A SYNOPSIS OF BEITISH PROCTOTRYPIMI 

 (OXYURA). 



By Claude Morley, F.E.S., F.Z.S., etc. 



(Continued from p. 3.) 



PROCTOTRYPES, Latreille. 



Proctotrupes, Latr., Prec. Car. Gen. Ins., 1796, p. 108 ; 

 Serphus, Schr., Schrift. Berl. Ges., i, 1780, p. 307 {nee. Syrphus, 

 Fab., 1775). 



This genus as restricted nowadays occurs in Africa, Australia, 

 Chili, and both North and Central America ; I have seen none 

 from India. It has been divided into three subgenera by 

 Kieffer, who considers them probably worthy of generic rank ; I 

 do not. The species are very distinct inter se, and easy of 

 determination ; in fact, until the structure of the claws be 

 examined they are less different from those of Exallonyx than 

 from each other. They appear to occur ubiquitously and with no 

 reference respecting situation ; I haver never, or extremely rarely, 

 found them upon flowers, but usually by beating boughs and 

 sweeping rank herbage ; though most frequently they are 

 attracted by honey-dew upon the leaves of oaks, and particularly 

 of limes.
