NEW PHYTOPHAGOUS COLEOPTERA 49 
fulvous with an apical triangular black patch; as I cannot see 
any structural differences I have no doubt about all these forms 
representing but the same species. 7 
14. Oides ornatum, Baty. 
Hab. New Guinea, Andai, August, Mt. Epa, April (L. M. D’Al- 
bertis). Has, February, Dorei (O. Beccari). 
A number of specimens from the above localities agree very 
nearly, although not quite, with the description of the author, 
others want the posterior black elytral spot; in some the an- 
tennae are obscure fulvous as well as the entire underside and 
legs. The species seems to be a very variable one in colouration 
and may possibly only be a variety of O. rubrum Blanch. As 
the specimens obtained in the same localities seem to vary 
equally, not much reliance can be placed on the markings and 
colour in separating the species. O. basale Guér., seems to me 
also to be only a variety of O. rubrum in which the subapical 
blacks pots of the elytra are wanting. O. 4-notatwm Blanch. seems 
again either a closely allied or identical species with either of 
the above named. 
15. Aulacophora dilatata, n. sp. 
Dark fulvous, dilated behind; sides of the thorax rounded, 
the surface impunctate; elytra extremely finely punctured , 
strongly widened behind; antennae testaceous. 
Q. The apical joint of the antennae widened, its margin pro- 
duced and pointed. 
Length 4 lines. 
Hab. Borneo, Sarawak (Doria and Beccari). 
This species is closely allied to A. wnicolor Jac., from the 
Island of Saleyer, but is smaller, of a darker colour and differs 
in the shape of the thorax, the sides of which are evenly roun- 
ded, not straight at the base as in A. wnicolor; the antennae 
are also of different construction, the joints being much shorter
