Body oblong-ovate, twice as long as wide, \\ mm. : 9 mm. Abdo- 

 men abruptly narrower than thorax. 



Head twice as wide as long, 1 mm.: 2 mm., with the anterior mar- 

 gin slightly convex; antero-lateral lobes small. The eyes are small, 

 composite, and situated at the base of the antero-lateral lobes. The first 

 pair of antennte are small and inconspicuous. The second pair have 

 the first article short; the second is twice as long as the first; the third 

 is equal in length to the second; the fourth is twice as long as the third; 

 the fifth is one and a half times as long as the fourth. The fiagellum 

 is composed of two articles, the first of which is twice as long as the 

 second, and both taken together are almost equal in length to the fifth 

 article of the peduncle. The second antenna extend to the posterior 

 margin of the fourth thoracic segment. 



The first segment of the thorax is perhaps a little longer than any 

 of the others, which are subequal. The antero-lateral angles of the 

 first segment are produced forward to surround the head, and they 

 extend to the base of the antero-lateral lobes of the head. The epimera 

 are not distinctly separated from the segments. 



The al)domen is abruptly narrower than the thorax. All six seg- 

 ments are distinct. The first two have the lateral parts covered by 

 the seventh thoracic segment. The third, fourth, and fifth segments 

 have the lateral j)arts small, not greatly expanded. The sixth or ter- 

 minal segment is triangular in shape. It is 1 nun. wide at the base and 

 is hardly more than \ mm, long. The apex is acute, and there is a 

 slight con(mvity in its dorsal surface. The basal article or peduncle of 

 the uropoda is not longer than the apex of the t(>rminal abdominal 

 segment. The outer branch is \\ mm. long and extends its entire 

 length beyond the apex of the terminal abdominal segment. The inner 

 branch extends about one-third the length of the outer branch. 



All the legs are ambulatory in character.
