202. CUBODESMUS LATIOR, Sp. nOV. 



Type. — M. C. Z. 4,515. Cuba: Guantanamo, La Hembrita, 

 Mt. Toro. Paratype. — M. C. Z. 4,516. Cuba: Los Hondones, La 

 Union, Mt. Libano. C. T. Ramsden. 



This is a larger species than the preceding. It is readily distin- 

 guished from that species in the uniformly rectangular caudal corners 

 of the keels of all excepting the last few somites in which they are 

 produced as usual. In contrast with C. ramsdeni, the processes of the 

 eighteenth tergite are longest and much more strongly exceed those of 

 the nineteenth. A lateral tooth occurs on each side of only the second 

 to fourth tergites inclusive, those of the second minute, the others 

 distinct. In a paratype all lateral teeth obsolete. Cauda less de- 

 curved. 



Type, which is not in full color, with yellow keels, the dorsum brown 

 elsewhere. Ventral and pleural regions and appendages yellow. 



A paratype from Los Hondones has the dorsum deep black except- 

 ing the keels and a pale stripe along caudal borders of tergites. The 

 black of head continues between antennae and widens but little 

 below as a small circular area. 



The terminal processes of the third sternite similar to those in 

 C. ramsdeni, but more conical. 



In the male gonopods the femoral division is longer and propor- 

 tionately more slender. 



The principal or ventral (caudal) branch is much more strongly 

 bent ectad at base; geniculate. The terminal processes are somewhat 

 similar but the erect distal one is shorter, while the principal or dorsal 

 one instead of remaining of uniform width with the tip rounded and 

 straight, is strongly narrowed, with the tip acute or very narrowly 

 rounded and strongly curved ventrad. 



Length (male type), about 42 mm. ; width close to 7 mm. 



203. CuBODESMUs PROXIMUS, sp. nov. 



Type.— 'M. C. Z. 4,517. Cuba: Guantanamo, Mt. Toro, Ramon 

 el Moro, Nimfilas, May 2, 1914. C. T. Ramsden. 



This species is very close in general structure to C. latior, but differs 

 in details of the male gonopods. The central distal process of the 

 principal branch and the lower (seminiferous) process are shorter and
