head and thorax, and have an iridescent gloss ; the striae 
are strongly and sharply impressed, with the usual scutellar 
striolc and interstitial puncture. The two basal joints of 
the antenna; are yellow, the rest tawny-brown.

Osaka. Also in China; at Kiu-Kiang (Yang-tsze), 
Shanghai, Ningpo, and Foochow ; apparently a common 
insect. 
M. Morawitz appears not to admit Anoplogenius as 
distinct from Stenolophus. The structural differences are 
indeed very slight, but Anoplogenius may be knoAVU at 
once by the absence of the abbreviated scutellar stria.

Very closely allied to the European S, vespertinus. The 
thorax is decidedly shorter, Avith more rounded basal mar- 
gin and Avith the marginal rim more strongly raised round 
the hind angles.

MoraAvitz states that there is no difference l^etAveen Yesso 
specimens and others from Southern Kussia. I have not 
been able to obtain specimens of pj-oxiinus, to make the 
comparison ; but Mr. LcAvis's specimens agree very Avell 
Avith Dejean's description. They differ only in their rather 
smaller size from the Chinese S. iridicolor (Redtenb.).
