FORFICULAK

IA OF THE HUNGARIAN NATIONAL MUSEUM. 485 Java (

XÁNTUS); var. with forceps stouter, more strongly toothed. — Singapore, 1895, 1 d (BIRO). 56. Ch. elegáns BORM. var. — Java (FRUHSTORFER) d

. I refer this specimen to Ch. elegáns, with some hesitation

; in general appearance & colour it agrees, but in certain minor details, is different, for example, the head is uniform very dark red, with no black (variable character) & the forceps have no strong double tooth near the base

; 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. 0. centurio DOHRN. — Borneo (
