pores with distinct raised rims, located far above the sh'ghtly prom- 

 inent carinas of segments 5, 7-17 ; antennae and legs very short and 

 stout ; copulatory legs of two simple, equal processes ; segments of 

 adult 19 ; color above black, below white ; length of female 4 mm. ; 

 width .6 mm. ; locality, mountains of Western Java, 8,000 feet. 

 This species may be considered the type of a new family, Helodes-

 Prepodesmus pictus. 



Suggesting P. tiyrinus, but the yellow areas of that species are 

 here bright ^pink ; legs and antennae very dark reddish; length of 

 male 45 mm., width 5.5 mm. ; locality, Togo Colony ; numerous 

 specimens in the BerKn Museum. 



Anisodesmus konakri. 



Nearly black, margins of all carinae yellowish ; legs and antennae 

 pinkish, rather pale ; dorsum less convex than in A. cerasinus, and 

 the posterior corners of the carinae less strongly dentate ; copulatory 

 legs not expanded at apex, but bent together at a right angle ; 

 locality Konakri, French Gambia, where I collected a pair of 

 mature individuals, January, 1896. 



Anisodesmus gracilis. 



Very distinct from the Liberian species in the smaller and more 

 slender body, and light pinkish color. Copulatory legs similar in 

 form to the other species, but much more slender apically ; length 

 of male 27 mm., width 3.25 mm. ; locality, Bismarckburg, Togo 

 Colony, Dr. K. Biittner ; Berlin Museum. 



Lipodesmus sublaevis. 



Legs and antennae moderately long ; segments faintly granular or 

 longitudinally rugulose toward the posterior margin ; pores located 

 on a distinct marginal callus projecting from about the middle of 

 anterior and middle segments ; in front of the callus is a distinct 

 notch and tooth ; posterior corner of anterior segments square, acute 

 on posterior ; copulatory legs rather robust, a s2)iniform process rising 

 from each side of the ungual portion and curved cephalad (dorsad) ; 

 length of male about 28 mm., width 3.8 mm. ; locality, Karewia, 

 East Africa, Stuhlmann ; two male specimens in the Berlin Museum. 



Scytodesmus kribi. 



Dorsum roughened with five or six irregular rows of close-set dis- 

 tinct granules ; submarginal ridge and last segment as in Oxydesvius ; 

 copulatory legs not flexed and inserted under the edge of the aper-
