Montr. which seems a closely allied or identical form. I am able 
to separate the specimens before me which are all of larger 
size than A. dorsalis and allied species, into two distinct forms; 
in one the transverse band of the elytra is always more or 
less widened at the suture and of a whitish colour; the anten- 
nae and legs are either entirely black or the femora are ful- 
vous; in the other form the elytral band is perfectly straight, 
broad, not widened and of a fulvous colour as well as the first 
two joints of the antennae, the others and the legs are black. 
This form is probably the A. rubrozonata. 
24. Aulacophora basalis, n. sp. 
Black; head, antennae, thorax and legs flavous; elytra very 
finely punctured anteriorly, black, the base to a smaller or 
greater extend, flavous. 
Length 2 lines. 
Head impunctate; antennae half the length of the body, enti- 
rely flavous, the second joint short, the third more than double 
the length; thorax twice as broad as long, the sides straight 
at the base, rounded before the middle, surface entirely im- 
punctate, transversely grooved, the groove extending to the sides 
and of sinuate shape; scutellum flavous; elytra with a few 
rows of finely impressed punctures at the anterior portion, the 
posterior one impunctate, the basal portion to a variable extend 
flavous, the rest black. 
Hab. Elephanta (Beccari). 
I cannot find any published description of a species of Awla- 
cophora with which the present insect agrees and of which six 
specimens were obtained. The flavous anterior portion of the 
elytra assumes in some specimens the shape of a narrow trans- 
verse band, in others it is limited to the basal margin only, 
but is present in all the specimens before me.
