Tlie specimens examined agi-ee fairly with Karscli's desci'ip- 

 tion ; yet doubt remains as to some particulars, sucli as, liow 

 far down do the sides of the first segment reach ; how are the 

 dorsal carinas shaped ; how numerous are they, and what the 

 copulatory a])pendages look like ? ft has, theref(U'e, been 

 deemed advisable to issue a new description. 



(J mat.: length 32 m/m; diameter 3.70 m m; 34 segments ; 

 one segment apodous ; 59 jiairof legs (Fiji). 



5 mat. : length about 50 ni/m ; diameter 5.50 m/m ; 35 

 segments; one segment apodous; 63 pair of legs (Fiji). 



The gi'eat discrepancy between the measurements of both 

 specimens is accounted for by the fact that the male is a siiuill 

 contracted animal and the female a large extended sjiecimen. 



Male : — Black, anterior margin ami sides of the first tergite 

 dark brown-red ; valves dull brown-yellow; legs, antennae and 

 labrum oclii-e-yellow. 



Head sniootli, shining. Foui' labral, setiferous (lim})les. 

 Median sulcus scarcely distinct backwai'ds and even on tlie 

 upper lip, obsolete mesially. Space between the eyes about 

 twice the diameter of one of them. Eyes rounded, composed 

 of modei-ately distinct ocelli, arranged in seven series to 7-)-8 

 -f-8+7 + 64-4-1-2 = 42. Antennal sockets very shallow; 

 distance between them about equal to foui* pi'oximal jt)iuts. 

 Antenna^ short, reaching the posterior margin of the first tergite, 

 compressed as usual, slightly fhickeiied distally. The three 

 proximal joints almost bai'e ; foui'th joint with buti few distal 

 bristles; fifth and sixth gradually more pilose. Four sensory 

 cones. Micrometrical measui'ements of joints : — 1st joint 

 0.384 m/m ; 2nd, 0.512 m ni ; 3rd, 0.416 m/m ; 4th 0.352 

 m/m; 5th, 0.352 m/m : 6th, 0.448 m/m; 7lh and 8th, 0.09(> 

 m/m; total length 2.560 m/m. Diameter of 2nd joint 0.336 

 m/m; of 6th, 0.384. Mandibular stem (pleura*) with the 

 inferior angle somewhat pointed.
