Pselaphidce of Japan. 331 



Diartiger spinipes, n. s. 



Rufescens, tenuiter flavo-setosus, elytrorum apice 

 abdominisque latere ad basin dense flavo-pubescentibus ; 

 capite thoraceque dense, elytris parce subtiliter, punc- 

 tatis ; abdomine nitido, longius setoso, basi in medio 

 fovea maxima impressa. Long. 2^ mm. 



Mas, pedibus intermediis, trochanteribus spina per- 

 elongata, femoribus spina elongata curvata, tibiis late- 

 raliter compressis. 



This species appears to be closely allied to 1). fossu- 

 latus, but the individual before me is rather larger than 

 the largest of that species, has the antenme slightly 

 more elongate, the elytra much more sparingly punctate, 

 and the spines on the middle legs of the male of remark- 

 able elongation. In D.fossulatus a well-marked patch 

 of golden pubescence extends along the middle of the 

 breast in each sex, but is more conspicuous in the male ; 

 in the male of D. spinipes this pubescence is absent, and 

 the hinder part of the metasternum is broadly impressed. 



A single individual was found at Yuyama, May 10th, 

 1881.
