Somewhat close to R. Mussoni, Blackb., but eaaily dis- 

 tinguishable by the much longer joint 3 of its antennae, the 

 manifestly sparser and feebler puncturation of its pronotum, 

 and the evident angularity of the latero-median dilatation of 

 its prothorax.

 R. rugulosa, sp. nov. Sat lata; supra subglabra, sternis 

 pedibusque longe fulvo-pilosis ; rufo-brunnea ; capite 

 pronotoque sat fortiter vix crebre vix rugulose punctu- 

 latis ; clypeo minus transverso peralte reflexo ; palporum 

 maxillarium articulo apicali supra concavo, parte con- 

 cava coriacea; an tennis 10-articulatis ; prothorace quam 

 longiori ut 5 ad 3 latiori, antice sat angustato, lateribus 

 crenulatis sat fortiter nee angulatim rotundatis, angulis 

 posticis rectis, basi bisinuata; elytris longitudinaliter 

 obtuse sat obsolete costulatis, rugulose subgrosse vix 

 crebre punctulatis ; pygidio coriaceo, leviter minus con- 

 fertim subtilius punctulato. 

 Maris antennarum articulo 3° quam latiori multo longiori 

 sat cylindrico, flabello quam articuli ceteri conjuncti sat 

 longiori 6-articulato (illius articulo primo quam ceteri 

 tribus partibus breviori). 

 Feminae antennarum flabello quam articuli ceteri con- 

 juncti multo breviori, 6-articulato (illius articulis primo 

 perbrevi, 2° 3° 4° gradatim longioribus, 5° 6° que 4° 

 - agqualibus) ; tarsis quam maris multo brevioribus.

Nearest to It. du hi tans, but at once distinguishable from 

 it by the evidently closer puncturation of its pronotum, the 

 punctures of its pygidium much less close and much larger, 

 and the sides of its prothorax evenly (without any angularity) 

 rounded in the middle. There is no pilosity on the dorsal 

 surface of either of the specimens before me, and this does not 

 appear to be the result of abrasion.

 R. consan guinea, sp. nov., Mas. Praecedenti (R. rucftolosw) 

 affinis ; multo magis angusta ; antennarum articulo 3° 

 breviori, quam latiori haud multo longiori, ad apioem 

 quam ad basin multo latiori, ante apicem intus manifeste 

 anguliformi ; antennarum flabelli articulo 1° paullo 

 longiori ; prothorace antice magis angustata, ad basin 

 manifeste lobato; elytrorum costulis multo minus obso- 

 letis.
