Hynienoptera Oricntnlis. 95 



behind the eyes, which are large and almost parallel ; 

 covered with a short sparse white down, and sparsely with 

 longish black hairs ; front and vertex obliquely aciculated, 

 the former only excavated immediately above the antenn.'E 

 and without a longitudinal furrow ; clypeus sparsely punc- 

 tured ; its apex almost transverse in the middle, the sides 

 somewhat oblique ; the centre slightly incised ; mandibles 

 obscure reddish towards the centre, the outer side broadly 

 at the base striolated. Thorax covered with a fuscous 

 pubescence ; the tubercles and a spot on either side of the 

 median segment silvery. Pro- and mesonotum strongly 

 transversely striolated, the striolations rather widely sepa- 

 rated ; propleurae obliquely striolated ; meso- and meta- 

 pleunie longitudinally rugosely punctured ; metanotum 

 transversely rugosely punctured ; scutellum longitudinally 

 striolated ; mesonotum with a shallow channel in the centre ; 

 metanotum not elevated in the centre ; a shallow indistinct 

 furrow below the spiracles. Petiole longish ; the second 

 joint usually blackish at the base. Coxae covered with a 

 dense moderately long silvery pile ; the trochanters, tibiae 

 and tarsi, with a shorter and thinner one ; hind coxae 

 coarsely punctured ; tarsal spines black ; fore calcaria red ; 

 hinder black, reddish at base ; apex of tarsi black. Second 

 cubital cellule at top a little wider or a little narrower than 

 the space bounded by the recurrent nervures ; third cubital 

 cellule a little wider at top than at bottom, the second 

 transverse cubital nervure bent outwardly at the bottom ; 

 tegulae blackish to piceous. 



A. humbertiaiia, Saus. from Java, seems to be the nearest 

 ally of this species, but it has the metanotum "postice 

 oblique in V-formam elevato-strigato," and the trochanters 

 are not black. A. basalis is also nearly related to it, but is 

 smaller (15-17 mm.), has the face silvery pilose, densely 

 so on the clypeus ; the head smooth, impunctate, wings 

 hyaline, &c. Barrackpore ; Allahabad, N. W. Province.
