of the black pubescence ojn the thorax and abdpmen, so characteristic 

 of this species or others in the subgenus. Tkerioptectes. From the 

 comparison with T. tarandinus from Norway, I could not find even 

 the slightest difference, and I am obliged to, determine that karafuto.ni* 

 is an undoubtful synonym of the former. . -.-..,

Small though rather broad black species with two shining black- 

 ish frontal calli, with a distinct brownish ocelligerous tubercle, with 

 three dorsal ashy grey stripes composed of rather large long-triangular 

 spots, and with white pubescent eyes. 



Female. Head very short, slightly broader than the thorax, 

 and slightly arched. Frontal stripe contracted from the vertex to the 

 front eye-angles, four times as long as its broadest part or four 

 and a half times as long as its narrowest part, a'shy grey though 

 greyish yellow at a large middle part, except the more or less narrow- 

 ly furrowed middle stripe shining black ; lower frontal callus shining 

 brownish black quadrate (though with roundish angles) about as long 

 as wide, moderately raised forwards, not quite touching the eyes, and 

 hardly continued upwards in a narrow slightly elevated blackish line which 

 represents the upper callus ; upper callus about the upper half furcate by 

 a narrow median furrow which reaches just below the ocelligerous tubercle, 

 so as even slightly denuded specimens the frontal callus and ocelligerous 

 tubercle are quite continued ; vertex pale yellowish grey, with a distinct 

 though rather small oblong (or sometimes duplicate) shining brown 

 ocelligerous tubercle ; pubescence on the frons black, rather abundant
