Hab. New Guinea, Fly River (L. M. D'Albertis). 
This species seems closely allied to O. béfasciata Blanch. but 
differs in the colour of the antennae and that of the tibiae 
which is the same in the 14 specimens before me; the narrow 
fulvous space dividing the two black bands of the elytra is 
always much narrower than the anterior black vitta, but the 
distance of the latter from the base is somewhat variable. 
8. Oides biplagiata, Jacopy. 
Of this species which was described by myself in the Pro- 
ceed. Zool. Soc. 1883, there are specimens obtained at the 
Fly River, in which the two elytral black spots are united 
and occupy the entire last two thirds of each elytron; as also 
intermediate forms are before me in which one can see an 
indication of the spots to separate as in the type, the identity 
of these varieties with the latter is clear. 
9, Oides decemguttata, n. sp. 
Testaceous; head and thorax impunctate; elytra strongly and 
closely punctured, each elytron with 5 black spots, 2. 1. 2, 
posterior part of the suture narrowly piceous. 
Length 4-4 1/, lines. 
Head entirely impunctate, testaceous; the third joint of the 
antennae, shorter than the fourth, this the longest; thorax of 
the same shape as in O. nigroplagiata, impunctate or in some 
specimens extremely finely punctured; elytra very distinctly and 
closely punctured, with the following black spots, an elongate 
one at the shoulder and a shorter one near the scutellum, a 
round spot at the middle and close to the suture and two elon- 
gate spots nearly joined at their ends, near the apex of each 
elytron, the outer one of these is placed close and parallel to 
the lateral margin, the inner one is straight and in a line with 
the central spot; the suture is also very narrowly margined 
with black, the posterior portion being widened into an elongate
