the apex ; the basal parts more oblique and straighter than 

 the apical, the part enclosed by them strongly transversely 

 striated, this being also the case, but less strongly, with the 

 outer side ; the apex in the middle is smooth and has on 

 either side at the base a round, deep fovea ; at the apex, in 

 the centre, the keels are raised, leaving a rounded depression 

 between them. The apex of the segment is semi-per- 

 pendicular, stoutly transversely striated, and tliickly covered 

 with long black hair. Pleurae impunctate, except the apex 

 of the metapleurge, which is stoutly obliquely striated. Meso- 

 sternum smooth, thickly haired ; the middle depressed and 

 with a black keel in the depression ; in the centre of the 

 lateral part is a shorter black keel. Wings fuscous violaceous, 

 darker in the radial and cubital cellules. Abdomen blue ; 

 the narrow basal part of the petiole short, becoming gradually 

 wider towards the apex ; the transverse furrow at the base of 

 the second segment is deep ; the second segment is as long 

 as the succeeding segments united. 



The upper nervure in the apex of the radial cellule is 

 roundly curved ; the appendicular cellule is closed ; the part 

 of the radius bounding the second cubital cellule is nearly as 

 long as that bounding the first ; before the first recurrent 

 nervure is a faint nervure, perhaps representing the transverse 

 cubital. The claws are long, sharp, and with a sharp tooth 

 near the base.

Antennae stout, about as long as the head and thorax 

 united ; the third and fourth joints equal in length. Head 

 bluish green, the face with brassy tints, the vertex to the 

 front ocellus purple; the vertex wide at the top, the eyes 

 there separated by the length of the basal three joints of the 

 antennae united ; the eyes almost parallel. Behind, the head 

 is largely developed and roundly narrowed ; the punctui'es on 

 the vertex are distinctly separated ; the hinder part of the 

 vertex impunctate, except near the margin, where it is finely 

 and closely punctured; the front is coarsely and irregularly 

 reticulated. Clypeus projecting in the centre, which is flat, 

 rounded at the base, gradually narrowed to near the apex, 

 which becomes more widely depressed in the middle and at
