Rhynchophorous Coleoptera of Japan. 129 
This will cause no confusion, and the same cannot be 
said of a readjustment of the sexual characters which 
should eventually be proved to be itself erroneous. 
The question can be settled beyond dispute by the 
dissection of fresh examples; and if J can obtain them 
J hope to solve it in that way. 
Crossorarsus, Chap. 
This Oriental genus is represented by three species. 
Crossotarsus chapuisi, sp. n. 
Fem, Sub-elongata, picea, nitidissima ; capite dense ac rugose 
punctato; prothorace irregulariter punctato, punctis ante 
suleum et versus basim crebrioribus; elytris striato-punctatis, 
interstitio 30 ad basim dilatato, laevi, ad apicem subangustatis, 
leniter declivibus, apice pilis aureis ciliato, supra depressionem 
posticam angustam sublinearem producto, angulo externo vix 
perspicue elongato ; abdominis segmento apicali fortiter excavato- 
impresso ; tibiis posticis dilatatis ad apicem in lobos productis, 
Long. 8 mm, 
One specimen, Higo. 
More elongate than the majority of the genus, shining piceous, 
smooth and regularly cylindrical. Head with front subquadrate, 
very closely and rugosely punctured, the punctures longitudinal, 
with an indistinct median depression, vertex with three shining 
longitudinal vittze separated by punctured spaces, eyes rather large 
and prominent, subcircular, antenne with scape enlarged towards 
the base or inner side, but not produced, funiculus inserted at 
apex of scape. Prothorax oblong, not strongly emarginate, 
posterior angles of emargination rather prominent, median sulcus 
fine, surrounded by a smooth cordate area; punctures longi- 
tudinally oval, sparse over apical half, closer at base and over a 
patch in front of sulcus, lateral margin with two or three deep 
asymmetrical pore-like punctures behind middle. Scutellum 
indistinguishable. Elytra double as long as prothorax, with sides 
narrowed and slightly constricted at apex ; striate, the striz with 
an irregular single row of punctures grouped in pairs, 3rd and 4th 
conjoined at base, interstices smooth, flat, with very fine irregular 
punctures, 3rd dilated at base with a few stronger punctures; 
gently depressed towards apex, with the striz at first deeper and 
then obliterated before posterior margin, interstitial punctuation
