the tliorax is rounded otf anteriorly, tlie body is similarly 

 hirsute, and the last joint but one ot" the antennaj is short, 

 like that of the Fubrieian sjjecies. 

 IJab. Sapporo. Two examples. 



Arthromacra viridissima^ sp. n. 



Elongata, viridissima, nitida, punctata ; antennis p('di}ius(|iic tlavis 



vol obscure tlavis. 

 L. 9-ll> mill. 



Elongate, bright uietallic green, densely punctate above; 

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

 circular raised process over the point of the antennal insertion, 

 coarsely and densely i)unctured, 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 sometiuu^s dusky on the upper surface ; 

 the legs testaceous, with apical 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 tlie 

 palpus is intuscate. 



In Artlirornacra irnea, Say, the clytral stri;e are obs.;urcly 

 traceable; in the Japanese species there are no indications ot 

 striag. 



Ilab. Miyanoshita, Oyama, Tokio, Nikko, and llitoyoshi. 

 This pretty species is common in certain places in May, 

 occurring in the flowers of Ututzia and Cerasus. 



Arthromacra sianj)tuosa, sp. n. 



Elonpata, purpuico-cuprca, nitida : antcniiis pcdibusciuo obscure 



nigris. 

 L. 9|-J0i 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 antcniuu, 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. 



ilab. Chiuzenji. A]iparrntly scarce and local. Six ex- 

 amples.
