KEY TO THE SPECIES OF SINOXYLON 



1: Submarginal carina along lateral margin of elytron sharply elevated pos- 

 teriorly, curving inward to sutural margin and forming the anterior 

 margin of apical concavity; antennal club flabellate_ anale Lesne, p. 58. 

 Submarginal carina along lateral margin of elytron not curving inward, 

 but following outline of lateral margin; apical declivity not margined 

 anteriorly; antennal club flabellate, or with segments strongly trans- 

 verse 



2. Antennal club flabellate, each segment four times as wide as long, first 



segment not subtriangular conigerum Gerstacker, p. 60. 



Antennal club not flabellate, each segment twice as wide as long, first 

 segment subtriangular 3 



3. Elytra with costiform tubercles at anterior margin of apical declivity 4 



Elytra without costiform tubercles at anterior margin of apical de- 

 clivity japonicum Lesne. p. 61. 



4. Each elytron with three costiform tubercles at anterior margin of apical 



declivity, and a triangular, compressed tubercle at middle of declivity 



along sutural margin ruficorne Fahraeus, p. 62. 



Each elytron with one costiform tubercle at anterior margin of apical 

 declivity and with two conical tubercles placed transversely at middle 

 of declivity, the outer tubercle short and obtuse at apex, the inner 

 one long, acute at apex, and placed some distance from sutural 

 margin sexdentatum (Olivier), p. 63.

Body short. Black or dark reddish brown, basal half of elytra, 

 posterior angles of pronotum usually more reddish, the antennae, 

 palpi, legs, and abdomen in part brownish yellow. 



Head with four small tubercles along anterior margin, densely, 

 coarsely granulose, and sparsely clothed with short, recumbent, whitish 

 hairs on front, with long, fine, longitudinal, parallel costae on occiput ; 

 clypeus finely sparsely granulose, with a transverse, sinuate carina 

 near anterior margin, the carina angulate at middle and extending on 

 each side to tooth at base of labrum; clypeal suture distinct; labrum 

 very finely, densely punctate. Antennal club strongly flabellate, 

 sparsely clothed with fine, recumbent, inconspicuous hairs; first seg- 

 ment of club narrowest, sides nearly parallel; second wider than 

 length of first seven segments united ; third finely grooved on anterior 

 surface. 



Pronotum slightly wider than long, widest near middle; sides 

 slightly rounded posteriorly, more strongly converging anteriorly, 

 with a small, unciform tooth at apical angles ; posterior angles broadly
