 subtilissime punctulatis. Corpus infra nigrum quarto annulo ab- 

 dominis postice flavo-marginato. Femora tibiis atris et pilosis, 

 tarsisque infra piceo-comatis. 



This is the third species only which has yet been described I be- 

 lieve as really African ; it cannot be confounded with the Baron De 

 Jean's africana or Schonherr's interstitialis .

 anea, duobus primis articulis antennarum rubris reliquis atro-piceis. 

 Caput atrum et punctatum. Thorax elongato-ovalis, antice et 

 postice abrupte truncatus. Ely tra viridia striato-punctata. Corpus 

 infra pectore rufo, quatuor ultimis segmentis abdominis nigris.

 tennis marginibusque thoracis brunneis, elytris atris, binisque flavis

 tarsisque infra auri-comatis. 

 Hab. In Sierra Leona. 

 This insect was given to me by Lieut. Sayers with other insects 



collected in that colony. 



Sp. 20. Orthogonius longipennis, Hope. Long. lin. 8 ; lat. lin. 3|. 

 Prsecedenti aflinis, at minor. Nigra, antennis obscure atris, thorace 

 concolori, disco crebris rugis insignito, marginibus depressis. Elytra 

 thorace fere quadruplo longiora, sulcata, sulcis haud fortiter punc- 

 tatis. Corpus infra atrum tarsisque infra nigro-piceis.

A peculiarity of this insect is worthy of notice : the second elevated 

 ridge on each side of the suture, nearly about the middle of the elytra, 

 is abruptly traversed by a transverse ridge, thereby dividing the stria 

 in two parts ; all the rest are entire. It is probably only a sport of 

 nature.

 antennis articulo primo rubro, reliquis fusco-piceis et pilosis. Tho- 

 rax convexus, in medio ater, marginibus externis depressis et brun-
