These specimens have the second segment of the abdomen 

 nearly or quite three times as long as broad, indicating a 

 relationship with the genus Dyme rather than Libethra. But 

 they agree with the description of L. rollei and Brunner in- 

 cludes it in his key to the species of Dyme as well as that of 

 Libethra, showing that he also recognized its relationship to 

 both these genera. 



There is some variation in the measurements of these four 

 specimens, the fore femora varying from 16 to 19 mm. in 

 length.

 monograph^ to L. rugosa Brunner, but it possesses several 

 characters separating it from that species as described by 

 Brunner, the most obvious one being the ventrally lobed 

 femora. Nor does the description of rugosa mention the 

 prominent dorsal flange in the posterior margin of the sec-
