4 PBOCEEDINGS OF THE NATIONAL, MUSEUM. vol.61. 



NESOBOLUS YATERUS, new species. 



Plate 2, figs. 5-10. 



This species very much resembles N. toroanus Chamberlin in its 

 general coloration and structure. The most obvious difference in col- 

 oration is that in the present species the legs are yellowish whereas 

 in all the adults of toroanus examined they are distinctly ferruginous. 



The markings of the somites in general the same, the suture being 

 deeply impresed throughout on the typical tergites ; but the suture of 

 the second segment is absent or weakly developed only on the sides. 

 On the contrary, in toroanus the suture of the segment is distinct 

 throughout. 



Processes of third, fourth, and fifth legs especially prominent, 

 much as in toroanus (see pi. 2, figs. 7, 8). 



The species may be distinguished by the form of the minor prong 

 of the posterior gonopods. In toroanus this is abruptly bent ventrad 

 near its middle and then a little caudad at its tip (pi. 2, fig. 4) . On 

 the contrary, in yaterus this prong is but weakly evenly curved as 

 shown in plate 2, figure 6. The form of the anterior gonopods is 

 shown in plate 2, figure 5. 



Number of segments, 46-48. 



Length, up to near 35 mm. ; width, 3 mm. 



Locality.— Cuh^i: Oriente Province, Yateras, Bella Vinta (May 4, 

 1907) (Type locality), and Jaguey (April 20, 1907). W. R. Maxon 

 collection. 



Type.— C^it. No. 858, U.S.N.M. 



NESOBOLUS LIBANONUS. new ipecies. 



Plate 2, fig. 11 ; plate 3, figs. 1-5. 



Resembling toroanus but the legs pale yellow, not ferruginous. 

 The type differs from those of the other two laiown species in having 

 the process of the third joint of the fifth legs of male much smaller 

 than those of fourth leg and almost obsolete (see pi. 3, figs. 1-5). 

 The minor prong of the posterior gonopod is bent more than in yate- 

 rus but obviously less than in toroanus (see pi. 2, fig. 11). The 

 minor prong at its end is in contact, or nearly so, instead of being 

 well separated as it is in yaterus^ as shown in the figure. 



Anterior gonopods essentially as in yaterus. 



Number of segments, 46. 



Thickness, 2.5 mm. 



Locality.— Cuba : Alto de la Union, Mount Libano. May 18, 1913 

 (C. T. Ramsden). 



Type.—C&t No. 5035, M. C. Z.
