A widely-distributed genus including upwards of twenty described species, all of 
very small size and some of them variable in colour. Six are known to me from within 
our limits, two of which are treated as new, though they are represented in each case 
by single examples. The males appear to have the second antennal joint more or less 
thickened in many of the species. Our six representatives may be separated thus :— 
a. Posterior lobe of the pronotum rugose or rugulose. 
a’, Elytral pubescence golden ; membrane fuscous: length 23 millim. . fuscus, Reut. 
b’. Elytral pubescence not metallic; membrane subhyaline : length 13-2
