PACHYBOLUS MACROSTERNUS, new species. 

 (Plate LI, figs. 3rt-3rf.) 



Type.— 1^0. 77l\ TT.S.N.M. 



Locality. — Congo. 



Length, about 135 mm.; width of male, 14.5 mm, at segment 65 

 number of segnuMits, 52, 



Color of alcoholic specimens nearly black, possibly owing to discolora- 

 tion. The transverse red bands are distinct on examination, but the 

 colors of all the i)arts seem to be darker than in other species. 



Copuhitory legs with sternum very large, both longer and broader 

 than in the other species; the form of the tlagella is more nearly tliat 

 of ]\ hraehysternu.s, but they are distally much narrower and more 

 simple than in that species, with a distinct tendency in the direction of 

 trrtiiN and tof/ocnsis^ but with numerous folds, wrinkles, and appressed 

 lamella' which do not appear in those species. 



Three male specimens of this species are in the United States 

 National Museum, They were collected by the Ivev. ,). 11, Camp in the 

 Congo Free State, probably in the vicinity of Leopoldville, They were 

 in the same jar with the specimens of the preceding species. 



PACHYBOLUS TOGOENSIS, new species. 

 (I*liit<' L, lig.s. 2a-2c.) 



Ty2)e.—^o. liOG7, Berlin Museum, 



Locaiily. — Togo Colony . 



Length, 155 mm,; greatest diameter of male, 14.5 mm. at segment 6; 

 number of segments, 54. 



Color of alcoholic specimens nearly black, the anterior subsegments 

 dark red above, tinged with brown in the vicinity of the pores, but 

 continuing somewhat reddish even on the ventral surface, 



Coi)ulatory legs similar in structure to those of /*, tectiis from Zanzi- 

 bar, but more robust throughout in the i)osterior pair; the terminal 

 lobe which bears the seminal aperture is also much larger than in that 

 species. 



Two male specimens in the Berlin Museum were collected in the 

 wooded region of the interior at Misahohe (Baumaun). 



From geographical considerations it might be suggested that /*. 

 toyoensis would be likely to turn out a synonym of one of Newport's 

 species, but the occurrenc(M>f i*. liynlatus atCirand Popo indicates that 

 the latter species is distributed along the coast, as Pocock has implied 

 in his treatment of the synonymy. 



The nearest relationshi]) of this species as shown by the tbrm of the 

 copuhitory legs is with /'. iectii.s from Zanzibar, the apices of the parts 

 in question being (piite dill'erent from those of other West African 

 species.
