the Cistelidas &c. of Japan. 443 



Elongate, rather obscurely green or bluish green, with 

 greyish pubescence ; the head densely and roughly sculptured, 

 somewhat opaque ; the thorax widest behind the anterior 

 margin, constricted behind ; the elytra rather long, 4-costate, 

 very slightly narrowing to the apex ; the antennae and legs 

 wholly brassy green or bluish green ; the claws palish. 



I only know the female of this species ; it differs from 

 (E. manicata in the wider head and thorax, shorter antennse, 

 and the elytra are scarcely narrowed behind. 



Hab. Junsai and Sapporo. Two examples. 



(Edemera rohusta^ sp. n. 



Elongata, cyanea ; capite thoraceque rugoso-punctatis ; antennis 



pedibusque concoloribus. 

 L. 6| mill. 



Somewhat deep blue ; the head rather wide, roughly, 

 densely and rather coarsely sculptured ; the thorax also 

 rather wide and sculptured like the head, with two transverse 

 impressions before the middle, very little constricted before 

 the base ; the elytra 4-costate, costa next the suture short, 

 scarcely reaching one third of the elytral length, thickly but 

 not quite so coarsely sculptured as the thorax, narrowed very 

 slightly and only before the apex ; the antennse relativelv 

 short, with the terminal joint pointed at the tip, and, like the 

 legs, wholly cyaneous. 



Hab. Miyanoshita and Nikko. Three examples. 



Chrysanthia viatica, sp. n. 



Elongata, parallela, pubescens ; capite thoraceque viridi-cyaneis, 

 subnitidis ; elytris aureo-cupreis vel viridi-cupreis ; antenuis 

 pedibusque nigris vel infuscatis. 



L. 6-6i mill. 



Elongate, rather narrow, parallel at the sides,, clothed with 

 short pubescence ; the head greenish or bluish green, little 

 shining, densely but not very minutely punctured ; the thorax 

 of similar colour and sculpture, longer than broad, sinuous 

 before the posterior angles ; the elytra 5-costate, golden copper 

 in colour, turning to greenish copper in a side light ; the 

 antennas and legs black or dusky brown. 



Ilab. Wada-toge, on the 1st August, 1881, in profusion; 

 Tsumago, Torii-toge, Suwaratake, and Sapporo.
