This species appears to be a true Donacia, the insertion of the 
antennze, the almost contiguous strongly exserted front coxe, the 
form of the prothorax, and I think all other structural characters 
being quite as in that genus. It is an insect of a pale, washed- 
out, testaceous-brown colour, with a bright greenish gloss in 
certain lights. The head and prothorax are almost devoid of 
puncturation, and are semi-opaque, owing to being minutely 
coriaceous. The prothorax is a little rugulose near the base, all 
its angles well defined and laterally prominent. The antenne and 
legs are of a brighter testaceous colour than the general surface, 
each joint of the former a little darker at the apex.

This species does not approach any yet described in colouring 
—and it is certainly not a variety of any of a fairly long series 
of species in my collection. Nevertheless the species of this 
genus are so subject to variation in markings that it is not im- 
probable a good many now called species may eventually be 
found to be varieties. I cannot, however, suggest any species of 
which this may be a variety, and in any case it is convenient 
that well-marked varieties should have a distinctive name. In 
the present insect the dark fascize are so wide as to occupy the 
greater part of the elytra, the fulvous colouring appearing as a 
fascia, occupying about the middle one-third of the elytra, its 
front margin commencing on each elytron a little behind the 
scutellum on the suture and running obliquely hindward to the 
lateral margin (which it does not quite touch) at about a third 
of its length ; the hind margin of the fulvous part of the elytra 
commencing on the suture a little behind its middle and running 
obliquely towards (but not quite touching) the lateral margin at 
about two thirds of its length from the base.
