NEW PHYTOPHAGOUS COLEOPTERA 79 
elytra slightly widened behind, the entire surface wrinkled and 
the interstices closely punctured; pygidium black’ above. 
Hab. New Guinea, Fly River, Katau (L. M. D’Albertis). Ramoi 
(Beccari). 
Separated from P. distincta Baly and the other allied species 
by the white base of the joints of the antennae and by the 
rugose not smooth disc of the thorax. 
54. Prasyptera dubiosa, n. sp. 
Black; lower part of the face, thorax, femora and the base 
of the abdominal segments fulvous; thorax twice as broad as 
long, finely punctured; elytra metallic green extremely closely 
punctured and finely rugose. 
Length 4 1/, lines. 
Head impunctate at the vertex, the latter piceous; frontal 
tubercles acutely raised, trigonate, divided by a central groove; 
clypeus testaceous, nearly impunctate; labrum black ; palpi slen- 
der, black; antennae black, the third joint scarcely double the 
length of the second, the apical joint wanting; thorax not more 
than twice as broad as long, the posterior angles obliquely 
rounded, surface obsoletely depressed at each side, extremely 
finely punctured; scutellum black; elytra bright green, very 
closely and finely punctured and wrinkled; pygidium black. 
Hab. New Guinea, Wa Samson (O. Beccari). 
P. dubiosa differs from all other species of the present genus 
by the much less transverse thorax and the more slender palpi; 
the other structural characters are however all present; the 
elytra are more finely and closely rugose and punctured than 
in the allied species and the entire breast as well as the abdo- 
minal segments, with the exception of the base of the latter 
are black; a single specimen only, a female, is before me. 
The 2 following species, of which I have only a single spe- 
cimen for comparison seem again to differ from any of those 
described by M." Baly.
