General color from li^ht ferruginous to dark ferruginous and deep brown. 

 Sometimes a series of obscure blackish dots along each side of dorsum or these 

 more or less fused Antennae fulvous. 



Head deep, stout. Rostrum exceeding the head in length, extendu 

 little beyond distal end of Bixth antenna! article Antennae long, of usual 

 form, sixth article narrowing moderately distad, the seventh small and form- 

 ing a rounded apex to the sixth. 



Collum with anterior margin a1 middle forming a very obtuse reentrant 

 angle; lower margin convex, often extending a little below level of lower 



edges of succeeding ones; anterolateral corner widely convex; aboul equalling 



the two succeeding somites together in length. 



Dorsum densely clothed with hairs as usual, those of body of uniform length 

 but those on front of head longer. 



Posterior margin of pleurites evenly convex; mesal margin incurved, the 

 caudal lobe larger than the anterior, the edge of the latter nearly straight, 

 that of the other rounded. 



Number of segments, forty-five to fifty-five. 



Length, 11 mm.

Type.— M. C. X. 4,977. Solomons: Wainoni Bay (W. ML Mann). 



Fulvous of light ferruginous cast. Antennae yellow. 



Aside from coloration and being a smaller and much more slender 

 form, the present species differs in various other characters from 8. 

 obxeurior. The head is somewhat more slender, less abruptly narrowed 

 in front. The rostrum long and curved, much exceeding the head and 

 extending to near distal end of sixth antenna] article. Antennae 

 more slender; the sixth article less narrowed distad, nearly strictly 

 cylindrical. 



Anteroventral corner of collum less oblique but well rounded. Col- 

 lum a little longer than the two succeeding tergites together. 



Differing in structure of male gonopods, e. g. the distal division of 

 the anterior pair notably longer, extending forward to near the 

 anterior border of the sixth somite, with the transparent, blade-like 

 distal end more abruptly bent ventrad, subgeniculate instead of evenly 

 curved. 



Number of somites, seventy-five. 



Length, about 7.5 mm.
