I cannot place the insect for which I propose this name in any 

 previously characterised genus. Its facies is somewhat like that 

 of Galhodema but its structural characters are different. Its non- 

 sulcate metasternum and abdomen, non-lamellated tarsi, hind- 

 coxal lamellae strongly narrowed towards the lateral margin of 

 the body, antennae received in deep sulci between the propleural 

 triangle and the margin of the pronotuni (which sulci become 

 much narrowed on the head and are distinctly separated from 

 the propleural triangle by a continuous raised line), 4'^ tarsal 

 joint not simple, and elongate filiform antenna?, place it (in M. de 

 Bonvouloir's tabulation, loc. cit.) in the group of nine genera 

 beginning with "No. 36 " and ending with "No. 41." Among 

 those genera the present one may be easily recognised by the 

 following characters in combination: — prosternal sulci much more 

 than half as wide as the base of the propleural triangle, antennae 

 quite simple 3'''^ antennal joint very distinctly longer than 4*'', 

 elytral epipleurse becoming very narrow before the middle, apex 

 of clypeus very strongly sinuous, and (especially) the unusual 

 structure of the lateral edging of the pronotum which (in nearly 

 its whole length) consists of two fine elevated lines with a very 

 narrow convexity between them and which consequently is sinular 

 to the epipleurai of the elytra about their middle. I think this 

 genus may stand next to Galbodema from which its simple 

 antenna?, narrower prosternal sulci, and bicarinate edging of 

 pronotum furnish inter alia abundant distinctive characters.
