acute trigone ; elytris thorace haud latioribus humeris callosis, 

 lateribus ante medium coarctatis, apice nonnihil rotundatis, serru- 

 latis, supra deplanatis, ad humeros utrinque profunde impressis, 

 crebre punctulatis, humeris apiceque fulvo-fasciculatis, plagis juxta 

 suturalibus tribus umbrino velutinis pube albida marginali fascicu- 

 loque laterali atro post medium sito utrinque ornatis. 



Long. 11 mm.; lat. Ah mm. 



Hah. Natal (Stanger). 



Not unlike in general facies small examples of P. exasperans, but 

 the shape of the head and prothorax is very different, as both are 

 devoid of tubercles ; in well-preserved examples it is probable that 

 the wide depression on each side of the discoidal part of the 

 prothorax is clothed with denser fulvous hairs ; the vestiture of 

 the elytra is very faint ; and along the coarctate part there is on 

 each side a nearly obliterated patch of short, blackish -brown hairs. 



KEEEEMANSIA, n. gen. 

 Caput breve, fronte longitudinaliter canaliculata, epistome breve, 

 antennarum sulcis brevibus, genis carinulatis ; oculi longi, paralleli ; 

 prothorax basi utrinque sinuatus, supra convexiusculus, in medio 

 adque ad latera utrinque profunde sulcatus ; scutellum valde 

 elongatum, acutissimum, latitudine maxima fere duplo longius ; 

 elytra deplanata parte postica in arcum recurva, callo humerali 

 apicalique bene notata, abdominis partem dorsalem lateraliter haud 

 tegentia ; presternum latum, apice aculeatum, mesosternum etiam 

 latum, pro receptione processus prosternalis antice excavatum, in 

 medio sat profunde longitudinaliter canaliculatum ; metasternum 

 angustum ; pedes validi, femoribus tibiisque intus conspicue arcuatis, 

 tibiis sub-falciformibus atque valde compressis, fere laminatis, intus 

 dense sub-rigide ciliatis, pedes paris tertiae anterioribus intermediis- 

 que nonnihil graciliores ; abdomen convexum, segmentis basalibus 

 binis a sutura in medio haud divisis ; pygidium in medio spino- 

 sulum. 



The species of Buprestidae, for which I propose the creation of this 

 genus, are found holding by means of their arcuate legs to the edge 

 of the leaves of plants which they thus devour laterally. Kerremans 

 considers that the genus should come next to Alcinoils or 

 Synckocera, Deyr., of the group Agrilida. I think that it is also 

 closely allied to Toxoscelus, Deyr. 



The main characteristic is the shape of the anterior and inter- 

 mediate legs.
