Neir Zealand Coleoptera. 97 



wing of the mesosternum does not quite meet the meta- 

 sternum. As the general structure of the under surface 

 is not very different from that of Tetrorea, it may be 

 placed next to that form. 



Mesolamia marmorata, n. s. 



Fuseo-rufa, pube flavescenti subtili dense vestita, ma- 

 culis fusco-rufis adspersa ; elytris parum inaequalibus, 

 singulo ad apicem rotundato. Long. 9 — 12 mm. 



The surface is apparently of a dark or obscure red 

 colour, closely covered with a fine, closely adpressed, 

 yellow pile, but in parts this pile is replaced by a pile of 

 a darker colour, thus giving rise to a maculated appear- 

 ance, most of the sj)ots being of small size and round in 

 shape. The antennae are rather stout, and are not 

 hispid ; each joint bears rather scanty pale pile on the 

 basal portion, and this therefore appears paler than the 

 apical part of each joint. The vertex is deeply chan- 

 nelled, and between the antennae there is a rather deep 

 depression, which is continued on the front of the head 

 as a fine channel. The thorax is narrower than the 

 elytra, and is not so long as broad ; on each side it is 

 much dilated to form a large angular prominence ; the 

 surface is not at all tuberculate, only a little uneven, 

 and bears numerous small spots of the kind already 

 described. The surface of each elytron is elevated near 

 the base on each side of the scutellum, and there is also 

 on the middle of each an obscure longitudinal folding or 

 elevation ; there is a large, irregular, curved, dark mark 

 on each, as well as numerous small spots. The rather 

 stout, short, legs are destitute of setae, but are clothed 

 with fine pile ; the femora are a little maculate, and 

 there is a dark mark on each tibia below the middle. 



The female has the apical ventral segment very largely 

 impressed, and at each side bears elongate pubescence, 

 which projects towards the middle, and so much conceals 

 the dej)ression. The male is unknown. 



Two specimens of this species were sent from Dunedin 

 by Prof. Button in 1877.
