Regarding it as such it would be associated with sloanei, to 

 which it certainly looks very close, but it differs in being 

 larger, punctures on head much smaller and less rugose, and 

 by its pygidium ; on the present species that portion is 

 entirely glabrous, and its upper surface has rather small but 

 sharply defined transverse punctures, becoming much smaller 

 and very sparse towards the tip, where also the derm is 

 shining; on a co-type of sloanei the surface is slightly shining 

 throughout, somewhat shagreened, and with numerous short 

 stiff setae on the basal half. In general appearance it is rather 

 close to firma, but that species has the upper-surface of the 

 head and the pygidium clothed. The two specimens in the 

 Museum are probably females, their elytra are slightly paler 

 than the other parts of the upper-surface, but not conspicu- 

 ously so. 



Haplonycha bimuchonata, n. sp. 



Dark piceous-brown and iridescent; some parts almost or 

 quite black, antennae reddish, club paler. Sterna and legs 

 with dense golden-brown hairs, a few similar hairs forming 

 a fringe in each lateral gutter of pronotum ; membranous 

 fringe of elytra long, not much shorter than fourth joint of 

 hind tarsi ; pygidium glabrous. 



Head with crowded and moderately large punctures, 

 more crowded about clypeal suture than elsewhere ; clypeus, 

 in addition, with numerous small punctures amongst the 

 larger ones; front face of clypeus with numerous punctures, 

 but in middle the setiferous ones confined to a single row. 

 Antennae with fourth joint slightly longer than third, the 

 two combined scarcely longer than second, seventh-ninth 

 forming a rather small club. Maxillary palpi with penultimate 

 joint slightly longer than antepenultimate, and slightly 

 shorter than apical. Froth orax about thrice as wide as long, 

 sides strongly and evenly rounded, front angles acute and 

 produced, hind ones obtuse but not completely rounded off; 

 punctures rather denser and larger than usual. Elytra 

 slightly dilated posteriorly ; geminate-striae moderately dis- 

 tinct, punctures fairly numerous but (except in the striae) 

 usually smaller than on prothorax ; suture strongly bimu- 

 cronate. Pygidium with numerous small punctures and a 

 conspicuous median carina, the propygidium close to its 

 suture with a conspicuous, bisinuate, briefly setose ridge. 

 Basal joint of hind tarsi distinctly longer than second. 

 Length, 14 mm.

In general appearance somewhat like firma or a small 

 solida, but palpi, suture, and pygidium all very different. In
