produced, the surface finely and closely punctured ; scutellum pale fulvous, longer than 

 broad ; elytra scarcely broader at the base than the thorax, slightly widened towards 

 the middle, convex, the surface punctured like the thorax, the anterior and po.-terior 

 third poition, reddish fulvous, the middle occupied by a broad black band extending 

 across the elytra to either margin, the edges of this band rather irregular ; underside 

 flavous, the breast sometimes and the legs black. 



Hnh. Humlx)ldt Bay (New (fuiuea). 



Distinct from any of its allies in the pattern of the elytra, also in the pro- 

 duced nietasternum, which nearly resembles the genus Cerochroa although less 

 pronounced. 



Oides suturalis .-p. nov. 



Black, head impunctate, thorax fla\ous, finely pimctured, elytra very closely and 

 finely i)unctnred, flavous, the sutural and lateral margins very narrowly and rather 

 obscurely piceous, metastemum strongly [jroduced. 



Length 4 lines. 



Elongate, scarcely widened iK)steriorly, con\ex, the head black, impunctate, 

 frontal tubercles transverse, joined in front, clypeus triangular, antennae extending 

 beyond the middle of the elytra, black, the fourth joint double the length of the 

 third, following joints e(iual ; thorax three times broader than long, the sides slightly 

 rounded near the base, but little narrowed towards the apex, anterior angles not 

 produced, but distinct, surface strongly, but remotely i>unctured ; scutellum broad, 

 black, its ajjex rounded; elytra darker than the thorax or of the same colour, very 

 finelv and closely punctured, the extreme mai'gins very narrowly jjiceous, under- 

 side and legs black ; last abdominal segment of the ma/e with a medial lobe, the 

 surface of which is concave; metastemum strongly raised, truncate in front. 



Hah. Humlx)ldt Bay (New Guinea). 



This species agi"ees in the shape of the metastemum with the preceding one, 

 and ought jierhaps to be placed in another genus, although the other structural 

 characters agi'ee with Oides. 



Oides clypeata -p. uo\. 



Black, the clypeus, antennae, thorax, legs and sides of the brea>t flavous, thorax 

 minutelv jmnctured, elytra bluish or black, finely and closely punctured. 



Length 4 to o lines. 



Head black at the vertex, impunctate, the frontal elevations, clypeus and labrum 

 flavous, antennae extending beyond the middle of the elytra in the male, dark 

 fulvous or flavous, the fourth joint one half longer than the third, the fifth equal to 

 the thii'd joint ; thorax narrowly transverse, jparallel, the sides and the angles .slightlv 

 rounded, anterior and posterior margin nearly straight, the surface with a few minute 

 punctures and an obsolete depression at the sides; scutellum triangular, flavous; 

 elvtra widened at the middle, very evenly, closely and finely punctured, with a deep 

 depression below the shoulder and a broadly flattened margin ; underside black, the 

 sides of the breast and the legs flavous, the last abdominal segment of the 7naU 

 flavous at the apex, the latter conca\e-emarginate. 



Hah. Humboldt Bay (New Guinea). 



1y;o feraale specimens which I received from Dr. Staudinger, and also obtained 

 in New Guinea, are larger, have blackish elytra and fla\ous antennae, but differ in 

 no other wav.
