Head roughly punctate, with a number of short, costifonn, 

 irregularly placed elevations, of which the longest is on each 

 si'de, above the eye. Antennae short, first joint as long as 

 second-third combined, but partially concealed from above ; 

 second-seventh of equal size and strongly transverse ; eighth as 

 long as sixth-seventh combined, a.nd increasing in width to 

 apex, which is truncate. Prothorax subquadrate, apex feebly 

 emarginate, base rounded ; with four longitudinal costae all 

 united at the base and apex, the outer ones with rounded 

 corners ; surface roughly punctate. Elytra each with five costae, 

 the first short and subsutural, the fourth united with third 

 at about one-third from apex, then united with second at one- 

 foiu-th from apex, then ol^lique almost to inner apex ; surface 

 roughly punctate, tlie punctures in two more or less regular 

 rows. Under surface and legs densely punctate, the punctures 

 with a granulated appearance. Length, '^--1^4 www. 



Hab. — Birchip.' In nests of Iridomyrmex nitidus. 



The head in front is truncate, then rounded and diminishing 

 to about the middle (where the eyes are situated), then dilated 

 and again diminishing to base. The pi"otlioracic costae divide 

 the prothorax into five almost equal longitudinal spaces. On 

 each side of the prosternum there is an oblique ridge, evidently 

 for the protection of the front legs ; the middle legs are pro- 

 tected by a ridge on each side of the intercoxal process of 

 mesosternum ; whilst the hind legs are protected by a ridge on 

 each side of the middle of the basal segment of abdomen. The 

 antennae (which reach back to just beyond the apex of pro- 

 thorax") are evidently protected by being laid back below the 

 latei'al cephalic costae, with the terminal joint of each resting 

 between the outer costa of the prothorax and its margin. 



In two of the specimens before me the sheath of the penis is 

 exposed, but I can detect no external feature characteristic of 

 sex. The under surface appears to be covered with indistinct 

 scales, but these, even under a fairly high cnmpound power, 

 are never clearly delined, and, in fact, what appear to me to be 

 scales may reall}'' be mud. 



1 This species was known to the late Rev. R. L. King, althouf;h he did not describe It. 

 I have a specimen from his collection (now in the AustraHaii .Mu>iennO that was apparently 

 taken at Kma George's Sound, by Mr. George Masters
