Mr. C. O. Waterhouse on new Scarabseidse. 367 



This interesting species has the form and general characters 

 of 8. sacer, but has a quite different appearance on account of 

 the silky sculpture and the longer and more dense hair on the 

 legs ; the elytra are a little narrower and the reflexed margin 

 is narrower. The head has a slightly indicated transverse 

 ridge, interrupted in the middle. The teeth in front and 

 those on the anterior tibia? are rather longer and more slender. 

 The thorax has the surface extremely finely coriaceous or 

 granular j studded with very distinct shining granules, the 

 granules rather larger and distinctly more separated from eacli 

 other, and, as is usually the case, they are almost absent in 

 the middle of the base, where there are some distinct, but not 

 very deep, punctures ; small punctures may also be seen 

 near the shining granules. The elytra have the interstices 

 punctured; the punctures are distinct but not deep, irregular, 

 generally separated from each other by about two diameters. 



Sebasteos Poggei. 



Convexus, niger, parum nitidus ; capite crebre ruguloso, epistomio 

 subtus dentibus duobus armato ; tborace lato, convexo, crebre 

 fortiter punctate-, linea mediana laevi, angulis anticis acutis extror- 

 surn directis ; elytris basi angustatis, striatis, interstitiis convexis, 

 punctis nonnnllis subseriatim notatis ; tibiis anticis longis, angus- 

 tis, intus dentatis, ante apicem sinuatis, extus quadri-dentatis. 



Long. 15 millim. 



Hah. Congo. 



Somewhat resembles 8. galenus, but is rather larger and 

 differs as follows : — Head relatively broader, with the poste- 

 rior angles more rounded ; epistome broadly triangularly 

 emarginate, with the two middle teeth not so porrect ; the 

 surface longitudinally rugulose. Thorax very broad, much 

 more strongly punctured, or, rather, the punctures are much 

 larger, irregular, generally very near together ; at the sides 

 small tubercles take the place of the punctures. Elytra con- 

 siderably narrowed at the base, and consequently the sides 

 are more rounded ; the interstices are convex, especially the 

 third and fifth, each with a line of distinct punctures. The 

 anterior tibia? are longer, with the apical third distinctly 

 sinuate on the inner side. 



Gymnopleurus Thelwalli. 



Rotundato-oblongus, bene convexus, fusco-Deneus, supra surdus ; 

 capite antice medio emarginato, granulate ; thorace coriaceo- 

 opaco, nitide granulate, maculis novern paulo elevatis nitidis 

 ornate, lateribus obtuse denticulatis, angulis posticis acutis, paulo 

 productis; elytris brevibus, convexis, granulis minutis aspersis,
