BUPBLSTLLUE.—BY J. C. MOULTON. 161 
the upper edge is straight. In the other two specimens 
the band is broken at the suture by the turning in of 
the upper edge of the band, so as to give the appear¬ 
ance of two separate patches. This variety is men¬ 
tioned by Dr. K. Jordan in Novitates Zoologicae Vol. 
I. p. 488. It should be noted that in fresh examples this 
band is a beautiful creamy white ; but it quickly fades 
to a fulvous brown. 
The specimen I caught, was flying round some bushes 
in low swampy ground by the river, perhaps some ten 
feet up in the air; the bright midday sun (about n 
a. m.) shining on the green elytra giving it a very 
brilliant and conspicuous appearance. After about a 
quarter of an hour's circling round and round out of 
my reach, it settled on the underside of a leaf and with 
the aid of my topee I was able to catch it. An interest¬ 
ing feature about this insect is its resemblance, while 
flying, to the Hymenopterous species, Salius aviculus , 
(and to another Salius sp. near it, but with black 
antennae,) and to that remarkable Longicorn, Colobor- 
hombus fasciatipennis, which mimics the Hymenopteron 
so well. In flying, the simple pattern of the metallic 
blue-green relieved by alight transverse bar on the ely¬ 
tra of the Buprestid is exactly similar to this pattern on 
the wings of the Hymenopteron. However with elytra 
closed, the resemblance at once disappears, and as if 
cognizant of that fact, C. similis settled out of sight on 
the under side of a leaf ! 
The resemblances suggest an interesting example of 
Batesian mimicry where the two edible (?) Coleoptera 
are protected by colouring suitable to their surround¬ 
ings when at rest, but at the same time capable of 
assuming the warning pattern of the distasteful Hym¬ 
enopteron when in flight.
