CossonidoE. of Japan. 35 
Genus 12. Xenomimetes (nov. gen.). 
Corpus cylindricum, calvum, dense et profunde sculp- 
turatum : capite convexo ; rostro brevi, lato, sed capite 
sensim angustiore, et parallelo (nee triangulari), depresso ; 
scrobe brevi, profunda, curvata, infra oculum desiliente ; 
oculis longe ante marginem prothoracis sitis, rotundatis, 
valde prorainentibus : prothorace subcylindrico, pone mar- 
ginem anticum transversim constricto : scutello rotundato, 
distincto : metasterno elongato : elytris cylindi'icis, ad 
apicem ipsum paulo singulatim divaricatis. Antennce bre- 
viusculse, crassiusculffi, in medio (aut forsan mox ante 
medium) rostri insertse ; scapo recto, leviter clavato ; 
funiculo 7-articulato, art.° 1"'° subquadrato (reliquis ma- 
jore, sed baud magno), sequentibus transversis, latitudine 
paulo crescentibus ; capitulo abrupto, ovato, apice obscure 
annulato. Pedes validi, antici ad basin fere approximati, 
intermedii distantiores, postici valde distantes : femoribus 
muticis: tibiis su})flexuosis (extus quasi paululum exca- 
vatis), ad apicem externum in uncum magnum inflexum, 
necnon ad internum in spinam parvam productis : tarsis 
elongatis, gracilibus, art.° l""" longiusculo, 3"° fere sim- 
plici (i.e. vix dilatato et vix bilobo), ult.™" elongato, 
graciusculo, unguiculis parvis armato. 
Obs. — Corpus Hylurgi formam simidans, sed rostro, 
tibiis abdomineque Cossonidis omnino congruit. A Syn~ 
tomocero (^ E remotes, olim) ac Stenoscelide difFert, inter 
alia, rostro (quamvis brevi) conspicue longiore, minus 
incrassato, et lineari (nee triangulari), antennis aliter con- 
structis, elytrisque ad apicem sensim divaricatis.

The facies and sculpture of the remarkable Cossonid 
from which the above structural diagnosis has been com- 
piled have so much in common, at first sight, with certain 
5M^-Curculionideous forms (like Hylastes) of the Scoly- 
tidce, that it must clearly be regarded as the type of 
another group in the vicinity of Eremotes (or Syntomo- 
cerus), which infests the pine trees at a high elevation 
in the Canarian archipelago. Yet its rostrvim, although 
short and broad, is neither so short nor so broad as in that 
genus, and, moreover (instead of being thick and trian- 
gular), it is parallel and depressed, and appreciably nar- 
rower than the head. Its antennae,. also, are very different 
from what obtains in that group, being less thickened ; 
and there is not that peculiarity, which forms so marked
