16th are white^ dusky beneath, with the apex incurved ; scutellum white or 

 yellow ; of the male with sometimes only a small spot; abdomen of the male 

 rather narrower than the thorax, with the 7th segment entirely white ; of 

 the female as broad as the thorax, with the 2nd and 3rd segments finely 

 punctured, and frequently slightly edged with reddish; the 6th with the 

 margin more or less broadly white, and the 7th with the back entirely of 

 that colour; ovipositor slightly exserted ; legs red; coxse and trochanters 

 black ; posterior trochanters often reddish at the tip ; tibite and tarsi black 

 at the apex, and the tips of the femora sometimes slightly fuscescent; wings 

 smoky-hyaline ; stigma, costa, and scales black or pitchy, rarely pale ; 

 cellule 5-angular, 



The femora are sometimes black, and the insect varies extremely : — I suspect 

 that Gravenhorst has united more than 2 species, judging from the great 

 discrepancy observable in the specimens in my collection. 

 Not common ; found in June and July, within the metropohtan 



district ; also in Salop and in Devonshire.
