the Cistclidse &c. of Japan. 277 



the thorax is rounded off anteriorly, the body is similarly 

 hirsute, and the last joint but one of the antenna? is short, 

 like that of the Fabrician species. 

 Hah. Sapporo. Two examples. 



Arthromacra viridissimaj sp. n. 



Elongata, viridissima, nitida, punctata ; antennis pedibusquo flavis 



vel obscure flavis. 

 L. 9-12 mill. 



Elongate, bright metallic green, densely punctate above; 

 the head, eyes rather small and rather prominent, with a semi- 

 circular raised process over the point of the antennal insertion, 

 coarsely and densely punctured, surface somewhat uneven ; 

 the thorax punctured like the head, cylindrical, truncate 

 before and behind ; the elytra nearly as wide again as the 

 thorax, punctate, with the punctures inclined to be transversely 

 confluent, apices obtusely acuminate ; the antenna, terminal 

 joint as long as the eighth, ninth, and tenth together, testa- 

 ceous,with terminal and ninth and tenth joints sometimes intus- 

 cate, basal joint also sometimes dusky on the upper surface; 

 the legs testaceous, with airical portion of the femur broadly 

 green, and the base of the first tarsal joint narrowly dusky, 

 claws and apical parts of all the tarsi also dusky. Very 

 rarely the legs are wholly pale yellow. The last joint of the 

 palpus is infuscate. 



In Arthromacra cenea, Say, the elytral stria? are obscurely 

 traceable ; in the Japanese species there are no indications ot 

 strige. 



Hab. Miyanoshita, Oyama, Tokio, Nikko, and Hitoyoshi. 

 This pretty species is common in certain places in May, 

 occurring in the flowers of Deutzia and Cerasus. 



Arthromacra sumptuosa, sp. n. 



Elongata, purpureo-cuprea, nitida ; antennis pedibusque obscure 



nigris. 

 L. ^-l^ mill. 



This species closely resembles A. viridissima in sculpture, 

 but the colour is wholly different. In structure it differs in 

 having shorter and more robust antenna?, joints 7-10 being 

 somewhat obconical, not elongate ; the thorax is shorter and 

 less cylindrical, with the outline nearly quadrate when viewed 

 from above and the elytra are less acuminate at the apices ; 

 the legs and antennae wholly and obscurely black. 



Bab. Chiuzenji. A})parently scarce and local. Six ex- 

 amples.
