34 Mr. T. Vernon Wollaston on the 
mention tlieir larger size, more parallel outline, and more 
elongate prothorax, they differ considerably in the forma- 
tion of their rostrum, which is neither thick and triangular 
like that of the typical Rhyncoli, nor comparatively slender 
and linear as in the normal members of Phloeophagus, but 
somewhat intermediate between the t^vo, — being short 
and incrassated, but nevertheless conspicuously parallel 
throughout (though not quite so short and broad, nor so 
depressed, as in Xenomimetes\ Its scrobs, too, is very 
differently constructed from that of Rhyncolus, — being 
short, deep, wide, and auriculiform at its base, and then 
suddenly narrowed and bent downwards, at a sharp angle, 
beneath the eye. In addition to this, its eyes are larger 
and more prominent than those of the Rhyncoli (and the 
Phloeophagi), its antennae are implanted behind (instead 
of before) the middle of the rostrum, and its tibias are 
Produced at their inner angle into a more distinct spinule. 
n its thickened antenna? and limbs, and short feet, it is 
more, perhaps, on the Rhyncolus than the normal Phloeo- 
phagus type.

The black hue and shining (though nevertheless deeply 
sculptured) surface of this beautifid Cossonid, added to 
its structural features to which I have above alluded, will 
suffice to distinguish it from everything else with which 
we are here concerned. The four examples from which 
the description has been di'awn were taken amongst fir- 
trees and funguses, by Mr. Lewis, at Hiogo, in the island 
of Nipon.
