Lebia vaciva. 



Head black, aciculate, briefly pubescent ; antennae deeply infuscate 

 with the exception of the three basal joints which are flavescent ; 

 prothorax deeply aciculate and pubescent, sinuate laterally behind, 

 light brick-red ; elytra sub-parallel, moderately shining, distinctly 

 pubescent, narrowly punctato-striate with the intervals plane and 

 aciculate ; they are pale yellow, with a sutural, elongato-quadrate 

 black patch extending to the fourth stria on each side and reaching 

 to about one-third of the length, and hamate on the posterior edge ; 

 this basal patch is connected by means of a narrow black band 

 running along the first and second intervals with a post-median 

 black band, strongly bi-sinuate on both edges, and reaching the outer 

 margin on each side ; the apical part is narrowly infuscate and 

 coalesces laterally with the outer edge of the post-median patch, so 

 as to enclose an irregular sub-quadrate patch of the yellowish back- 

 ground ; legs flavescent ; fourth joint of tarsi dilated and lobate. 

 Length 5 mnu ; width 2J mm. 



Allied also to L. eximia, CataL, p. 259 ; it is a little shorter and a 

 little less elongate ; equally pubescent, and the disposition of the 

 black patches on the elytra is of the same pattern ; they are not, 

 however, so broad in L. vaciva, in which the apical part is infuscate ; 

 the head is distinctly black and the antennas very deeply infuscate, 

 whereas in L. eximia they are brick-red. 



Hab. Zambesia (Salisbury). 



Lebia natalis. 



Head and elytra black, shining; prothorax, the three basal joints 

 of antennae, and the legs red ; tarsi black or infuscate, palpi black, 

 rufescent at tip ; head and neck finely yet distinctly aciculate ; pro- 

 thorax faintly plicate, very little sinuate laterally above the posterior 

 angle ; elytra nearly one-third broader at base than the prothorax, 

 a little ampliated gradually from below the shoulder to a short 

 distance from the apex where they are about one-fifth broader than 

 at the base, striate, with the striae punctulate, and the intervals 

 convex and almost carinate laterally ; fourth joint of the tarsi sub- 

 lobate ; metasternum and abdomen black. Length 5 f-8 mm. ; 

 width 3-4 mm. 



Allied to L. speciosa, CataL, p. 264; differs mainly in the shape 

 of the intervals of the elytra which are convex, and almost carinate 

 laterally instead of being quite plane in L. speciosa, in which also
