FORFICÜLARIA OF THE HUNGARIAN NATIONAI, AIUSEUM. ^ 485 



Java (Xantus) ; var. with forceps stouter, more strongly toothed. — 

 Singapore, 1895, 1 cf (Biro). 



56. 67i. elegáns Borm. var. — Java (Fruhstorfer) c?. 



I refer this specimen to Cli. elegáns, with some hesitation ; in gene- 

 ral appearance & colour it agrees, but in certain minor details, is dif- 

 ferent, for example, the head is uniform very dark red, with no black 

 (variable character) & the forceps have no strong double tooth near the 

 l)ase ; otherwise it agrees with de Bormans description, and a drawing of 

 the type. De Bormans specimen, described in 1900, was from Sumatra. 



Genus XVII. OPISTHOCOSMIA Dohrn. 



57. O. centurio Dohrn. — Borneo (Xantus).

 Sattelberg (Bíró). 



60. 0. mimiscula Dohrn. — Singapore (Xantus). 



61. 9 0. dux BoRM. — New Guinea: Sattelberg, 1 ç (Bíró). I am 

 unfamiliar with this species, and with some doubt refer this solitary 

 female to it.
