to the apex ; the underside black, the legs and the basal portion of 

 the posterior femora flavous ; posterior tibias strongly widened 

 and deeply channelled, their metatarsus as long as the following 

 joinf-s together. 



Hah. Durban, Natal ((?. Marshall). 



Apktho]s^a bohemani, sp. n. 



Below piceous, the head, basal joints of the antennae, the thorax, 

 and the anterior legs reddish fulvous ; elytra metallic dai'k blue, 

 finely and closely punctured. 



Length 3 millim. 



Of subquadrate-ovate shape ; the head ira punctate, reddish 

 fulvous, the frontal elevations not developed, clypeus strongly 

 raised between the antennte, labrum piceous ; the antennae slender, 

 black, the lower four joints flavous, the second and third joints 

 equal in length, the following scarcely longer ; thorax subquadrate, 

 one-half broader than long, the sides nearly straight, the anterior 

 angles oblique, the surface entirely impuuctate, reddish fulvous, 

 shining ; scutellum black ; elytra wider at the base than the thorax, 

 convex, the shoulders moderately prominent, the disc finely and 

 closely punctured, metallic dark blue, the interstices finely wrinkled 

 here and there ; below and the posterior femora nearly black, the 

 legs fulvous, the tarsi more or less fuscous, the posterior tibiae more 

 broadly sulcate, their metatarsus as long as the following joints 

 together. 



Hah. Erere, Natal, under bark of Eucalyptus globulus (G. 

 Marshall). 



A species distinguished by the metallic dark blue elytra and 

 the fulvous head and thorax. 



Okneates, gen. n. 



Body ovate ; antennae with the third and following joints 

 triangularly dilated ; thorax transverse, with rounded posterior 

 angles, the surface without sulcus ; elytra irregularly punctured ; 

 posterior femora strongly thickened, the tibiae longitudinally 

 channelled, all armed with a small spine, the first joint of the 

 posterior tarsi as long as the following two joints together, claws 

 feebly appendiculate ; the anterior coxal cavities open ; presternum 

 extremely small. 



This genus seems allied to Trymnes "Weise (Jamesonia Jac.) on 

 account of the rounded posterior angles of the thorax and the very 

 narrow prosteruum ; but the entirely different structure of the 

 antennae, which differ in their dilated joints from most other 

 genera of Halticince, Aviil at once distinguish it. 



Oen^eates nigritus, sp. u. 



Entirely black, shining, head nearly impunctate, thorax distinctly 

 and rather closely punctured; elytra similarly but more closely 

 puncturpd, the interstices finely wrinkled. 



Length 2 lines.
