A short, compact species, the head short, eyes not very strongly con- 

 vergent below, supraclypeal area, a little contracted medially, expanded 

 and elevated above, bearing a fine furrow which extends over the front 

 to the anterior ocellus. CoUai acute in front, narrowed or subinterrupted 

 in the middle. The recurrent nervures interstitial or nearly so. 



$ Scape broader than long, about five times as wide as the pedicel, 

 strongly concave on the side next the head. 



Black ; clypeus, spot rounded above on supraclypeal area, sides of 

 face to above the antennae rounded a little away from the orbit above, 

 longitudinal stripe on outer side of scape, spot on tegulae and tubercles, 

 knees, tibiae and tarsi, except large subapical inner infuscate spots on 

 anterior and middle tibiae and a dark subapical mark surrounding hind 

 tibiae subapically, yellow. 



Eighth sternite with the basal process strong, dorsoventrally exoanded, 

 the apical process elongated, strongly chitinized as seen from the side 

 with a carina ending in a tooth about half way to the end, the end is 

 acuminate and regularly curved ventrally from the plane of the sternite. 

 Stipes regularly rounded at apex with a few plumose brown hairs, exceed- 

 ing a little the sagittae and the inner margin curved for their reception, 

 the narrowed portion longer than the broader basal portion. 



9 Length 6.5 mm. ; wing 5 mm. ; $ 5.5 mm. ; wing 4.5 mm. 



Described from nine ? and one $ collected at Kaniizawa, 

 September 1913.

Hylaeus gnathylaeoides n. sp. 



$ Clypeus with a broad longitudinal mark not attaining the margin 

 (and 2 subapical lateral spots in the paratype) and (paratype) a spot on 

 the supraclypeal area yellow. Supraclypeal area slightly contracted in the 

 middle, a little expanded and strongly elevated and channeled above, the 

 channel extending feebly to the anterior ocellus. 



Black, longitudinal mark on clypeus, sides of face to the level of the 

 summit of the clypeus and triangularly extended along the orbit a little 

 above the superior margin of the antennal sockets, sometimes a supracly- 

 peal spot, band on collar narrowed and interrupted medially, large spots 

 on tegulae and tubercles, anterior knees, stripe on tibiae outwardly and 

 tarsi, outer base of middle tibiae, and basal half of hind tibiae yellow ; 

 flagellum beneath, tarsi and margins of abdominal segments brownish, 

 calaria pale. Wings hyaline, the venation brownish. 



Clypeus, supraclypeal area, and sides of face longitudinally lineolate 

 or striolate, with shallow, sparse indications of punctures ; front and 

 vertex a little shining, strongly and closely punctured ; mesonotum opaque
