THE THIRD GENUS OF THE FAMILY EL ASM I D^ 



(HYMENOPTERA). 



BY A. A. GIRAULT, NELSON, N. Q., AUSTRALIA. 



The following genus and species was found just too late to 

 be included within the supplement to the Elasmidae (memoirs 

 Queensland Museum, II., 1913). It was first mistaken for 

 Euryischia Howard, the species being characteristic for that genus 

 because of its slenderness and pale legs. The genus differs from 

 Euryischia in bearing complete parapsidal furrows, a slender, 

 conical abdomen, and in lacking the prominent projection caudad 

 of the submarginal vein near its apex, moreover the coxae are 

 not compressed but cylindrical. Otherwise, it is very similar to 

 Howard's genus in all details and in general appearance. 



Family Elasmidae. 



Eur3'ischomyia, new genus. 



Type — The following species: 



Euryischomyia washingtoni, new species. 



Female — Length, 1.00 mm. Slender, the abdomen conic-ovate. 



Jet black and like the species of Euryischia, but the legs, 

 except hind coxae and femora, lemon yellow, also the tegulae and 

 the fore wings bear a clearly delimited, broad, jet black band 

 across them under the marginal and most of postmarginal veins, 

 the distal margin just reaching apex of stigmal vein, the proximal 

 margin nearly straight; wings otherwise hyaline. Scutum with 

 hardly more setae than the scutellum which is nearly naked, the 

 few sparse setae whitish. Thorax finely scaly. Mandibles 

 bidentate, the second tooth broadly truncate. Two ring-joints, 

 the three funicle joints subquadrate, the third wider than long. 

 Bristles under submarginal veins short, not more than two. 

 Submarginal vein entire and continuous. Hind coxae greatly 

 enlarged, cylindrical, ovate; the hind femora compressed. Tarsi 

 5-jointed. 



Male — The same but the abdomen shorter, more obtuse at 

 apex. 



Described from one male, two female specimens captured 



August, 1914.
