Hymenoptera Orient alls. 259 



pleurae aciculate, the base with a few stout striae. Petiole 

 wider than long, bulging out in the centre ; sparsely and 

 finely punctured ; the fifth segment also sparsely punctured ; 

 the others obscurely aciculate. Pygidial area large, rounded 

 at apex, not narrowed at the base ; transversly striolated ; 

 incision in hypopygium not reaching to the middle, a little 

 longer than wide, rounded at the base. Hinder tibiae very 

 stoutly and closely spined. Second cubital cellule longer 

 than broad, rounded above, above shortly pedunculated ; 

 the recurrent nervure received shortly before the middle. 



The $ has the face from the top of the antennal ridge 

 entirely yellow ; the clypeus flattish ; the apex rounded, 

 almost transverse ; the lateral plates incised ; there is a 

 small yellow mark below the tubercles ; there are two large 

 yellow marks on the median segments ; the fourth segment 

 is almost entirely yellow ; the fifth has a narrow yellow 

 border on the apex, the sixth is almost entirely yellow ; the 

 sides of the apical segment are yellow : the legs are clear 

 yellow ; the hinder femora are marked with black, the hind 

 tibiae are broadly black at the apex and the hind tarsi are 

 fuscous ; otherwise coloured as in ?. Pygidial area with 

 large punctures, the apex almost transverse. Length 1 1 mm. 



Easily recognised by the smooth impunctate abdomen. 



Cerceris pictiventris, Dbm. 



This species is no doubt identical with C. novarce, at 

 least that species agrees with the rather laconic description 

 given by Dahlbom — Abdomen nigrum, flavo-fulvo — aut 

 albo-fasciatum . . . petiolus nigrum . . . segmenta 

 ventralia plurima flavo-fasciata aut maculata — Corpus sub- 

 parvum . . . abdomen fasciis citrinis pleurumque 3 raro 

 pluribus ; $ segmento ventrali valvutae proximo ad marginem 

 apicalem intergerrimo.
