is minutely serrate. The ovipositor is short, stout, obliquely narrowed at the 

 apex. 



Etro:cys xanthopus, sp. nov. 



Green variegated with brassy and blue tints, the metanotum indigo blue ; 

 the abdomen of a brighter colour than the thorax ; the antennal scape dark 

 fulvous ; the flagellum fuscous ; legs pale straw yellow ; the anterior coxa?, 

 except at the apex, dark golden ; wings clear hyaline, iridescent, the nervures 

 pale testaceous. 9 . 



Length 3 mm. 



Quetta. June. 



Head closely, distinctly punctured, the front and vertex slightly more 

 strongly than the face ; the clypeus indistinctly separated from the face, 

 closely, longitudinally, slightly obliquely striated. Palpi yellow. Pro- and 

 mesothorax with scutellum punctured like the head ; the metanotum is much 

 more obscurely punctured ; there is a keel down the middle ; at the base 

 laterally is a distinct fovea, the obscure punctuation is intermixed with fine 

 stria?. On the centre of the metapleura? is a deep, wide longitudinal furrow, 

 which is narrowed at the base. Abdomen as long as the head and thorax 

 united, smooth and shining, gradually narrowed to a fine point at the apex. 



The antennas are more slender and the parapsidal furrows less distinct than 

 they are in the British species of Etroxys. I have used the original spelling 

 of this word as used by Ashmead in his " Classification of the Chalcid Flies." 

 It has been spelled Aetroxys and Hetroxys. 



Etroxys ? marghiicollis, sp. nov. 



Dark coppery green, the abdomen of a brighter green colour, largely tinged 

 with coppery patches ; the antennal scape and base of mandibles rufo- 

 testaceous ; the flagellum fusco-testaceous, darker above ; the legs dark green,, 

 with coppery tints ; the apex of femora, the tibia? and tarsi pale straw 

 yellow ; wings clear hyaline, the nervures pale yellow. $ . 



Length 3 mm. 



Quetta. June. 



Head closely, finely, distinctly, but not deeply punctured ; the clypeus not 

 separated from the face, closely, regularly, distinctly striated. Thorax punc- 

 tured like the head, the punctures running into reticulations, especially on the 

 mesonotum ; the sides of the metanotum are smooth, shining and bright green ; 

 its centre is somewhat more strongly punctured than the scutellum. Pleura? 

 darker coloured than the scutellum ; the apex of the pro- and meso- smooth 

 and shining ; the rest closely punctured-reticulated. Abdomen not quite so 

 long as the head and thorax united ,• the apical half is gradually narrowed 

 towards the apex, and is covered with a white pubescence. 



Apart from the difference in the colouration of the legs this species may be 



known from E, xanthopus by the shorter and broader abdomen and by the 



much more strongly and regularly punctured-reticulated metanotum. The 



abdomen is shorter and broader than it is in typical Etroxys ; and it may not
