Angustum, lineare, testaceo-rufum, longe pilosum, 

 nitidura; capite sparse punctato ; an tennis unicoloribus ; 

 thorace medio raodice convexo, polito, interdum plaga 

 dorsali nigra, vel toto nigro-castaneo polito ; elytris medio 

 vel dimidio basali nigro-castaneo, macula triangular! 

 marginali et paulo post hanc vitta obliqua albis, margine 

 laterali (prope basin excepto) et apice testaceo-albis ; 

 elytris medio depressis.

Common. The space between tha white triangular 

 spot and the oblique fascia of the elytra is not mder than 

 the white belt ; it is sometimes of a darker hue than the 

 rest of the elytra, and looks then like a distinct dark 

 fascia.

2. Gnomidolon rubricolor, n. sp. 



G. Chjmeni valde affinis, differt colore ferrugineo 

 obscuriori et spatio inter fascias elytrorum multo latiori ; 

 ferrugineum, tibiis tarsisque obscurioribus, sparsira hirsu- 

 tura, politum ; elytris apud medium fasciis duabus obli- 

 quis albo-testaceis, prima latiori suturam haud attingente, 

 secunda angustiori integra, apice testaceo-albis. 



Long. 44 lin. c?. 



The two white marks of the elytra constitute two 

 fascia), the first not being triangular. The distance be- 

 tween the two is t^vice the width of the posterior fascia.
