upper edge of the antennal sockets, tubercles, basal spot on tegulae, basal' 

 half of front tibiae outwardly, basal spot on middle tibiae, and basal half 

 of hind tibiae yellowish ; calcaria pale, wings yellowish hyaline, the vena- 

 tion brownish. 



Second and following tergites with declined scattered hairs especially 

 on the margins where they simulate hair bands. 



Clypeus, supraclypeal area and sides of face longitudinally lineolate, 

 coarsely punctate with shallow punctures, those on the clypeus separated 

 by a little more than the diameter of one, front a little shining, rather 

 coarsely and closely punctured, vertex a little more discretely so. Meso- 

 notum opaque, similarly punctured, punctures separated by a little more 

 than the diameter of one, scutellum a little more shining, similarly punc- 

 tured ; mesopleura a little more deeply and unevenly punctured ; area of 

 propodeum strongly reticulate, the ridges very strong, sides of propodeum 

 obliquely punctured more or less separated from the basolateral areas 

 (which are weakly reticulate) by a Y-shaped carina, which also- separates 

 the sides from the posterior face. Sculpture of the posterior face irregu- 

 lar, partly concealed by appressed scattered plumose pubescence. 



First tergite smooth and shining, the second and following less shining 

 with scattered minute punctures, second a little contracted at apex ; 

 sternites similar to the tergites but the punctures stronger, all the mar- 

 gins a little translucent. A species of the aspect of the modcstus group. 

 Head about as broad as long, eyes a little convergent below. Recurrent 

 nervures interstitial or nearly so. 



9 . Length 7.5 mm. ; wing 5.5 mm. 



Described from 7 females collected at Ivaruizawa, SeptLiiilier 

 1913. In the material are three 5 taken at Okitsn in June, 

 1913, and one marked Japan which mav either represent the 

 same species or another closely allied.

Hylaeus paulus n. sp. 



$ . Smaller species, lateral face marks in a line against the orbit reach- 

 ing about to the level of the summit of the clypeus, tegulae with a yellow 

 spot. Collar more narrowed medially, punctures of the mesonotum 

 shallower. 



Black ; face marks in the type reduced to a line along the orbits, 

 a spot on the tubercles and tegulae, anterior tibiae with a short basal 

 outward stripe or spot, spot on outer base of middle tibiae and basal 

 1/3 of hind tibiae yellow, calcaria pale, flagellum pale brownish beneath ; 

 apical tarsal joints browni.sh; wings hyaline, the nervures brownish.
