NEW SPECIES OF ACULEATE HYMENOPTEEA FROM JAPAN. 35 



thickly haired than the basal. The front coxse are yellowish, the four 

 hinder black ; the legs are thickly covered with long pale hair. 



The males of the recorded Japanese species of Dielis are 

 known, and the female of the present species is probably un- 

 described. Characteristic are the rufo-testaceous legs and the 

 rufous apical segments of the abdomen. 



EUMENES MICADO, Sp. nOV. 



Black; the antennal tubercle, a large irregular mark, about three 

 times longer than wide, on either side of the base of the clypeus, a 

 small line on the upper side of the outer eye-orbits, the base of the 

 pronotum narrowly, the base of the propleurs broadly — the mark 

 extending to near the centre above and half-way below — the greater 

 part of the tegulaB, two large marks, broader than long, on the base of 

 the scutellum, the post-scutellum, a large irregular mark, broader than 

 long and with irregular edges, on the sides of the metanotum. Two 

 slightly smaller ones below them, these having the outer side straight, 

 the inner rounded and irregular ; the apex of the first abdominal seg- 

 ment narrowly, and of the second more broadly — the band narrowed 

 in the centre — yellow. Legs black, the knees, the anterior tibiae in 

 front, the basal half of the four posterior and the spurs testaceous. 

 Wings hyaline, tinted with fuscous-violaceous, the nervures and stigma 

 dark fuscous. ? . Length, 18 mm. 



Hab. Sharo-Kowa, Japan {George Lewis). 



Antennae brownish at the apex, Front and vertex closely and 

 distinctly punctured, sparsely covered with short fuscous pubescence. 

 Clypeus sparsely punctured, the apical part less strongly, more de- 

 pressed, and with a curved broad incision on the apex. Mandibles 

 brownish at the apex. Thorax above coarsely and closely punctured, 

 the metanotum more coarsely than the rest. Pleurae less strongly and 

 closely punctured, the apex of the meso- and the base of the meta- 

 pleurae more broadly smooth. Petiole longer than the second segment, 

 the dilated part strongly and closely punctured, the punctuation closer 

 and stronger at the apex ; the second segment closely and much more 

 finely punctured. 



This species is closely related to E. punctata, but that species 

 is smaller (13 mm.), has the head and thorax densely pilose, the 

 clypeus shorter compared with its width, the antennal tubercle 

 more distinctly dilated above, the apex of the metanotum more 

 distinctly roundly dilated, its petiole is more distinctly longer 

 compared with the second segment ; the abdomen is more and 

 the thorax much less largely marked with yellow, the metanotum 

 is less rugosely punctured, and more clearly furrowed ; and the 

 scutellum has a more oblique slope, and is less rounded.
