by a short labrum, or a bidentate lab rum, or by reduction 
of width of head in relation to prothorax, characters that 
are not even suggested in the new New Guinea species. 
The latter is therefore not only the first Prothyma of any 
sort found in New Guinea, but it extends the known range 
of Prothyma s. s. into the Australian Region. It appears 
to be a very distinct species. It differs from most Orien- 
tal Prothyma ( e.g from quadripunctata F. and hetero- 
malla Macl. of Java) in elytra! color pattern, which in 
most Oriental species consists of white spots on a dark or 
metallic background, but which in papua consists of an 
incomplete pale submarginal and apical vitta partly in- 
terrupted by incursions of the narrow marginal metallic 
color. The elytra are wider near the apex in papua than 
in any other Prothyma of which I have seen specimens 
or figures.
