scales ; scutellum densely scaly ; elytra also densely scaly, the scales 

 elongated, sub-lanuginose and not unlike appressed squamose hairs ; 

 these scales are greyish or sub-flavescent, those with which the 

 abdomen is densely clothed are almost similar in shape, but on the 

 pygidial part they are normally rounded and more flavescent ; hind 

 claws double and both cleft. 



Female : Like the male, but the pygidial part is scaly. 



Length 34-4i- mm. ; width 2-2-|- mm. 



Hah. Cape Colony (Port Elizabeth, Uitenhage). 



Omocrates misellus, n. spec. 



Female : Black, with the elytra pale flavous, legs rufescent ; 

 clypeus quadri-dentate, but with the four teeth equal but not strongly 

 developed ; prothorax clothed all over the surface with long, greyish 

 white villose hairs, it has in the centre a deep, median sulcus reaching 

 from base to apex ; scutellum with squamose greyish hairs ; elytra 

 covered with short, flavescent sub-squamose, not densely set hairs, 

 but having also along the suture, the discoidal part, and the outer 

 margin a distinct but not conspicuous narrow band of ovate scales 

 not set close to each other except on the apical margin where they 

 are denser and deeper yellow ; the propygidium and pygidium are 

 clothed with contiguous golden yellow scales ; the abdomen is also 

 clothed with similar scales which, however, turn to w^hite on the 

 anterior segments ; hind claws single, simple. 



In the male the scales on the elytra are probably more yellow and 

 the bands more distinct. 



Length 5^ mm. ; width 2-J- mm. 



B.ah. Cape Colony (Namaqualand). 



A distinctive character of this species is the deep median groove 

 extending from base to apex on the prothorax ; the only other species 

 in which there is a similar groove is 0. canaUculatus, but the clypeus 

 is not dentate and the anterior tibige are said to be bi-dentate out- 

 wardly.
