NEW PHYTOPHAGOUS COLEOPTERA 47 
piceous stripe; the underside and legs are flavous or testa- 
| Ceous. 
Var. The terminal joints of the antennae more or less fuscous. 
Hab. New Guinea, Fly River (L. M. D'Albertis). 
10. Oides nigroplagiata, n. sp. 
Head, antennae, tibiae and the abdomen black, thorax and 
elytra fulvous, closely punctured, the latter with the posterior 
two thirds, abbreviated at the suture, black. 
Length 4 lines. 
Head with a few very fine ha , visible only under a 
lens; the anterior margin of the clypeus and the palpi fulvous, 
all the rest black; the third joint of the antennae longer than 
the fourth, the extreme apex of the terminal one, fulvous, 
thorax narrowly transverse, the sides rounded and widened near 
the base, nearly straight at the apex; the anterior angles scar- 
cely produced, the disc finely and rather closely punctured, with 
some obsolete depressions; elytra oblong, with a distinct flat- 
tened margin, closely and finely punctured, each elytron with 
a large black patch extending from before the middle to the 
apex, this colour does not extend to the sutural margin and 
ends in a narrow point or projection at the apex; tibiae, tarsi 
and the abdomen black, all the rest fulvous. 
Hab. New Guinea, Fly River (L. M. D’Albertis). Ramoi 
(O. Beccari). 
Allied in colouration to O. affinis Jac., but differing in the 
black head and antennae and in the shape of the black elytral 
patch, which extends quite to the lateral but not the sutural 
margin in the present species; a single specimen is however 
before me from Ramoi in which the black portion of the elytra 
touches the suture as well as the lateral margin but does not 
extend so high upwards as in the other specimens; as I can 
find no other differences I believe this to be a variety.
