552 Mr. T. Vernon Wollaston on the 
60. HoMALOXEXUS {nov.ffeii.). — I am indebted to John 
Gray, Esq., for the very curious little insect, from the 
West Indian island of St. Domingo, to receive which the 
present genus is proposed ; and it is so perfectly distinct 
from every other Cossonideous form with which I am 
acquainted that I had some hesitation at first in admitting 
it into the present fQ,mily at all ; nevertheless the unmis- 
takeable structure of its abdominal segments, in conjunc-. 
tion with its tibial hook and other details, are sufficient I 
think to indicate its affinities. Its distinctly annulated 
club however, added to its elongate, slender, straightened, 
and longitudlnally-strigose rostrum, into which the antennae 
are implanted at the apex, are anything but in accordance 
Avith the usual modifications of the Cossonid type, being 
prima facie somewhat suggestive of certain groups amongst 
even the Erirlii aides, — an analogy which (however super- 
ficial) its uni-dentate femora would not tend to invalidate. 
But apart from these various peculiarities, Homaloxenns 
is remarkable for its rather broad and extremely depressed 
body — which is subopakc, ferruginous, and sjiarlngly 
clothed Avith a very minute decumbent subclnereous pubes- 
cence ; for its entire prothoracic disk being very curiously 
flattened, or impressed ; for its autenna^ being long and 
slender, with the second joint of their funiculus (which is 
remarkably lax) conspicuously lengthened ; and for its 
tibine (which have their hook very small) being barbed, or 
pencilled, at their ajiex with fulvescent hairs. Its scutellum 
is largely developed, its metasternum is somewhat short, 
and the third articidation of its feet is much expanded and 
bilobed. 
61. Stenotis (Wollaston, Ins. Mad. 316. 1854).— 
The JNIadelran genus Stenotis is founded on one of the 
most remarkable little Cossonids with Avhich I am ac- 
quainted, — its extremely narrow, elongate outline, palHd 
luie, and subdeprcssed, delicately sericeous surface, added 
to the excessive length and slenderness of its rostrum, its 
elongated pro thorax and metasternum, its thickened legs, 
and its unusually Avidened and deeply bilobed third tarsal 
joint, giving It a character essentially its own. Its sub- 
sericeous surface indeed, and general structure, shoAv it to 
belong, unmistakeably, to the same department as Mesites ; 
nevertheless I believe that its nearest known ally Is the 
South-American genus JEucoptus, from Brazil and the 
region of the Amazon, — with which it has a good deal in
