jEthina tumida. 



Nigra, subrotundata, punctatissima, subnitida, 

 lateribus ciliatis, supra baud pubescens, infra 

 velutino pubescens. 



Long. 3^ lin., lat. 2 lin. 



Black, very convex, broad oval or roundish, 

 very closely punctate, so as to give a little dull- 

 ness to the surface, still somewhat shining ; the 

 punctuation on the elytra so close as to seem irre- 

 gular ; but on closer examination it is seen to be arranged longi- 

 tudinally, and, in certain lights, streaks, as of striae, are visible. 

 The lateral margins of tborax, elytra, and pygidium are ciliated 

 with a fringe of close, short, bright tawny-coloured hairs ; the 

 disk of the thorax convex, and the convexity prolonged back- 

 wards, something like a raised lobe, to the middle of the base, 

 descending rapidly so as to make a hollow on each side ; the 

 base deeply bisinuate, the posterior angles prolonged backward, 

 overlapping the elytra, and acute, but with the points rounded ; 

 the apices of the elytra broadly truncate and rounded both at the 

 sutural and external angles. The pygidium large and broad, 

 punctate. The underside very faintly punctate, clothed with a 

 thick coating of velvety pubescence of a tawny colour, longest 

 along the margins of the segments of the abdomen. The legs 

 are broad and flat, the tibise folding within the femora, as in the 

 Strongylini, and the tarsi short, dilated, and villose. 



It may be that the absence of pubescence above in my species 

 is due to its having been rubbed off; but I think not. If it 

 had been so, some traces would have been left of it, while none 

 exist, except below, where it is sufficiently abundant. 



I have only received two specimens, both from the Rev. W. 

 C. Thomson. 



- Amphicrossus, Er. 



1. Amphicrossus concolor. 



Late ovatus, convexus, subnitidus, pubescens, Isevissime punc- 



tatus, castaneus, lateribus parum rufo ciliatis. 

 Long. 3 lin., lat. 2;^ hn. 



Broadish oval, convex, very finely and irregularly punctate, 

 finely pubescent, the sides ciliated, with a very narrow fringe. 

 Head with scarcely any impressions. Prothorax emarginate in 

 front; anterior angles broadly projecting; posterior angles 

 rounded ; base bisinuate ; sides slightly explanate, the depressed 

 portion narrowest in front. Scutellum triangular. Elytra with 

 the sides explanate and the margin reflexed and broadly inflexed 

 on the underside ; shoulders large, elongate, roundish, and promi-
