 PL XV, fig. 3. 



Cynips pedestris, Curt., B. E., 320, No. 32. 

 Xystus cursor, Htg., Germ. Zeit., ii, 200. 

 Allotria cursor, Gir., Yerh. z.-b. Ges. Wien, x, 131. 

 Allotria pedestris, Cam., Fauna, 88, 27 



Black ; the head and thorax sometimes piceous ; the antennae fuscous, 

 pallid testaceous at the base ; the legs obscure testaceous, obscured 

 more or less with fuscous. Antennae in $ thickened towards the apex, 

 the third joint about one fourth longer than the succeeding ; in the 

 longer than the body. Wings abbreviated, seldom extending much 

 beyond the base of the abdomen. 



Length 1 1 mm. 



Not rare. Mull, Clydesdale, New Galloway. 

 Germany, Austria. 



II. RADIAL CELLULE OPEN (=Attoxysta SiudPezophycta). 



1. Wings fully developed. 



Differs simply from Allotria in having an open 

 radial cellule. Pezophycta only differs in having the 

 wings more or less abbreviated. The radial cellule is 

 frequently distinct and is certainly open on the fore 

 margin, and the radial nervure terminates before 

 reaching the costa. Dylita, Foerster (1. c., p. 340), is 

 distinguished from Alloxysta merely by the last-men- 

 tioned peculiarity ; so that if it is to be regarded as a 

 distinct genus, Pezophycta should be placed in it, 

 rather than in Alloxysta.
