the lateral processes distinctly directed upwardly, their apices

Xiphistes inermis, Jacobi, in Sjcistedt Kilimandj. Exped. xii., Horn, 

 p. 119, t. ii. fig. 7 (1910). 



Jacobi described his species from a single $ specimen 

 which measured " long. c. tegm. 5,5 mm." The British 

 Museum now possesses a single female specimen, collected by 

 H. S. Stannus at Zomba, Nyasaland, which measures 8^ mm.

 tegminal margin ; pronotal angles very robust and prominent, 

 obliquely directed upwardly, their apices truncate, all their 

 margins ridged, outwardly a little sinuately narrowed near 

 base, pronotum centrally percurrently ridged, posterior process 

 moderately slender, rugulose, beneath centrally distinctly 

 serrate, its apex subacute, recurved, passing the posterior 

 angle of the inner tegminal margin; tibiae distinctly dilated. 



Long., inch ant. pronot. proc, 8^ mm.
