" Vulva ex area sat ])arva subpentagona, nitida, pallide 

 fusca, ad utrinque anguluin lateralem macula nigra notata 

 constat, qure posticc truncata est, lateribus rectis sensim 

 angustato-acuminala : lirec area excavata est et septa cruci- 

 formi munita, cujus ramus posterior, reliquis longior, foveas 

 duas oblongas separat. Pone lianc aream callum fortem 

 triuisvcrsum convcxum nitidum jiallide fiiscum video." 



Thorell says of this species, the form of whose vulva is 

 sufficiently difficult to grasp from the description, " pedibus 

 longis et forma vulvaj notabili satis distincta est."

" Vulva figura:^ i'ungi (Agarici) humilis sat similis est: ex 

 callo maximo, alto, deplanato, transverso et triplo-quadruplo 

 latiore quam longiore constat, qui postice ample rotundatusest, 

 antice in medio quasi in ])ctiolum basi angustum^ tum dila- 

 tatum ])roductus et utiinque, apud eum, pauUo eniarginatiis : 

 apices rotundati hujus calli (pallide fusci) nigri sunt." 



The general form of the vulva is clear from the description, 

 and ]uoves the species to be quite distinct from the females 

 taken in Pinang by Mr. Flower, described below, though it 

 must be closely allied to another form before me from Java, 

 as well as to valvularis.
