184 Mr. G. Lewis on the Japanese Cleridfe. 



The ClericlEe also in the adult stage are, like the Erotylidse 

 and other families, very sliort-lived, and it is not often an 

 entomologist happens to be near their centre of emergence at 

 the opportune moment. Two such chances, however, occurred 

 to me in Japan. Once I saw Tillus in profusion at Naga- 

 saki on some brushes covered with bliglit ; but whether tliej 

 were attracted by the larvae of Coccinella, which came also, or 

 by the Aphidse I am unable to say. At another time I saw 

 Stigmatium in similar plenty, feeding on a species of Tomicus 

 which was busy drilling holes in the stems of a dead and 

 tangled mass of the Wistaria. The Cleridee as a family are 

 predaceous. 



For the convenience of students of the Japanese fauna I 

 have divided the species into two sections, which seems from 

 the material in hand to be a natural division, as each one 

 possesses conspicuous characteristics in tarsal structure and 

 dorsal punctuation. I have also been obliged, somewhat 

 unwillingly, to establish several new genera.

The fifteen species which are given precedence in this 

 paper have the punctuation of the elytra arranged in longi- 

 tudinal lines, and all the tarsal joints are more or less elongate. 



Spinoza, gen. nov. 



Cylindrical ; head subtransverse, less in width than the 

 thorax ; eyes prominent, coarsely granulate, circular in out- 

 line; palpi, last joint greatly enlarged, flat on either surface, 

 lobe-shaped. Antennae, first joint bulbiform anteriorly, con- 

 stricted at base; second smaller and shorter, not constricted ; 

 third rather elongate-cylindrical ; fourth and fifth stouter and 

 together measuring slightly more than the third; sixth toeighth 

 raoniliform and coequal ; ninth to eleventh form a lax club ; 

 terminal joint oval. Tarsi rather long and in size equal on 

 each tibia ; claws with a strong interior process stouter and 

 nearly as long as the claw itself. The elytra are nearly
