distinct keel runs clown from the front ocellus to the antennae, 

 and there is a more distinct stouter keel on either side whicli 

 commences lower down ; tlie central keel is thinner in the 

 middle. The eyes on the inner side are distinctly mar- 

 gined. Mandibles testaceous. Scape of antennaj dark green; 

 the flagellum black. Prothorax as long as the mesothorax, 

 distinctly narrowed at the base, and smooth and shining. 

 Mesonotum smooth and shining; the two furrows are wide 

 and deep and with stout transverse keels throughout, this 

 being also the case with the transverse keel at the apex. 

 The eight keels on the nietanotum are distinct and reach to 

 the apex, except the inner three, the outer two of which only 

 reach to the base of the apical third of the segment and 

 distinctly converge towards the apex. The segment, except 

 in the middle at the apex, is closely transversely striated. 

 The apical slope of the segment has a few oblique keels 

 above and some transverse ones in the middle ; the teeth on 

 the upper edges are stout. The propleuraj are furrowed on 

 the lower edge ; the mesopleurge distinctly punctured on the 

 basal half above ; below is a curved furrow which reaches 

 beyond the middle ; the upper part of the raetapleurai is 

 striated and is bordered below by a longitudinal keel ; the 

 apex, as is also the sternal region, is thickly covered with 

 white pubescence. Legs green ; the hinder tibia3 blue, the 

 tarsi darker in colour; the front tibige and tarsi dark testa- 

 ceous in front. Wings hyaline ; the radial cellule, the apex 

 of the first, the second and third cubital, and the discoidal 

 cellules smoky, with a faint violaceous tinge ; the three 

 transverse cubital nervures are distinct. Abdomen green, the 

 second segment blue ; it is about twice longer than wide and 

 is not much narrowed at the base. 



Comes near, judging from the imperfect description, to 

 A. insukiris^ Sm. The description is not sufficient for identi- 

 fication — e. g., no mention is made of there being any keels 

 on the front. In Kohl's monograph oi Ampul ex (Ann. Mus. 

 "Wien, viii. p. 495) there is a mistake in the copy of Smith's 

 description of A. insularis which may mislead: in the 

 fourth line of the description, for " mesothorax " read " meta- 

 thorax."

Black ; the abdomen, except the petiole, ferruginous ; the 

 wings fuscous violaceous, the a])ex of the fore wings darker, 

 the hinder pair lighter in tint; the third cubital cellule at the 

 top slightly shorter than the second, at tiie bottom distinctly 

 longer than it; the head and thorax thickly covered with
