species a single row of pointed teeth is found along the inner lower 

 edge, which begins near the base and extends over the distai two 

 thirds, f. inst. in G. airata Stol. (6, p. 495); the row is rather short 

 in the male of G. fragttis With as seen in fig. 1 (p. 12). In the one 

 specimen of Marfhana vestita n. sp., the tarsus was provided with 

 a row of about 30 teeth, while in the other specimen the row contains 

 about 15 teeth, as seen in fig. 2 (p. 12). With regard to the structure 

 in G. aenescens T hor. and G. splendens With I refer to (0, p. 473). 

 In a few species we fìnd an inner, more proximal row of several 

 teeth, and an outer, more distai row with a few teeth, f. inst. in G. 

 flavimaculaia With (p. 499), G. iriangularis With (p. 500) and G. ìm- 

 perator, var. dentata With (p. 502). G. triangularis With (fig. 3, p. 12) 

 has an inner row, the basai portion of which contains several teeth, 

 densely placed, while the distai portion has only a few teeth, rather 

 remote from each other, as well as an outer, more distai, consisting 

 of about ten teeth, well separated from each other. The tarsi of the 

 male of G. imperator, var. dentata With (6, p. 502) bear not only « an 

 inner row of about 20 teeth», but also more distally and exteriorly 

 about fìve teeth, far apart from each other. In G. sarawaliensis n. sp. 

 we fìnd an other arrangement (fig. 4) ; there is an inner row of about 15 

 teeth, which begins near the base and extends to the middle, as well 

 as an outer one, the four teeth of which are placed rather apart on 

 the basai third of the tarsus. 



B. On the Genera of the Gagrellinae Thor. 



The discussion of this theme in my above-quoted paper (p. 474) is 

 rather too short and not quite easy to follow ; I am, moreover, inclined 

 to think, that a new treatment of this topic may be useful, because 

 I in that paper had no opportunity of discussing the position of Ver- 

 pulus Sim., and had then not yet examined any specimen of Mar- 

 ciana Thor. 



The genus Verpulus Sim. is. according to Simon, (5, p. 84) nearly 

 related to Hypsibunus Thor., but « differt tubere oculorum reclinato, 

 angusto, sed apice leviter ampliato omnino mutico et laeve, et pedibus- 

 maxillaribus simplicibus, patella convexa intus haud producta ramulo 

 carente et tibia patella haud longiore >. The first characters, taken 

 from the sloping and shape of the tuberete, have probably only spe- 

 cific, but scarcely any generic value whatever. The caracter, which 

 the dentition of the tubercle provides, can scarcely be claimed to be 

 of great importance in the definition of a genus, when we take into 

 consideration, that the armature of this organ is variable in a con- 

 siderale degree even within the same species; f. inst. in Hypsibunvs
