$ (J . Allied to and closely resembling the genus Chrysis ; 

 differs chiefly in the form and armature of the 3rd abdominal 

 segment. Head subtriangular, the cheeks below the eyes and the 

 clypeus, the maxilla and the labiuia rather long, longer than in 

 true Chrysis ; facial hollow short, not reaching quite up to the 

 base of the antennae. Thorax and abdomen with the sides parallel ; 

 wings proportionately longer than in Chrysis, the ueuration of 

 the fore wing similar, the radial cell always open, but never so 

 much as in Holopyya, and always for less than one-third of its pro- 

 bable length ; 3rd abdominal segment with a rounded transverse 

 subapical ridge in front of the anteapical series, the apical margin 

 serrate, beset ivith numerous small and large uneven teeth. In the 

 one species recorded so far from within our limits, the transverse 

 anteapical ridge is not so prominent as in the typical species.

. Metallic green with golden and blue tints on the vertex 

 and abdomen, scape of the antennae green, the flagelluni black, 

 the legs bluish green, the anterior and posterior femora at apex, 

 the anterior and intermediate tibiae in front, the posterior tibiae 

 entirely, and the whole of the tarsi rufo-testaceous ; head strongly 

 punctured, pilose, the pilosity white, thick in the facial hollow, 

 sparse and short elsewhere; the punctation in the facial hollow is 

 shallow, on the apex of the clypeus large and deep, forming irre- 

 gular foveae ; anterior ocellus surrounded at back and sides by a 

 smooth groove extending below it on to the front. Thorax more 

 or less closely coarsely punctured, the punctures coarser on the 

 scutellum and postscutellum than in front, the sides of the pro- 

 uoturn prominent anteriorly, the base impressed anteriorly in the 

 middle ; mesonotuin anteriorly depressed, closely, rather finely 

 punctured ; mesopleuraB grooved, rounded at the apex beneath ; 

 postscutellum gibbous, posteriorly superimposed on the median 

 segment, the posterior face of the latter with a medially carinate 

 area in the centre, the posterior lateral angles produced ; wings 

 fusco- violaceous, uervures black, tegulae large and punctured. 

 Abdomen : the apex of the 1st, the base and apex of the 2nd and 

 the base of the 3rd segment closely and minutely punctured, the 

 rest of the abdomen with larger, more distant punctures, the apical
