JAPANESE CICADIMi

as tsitkittsukubosìii. Its ground color is black, while the yellowish green 

 markings differ very much according to individuals. Its description is 

 as follows : — 



" Head and thorax above ochraceous ; head with its lateral 

 striations and a spot near base of front, the area of the ocelli, and a large 

 irregular lateral fascia in front of eyes, black ; pronotum with two 

 central black fasciae somewhat hour-glass shaped, the furrows, a spot near 

 each lateral angle of posterior margin, and the extreme lateral margin, 

 black ; mesonotum with five large black fasciate spots, of which two are 

 obconical with their bases on the anterior margin, one large central 

 and subtriangular, and one somewhat broken occupying each lateral 

 area ; abdomen above blackish, the tympanal coverings ochraceous. 

 Head beneath sternum, legs, and opercula ochraceous ; apices of anterior 

 femora, the apices of the tibiœ and tarsi, the transverse striations 

 and longitudinal sulcation to face, and the margins of the opercula 

 black ; abdomen beneath castaneous, apex pitchy. 



" Tegmina and wings pale hyaline, the venation brownish ; tegmina 

 with the costal membrane brownish-ochraceous, the transverse veins at 

 the bases of the second and third apical areas fuscated. The opercula 

 are short, narrowed and angulated at apices, and reach the third ab- 

 dominal segment. 



" Long. excl. tegm. ^30 mm. Exp. tegm. 82 mm." 



It comes out in late summer or early autumn, and for this reason 

 the Chinese call it " winter cicada," it being the forerunner of winter. 

 It is very hard to catch on account of its agility, but at the time of 

 oviposition it seems to become very sluggish. Its screamings are heard 

 at first far up on high trees or in mountain regions, but gradually it 

 comes down, and abounds near human habitations and so becomes 

 familiar to all. 



In Hokkaido specimens are much smaller and the species is here 

 more local, it specially prefering regions where willows abound, the 

 latter being probably its food plant.
