108 Mr. O. E. Janson's Notices of 



Maci'onota alveata, n. sp. 



Head bronze-green, the sides at the base golden-yellow and 

 pubescent; coarsely punctured, the centre longitudinally elevated 

 and smooth; clypeua widened and rounded in front, with the 

 a[)ical margin shallowly emarginate; antenna? and palpi red- 

 brown. Thorax bronze-green, the disc coppery ; rounded at 

 the sides, with the posterior angles produced and obtuse, the 

 basal lobe, strongly produced over the scutellum, lateral depres- 

 sions golden-yellow, pubescent and punctured, central depression 

 punctured and slightly pubescent in front. Scutellum nearly 

 concealed, punctured, with the sides narrowly margined with 

 yellow. Elytra red-brown, shining, with five silvery-white spots 

 on each, two of them subquadrate and situate close to the 

 suture, two transverse and lateral, and one, also transverse, just 

 before the apex; sides and apex very coarsely strigose and 

 sparsely pubescent, depressed, and with four interrupted stria? 

 next the suture behind the middle, apical margin rounded and 

 deeply serrate, the sutural spines short. Pygidium black, finely 

 strigose, with dense long golden pubesence and a large transverse 

 oval silvery-white central spot. Underside shining bronzy-black 

 tinged with coppery, sparsely punctured, and with large trans- 

 verse silvery-white pubescent spots at the sides ; mesosternal 

 process large and swollen, with an acute reflexed point at its 

 apex; legs bronzy-green, tarsi red-brown, anterior tibia? narrow, 

 the apical and two lateral teeth acute. Length 24 mm. 



Sumatra. 



Allied to M. Diarrli, G. P., but of a rather narrower and 

 more parallel form, with the clypeus less deeply emarginate, 

 the thorax shorter, more broadly rounded at the sides, with the 

 ])Osterior lobe narrower and more produced, the elytra rounded 

 and deeply serrate at the apex, the mesosternal process of a 

 different form, the spots, both above and below, lai'ger and of 

 a filvery-white colour, and the central thoracic vitta absent. 

 The only example I have seen of this handsome species is a 

 female, the habitat of which is indicated as " Palembang." 



Coptomia I'entralis. n. sp. 



Bright green, more or less tinged with blue, apex of the 

 clypeus, antenna? and legs pitchy-red with a bluish reflection, 

 femora greenish. Head with sparse coarse punctui-es between the 

 eyes, the clypeus more finely punctured^ slightly widened in front
