in the shape of the head, which is more quadrate ; the eyes are 

 always placed heyond the median part ; the prothorax has no 

 median sulcus ; the elytra no discoidal striae ; the abdomen is 

 entirely without margin, and the first segment is very large, and 

 the others abruptly declivous. 



The head of the male bears generally some foveas, spines, or 

 tubercles ; the shape of the elytra is different from that of the 

 female, the shoulders being more or less prominent in the male, and 

 rounded and obsolete in the female. 



Both Arthmius and Syrbatus are largely represented in America, 

 and the finding of this genus in South Africa was quite unexpected 

 and is of great interest.

 likewise the legs, body covered with a brief fulvous pubescence ;

 decreasing in length, eighth quadrate, ninth to tenth larger than the 

 others, subquadrate, eleventh large, truncate at base, ovate, acumi- 

 nate ; prothorax narrower than the head, cordate, and having two 

 lateral sulci and a transverse one, angular in the middle, base im- 

 pressed on each side ; elytra a little longer than broad, slightly 

 rounded laterally, shoulders oblique, somewhat prominent, base 

 trifoveate ; abdomen a little shorter and narrower than the elytra ; 

 first dorsal segment foveate on each side but neither deeply nor 

 broadly ; legs strong, tibiae slightly incurved, the intermediate ones 

 have a minute apical spur ; metasternum deeply depressed, last 

 ventral segment strongly impressed. Male. Length 1-80-2 mm. 



Several males have been captured near Salisbury, but no females ; 

 the latter probably remain at the roots of grass, while the former 

 were caught flying at sunset in their search for a mate.
