Ti. litigiosus, sp. nov. Sat elongatus, postice parum dilata- 

 tus; sat nitidus; brunneus, antennis palpisque testaceis; 

 pilis cinereis brevibus minus dense vestitus; clpeo con- 

 fluenter ruguloso, antice (minus leviter) emarginato; 

 labro summo clypei planum nullo modo attingenti ; fronte 

 sat grosse nee crebre punctulata, fronte clypeoque 

 planum sat aequalem efficientibus ; antennis 8-articulatis ; 

 prothorace quam longiori ut 11 ad 6 latiori, antice modice 

 angustato, supra fortiter nee crebre punetulato (punc- 

 turis eirciter 14 in segmenti longitudine), lateribus levi- 

 ter areuatis, angulis antieis acutis minus productis 

 postieis (superne visis) acutis retrorsum directis, basi 

 fortiter bisinuata, margine basali sequaliter elevato ; 

 elytris coneinne sat fortiter punctulatis (trans elytron 

 puneturis eirciter 25) ; pygidio sparsim sat grosse nee 

 profunde punetulato : coxis postieis quam metasternum 

 sat brevioribus, quam segmentum ventrale 2""^ sat 

 longioribus; tibiis antieis extus fortiter tridentatis; 

 tarsorum postieorum articulo basali quam 2"s multo 

 breviori (3° sat asquali) ; unguiculis leviter bifidis. 

 Long., 5 1. : lat., 2J 1. 



Near R, fulvohirtus^ Blaekb., but distinguishable as in- 

 dicated in the tabulation. It also differs by its more strongly 

 emarginate elypeus, its frons much less closely punetulate, 

 its elytra less coarsely and less sparsely punetulate. The 

 claws of this species are not strongly removed from the 

 appendiculate type, but the basal piece is too strongly denti- 

 form at its inner apex to allow of the claws being called 

 appendiculate. If they were regarded as appendiculate the 

 quite strongly subangularly emarginate elypeus would 

 readily distinguish this species from those near which it 

 would fall in the tabulation of Group II.
