PsEUBITOIfGlUS, D. geU. 



Body ovate, non -pubescent ; antennae filiform, the apical joints 

 thickened ; eyes notched ; epistome not separated from the face ; 

 thorax transversely subcylindrical ; elytra punctate-striate ; femora 

 fusiform, unarmed, the posterior four tibiee emarginate at the apex, 

 nou-sulcate ; claws bifid, the inner division very short ; prosternum 

 broad, one-half longer than broad; the anterior margin of the 

 thoracic episternum strongly convex. 



I am obliged to separate this genus from all others belonging 

 to the group of T>/j>02yhorince on account of the want of an ocular 

 sulcus, the non-separation of the clypeus from the face, and the 

 unarmed femora ; the shape of the thorax agrees partly with 

 Syagrus, but there is no trace of any tooth at the femora ; in the 

 general ovate and posteriorly pointed shape the species difiiers 

 also from most of its African congeners of this group. 



PSEUDITONGIDS JfATALENSIS, n. Sp. 



Oblong-ovate, dark aeneous, the basal joints of the antennae and 

 the tarsi and tibiae fulvous ; thorax finely and closely puuctui'ed, 

 elytra strongly punctate-striate, the shoulders ■^^■ith two short 

 oblique costae. 



Length |-1 Hne. 



Head finely and somewhat rugosely punctured, the clypeus not 

 separated from the face, its anterior margin concave, eyes distinctly 

 notched, labrum piceous ; antennas filiform, tlie apical five joints 

 thickened, black, the lower four joints fulvous ; thorax transverse, 

 subcylindrical, the sides strongly deflexed, the lateral margin 

 nearly straight, the sui'face finely and rather closely punctured, the 

 space near the lateral margins nearly impunctate ; scutellum tri- 

 angular, impunctate ; elytra widened at the middle, pointed pos- 

 teriorly, dark teneous, strongly punctate-striate, the interstices 

 slightly convex and impunctate, those at the shoulders forming two 

 short oblique, more or less distinct costae, the punctures at the 

 same place abbreviated or joined at the ends ; the suture in the 

 female deeply depressed at the posterior portion, forming a longi- 

 tudinal sulcatiou ; underside nearly black, with greenish gloss at the 

 breast ; legs fulvous, the femora metallic greenish at the middle 

 portion ; prosternum strongly rugose. 



Hab. Natal, Estcourt {G. Marshall). 



This small species will not be difficult to recognize on account of 

 the ovate shape, the short elytral humeral costae, and the peculiar 

 sutural depression in the female, of which I know no similar instance 

 amongst the numerous other African genera of Eumolpidae. 



PsETJDOMAXEGiA, n. gen. 



Body oblong, pubescent ahove and below ; eyes entire ; antennae 

 filiform, the last five joints thickened ; thorax subcylindrical, 

 rather flattened, without distinct lateral margin ; femora un- 

 armed ; tibiae not emarginate at apex; claws bifid; prosternum
