h. Subgroup of Chelifer subkobustus Balz. 



Flagellum consists of three hairs. Cephalothorax generally with some ocular spots and 



without transverse grooves or ivith a median one. The proximal joints of palps 



short and clumsy in contradistinction to long and slender chela, which has hand 



much longer than tibia. Tarsal tactile hair at least a half removed from the base. 



With the very scanty material at my disposal it is very difficult to mark this group 



sharply off from the following, but I am, nevertheless, practically convinced that it is 



quite a natural one. The shape of the cephalothorax, generally without transverse 



grooves, the contrast between the slender chela, with hand which is distinctly larger 



than the finger and much longer than the tibia, and the clumsy femur, together with 



the elongated coxae, give these species a peculiar appearance, somewhat similar to that 



of Chelifer rudis Balz.* The three previously known species referred to this group 



were originally described as belonging to Atemnus Can., but I think that the presence 



of accessory teeth on fingers of palps and the position of the tarsal " tactile '' hair, well 



removed from base, make it necessary to place these species apart from Ch. nidificator 



Balz. &c. 



14. Chelifer subgkacilis, sp. n. (Plate XXX. figs. 11 a-b.) 



Female. 



Cephalothorax. — Two fairly distinct ocular spots. The cephalothorax, which is 

 somewhat longer than wide, has the membranous cucullus which covers the base 

 of the antennai very well developed; only the anterior transverse groove, which is 

 slightly curved backwards in the middle and fairly prominent, is found. The integu- 

 ment is minutely, but distinctly granular, except in the hindmost part of the second 

 tergite ; the hairs are short and slightly clavate. 



Abdomen. — The abdomen, which is not very slender and somewhat depressed, has all 

 the tergites except the hindmost part of the eleventh divided by a wide longitudinal band. 

 The sclerites are indistinctly granular with scale-shaped granules; and the tergites 

 bear from 12-16 generally rather short and slightly clavate hairs along the hindmost 

 margin, in addition to two lateral ones distinctly, and two median ones, very indistinctly, 

 in front of the row. A moderately big round spot, covered with numerous short 

 hairs, is observed in front of the vulva. The dorso-ventral integument is beset with 

 densely placed, parallel, undulated, longitudinal ridges. 



Antennce. — The rather slender galea, which possesses six short terminal branches, 

 scarcely extends beyond the terminal hair. 



Palps (PI. XXX. figs. 11 a-b). — The maxillce are almost smooth in the middle, but 

 granular laterally ; the trochanter, femur, and in a less degree the tibia, are distinctly 



* Marked diiferences from this species are, however, found in number of tergal hairs, &e.
