SIGALPHIN^. 

 RHYSSOSIGALiPHlIS gen. nov. 



9 . — Abdomeu with one visible segment; its apex deeply roundly 

 incised, the sides of" the incision forming longish, stout teeth ; the 

 back coarsely, rugosely punctured. Radial cellule short, acute at 

 the apex. Transverse median nervure received clearly beyond the 

 transverse basal ; it does not extend to the apex of the wing, so that 

 the pobrachial and the podiscoidal cellules are not separated, the 

 anal nervure is only indicated at the base, it is interstitial ; the po- 

 discoidal and the anal cellules are not separated ; there is a distinct 

 axillary transverse nervure in the axillary cellule. In the hind 

 wing the radius is almost obsolete ; the cubitus extends to the mid- 

 dle ; there is a large pobrachial cellule, wide at the apex,, where it 

 is closed by a stout, slightly oblique nervure, it is bounded below 

 by a nervure which curves roundly upwards and reaches to the 

 transverse nervure; the radius and cubitus are indistinct ; the other 

 nervures stout. Malar space large. Mesonotum trilobate ; apex of 

 clypeus slightly waved. Antennse placed high up on the face. Meta- 

 notum areolated, its apex with a steej) slope bordered above. Abdo- 

 men sessile, margined at the base. 



Comes nearest to Urosigalphus Ashm., which maybe known from 

 it by having the "apex of abdomen without or with only a slight 

 eraargination," not deeply emarginated and stoutly spined. as in the 

 present genus. The ovipositor issues from the middle of the abdo- 

 men ; the hypopygium is depressed in the middle, the apex bifove- 

 ate ; the sides raised, the raised part continued onto the teeth. 



Rhyssosigalphus rugosus sp. nov. 



Black, the fore legs and the apex of middle femora and their tibia' rufotesta- 

 ceous; wings fusco-hyaline, the nervures and stigma black. 9- Length 4 mm. 



Head rugosely, but not closely punctured, thickly covered with glistening 

 white hair; the clypeus, a line in the centre of the face and the vertex behind 

 the ocelli smooth. Thorax coai'sely, irregularly rugosely punctured and reticu- 

 lated ; the greater part of the mesopleurse smooth and shining. Middle lobe of 

 mesonotum clearly separated, bounded by a keel, not reaching to the scutellar 

 depression, which is large, smooth and deep. Metanotum depressed at the base, 

 its centre with a deep, square area, bounded by stout keels; the lateral region is 

 divided into two by a transverse keel ; the parts between irregularly depressed ; 

 the apical slope is irregularly reticulated and margined above by a stout keel; 

 the base and aj)ex of the mesopleurae and the base of metapleurse with a row of 

 deep round foveae ; the mesosteruum closely reticulated. Abdomen closely,
