given at plate 3 ak fig. 3. To the family Chiros- 

 celidae I am enabled to add an undescribed genus, 

 lately received from Sierra Leone, besides the genus 

 Prioscelis, which has already been described. I 

 propose the name of Pachylocerus from its remark- 

 ably robust antennae. The following characters 

 detach it from Prioscelis. 



Pachylocerus, Hope. 



Caput magnum, clypeo transverso truncato, an- 

 tennae robustae articulo lmo. crasso, 2do. brevi 3tio. 

 duplo longiori, quinque sequentibus moniliformibus 

 longitudine aequalibus, nono et decimo cyathiformi- 

 bus, extimo ovato. Thorax valde convexus, antice 

 angustior, postice latior, lateribus curvatis. Elytra 

 sulcata, striatopunctata, metallica. Corpus infra 

 nigroaeneum, nitidum, pedibus concoloribus. Femora 

 antica subdentata, sinuata et sulcata, tibiis in sulcis 

 receptis, postica quatuor subrugosa. Tibia cur- 

 vatae, anteriores fortiter unidentatae, mediae subden- 

 tatae, ultimis fere rectis subscabris. 



Habitat in Sierra Leona, 



Pachylocerus, Westermanni Hope. 



Long. lin. 13. lat. lin. 41. Nigroaeneus, thorace 

 glabro, elytrisq. striato-punctatis. Totum corpus 

 supra metallicum, antennis nigro violaceis, ultimo 

 articulo rufescenti, infra nigro aeneum, nitidum. 

 Pedes quatuor anteriore tibiis armatis, tarsis infra 

 piceis, rufescentibus, capillisque obsitis.
