apex, the second, half the length of the third, the others nearly 

 equal in length ; thorax transverse, subquadrate, twice as broad as 

 long, the sides very slightly rounded before the middle, the anterior 

 angles oblique, not produced, posterior ones distinct, the surface 

 ■with a narrow transverse sulcus, not quite extending to the lateral 

 margins, the disc punctured like the head, fulvous, shining ; scu- 

 tellum fulvous ; elytra dark blue, the extreme sutural margin and 

 the epipleurie fulvous, the disc strongly and closely longitudinally 

 eostate, each elytron with eight costae and another short subsutural 

 one, the interstices transversely rugose-punctate : underside and 

 the legs fulvous, posterior femora moderately incrassate, the first 

 joint of the posterior tarsi as long as the following joints together ; 

 prosternum narrow and strongly raised, the anterior coxal cavities 

 closed. 



Hah. Zambi, Congo (coll. Belgian Mus. and my own). 



This iusect differs from typical species of Crepidodera in the 

 very narrow and strongly convex jirosternum, also in the absence 

 of a lateral perpendicular groove, which generally limits the trans- 

 verse sulcation of the thorax ; it should perhaps be placed in a 

 separate genus. 



Ceepidodeha natalbnsis, sp. n. 



Piceous, the antennae and legs flavous, above obscure eeneous ; 

 thorax very finely and closely punctured, with deep basal sulcus 

 and lateral grooves ; elytra finely punctate -striate, the interstices 

 sparingly and minutely punctured. 



Length 3 raillim. 



Head greenish aeneous, entirely impunctate, with a short perpen- 

 dicular groove immediately above the eyes, frontal elevations small ; 

 the clvpeus with an acutely raised central ridge ; the antennae 

 slender, flavous, the terminal joint stained with fuscous, the 

 second joint scarcely shorter than the third, the terminal four joints 

 slightly thickened ; thorax about one-half broader than long, the 

 sides straight at the base, rounded before the middle, the angles 

 distinct but not acute, the surface very closely and finely punc- 

 tured, greenish aeneous, the basal sulcus very deep and bounded 

 laterally by an equally deep longitudinal groove, which extends 

 upwards some little distance, the basal portion behind the sulcus 

 of more distinctly fulvous colour and likewise finely punctured ; 

 elytra elongate and convex, the apex rather pointed, the basal portion 

 very feebly depressed, the disc rather strongly and very regularly 

 puiictate-striate, of the same colour as the thorax, the interstices 

 very finely punctured ; below and the legs flavous, the apex of the 

 posterior femora more or less stained with piceous. 



Hal). Estcourt, Natal ((?. Marshall) ; also Dunbrody, S. Africa 

 {Rev. T. O'Neil). 



This little species must be closely allied to C. tosta Gerst. in 

 regard to its obscure aeneous coloration, but the impunctate head, 

 very closely punctured thorax, and its distinct transverse basal 

 sulcus prevent the insect being identified \nth the last-named
