284 Mr. H. W. Bates' supplement to the 



fulvo-testaceis ; capite antice modice elongato, fronte 

 laevi ; thorace quadrato, postice sinuato-angustato, mar- 

 gine explanato-subreflexo, angulis posticis fere rectis ; 

 elytris apice leviter sinuatis, striis acutius quam in 

 D. agile impressis, interstitiis convexis alutaceis, 3io et 

 7nio seriato-punctatis. Variat pedibus piceo-rufis. Long. 

 6 — 7 mm. 



Oyama, in Sagami. 



Resembles D. agilis, but the head is perfectly smooth 

 above and not rounded behind the eyes, and the thorax is 

 less narrowed behind, with sinuated margins and nearly 

 rectangular hind angles. Palpi thickened as in D. 

 breviceps. 



Blechrus glabratus, Duftsch. 



Duftsch., Schaum, Ins. Deutschl., i., 1, p. 275. 



Junsai ; Sapporo. 



A universally-distributed insect in the north-temperate 

 zone ; in America ranging as far south as Mexico. 



Blechrus maurus, Sturm. 



Sturm, Schaum, I. c, p. 276. 



Bukenji; in dry arable fields early in spring. 



Bather more distinctly striated than European examples 

 usually are. 



Metabletus quadripunctatus, Schmidt-Goebel. 



Schmidt-Goebel, Col. Birm., p. 39. ? 



Yuyama. 



A single specimen agreeing with Schmidt-Goebel's 

 description, except with regard to the punctures on the 

 3rd interstice, which, according to him, are two in 

 number, one in the middle, the other far behind, — in 

 fact as in D.foveola and incequalis. The single Japanese 

 example is evidently an aberration, as there are two punc- 

 tures on the left elytron and four on the right. It would 

 be unsafe to found a new species on a unique specimen 

 in doubtful condition.
