The antennae are very long as in (i. grrmnn. The diflereme in length lietwoen the 

 right and left numdiMes is somewhat greater in (1. minor and in the next .spe<i«'.s than in 

 anv other. The mentum re.'*eml)les that of (i. gcnimri ; its scars are less deeply impre.s.sed 

 than in (i. tenimUrrnsis, hut more deo])ly inipre^.-^rd than in 0. carolinenaia. The lateral 

 area.>^ of the meta.sternum are sm«>oth and hairless. In other re.spects the present species

Numerou.s .specimens from Saparua Island, .several from ("eram (Kairatoe in the 

 Western and Roema.so.sal-Pa.sama in the rentral part of the island) and Huano. one from 

 Nuj'a-liaut. and one said to come from New (iuinea. Length 23-0-28-5 mm. 



6*. tuirirulntor can he distinguished from all other .species of the genus known to me 

 by the strongly and as a rule abruptly curved posterior nuirgin of the mentum, tln>ugh this 

 character is not always so clearly marked in .specimens from the mainland of Ceram as in 

 those from the • nig islands. The nntennal lamellae are comparatively short and 



stout as in d. '• •>, et«-. The nuintlihles resemble tho.se of (t. minor. The outer 



tubercles are soniewhat .slenderer than in G. gennari. which the present species resembles 

 in other respe<*t8.
