Jfomia tuberculifrons Cockerell. 
Both sexes from Singapore {Baker). The male is new; it 
differs by being less robust; the scape entirely red in front; 
third and fourth antennal joints conspicuously red; lower half 
of clypeus ferruginous, shining, with very few punctures, upper 
half keeled, labrum and mandibles red; hind legs slender and 
simple, except that the tibiae are broadened a'pically, and the 
apical portion is bent or twisted out of a line with the rest. 
The abdomen has five pale green bands, slightly tinged with 
red. The nervures are pale fuscous, not black as described for 
N. erythropoda, but in general the description of erythropoda 
agrees well, and it is possible that tuberculifrons is erythropoda, 
or a race of it.
