180 Mr. G. J. Arrow on the 



Reiclie, which is often mistaken for it. 0. nasicorm's, E,eiche 

 (of which also we have the type), is a species which I have 

 seen only from Abyssinia, but 0. irdermedius is abundant 

 throughout a large part of Africa and may therefore cross 

 the Mediterranean. Reiche's species, however, were described 

 in 1847, while Costa's descriptions are dated 1849, so that 

 the name of speciosus is a synonym of intermedius, Reiche, 

 Mr. Peringuey, in his ' Catalogue of the Lamellicornia of 

 South Africa,' has incorrectly described this species under 

 the name of 0. nasicornis, Reiche. 



0, pollens, Oliv., ranges from N.W. India across Arabia 

 to Somaliland, and thence through Northern Africa into 

 Corsica. 



0. fulvusj Goeze, has a wide distribution in Europe 

 and extends as far east as Turkestan and as far south as 

 Algeria. 



O.festivus, Steven, is a rare and peculiar species found in 

 Asia Minor and the Caucasus. 



The Oriental Oniticellus vertagus, Fabr., has been many 

 times described. The type of Fabricius's description is a 

 female. Tiie male was first described by Erichson as 0. hi- 

 furcatus and again by Wiiite as 0. bifurcalis. Overlooking 

 all these earlier descriptions, Fairmaire described both sexes 

 in 1891 as 0.f?c^K<.^er?iwm and two years later as 0. ionkineus, 

 taking in the first case a well-developed male and in the 

 second case an imperfectly developed one for his type. 



The following new species of this genus are in the British 

 Museum. 



Oniticellus indicus, sp. n. 



Niger ; antennis, femoribus, prothoracis angulis anticis, elytrorum 



apifiibus, pygidio corporeque subtus plus minusve testaceis ; pro- 



thorace fortiter punctate, late canaliculato ; elytris sulcatis, 



interstitiis modice convexis, minute irregulariter punctatis. 



(S . Capita late carinato, carina medio obtusa, angulis acute dentata ; 



prothorace medio elevate, antice obtuse trituberculato. 

 2 , Capita levirer bicarinato ; prothorace antice obsolete carinato. 

 Long. 7-10'o mm. ; lat. max. 4-6 mm. 



Ilah. S. India, Malabar, Anamalai Hills, Nilgiri Hills 

 (3000-6000 feet). 



Found in dung by Capt. A. K. W. Downing and Mr. H. L. 

 Andrewes. 



Black and moderately shining, with the lower surface, 

 femora, antenna?, front angles of the pronotum, the apices of 

 the elytra, and the pygidium more or less testaceous. The 

 clypeus is punctured and its front margin barely sinuated.
