59. Pselliophora haitiensis, sp. nov. 



Type.— M. C. Z. 1,888. Paratypes.— M. C. Z. 1,701. Haiti: 

 Grand Riviere: January, 1913. W. M. Mann. Four specimens 

 of which two are immature. 



In size and general appearance suggesting P. minor, but at once 

 distinguished in having the last tergite with caudal margin mesally 

 incurved. The dark stripe within the broader median dorsal pale 

 stripe is much less marked, being obscure in front of the stomal 

 region though prominent over the latter. The legs are not so dis- 

 tinctly annulate; most articles are obviously dusky over the ochra- 

 ceous background. The prefemur with dark color relieved toward 

 ends; the femur with a subdistal light annulus; the tibia dark except- 

 ing for a light ring at the distal end; tarsus dusky proximally, becom- 

 ing clear yellowish distad. 



Aside from the differences in color and size, this species differs from 

 P. pulchritarsis, also from Haiti, also in having the caudal margins 

 of sixth and seventh dorsal plates spinigerous. The concavity of the 

 caudal border of the last plate is not mesally produced as in that 

 species. 



First division of antennae composed of forty-nine to fifty-six articles; 

 the second of eighty-three to eighty-six with beyond this an incomplete 

 third division in which, in the type, eighty additional articles are 

 present and in a paratype one hundred and ninety. (In the right 

 antenna of the type there is no distinct demarcation into major 

 divisions). 



Articles of first division of tarsi from seven to nine; of the second 

 from twenty-three to thirty. 



The gonopods of the usual general structure. The second article 

 exceeding the proximal arm in length, immobile, being separated 

 only by a suture, pale, finger-like, only slightly curved. 



Length, 12.5 mm.

The generic position of this and the following species cannot be 

 determined from the descriptions. It is possible they may belong to 

 Pselliophora.
