the sixth aud fifteenth segments. The spine which stands at the base 

 of the flagelhiin in front is much smaller than in stellifer, while the 

 flagellum is provided with a sharp, proximally directed spine at the 

 base of the small subapical expansion which appears in both species. 



The Berlin Museum possesses a considerable number of specimens 

 closely comparable with that collected by Stuhlmauii at Dar es Salaam. 

 These are labeled '■'■ Zwischen der KUste imd Kilimandsoharo^^ (flohnel); 

 " Madinula; " " Tana" (Neumann). 



ASTRODESMUS STRIATUS, new species. 

 (Plate LXI, fig. 3a.) 



In habit and coloration resembling ^1. stellifer, but smaller, and dif- 

 fering from that and all other species in having the dorsal surface of 

 the segments distinctly striate longitudinally in addition to being some- 

 what strongly rugulose. 



Copulatory legs most closely similar to those of A. stellifer, but with 

 the distal expansion and its attendant spines somewhat shorter than in 

 that species. The stout spine at the base of the tiagellum is larger 

 than in A. stellifer, though scarcely equal to that of laxus and rohustus. 



Length of male, about 45 mm.; width, 11.5 mm. 



Locality. — East Africa; type in the Berlin ^Museum. 



ASTRODESMUS PETILUS, new species. 

 (Plate LXI, figs. 6a-6d.) 



Vertex evenly convex, tlie sulcus rather shallow, the suture without 

 hairs. 



Olypeus with a i)air of widely separated punctations somewhat below 

 the antennal sockets, and several others above the labrum. 



Autenntc filiform, slender, the distal joints moderately hirsute with 

 short hairs. 



First segment with marginal callus distinctly longitudinal, as on the 

 following, there being a distinct lateral side. 



Segments dorsally finely rugulose-coriaceous, more distinctly so upon 

 the carina:;. 



Lateral carinte with distinct anterior and posterior margins; mar- 

 ginal callus with mesial edge nearly straight; on poriferous segments 

 the callus is widened laterally, so that the carinje appear more rounded 

 than on the poreless segments. 



Kepugnatorial pores rather large, facing dorso-laterad, placed in a 

 shallow depression and surrounded by a fine raised rim; the widening 

 of the callus opposite the pore is sometimes rather abrupt, so that the 

 edge behind it appears slightly emarginate. 



Below the carina; the segments are finely rugulose with distinctly 

 tuberculate secondary carinas. 



Anterior subsegmeuts very finely coriaceous; transverse constriction 

 distinctly crenulate; supplementary margin of moderate length; the
