MR. H. R. HOGG ON SOME 



the males have the long mandibles and the females the short, 

 but discrepancies have to be cleared up before this can be 

 accepted for a certainty. It may be regarded as quite certain 

 that the difference is not specific, both forms being found in 

 members of the same species. 



White's short description* of the type species P. listeri, and 

 Simon's note on the original types in the Paris Museum t, show 

 that the specimens originally described had the long mandibles, 

 but the sex was not determined. Mr. Pocock, judging from 

 specimens, said to be females, in the British Museum, records 

 -P. listeri among those species with the shorter mandibles, 

 thereby distinguishing it from his P. albipalpis, which had them 

 long. Therefore, if his determination is correct, there are both 

 long and short mandibles in that species. 



P. trippi Poc. with long mandibles, is a male. 



P. ^asmawim Hogg „ a dried specimen, sex undeterminable. 



P. nigripalpis Poc. „ „ is a male. 



P. tvatjtsi, sp. n. ( from the shape of the genital oper- 



F. pococTci, s^.n. " " " X cula I take to be males. 



P. coronata Poc. with short mandibles, sex not recorded. 



P. halli, sp. n. „ „ „ operculum broader and straighter in 



specimens with short mandibles. 



Mandibles long in specimens cer- 



tainl}' males. 



F. groiji, s^. w. „ „ „ operculum broader, female. 



On the other hand, Mr. Pocock first described his P. jenningsi 

 as having short mandibles and as a female, but later found it to 

 be a male. Here, however, the basal segment of the mandible is 

 twice as long as the palp, and the second segment six times as 

 long as wide, which is hardly a short mandible when compared 

 with that of the females recorded above. 



Mr. Pocock gives a synopsis of the species described (Ann. & 

 Mag. Nat. Hist. May 1903, p. 438), and this I supplement
