Localities. West Greenland; Vladivostok; east Asia. 

 Body short, ovate, punctate on the dorsal surface, with minute scat- 

 tered dots; the dorsal surface of the fourth thoracic segment is orna- 

 mented on either side with an obscure suhocellate spot; the last seg- 

 ment of the abdomen is marked at the 

 base on either side with an obscure spot. 

 The front of the head is triangular, 

 with the apex widely obtuse, smooth 

 above. 



The frontal lamina is minute, narrowly 

 rhomboidal in shape. 



The eyes are minute, pentagonal in 

 shape, separated by a distance equal to 

 a third part of the width of the head. 

 The first pair of antenna? with the four 

 last articles extend beyond the anterior 

 angle of the first thoracic segment, reach- 

 ing with the peduncle as far as a third 

 part of the fourth article, and with the 

 flagellum as far as the fifth article of the 

 second pair of antennae; the flagellum is 

 composed of six articles, the first article 

 being a little longer than the second, the 

 last article being the smallest. 



The second pair of antennae extend to 

 the end of the first epimeron; the flagel- 

 lum is composed of fifteen articles. 



The first segment of the thorax is 

 slightly bisinuated anteriorly on the dorsal surface. 



The epimera are rather large, and rather wide; the posterior angles 

 of the posterior epimera are very acutely produced; the last epimeron 

 extends two parts of the length of the second segment of the abdomen. 

 The prehensile legs are short; the merus is short, and armed with three 

 or four rather stout, obtuse spines; the propodus is furnished along 

 the edge with four long, acute spines; the ungulse are rather large, 

 slender, ornamented with four carinae, somewhat incurved and subequal. 

 The ambulatory legs are rather long, rather stout, furnished with short 

 spines. The first segment of the abdomen is almost entirely concealed.
