declivity of the elytra, which are also distinctly convex in the 

 posterior part of the disk above the declivity, whereas in M. lati- 

 pennis they are sloping and plane ; and as it proves not to be M. 

 scabra, Klug., I propose for it the name of M. manicana. 



As for M. living stoni, Casteln. =M. mygaloides, var. damarensis, 

 Per., Dr. Horn has come to that conclusion from seeing the original 

 example of Castelnau now in the Oberthur collection. I have also 

 seen these Mantichorce, which came mostly from the Mniszech 

 collection, but I could not make any use of them at the time, 

 as there certainly was no proof of their having ever been in the 

 possession of de Castelnau, or of their being the originals or types 

 from which the descriptions were made.

Dr. Horn has kindly sent the description of a new South African 

 species to be included in the present Supplement. 



Megacephala peringueyi, W. Horn.

pi. iv., fig. 3. 



Allied to M, regalis, Boh., but the five teeth of the labrum are a little 

 larger, the frontal impressions are deeper ; the prothorax is broader 

 and much depressed, the sides are less rounded, the posterior angles 

 much more prominent ; the elytra are narrower, longer, very much 

 less convex, and very much more declivous towards the apex, the 

 tubercles, which are of the same size, are somewhat less thickly set, 

 especially alongside the suture in the anterior part, where they are 

 much less distinct ; in fact they leave there sometimes a narrow 

 longitudinal sub-sutural denuded space (compare the figure given 

 by Thomson, loc. cit., pi. iv., fig. 3) ; the suture is not plane but 

 narrowly, yet distinctly, raised ; the last joint of the maxillary and 

 labial palpi is much less dilated, and the posterior tarsi are hardly 

 longer. The whole body above and beneath is a dark emerald green, 

 the posterior part of the sternum, and also the abdomen are piceous, 

 and the apical part of the latter is hardly infuscate ; labrum, antennae, 

 palpi, coxae, trochanters, and legs testaceous, but now and then a 

 little darker. Length (males), 25-26 mm. 



Nearly similar in shape to M. bennigseni, Horn.
