57. Cicadetta sachalinensis "• sp. 



Melainpsalta yezoensis Mats. ^ Ann. Zool. Jap. Vol. VI, Pt. 2, p. 104 

 (1907). 

 Allied to C. yezoensis Mats., from which it differs as follows : — 

 Body distinctly broader; face, except the sides, and clypeus black, front in 

 the middle with a very narrow ochraceous stripe; pronotum with a central ochra- 

 ceous stripe, which being interrupted near the base, on the hind margin with 2 

 small triangular concolored spots; mesonotal spots smaller; veins to tegmina fus- 

 cous, cubital and brachial veins mostly spotted with gray ; pectus and legs mostly 

 black, the latter with the apices of femora, bases of the hind tibiae, a middle spot 

 of each tarsus and some longitudinal stripes to femora, ochraceous; opercula at 

 the base broadly fuscous ; ventral black stripe much broader. 



Length — excl. tegm. % ~y-% 25 mm.; exp. tegm. % 64-$ 62 mm. 

 Hab — Saghalien (Odomari, Toyohara) ; 15 (10 ^, 5 ^) specimens were 

 collected by Prof. M. Takamatsu, Ass. Prof. M. Oguma, Messrs, I. Ada- 

 chi and S. Isshiki. It is reported that this insect is very slow in its 

 movement and easily captured by bending branch or trunk of a tree ; and 

 this character is entirely different from that of C. yezoensis Mats.
