CuBOBOLus, gen. nov. 



Unlike Microspirobolus and Cairibolus the median plate in the male 

 gonopods is relatively narrow, and is distally acute or very narrowly 

 rounded, leaving the paired gonopods much exposed at the sides in 

 front view. The anterior pieces of the first gonopods are broad and 

 bifurcate distally, the anterior branch wide and thin, the posterior 

 extending mesad behind the telopodite which it thus embraces. The 

 ■ inner or posterior gonopod distally expanded into a plate-like body 

 which is distally excised and bears above the notch a thin subacute 

 process; from near the base of the expanded end piece arises a slender, 

 distally acute, process or style which lies close to the end-piece and 

 terminates near the tip of the latter. 



Articles of antennae all short, none specially enlarged; sensory 

 cones four in number. Labial pores 2 + 2. 



Pores beginning on sixth somite, situated in front of sutures. No 

 scobina. 



Anal valves not compressed or margined. 



Genotype. — C. heliganus, sp. nov. 



140. CuBOBOLUS BELIGANUS, Sp. UOV. 



Type.— ^l. C. Z. 4,418. Paratype.— M. C. Z. 4,419. Cuba: 

 Oriente Province, Belig, near Cape Cruz. O. Tollin. 



General color brownish, when in full color chestnut or red caudad 

 of the suture on each somite, and the area in front of the suture em- 

 bracing numerous light dots as viewed under the lens. The anal 

 scutum and valves in the type are a dull dark yellowish color. The 

 labrum light below excepting a narrow marginal stripe below which is 

 dark. Head elsewhere darker excepting across vertex at base. Legs 

 flavous or light brown. 



Ocelli about thirtj^-two in number in each eye, these in six trans- 

 verse and somewhat curved series. 



Collum widely rounded laterally, only vaguely margined below. 

 Second tergite extending much below it, not flattened or excavated 

 beneath. 



The segmental sutures deep and distinct entirely across dorsum, 

 either straight or but slightly curved at level of pore, the latter close 

 to the longitudinal suture which is distinct.
