 trochanters unarmed and femora only scattered with very small 

 granules. Number of the tarsal segments : 6 ; 11 ; 7 ; 8. There are

 much sprinkled with the same colour. Also the transverse grooves 

 of the abdominal scutum as well as the point of the two thorns of

10. Macrobunus singularis, Roewer. 



5 specimens (2 cf , 3 $ ) : Kobo (400 ft.), 30-xi-i9ii, from rotten

II. Macrobunus longipes, sp. nov. 



I specimen: Upper Rotung {ca. 2000 ft.), 6-i-i9i2, under 

 leaf-stem of plaintain. 



Measurements in mm.: body 5-5 ; ist leg 18; 2nd 35 ; 3rd 24;

Differing from Macrobunus singularis, Rwr., only in the fol- 

 lowing particulars: 



Measurements of legs comparatively much longer and more 

 slender than those of the allied species ; number of segments of the 

 tarsi : 7; 12; 10; 11. 



Colour of the cephalothorax and of the e^'e-tubercle uni- 

 colourous pale yellowish, also the median region around the two 

 cones of the abdominal scutum, which is on the lateral and 

 posterior margins almost black, thus surrounding on either lateral 

 margin of the abdominal scutum one very white trilobate spot. 

 This spot is much larger than that in Macrobunus singularis, Rwr.
