Head with round and sharply denned but not very large 

 punctures, nowhere confluent, but larger in middle of base of 

 clypeus than elsewhere; vertical front face of clypeus with 

 numerous setiferous punctures on sides, but confined to a 

 single row across middle. Antennae with fourth joint twice 

 the 5 length of third, and more than thrice the length of fifth, 

 sixth-eighth forming a club. Maxillary palpi with penulti- 

 mate joint much shorter than antepenultimate, and scarcely 

 more than half the length of apical, the latter rather long and 

 thin. Prothorax about thrice as wide as the median length, 

 front angles produced and acute, hind ones rounded off ; with 

 rather small and not very dense punctures. Eltyra slightly 

 dilated to about the middle; geminate-striae light but dis- 

 tinct, punctures much as on prothorax ; suture unarmed. 

 Pygidium strongly convex, and rather strongly asperate 

 about base, becoming smoother about tip. Basal joint of hind 

 tarsi distinctly longer than second. Length, 22 mm. 



Hah. — Western Australia: Cottlesloe, October, 1913 

 (No. 8194 of Western Australian Museum). Type, I. 7810. 



In Blackburn's table of Group 1, would be associated 

 with crinita, from which it differs in being larger and very 

 differently coloured, clothing in basal gutter of pronotum 

 much less dense. The dark prothorax and elytra (on close 

 examination these are seen in places to be obscurely diluted 

 with red) in striking contrast to the red head, is most unusual 

 in the subfamily. The rami of the club are quite as long as 

 the basal joint of antennae. The type appears to be a male. 



Group 2. 

 Haplonycha mixta, n. sp. 



Reddish-castaneous and slightly iridescent, elytra (except 

 narrowly along suture and margins) paler. Under-surface 

 and legs with dense golden pubescence; head with a few long 

 hairs near eyes, and on base of clypeus, lateral and basal 

 gutters and front margin of pronotum with long hairs, dense 

 at positions of hind angles ; membranous fringe of elytra very 

 short; pygidium with numerous rather short, stiff setae. 



Head with large crowded punctures about clypeal suture, 

 becoming smaller and sparser elsewhere; vertical front face 

 of clypeus unusually high, with rather dense setiferous punc- 

 tures on sides, but setae confined to a single row across 

 middle. Fourth joint of antennae very little longer than 

 third, sixth acute on one side, seventh-ninth forming a club. 

 Maxillarypalpi with penultimate joint much shorter than the 

 antepenultimate or apical ones, the apical densely punctured, 

 and with a conspicuous elongate depression or upper-surface.
