58 Mr. G. Lewis on ^roijYidiSd from Japan. 



Head irregularly punctate, with two oblique impressions 

 between the antennae ; thorax marginate laterally, coarsely 

 punctate, somewhat densely at the sides, sparsely in the 

 middle, with a transverse space before the scutellum smooth ; 

 the elytra are finely punctate-striate, the interstices with 

 smaller punctures scattered irregularly ; at the base there 

 is a broad yellowish fascia, which leaves a humeral spot, and 

 the usual hamate pattern behind the scutellum, black, and 

 another before the apex, which leaves the suture and outer 

 edge black. Beneath, the sternal plates are similar to those 

 of M. tricolor, as noted below. 



Two specimens, from Nishimui'a in Yamato, are all I 

 obtained. 



Microsternus tricolor. 



Elongato-ovatus, obscure rufo-brunneus, capite thoraceque parce 

 punctatis; elytris temiiter punctato-striatis, interstitiis inconspicue 

 puncticulatis, luteo-fasciatis ; pedibus brunneis ; antennis infus- 

 catis. L. 4 mill. 



Head and thorax irregularly and sparsely punctate, reddish 

 brown above, but darker beneath, marginate at the sides ; 

 elytra with a black humeral spot surrounded by a yellow 

 band, which is narrow at the outer edge, but posteriorly about 

 as broad as the black spot ; in the middle of the elytra is a 

 broad irregular black band which, on reaching the fourth 

 stria, becomes concolorous with the head and thorax, and at 

 the second stria extends up to the scutellum ; before the apex 

 is a second black band with even edges, and it is separated 

 from the central band by a yellow fascia, broadest at fourth 

 stria ; apex reddish yellow. The prosternal process is trian- 

 gular, marginate and impunctate ; the sides of the pro- 

 sternum are thickly and coarsely granulate; mesosternum 

 inconspicuous. 



I obtained five examples at Yuyama, in Higo, in May 

 1881. 



Microsternus Jiigonius. 



Oblongo-ovatus, piceus ; thorace rufo maculato ; elytris punctato- 

 striatis, rufis, nigro 6-maculatis ; antennis pedibusque rufo- 

 brunneis. L. 2| mill. 



Head and thorax with large scattered punctures, first wholly 

 piceous, second with a longitudinal reddish mark on each side 

 on the disk in a line behind the eyes ; the thorax has a 

 broad, raised, lateral margin, parallel to which is a somewhat 

 deep furrow ; in front of the scutellum is a crenulate arched 

 line (corresponding a little to the lines common in Abrcei),
