4. Tibiae black; front devoid of dense oppressed hairs directed strongly out- 



ward from bases of antennae 6.

5. Femora black ; front with dense, appressetl hair which is dix'ected strongly 



outward at the base of the antennae. (17) (Ind.a) capillata, new species. 



Femora of last two pairs of legs bright red ; f /out with scanty, erect hairs

6. Second intercubital vein .straight, joining the radius at a sharp angle; fir.st 



tergite at most with only a few miiuite punctures on its medio-anterior 



aspect 7. 



Second intercubital vein sinuous, joining the radius in a broadly rounded 

 angle ; first tergite usually with a broad, median patch of dense, minute 

 punctures on its anterior aspect ; tegula nearly black, with two separate 

 marginal grooves, one on the outer and the other on the posterior margin, 

 both terminating in an abrupt, inward directed hook at the outer hiud 

 angle (13) (Japan. China) rufomandibulata Smiih. 



7. Propodeal areuia without additional longitudinal ciirinae between the usual 



two lateral and median cariuae 8. 



Propodeal areola with an addit.onai longitudinal carina on each side of the 

 median carina, between the median and the lateral carinae.

 areola as d scribed above (15) (China) brevicarinata, new species. 



9. Anterior, constricted portion of first sternite punctate or coarsely coria- 



ceous, without a definite median keel fianked by deep, short grooves 

 supported on the outside by high, sharp carinae ; tegula with a groove or 



impression, at least on posterior margin 10.
