110 HYMENOPTEKA FROM SARAWAK. 



median segment is closely and strongly punctured at the base ; 

 the apical furrow is wide, becomes gradually wider towards the 

 apex and is keeled down the middle ; its apical slope is oblique. 

 The second cubital cellule is narrowed at the top, the nervures 

 almost touching there ; both are straight and oblique ; the first 

 recurrent nervure is received distinctly behind the middle ; the 

 second close to the second transverse cubital, almost interstitial. 

 Legs black ; the fore femora are yellow at the apex ; the four hinder 

 are rufous below and probably in some examples above. Abdo- 

 men black ; the apices of the basal four segments yellow ; there 

 is an oval oblique mark on either side of the secoi.d segment at 

 the base. The petiole is nearly as long as the second segment ; 

 it is stout, with the basal third distinctly narrowed ; it is dis- 

 tinctly, but not very closely, punctured ; the second segment is 

 alutaceous. 



The generic location of this species is doubtful. It has 3- 

 and 6-jointed palpi as in Zethus, and it has further the head 

 largely developed behind the eyes as in that genus and thereb} T 

 differs from Rumenes. The petiole is shorter and stouter than it 

 is in the typical Zethus and also the second segment is not con- 

 tracted at the base into a neck. The form of the cubital 

 cellules is different from what they are in Eumenes and more 

 like what they are in Zethvs. It is not a typical Montezumia 

 either, although it has certainly some affinity to that genus, 

 which has five jointed maxillary palpi. I leave it, in the mean- 

 fcime,In Montezumm, which is,'strictly speaking, an American genus. 



Zethus varipunctatus, sp. nov. 



Black; the upper side of the mandibles and a large mark 

 on the apex of the clypeus, yellow ; the scape of the antennas, the 

 tegula? and the legs rufous; the hinder tibiae and tarsi blackish: 

 wings fuscous-violaceous towards the apex: the apex of the cly- 

 peus broadly rounded, not dentate o . 



Long : 17 mm. 



Hab. Kuching, Sarawak. 



Head thickly covered with short pale pubescence, rugosely 

 punctured, the punctures running into reticulations on the front. 

 Clypeus roundly convex; its greatest width greater than its 

 greatest length ; closely and distinctly punctured, but not so
