Head with moderately large crowded punctures; front 

 face of clypeus with numerous setiferous punctures on sides, 

 but the setae almost confined to a single row across middle. 

 Fourth joint of antennae much longer than third, and more 

 than twice the length of fifth, sixth-eighth forming a club. 

 Prothorax fully thrice as wide as the median length, mar- 

 ginal gutters dilated to apex, with the front angles produced 

 and acute, sides oblique from apex to beyond the middle, 

 and then arcuate to base, where each angle is almost rect- 

 angular : with rather small scattered punctures. Elytra 

 feebly dilated posteriorly ; with fairly numerous and almost 

 evenly distributed punctures of moderate size, striation lightly 

 denned ; apical mucros sharp, and slightly longer than mem- 

 branous fringe. Pygidium asperate but becoming polished 

 at tip. Basal joint of hind tarsi just perceptibly longer than 

 second. Length, 15 mm. 



Hah. — South Australia: Crecy. Type (unique), I. 4603. 



I have closely examined the fourth joint of the antennae : 

 from some directions a notch on one side of it causes the 

 antennae to appear to be nine-jointed, but from other direc- 

 tions the continuity of the fourth is quite distinct ; both 

 antennae are alike, although I broke off onq to examine it 

 more closely. Its antennae being eight-jointed, this species 

 could only be referred to Blackburn's Group 1, but it cer- 

 tainly looks out of place there, and more like some members 

 of Group 4. In the table of the group, whilst belonging to 

 A, it could hardly be referred to B, as the sides of the pro- 

 thorax are sinuate near the base, and it could not be referred 

 to BB, <n ) as the head is densely and in places confluently 

 punctured. I have not dissected out the maxillary palpi, 

 but the penultimate joint appears to be subequal to the ante- 

 penultimate, and is distinctly shorter than the apical. The 

 geminate striae of the elytra are less close together than 

 usual, and the punctures between them are quite as close 

 together as those between the other striae. 



Haplonycha erythrocephala, n. sp. 



Blackish, and somewhat iridescent; head, sterna, and legs 

 reddish. Under-surface with dense, long, almost white hairs, 

 becoming darker on legs, all gutters of pronotum with long 

 erect hairs, more numerous in middle of apex than elsewhere, 

 disc with a few scattered ones, elytra with a few long hairs 

 on suture and on apical slope, and with numerous minute 

 depressed setae ; membranous fringe very short ; pygidium 

 with numerous long hairs, and a few short setae.
