green outer margins, and the antennae and legs reddish, whereas 

 in M. mashunensis, the antennae, with the exception of the basal

GEN. PENTAGONICA, Schm.-Goeb. 

 PENTAGONICA DISPAR, n. sp. 



Head more or less deeply infuscate, prothorax brick-red, antenntc 

 flavescent with the three basal joints fuscous or black ; elytra black 

 with the suture and a narrow lateral margin rufescent ; legs rufes- 

 cent, occasionally partly infuscate ; head very finely and closely 

 aciculate ; prothorax more than twice as broad across the median 

 part as long, very faintly aciculate, and with the median longitudinal 

 impressed line very distinct ; elytra broad, not more than twice 

 longer than the width, deeply striate with the intervals raised, some- 

 what tectiform and very finely aciculate, the striae have faint traces 

 of punctures ; under side either wholly or partly fuscous. 



Length 4 mm. ; width 2 mm. 



Hab. Natal (Durban). C. N. Barker. 



Easily identified by its colouration and the somewhat short and 

 quadrate elytra.

Head, prothorax, and under side brick-red, elytra flavescent with a 

 faint sub-basal fuscous patch on each side, antennae, knees, and tarsi 

 black ; head deeply and closely punctate ; prothorax one-third 

 broader than long, obliquely auipliated laterally in the anterior part, 

 straight or hardly sinuate in the posterior, very rugose, scutellum 

 rugose ; elytra with the humeral part strongly rounded, gradually 

 ampliated laterally towards the posterior part, depressed, striate 

 with the intervals plane and filled with irregularly disposed elongated 

 punctures separated by smooth, raised, also irregular intervals ; the

 the fourth interval, and is situated at a short distance from the base.

Allied to L. holubi, Pering., and differs mainly by the almost con- 

 colorous elytra, the two small infuscate patches being very faint.
