MR. R. I. POCOCK ON SOME 



[Dec. 2, 



24 mm., whereas a female of P. leppancn measuving 9 mm. has a 

 second leg of 33 mm. in length. 



The female of this new species is a genuine Phcdangmm, whereas 

 the male approaches Rhampsinitus. 



The genus Rhamj^sinitus Simon (CR. Soc. Ent. Belg. 1879, 

 p. Ixxii) appears to me to rest upon an insecure foundation. 

 The species I have described below as Phalang'm'm {Rhavipsinitits) 

 teMfrons and spenceri difier fi'om P. lepjmnoi only in the greater 

 length of the mandibles and the greater size of the inferior spines 

 of their basal segment in the male. It is permitted to doubt 

 whether such a chai-acter should be granted generic rank. 



Phalangium (Rhampsinitus) spenceri, sp. n. (Text-fig. 79, A.) 



Colour of trunk light olive-grey above, with a paler yellowish 

 m.edian longitudinal line, 1 mm. wide, extending from the ocular 

 tubercle with a sinuous darker line external to it ; chelicei'se 

 yellowish brown, indistinctly banded longitudinally, the spines on 

 the basal segment black-tipped above, second segment mottled 

 with darker spots without and within ; legs yellowish red, darker 

 apically ; coxte clouded with chalky white ; abdominal sterna 

 whitish,

Flialangium {Wiampsinitus) spenceri, $ , and P. {Rh.) telifrons. 



A. Carapace and mandible of male P. (P/i.) spenceri, and 

 B. Carapace of P. (PA.) telifrons. 



Upperside of body finely and closely granular ; carapace (text- 

 fig. 79, A) with two pairs of spiniform teeth on each side of the 

 tubercle, a few marginal by Krohn's stigmata, and many on the 

 ante-ocular portion, that on the middle of the front border being 

 conspicuous ; the tubercle with foitr paii's of sharp spiniform 

 teeth ; a deepish transverse groove, followed by a row of spicules, 

 running to the base of the 3rd leg behind the ocular tubercle ; 

 this is followed by six transverse segmental rows of sharp spicules,
