Bartica, British Guiana. II, 12, 1913. (H. S. Parish.) One 

 male. [A. N. S. P.] 



Peruvian Maranon. One male, type. [M. C. Z.] 



Chanchomayo, Peru, 1000 meters elevation (two specimens.) 

 Two with no date; others II and V, 1910. Three males, t\v<> 

 females. [A. N. S. P.] 



As we have said above, the type of Scudder's species is be- 

 fore us, a unique male, and there is no doubt in our minds as 

 to the synonymy of Brunner's fastigiosus. Brunner's Sleiro- 

 donopsis (sic) scudderi, from the Province of Sara, Bolivia, 

 appears to us to be only a small specimen of bilobata ; in fact, 

 the Bartica male here recorded is but faintly larger than his 

 measurements. The material before us would fully fit his de- 

 scription. Regarding Bolivar's Posidippus brunncri 1 ' we can- 

 not speak with such certainty, as the description is not as con- 

 clusive. It is certainly very close, if not identical, with the 

 present species. 



The number of spines on the dorsal margins of the median 

 tibiae vary considerably in this species, often greatly on the 

 two limbs of the same individual. Our specimens show the 



following count :

The range of the species is almost covered by the records 

 given above. The previous records were all from the upper 

 Amazonian region, except the certainly erroneous Quito one, 

 upon which we have already commented, and B rimer's records 

 of the synonymic scudderi and fastigiosus from the Province 

 of Sara, Bolivia.
