Ahdomen slender, a little longer tlian the head, thorax, and 

 median segment combined ; the first segment longer than 

 the second, the basal third, forming a narrow petiole, the 

 apical two-thirds swollen ; segments 2-6 slightly constricted 

 at the base ; the apical segment with the emargination 

 broader at the apex than deep, the lateral processes rounded 

 at the apex, the spine o£ the hypopygium long and sharply 

 recurved. Head and thorax closely punctured and rather 

 thickly clothed with long white pubescence, abdomen more 

 sparsely and finely punctured. Radial cell rounded at the 

 apex, less than twice as long as the greatest breadth, ex- 

 tending on the costa for less than two-thirds of the distance 

 from the apex of the stigma to the apex of the wing, second 

 abscissa of the radius as long as the third, the third cubital 

 cell only about one quarter longer on the cubitus than on 

 radius ; first recurrent nervure received beyond the middle 

 of the second cubital cell, second before the middle of the 

 third cubital cell, the neuration not continued beyond the 

 cubital and discoidal cells. 



Black ; the mandibles, tegulse, a transverse spot in the 

 middle and one on each side of dorsal segments 2-6 pale 

 yellow ; tibiae and tarsi yellow marked with black. Wings 

 hyaline, nervures black.

This species is very distinct in neuration from typical 

 Myzine, more nearly approaching some of the species of 

 Isivara, though in other respects it does not resemble that 

 genus. It can only be placed in Myzine provisionally.

5 . Nigra, mandibulis basi fusco-ferrugiueis ; pygidio rufo, striate :

 Long. 10 mm. 



? . Clypeus sparsely punctured, rounded at the apex. Head 

 and thorax closely and rather deeply punctured, more finely 

 and sparsely round the ocelli and on the seutellum, the 

 median segment finely punctured, with a median groove. 

 Abdomen finely and shallowly punctured, the ventral surface 

 shining and with very scattered punctures ; pygidium 

 closely longitudinally striated, the strise not reaching the 

 broadly rounded apex. First abscissa of the radius 

 longer than the third, which is a little longer than the 

 second. First recurrent nervure received at the middle of 

 the second cubital cell, second just before the middle of the
