PAMPHILIUS PALLIPES. 107 



indistinct central one, a more distinct transverse one, in front of the 

 ocelli. 



The $ has only the outer mark on the vertex, none on the thorax ; 

 the belly has more yellow, the anal appendages fulvous, and, if any- 

 thing, the head is more strongly punctured. Apical segment above 

 deeply, somewhat triangularly, incised, the white membranous part 

 depressed, slightly incised at apex. Stigma fuscous. 



Length 5 lines. 



The strongly punctured, opaque rugose front dis- 

 tinguishes readily this species. In addition the fact 

 of their being no white or yellow marks over the 

 antennae, and the abdomen being only obscure fulvous 

 in the middle, serves further to distinguish it. The 

 black clypeus and the fuscous border of cingulatus 

 enables that species to be known from it. 



Rare. Pitlochry (Alfred Beaumont) ; near Hastings 

 (Bloomfield). 



Continental distribution : Sweden, Germany. 



Note.Kirby (List of Hym.i,338,33) records P. lati- 

 frons, Y3\\. 9 = maculosus, Zad., as British; but the 

 specimen he refers to latifrons is not that species, nor 

 apparently is it any I have described. It is black ; a 

 line along the vertical sutures, one running to the eyes ; 

 two marks over the antennse, an oblique one on either 

 side of this ; a mark on clypeus ; one on mesonotum, the 

 scutellum, tegulse and legs, clear yellow. Abdomen 

 black, yellow spotted along the edges ; the fourth seg- 

 ment, two marks on fifth and anus, fulvous. Antennae 

 fuscous, the base of flagellum fulvous, the scape 

 yellow ; the third joint more than twice the length of 

 the fourth. Wings hyaline ; stigma pale yellow. 

 Vertex impunctate ; clypeus punctured, keeled in the 

 middle ; mesonotum almost impunctate. 



The species I have been unable to satisfactorily 

 determine. 



P. latifrons 9 it may be added, differs from P. pallipes 

 and P. depressus in the latter having the third joint 

 more than treble the length of the fourth ; while it has 

 it barely double the length.
