minute ; its metasternum is very short, and the first seg- 
ment of its abdomen is hkewise more abbreviated than is 
usually the case amongst the Cossonidce. 
[38. Ltmantes ( Schonherr,G^e?z. et Spec. Cure. iv. 1085. 
1838). — The present genus, together with the two follow- 
ing, I have not been able to inspect ; and consequently 
the few diagnostic characters which are given of it in my 
summary I cannot vouch for as being in precise accordance 
with the type. It seems to have been founded on a single 
species, from North America, — the S. scrobicoUis, Bohm, 
— which is described as rather elongate and oblong, of 
either a black or brownish hue, somewhat variolose an- 
teriorly and beneath, and with the elytra (which are not 
wider than the prothorax) deeply punctate-striate. Its 
metasternum is much abbreviated ; its rostrum is robust, 
and separated by a deep stricture from the forehead ; its 
eyes are small and depressed ; its prothorax is elongate- 
quadrate ; and its feet are short and filiform.] 
[39. Aparoprion (Hampe, Wien. Ent. Monatsch. v. 
68. 1861). — As just stated, this genus (although Euro- 
pean) I have not been able to procure for examination ; 
and consequently I cannot speak with any precision con- 
cerning the very few diagnostic features v/hich I have 
extracted concerning it from Lacordaire. Indeed even 
the latter does not appear to have been acquainted Avith it 
except through the very short and imperfect description 
given by M. Hampe ; and we may presume therefore 
that it is of great rarity in collections. It was established 
to receive a small insect (the A. costatum) from Tran- 
sylvania, which is said to be of a brownish colour and 
finely pubescent, — with the prothorax subglobose and much 
narrower than the elyti-a (which latter are oval and con- 
vex), the head minute, the rostrum (into which the an- 
tennas are inserted towards the apex) rather long and 
subcylindric, and the third tarsal joint bilobed.] 
[40. OoDEMAS (Boheman, Bes. Eugen. 138. 1859). — 
This genus, like the two preceding ones, I have not been 
able to inspect ; and my short diagnosis is, consequently, 
a mere epitome of the one given by Lacordaii'e. It ap- 
pears to have been founded by Boheman to receive a small 
insect taken near Honolulu, in the Sandwich Islands ; 
which is described as regularly oval, glabrous, shining,
