508 Mr. C. 0. Waterhouse on new 



single female examples. As, however, I have exercised 

 great care, I trust I shall not be found to have redescribsd 

 any characterized species among the following. 



Heliocopris Hun ten', sp. n. 



Nigro-piceus ; capite ruguloso, cornubus tribus fero aequalibus 

 erectis instructo ; tborace brevi, sat fortiter reticulato-ruguloso, 

 antice declivi, pone oculos profunde exciso, parte elevata disci in 

 cornu longo horizontali acuminate- producta, cornu ad apicem 

 plus minusve exciso, angulis anticis acntis prominulis laevibus ; 

 elytris nitidis, leviter striatis, striis dorsalibus parce punctulatis, 

 interstitiis planis, parce subtiliter punctulatis, basi quinque-tuber- 

 culatis. 



Long. 17-20 lin. 



Hab. E. Africa, Masai (C. V. Hunter and F. J. Jackson, 

 Esqrs.). 



Allied to //. neptunus, Bohem., but with the armature of 

 the head and thorax quite different. The head is rather 

 large, with three erect acuminate horns, one central and two 

 lateral. A small-developed example has the middle horn 

 shorter and more obtuse, and the lateral ones are only indi- 

 cated by a slight swelling on the margin. The thorax with 

 a single porrect discoidal horn, somewhat as in //. hamifer, 

 Harold, but without the angular enlargement beneath, the 

 apex nearly always notched. The space above the anterior 

 angles is impressed and shining, and the margin behind each 

 eye has a deep, almost circular emargination, leaving the 

 projecting angle of the head behind the eye visible. The 

 anterior angles are very acute and porrect, beset with reddish- 

 brown hair. The elytra have five tubercles at the base, one 

 on each of the second, fourth, and fifth interstices and two on 

 the third ; there is sometimes a trace of one on the sutural 

 interstice. 



Heliocopris operosus, sp. n. 



Piceus 



c? . Capite ruguloso, sat rotundato, medio cornubus duobus 

 erectis acuminatis perparum divergentibus instructo, clypeo autice 

 medio triangulariter paullo emarginato et utrinque leviter 

 sinuato ; thorace brevi, confertim granulato, antice verticali magis 

 rugoso utrinque impresso, impressione laevi, parte elevata trian- 

 gulari utrinque leviter bisinuata, medio obtuse producta, ad api- 

 cem vix emarginata, lateribus pone angulos anticos sinuatis ; 

 elytris nitidis, leviter striatis, striis parce obsolete punctulatis, 

 interstitiis parce sat distincte punctulatis, basi trituberculatis.
