508 Mr. C. O. Waterhouse on new 



single female examples. As, however, I have exercised 

 great care, I trust 1 shall not be found to have redescribed 

 any characterized species among the following. 



Heliocopris Hunteri^ sp. n. 



Nigro-piceus ; capite ruguloso, cornubus tribus fere sequalibus 

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

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

 cornu longo horizontali acuminato producta, cornu ad apicem 

 plus minusve excise, angulis anticis acutis prominulis lasvibus ; 

 elytris nitidis, leviter striatis, striis dorsalibus parce punctulatis, 

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

 culatis. 



Long. 17-20 lin. 



Hob. E. Africa, Masai [C. V. Hunter and F. J. Jackson^ 

 Esqrs.). 



Allied to //. neptunus^ Boliem., but with the armature of 

 the head and thorax quite diflferent. 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 



cJ. Capite ruguloso, sat rotundato, medio cornubus duobus 

 erectis acuminatis perparum divergentibus instructo, clypeo antice 

 medio triangulariter paullo emarginato et utrinque leviter 

 sinuate ; tborace brevi, confertim granulate, antice verticali magis 

 rugose utrinque impresso, impressione Ifcvi, 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.
