This species is peculiar to Japan, and the only known representa- 

 tive of the genus. It is very common on the Main Island and in Kyukyu, 

 but much less so in Hokkaido. It is commonly known as aburazemi. 

 Its description is as follows : — 



" Head black ; apex and base of front, anterior lateral margins, 

 a small spot behind eyes, and two large discal spots to vertex 

 castaneous ; ocelli and eyes ochraceous. Pronotum castaneous, the 

 anterior and posterior margins, and two narrow central longitudinal 

 fascia?, blackish ; extreme lateral margins castaneous. Mesonotum 

 black, with 2 faint obconical spots at centre of anterior margin ; in some 

 specimens there are a few castaneous spots ; cruciform elevation casta- 

 neous, with its centre and apical angles black. Abdomen above black. 

 Body beneath ochraceous, mottled with dark castaneous and blackish ; 

 opercula dull ochraceous, the outer margin and a subapical fascia 

 castaneous, a small pale spot near apex of lower apical area." 



Long. excl. tegm. 30-37 mm. Exp. tegm. 92-118 mm. 



The females of this species are invariably larger than the males, 

 just contrary to what is known in the other species ; and on examina- 

 tion each contains, according to Mr. Nawa, on the average 349 long, 

 slightly curved eggs. It cries from morn till night, but chiefly towards 

 evening at sunset. It continually changes its place ; sometimes resting 

 upon the telegraph-pole ; sometimes on the fence and at others on 

 bamboos, etc. This, like the preceeding species, is very common and is 

 easily distinguished by its reddish brown wings.
