minute ; its metasternum is very short, and the first seg- 

 ment of its abdomen is likewise more abbreviated than is 

 usually the case amongst the Cossonida. 



[38. LYMANTES (Schonherr,G^w.<tf 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. scrobicoltis, 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. APAROPKION (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 which I have 

 extracted concerning it from Lacordaire. Indeed even 

 the latter does not appear to have been acquainted with 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 elytra (which latter are oval and con- 

 vex), the head minute, the rostrum (into which the an- 

 tennre are inserted towards the apex) rather long and 

 subcylindric, and the third tarsal joint bilobed.] 



[40. OODEMAS (Boheman, Res. 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 Lacordaire. 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,
