the Cistelidfe (fee. of Japan. 437 



short inconspicuous carina before the middle of the neck, 

 constricted behind the eyes, mouth-organs reddish testaceous ; 

 the thorax longer than wide, widest a little behind the neck, 

 scarcely narrowed behind, sculptured like the head, with 

 three shallow ill-defined impressions — one before the scutellum, 

 one on each side of the widest part ; the elytra densely 

 sculptured and somewhat opaque, lateral costa complete and 

 well-raised, the next less elevated, and the third again is less 

 conspicuous ; the antenna dull reddish brown, two basal joints 

 darker; the legs same colour, femora darker, tibia3 bispurred. 



I think I am right in assigning this curious species to 

 Xanthochroa ; it has the facies somewhat of the female of 

 Oncomera venosa. 



Hah. Sapporo. One female example. 



Xanthochroa Hilleri, Harold. 



" Eufo-testacea vel lurido-testacea ; antennis basi, femoribus antice 

 apice, posticis cum tibiis omnino fere fuscis ; cJ femoribus anticis 

 crassioribus." 



L. 11-131 mill. 



Five basal joints of the antennee usually infuscate, the 

 others reddish brown. 



Bah. Osaka, Shiukano, Junsai, and Sapporo. Occurs in 

 July and August. 



Xanthochroa luteipennis^ Mars. 



This species may be recognized from the others of this 

 series by its having yellowish-brown elytra, but being other- 

 wise entirely black,

Eobia, Semenow, Hor. Soc. Ent. Ross, xxviii. p. 455, nota (1894). 

 This genus is founded to receive : — 



Asclera cinereipennis ^Wot&ch.. Bull. Mosc. p. 173 (1866). 

 Ananca japonica, Har. Abh. Brem. p. 133 (1876). 

 Sessinia japonica^ Har. Deutsch. ent. Zeitschr p 82 

 (1878). 



Sessinia remained uncharacterized until 1894 ; the type is 

 now livida, F. Ananca is a name proposed by Fairmaire in 

 1863, but not yet characterized. The genus Nacerdochroa 

 Reitt. Wien. ent. Zeit. xii. p. 113, 1893, is very close 

 indeed to Eobia ; it has the same constriction in, or false joint
