 H. M. Giles): Fortescue River (W. D. Dodd); South Aus- 

 tralia: Peake (old collection). Type, I. 6661. 



With the head longitudinally concave as in caviceps, but 

 the elytra opaque, with much smaller punctures (they are so 

 small and asperate that the surface appears shagreened), the 

 costae feeble and traceable only about base, and the pale 

 markings (when present) bounded by costae ; the lateral vittae 

 of the prothorax are also' much less pronounced or absent. 

 There is usually a conspicuous infuscation between the eyes; 

 on the pronotum there is .a distinct but not very sharply- 

 defined median infuscate vitta, and the sides are lightly (if 

 at all) infuscated; the elytra are usually rather deeply 

 infuscated), with a conspicuously paler (but not sharply 

 denned) patch occupying a fairly wide sutural space, from 

 about the basal fourth to beyond the middle, thence becoming 

 narrowly sutural ; most of the abdomen is infuscated, the tips 

 of the mandibles are black. On one specimen the median 

 vitta of the pronotum is represented only by remnants at the 

 base and apex; on the Peake specimen the pale portion of 

 the elytra is more conspicuous than usual. Two specimens in 

 Mr. Carter's collection probably belong to this species, their 

 elytral markings to a certain extent are suggestive of those of 

 Copidita bipartita, but they differ from Champion's descrip- 

 tion in having the mandibles simple, elytra with the costae 

 not "rather sharp," and in some particulars of colour. 



OXACIS MAJORINA, n. Sp. 



9 . Of a pale and rather dingy flavous or stramineous, 

 elytra very vaguely infuscated towards the sides and pos- 

 teriorly; tips of mandibles black. Rather densely clothed 

 with short and somewhat golden, depressed pubescence. 



Head lightly convex about base, widely and rather 

 shallowly concave in front; with dense and sharply-defined 

 but small punctures, becoming rather sparse in front; 

 mandibles simple. Eyes large, lightly incurved in front. 

 Antennae long and thin. Prothorax scarcely longer than the 

 greatest width, sides gently dilated from near base to near 

 apex, base narrowly upturned, with three feeble discal 

 impressions ; with crowded and small but rather sharply- 

 defined punctures. Elytra considerably wider than base of 

 prothorax; with scarcely visible remnants of discal costae, 

 surface finely shagreened. Length, 11^-12^ mm.
