216 NEW SPECIES OF AUSTRALIAN COLEOPTERA, VIII., 



surface of abdomen impunctate, except at the apex of the 

 segments. Length 3 J, to apex of elytra 1^- mm. 



Hab. — Swan River, W.A. (two specimens taken from a nest of 

 Coptotermes Raffrayi). 



In some respects it appears to agree with the description of 

 D. myrmecophila, but the sides of prothorax not provided with 

 " seven or eight erect setae," having in fact only two (one at base 

 and one at apex). 



Dabra convexicollis, n.sp. 



Moderately broad and somewhat shining, the abdomen highly 

 polished. Brownish-testaceous, basal and apical joints of antennae 

 and the legs paler. Densely clothed with short golden-grey 

 pubescence, except on upper surface of abdomen, which is almost 

 glabrous; each side of prothorax with four long brownish hairs, 

 of the elytra with three, each abdominal segment with from one 

 to three hairs at the sides, and a fringe of setigerous punctures at 

 the apex, the apical segment, however, densely pubescent. 



Head densely punctate. Antennae stout, terminal joint com- 

 pressed and as long as the three preceding combined. Prothorax 

 strongly transverse, convex throughout, sides strongly rounded 

 and nowhere flattened, base bisinuate, the posterior angles 

 produced and acute; densely and regularly punctate. Elytra 

 slightly narrower and scarcely longer than prothorax (at its 

 longest), each feebly separately rounded at apex, but the posterior 

 angles acute and produced; punctures as on prothorax. Abdomen 

 regularly diminishing in width from base to apex, upper surface 

 (except at apex of each segment) impunctate, lower densely and 

 finely punctate. Length 2J, to apex of elytra 1^ mm. 



Hab. — Forest Reefs, N.S. W. (two specimens taken from the 

 nest of a " green " stinging ant under a stone). 



Differs from the preceding and from the two previously 

 described species by the prothorax being regularly convex 

 throughout. 



The genus Dabra will probably be found to be numerous in 

 species when the nests of ants and termites have been more 

 systematically examined than they have been up to the present.
