The following characters, which are found in this species, 
seem to fix its position in the genus, according to the system 
adopted by Chaudoir in his Monograph of the genus Chlaenius 
(1876), near Ch. Semperi Chaud. (1) Abdomen hardly, or but little 
punctate near sides; (2) elytra with interstitial punctures not 
ocellate; (3) met-episterna not sulcate near outer side; (4) elytra 
with marginal channel not angulate at shoulders. It evidently 
differs decidedly from Ch. Semperi by the shape of the prothorax. 
No species at all nearly related to Ch. occultus has been reported 
from New Guinea, or Australia. 
Tribe Harpalini. 
Gnathaphanus laeviceps Macleay. 
Gazelle specimens (3) 11.5—13.5 mm in length. 
Note: I have also seen it from Astrolabe Bay. The speci- 
mens from New Guinea and New Britain seem smaller (but not 
otherwise different) than the species as found on the mainland.

Victoria, VIII, 1868, p. 185. 
Gazelle Peninsula. (3 specimens d a. 2; length 10 —11.5 mm, 
breadth 3.8—4.25 mm.) 
Note: I consider this species to be the same as the New 
Caledonian Amblygnathus impressus Montız.; it is also conspecific 
with Harpalus alternans Cast., from Queensland. I suspect the 
identity of Gn. impressus with Gn. lieinoides Hope (1842), but 
Hope’s description is too vague for a definite opinion to be 
formed on this point without inspection of his type, or the dis- 
covery that the range of Gn. impressus extends to Port Essington. 
Hope gives the measurements as 5°/, X 1°/, lines; a specimen 
from Townsville, Queensland in my collection measures 12.5 X 
4.5 mm. 
Gnathaphanus impressipennis Castelnau. 
Gazelle Peninsula. (Several specimens.) Also found in 
Australia and New Caledonia. 
The three Papuan species of Gnathaphanus may be tabulated 
as under: 
Elytra very strongly sinuate at apex; head large; colour 
black (including legs). 5 
Elytra not mucronate at apex, 3" interstice only 
seriate-punctate. laeviceps Macleay.
