VOL. 72 



Last segment subtriangular, exposed above. 



Legs short and with large coxal joints, separated by the broad 

 sterna which are narrower and more elevated behind ; first and second 

 pairs of legs conspicuously smaller and more crassate than those fol- 

 lowing, with the claws also reduced. 



BUZONIUM CRASSIPES, new species 



Number of segments from 52 to 72; length of largest specimen 

 21 mm., width 2.8 mm. Dorsum strongly convex ; body cavity hardly 

 twice as wide as high; body very abruptly rounded behind, more 

 gradually in front. 



Alcoholic specimens with the dorsum pinkish brown, the sides 

 lighter, ventral surface pale. The semitransparency of the exoskele- 

 ton allows the internal organs to affect the color of the dorsum.

 terior VIEW. b. First legs of male, posterior view. c. Segments 4, 5, 6, 



AND 7, LATERAL VIEW. d. LAST THREE SEGMENTS, DORSAL VIEW 



Head with the clypeus and labrum greatly widened and rounded 

 and with numerous very short, stiffly erect hairs ; labrum considerably 

 broader than the distance between the base of the antennae, the 

 margin coarsely serrate on the sides, more finely in the middle ; vertex 

 and front roughened by rather deep and somewhat irregular length- 

 wise impressions ; eyes very widely separated, not hidden by the first 

 segment, composed of two ocelli each, placed quite obliquely; anten- 

 nae subclavate and as long as the width of the first segment, first and 

 second joints together equal in length to the sixth, which is the 

 longest; sense cones 4.
