head markings are different and there are only two spines on the 

 sides of the metanotum. 



Ancistrocerus densepilosellus, sp. n. 



Black, the clypeus, labrum, middle of mandibles irregularly, 

 under side of antennal scape, a line on apex of pronotum, one on 

 the apices of the basal four abdominal segments above and on the 

 basal two below, the basal dorsal two narrowed laterally, the line on 

 second ventral widened laterally, the apices of the femora narrowly 

 and 'the greater part of the tibiae and tarsi, pale yellow; wings 

 hyaline, the stigma fuscous, the nervures darker coloured. Tegulae 

 black. Head and thorax densely covered with moderately long pale 

 pubescence. ^ . Total length 8 mm. 



Clypeus as wide as long, transverse above, the apex with a dis- 

 tinct semicircular incision. Antennae thickened towards the apex, 

 the apical two joints brownish beneath, the hook of moderate thick- 

 ness, reaching to the base of the joint. Base of thorax transverse, 

 with acute projecting angles. Post-scutellum more obliquely sloped 

 than the scutellum. Sides of metanotum bluntly margined. The 

 second abdominal segment is longer than it is wide at the apex ; the 

 apices of the segment flat, not strongly punctured. 



Ancistrocerus apiciornatus, sp. n. 



Black, the apices of the abdominal two basal segments, a short 

 line on the sides of the apex of the second ventral, the clypeus in 

 the male, a line on the base below on the antennal scape in the male 

 and the greater part of the four front tibiae and tarsi, the base of the 

 hind tibiae and the basal joint of the hind tarsi, pale yellow ; wings 

 highly iridescent, violaceous on apical half, the stigma and nervures 

 black. Apical joints in male antennae brownish below, thickened, 

 without a hook. Female clypeus a little wider than long, its apex 

 slightly depressed in the centre, shortly, bluntly tuberculate laterally. 

 Clypeus in male a little wider than long, its apex with a rounded, 

 shallow incision. ? and ^ . Total length 7 mm. 



A slender, narrow species. Shining, densely covered with short 

 white pubescence. Base of thorax transverse, raised. Parapsidal 

 furrows distinct. Scutellum with a w^ide furrow which does not 

 reach the base or apex ; it is widened towards the apex, the apex 

 itself being acutely pointed. Post-scutellum with a curved furrow in 

 the middle, the base more strongly punctured than the apex. Sides 

 of metanotum broadly rounded, closely reticulated. Upper apical 

 two-thirds of propleurae irregularly striated-punctured ; meso- and 

 metapleurae smooth, the former more shining than the latter. Basal 

 segment of abdomen strongly punctured, the apical longitudinal 

 furrow long and deep. 



The three species described above were sent to me by Mr. T. 

 Fukai, Secretary of the Entomological Society of Japan, of 

 Konosu, Saitama.
