50 KATYDIDS (TETTIGONIIDAE) OF SARAWAK MUSEUM. 



I am not absolutely sure that I have the same species before 

 me as Bolivar, but I find it still very probable. At all events, 

 I give here figures of the cf genitalia of one of the Bornean 

 specimens before me. In every case this species differs by 

 these characters from both E. distincta Eedtenbacher and 

 E. mirahilis Karny, whilst it agTees with them by its hind 

 tibiae distinctly spined beneath in the apical half, which were 

 described by Bolivar as unarmed in E. teuthroides. Hebard 



(1. c), however, stated : "The caudal tibiae are in the 



topotypic material before us armed dorsad with small spines 

 and ventrad, except in proximal portion, with slightly larger 

 spines, distad with three pairs of spurs. The male before us 

 agrees so closely in every other detail with Bolivar's description 

 that we are convinced "femora" instead of "tibiae" was 

 intended. Thus E. distincta appears to be separable mainly 

 by its smaller size, unarmed mesosternum and by male 

 genitalia differences." Therefore, I think the arming of hind 

 tibiae in the material before me to be no reason for separating 

 it from teiitJiroides. as the mesosternum is distinctly bituber- 

 culate in both.
