joint not quite twice the length of the second, which is slightly 

 longer than hroad ; the third is as long as the basal two united and 

 shorter than the fourth. Hind ocelli separated from each other by 

 less than double the distance they are from the eyes ; the hinder are 

 placed in front of the hind edge of the eyes, not beyond them as in 

 G. (lunhrodijcnsc. Malar space less than the length of the second 

 antennal joint. Base of middle lobe of mesonotum rugose, the 

 middle with clearly separated punctures, the apex more sparsely 

 punctured. Scutellum with some large punctures. Metanotum 

 aciculated, with scattered punctures, the middle bounded by curved 

 furrows ; the sides thickly covered with white pubescence. Pro- 

 pleurae strongly aciculated. Mesopleurte irregularly reticulated, 

 with a large, triangular, strongly aciculated space at the base, the 

 wide lower end of which is bounded by a furrow. Metapleuras 

 more regularly reticulated. Apical slope of metanotum irregularly 

 transversely striated, with a smooth line down the middle. Hind 

 coxae four times longer than wide ; the upper side strongly striated, 

 more strongly in the centre than at the base or apex. Anterior 

 discoidal cellule small, narrow, slightly narrowed towards the apex ; 

 the apical cellule of the same width. Pronotum short, as long as 

 wide, as seen from above. Hind metatarsus shorter than the other 

 joints united. Apex of sheath of ovipositor cream-coloured.

First abscissa of radii;s veiy short, but distinct, issuing from the 

 centre of the stigma, which is linear, moderately broad. First 

 abscissa of cubitus received shortly below the first transverse 

 cubital nervure, united to the top of the recurrent nervure. Trans- 

 verse median nervure received distinctly beyond the transverse basal. 

 Eadial cellule long, wide, reaching to the apex of the wing ; the 

 radius and cubitus in the hind wing short, indicated only on the 

 basal half ; at the base in front there is one large closed cellule, 

 bounded anteriorly by a stout nervure (the praebrachial ?) ; at its 

 base behind is a short cellule. Parapsidal furrows distinct. The 

 middle of the base of metanotum bears a longitudinal keel, which 

 curves round to the sides, forming two large smooth areas, bordering 

 the top of the apical slope, which bears some longitudinal keels. 

 Abdomen smooth, the ovipositor slightly longer than it. 



Belongs to the Tribe AUoeini.
