HYMENOPTERA FROM JAPAN AND THE PACIFIC. 271 



^copically and closely pilose, stout, the apex involute ; 

 the third joint a little shorter than the fourth, the 

 other joints not clearly distinguishable except towards 

 the apex. Head large, cubital slightly projecting 

 behind the eyes ; the occiput, vertex, and front shin- 

 ing, except the latter at the sides, which are rather 

 strongly punctured ; the face is coarsely rugose. 

 The excavation on the front is deep, and extends 

 upwards so as to enclose the lower ocellus, the 

 triangular prolongation of the depression separating 

 it from the other two, which are placed one on each 

 side of the depression. The mandibles are curved, 

 piceous at the base ; there is a small subapical tooth. 

 Palpi thick, longish, pilose. Thorax in front (at the 

 sides and above) coarsely rugose, the depression on 

 the pronotum crenulated ; mesonotum and scutelluni 

 strongly punctured; the mesopleura has large scat- 

 tered punctures, and longish scattered hair. The 

 metanotum is coarsely reticulated; the metapleura 

 coarsely punctured. Petiole shining, strongly punc- 

 tured, the punctures running into reticulations ; the 

 centre is raised, the elevation being bounded by two 

 stout keels ; along the sides at the base is a furrow of 

 moderate width. The rest of the abdomen is smooth, 

 shining, and impunctate. The abdomen is a little 

 longer than the thorax ; it is somewhat narrower 

 than the thorax, is of nearly equal width from the 

 second segment, and laterally at the apex is obliquely 

 truncated. The ovipositor is almost as long as the 

 thorax and abdomen together, and issues from the 

 lower side of the abdomen. The pobrachial transverse 

 nervure is interstitial, the transverse praebrachial is 

 united to the cvibitus near its origin; the recurrent 

 nervure is received in front of the first transverse 

 cubital; the second cubital cellule is a little shorter 

 than the first. Legs stout, covered with white hair ; 

 the hind coxae and femora punctured strongly, the 

 others scarcely punctured ; the hind tibiae are much 

 longer than the tarsi. 



Length of body, nearly 12 mm. ; of terebra, 11 mm.
