mesothorax having much fewer punctures (there arer 

 only some fifteen on the middle lobe of the meso- 

 notum) ; in the furrow in the centre of the lateral 

 lobes of mesonotum being almost obsolete ; in the^ 

 reticulation on the metathorax being stronger ; in 

 the petiole being stouter, more produced at the apex 

 beneath, and furrowed laterally ; in the praebrachial 

 transverse nervure being received nearer the base of 

 the stigma, so that the part of the first cubital' 

 cellule bounded by it is longer than that bounded 

 by the nervure and the apex of the stigma, the 

 opX30site being the case with E. laevigata; the ner-^ 

 vure itself being also distinctly curved; the first 

 cubital cellule is shorter and wider, being nearly as- 

 long as broad, while in laevigata it is longer than 

 broad; the base on the lower side of the cellule 

 in laevigata, too, forming a sharp angle at its juncture 

 with the recurrent nervure, and not, as in the present 

 species, a curve ; the recurrent nervure is distinctly 

 curved, is not interstitial, but is joined to the cubitus 

 by a short pedicel. The mandibles have one large 

 apical tooth. 

 Hab. Tahiti, Society Islands. 



The following species of Evania from Ceylon 

 (where it was taken by Mr. George Lewis) appears 

 to me to be undescribed : 



EVANIA CARINIFRONS, n.s. 



Black; densely covered with long greyish pubes- 

 cence ; wings hyaline, with a slight trace of a fuscous 

 tinge. Antennae stout, longer than the body, the 

 scajDe bearing a silvery pile. Vertex covered with 

 large punctures ; front densely covered with silvery 

 pile, irregularly longitudinally striated ; it is scarcely 

 excavated above the antennae. Face strongly,, 

 acutely striated, the striations converging towards 

 the centre; a stout keel down the centre, issuing 

 from between the antennae, and joined a little from 

 its origin by a short keel from each antenna. 

 Mandibles shining and bearing three teeth, in addition
