongly curved 

 and a little longer than the hand ; the jSxed finger exteriorly with 

 9-10 small accessory teeth in the distal half ; on the inner side 

 both fingers have 2 to 3 small accessory teeth near the tip ; the 

 fingers do not gape at all. 



Mandibles: Galea with robust trunk and deeply tripartite 

 tip, and along one side of the trunk provided with 7 long filiform 

 teeth, increasing in length towards the base. 



Legs minutely granulate with slightly clavate and dentate 

 hairs. The trochantin of the two posterior pairs of legs perpen- 

 dicularly articulated. Coxa IV very robust, much broader than 

 trochanter, along the posterior margin provided with dense rows 

 of long hairs. The tibia of all legs considerably longer than the 

 tarsus. Claws simple. 



The species belongs certainly to the cimicoides-groM^ , as the 

 sexual area as well as the whole appearance seems to indicate ; 

 the animal reminds one ver^' much of a large Chelifer cimicoides.

The only species among the Asiatic-Australian forms, with 

 which the new species has a nearer relation, is Chelifer australiensis , 

 With ; yet there are some essential characters in which the two 

 species differ from each other, so they certainly cannot be united. 

 Contrary to the characters mentioned above in the description 

 of the new species, With's species (from Queensland) is distin- 

 guished as follows; "Two rather distinct grooves" on cephalo- 

 thorax ; "traces of lateral projections or keels on the tergites " ; 

 galea has only some shorter teeth at the tip ; " the palps are 

 indistinctly granular" ; the protuberances of the trochanter have 

 another shape; the hand "higher than broad"; the fingers also 

 interiorly with "accessory teeth" near the middle. The differ- 

 ential characters are not great, but taken together they are 

 certainly sufficient to distinguish the two species.
