some examples almost dentate, in the base of the prothorax there are 

 some squamose yellow appressed hairs forming a narrow marginal 

 line, which is often obliterated ; scutellum with yellow squamose 

 hairs ; elytra not costulate but impressed longitudinally along the 

 suture and on the disk, roughly punctate and clothed with fine, 

 somewhat dense, slightly flavescent appressed hairs ; pygidial part 

 and abdomen covered with contiguous round yellow scales ; anterior 

 tibiffi sharply bi-dentate, not angular, but pluri-serrate above the basal 

 tooth ; hind claw double. 



Female : Like the male, but the angles of the clypeus are not so 

 sharp, the pubescence on the elytra is not quite so dense, and the 

 pygidial part is covered with appressed yellow hairs. 



Length 4 mm. ; width 2 mm. 



Hab. Cape Colony (Cape Town, Stellenbosch). 



This species is not a Platyclielus, although described as such by 

 Blanchard, whose type (a female) I have examined ; it much re- 

 sembles 0. depressus, spatulipcnnis, &c., but is at once distinguished 

 by the bi-dentate fore tibiae. 



Omocrates canaliculatus, Blanch., 

 Catal. Coll. Entom. Mus. Par., p. 66. 



Male: "Black, nearly glabrous, antennae, palpi, legs, and abdomen 

 rufous ; head rugose, clypeus quadrate with the angles slightly 

 prominent ; prothorax convex, punctate, shining, sides setose, median 

 part very broadly furrowed ; scutellum fuscous ; elytra short, punc- 

 tate, testaceous, somewhat rufescent at the base and at the apex ; 

 pygidium clothed with flavous scales ; anterior tibiae bi-dentate 

 outwardly. 



Length 4 mm. 



Hab. Cape of Good Hope." 



The only example that I have seen is Blanchard's type. It is very 

 closely allied to 0. spatulipcnnis, but it is glabrous on the upper side, 

 and the prothorax has a very broad median sulcus. 



Omocr.\tes elongatus, Blanch., 

 Catal. Coll. Entom. Mus. Par., p. 66. 



Male: " Narrow, black, pilose, the hairs ashy-grey, antennae and 

 palpi fuscous ; clypeus concave with the angles px-ojecting ; prothorax 

 convex, closely punctate, clothed with greyish hairs ; scutellum 

 squamose ; elytra testaceous red, elongate, sparsely pilose ; legs 

 black, tarsi of the hind legs red at apex ; anterior tibiae bi-dentate,
