SOME NEW UENERA AND SPECIES OF HYMENOPTERA. 239 



Abdomen shining, sparsely punctured ; the apical segments thickly 

 covered with long white hair ; the basal half of the pygidium is strongly 

 punctured, and is thickly covered with long pale fulvous hair ; the apex 

 is smooth, rufous, and is keeled down the middle ; the epipygium is 

 closely and finely punctured. 



TiPHIA BICARINATA, Sp. IIOV. 



Nigra, punctata, longe hirsuta ; alls fusco-violaceis ; metanoto 

 bicarinato. (?. Long. 16 mm. 



Hab. Japan (George Lewis). 



This species is larger than any of the recorded Japanese 

 species, from which it differs (as it does also from the Indian) in 

 having only two keels on the median segment. 



Scape of the antennae shining, bearing large deep punctures and 

 long pale fulvous hairs ; the basal three joints of the flagellum shining, 

 thickly covered with glistening fulvous hair ; the rest of the flagellum 

 opaque, covered with a dull pale down. Front and vertex closely and 

 strongly punctured ; there is a smooth space on the outer side of the 

 hinder ocelli, which is continued across behind them by a space having 

 only a few small punctures ; the part immediately behind the ocelli is 

 strongly punctured. Front thickly covered with long, the vertex with 

 shorter, fuscous hair ; in front of the ocelli there is a smooth space — 

 somewhat dagger-shaped in form — broad at the base, narrowed and 

 sharply pointed at the apex. Clypeus smooth and shining in the 

 middle ; the base and sides shagreened. Mandibles broadly piceous in 

 the middle ; the lower side fringed with long pale golden hair at the 

 base. The pronotum on the perpendicular base closely punctured, 

 except on the lower side in the middle ; the upper part coarsely punc- 

 tured, except a broad somewhat curved space at the base. The middle 

 of the mesonotum is slightly depressed, closely and coarsely punctured, 

 the sides are bordered by a row of large deep punctures, closely united 

 together, followed inwardly by a row of larger ones, fewer in number, 

 and more widely separated ; inside ot these again is a smooth space, 

 with a large puncture near its centre. Scutellum closely punctured at 

 base and apex, the middle smooth. Median segment shagreened, 

 opaque, finely longitudinally aciculated at the apex ; in the middle are 

 two stout keels, which hardly converge towards the centre. The base 

 of the propleurse bears moderately large punctures, closely united 

 together at the extreme base, widely separated and scattered over the 

 rest ; the lower half is closely obliquely striated, the stri^ somewhat 

 coarser towards the apex ; the whole shining. Mesopleuras strongly 

 punctured, opaque, thickly covered with long white hair. In the 

 middle of the metapleuras is a shallow curved furrow ; the upper part 

 at the base strongly obliquely striated ; the lower smooth, very finely 

 striated ; the apex is also finely striated. Legs black, the projection 

 on the apices of the femora piceous ; the coxae, trochanters, and 

 femora smooth, sparsely covered with soft white hair ; the fore tibiae 

 slightly, the four posterior very thickly, covered with white hair; 

 coarsely punctured on the outer, smooth on the inner side ; the outer 

 row of broad spines pale and fulvous ; the calcaria testaceous. The 

 petiole shining, smooth, covered with long fuscous hair, more sparsely
