yellow and part white ; it was probably yellow when the

Poemenesperus Dohrcei, n. sp. 



Niger, velutinus, griseo variegatus ; antennarum articiilo tertio basi 



apiceque testaceo, articulis sex apicalibus flavis. 

 Long. 8 lin. 



Near P. voluptuosus, Th. (Arch. Ent. i. pi. vi. fig. 6), but 

 with the lateral angle of the thorax much nearer ihe base. 

 Antennae with the base and apex of the third joint and the 

 extreme base of the fourth pale 5 half the fiftli and all the sixth 

 to tenth joints yellow ; the eleventh is yellow, except at the 

 extreme apex. Head black ; the face, a central line, a patch 

 behind, and a dot above each eye pale grey. Thorax black, 

 witli a line along the anterior margin, another at the base, an 

 irregular line over the lateral spine, and a A-shaped mark on 

 the disk grey. Elytra at the base a trifle broader than the 

 thorax, with obtuse but prominent shoulders, black, with a 

 transverse grey band at the base ,• this descends a little at the 

 suture, dentate along its basal line ; at the middle there is a 

 grey line which, commencing on the margin, extends to the 

 middle of the elytron, where it ascends a little, and then turns 

 at right angles towards the suture, where it again descends 

 for some distance and is united to another band, which leads 

 back to the original point on the margin. At some distance 

 from the apex there is an oblique grey band which nearly 

 reaches the suture and then descends to the apex, emitting a 

 small branch about halfway to the apex ; there is also a grey 

 spot on the margin close to the apex. The underside and legs 

 are grey, dotted with black.

I have only seen one specimen of this elegant species. I 

 have named it after its captor, the late Robert B. Dobree, Esq. 



Dynastidae. 

 Brachysiderus, n. gen.

 male evenly convex and without tubercle or horn. Ocular 

 canthus with its anterior angle directed forward into a short 

 sharp tooth. Horn on the clypeus a little longer than the 

 head, thick, horizontal, dilated at the apex, which is emargi- 

 nate, the angles acute and turned slightly upwards. Legs 

 much more robust and more flattened than in Antedon,
