Note that Dahlbom says distinctly " thorax antice " and not the 

 whole of the thorax ** fulva." The species I take to be flava agrees 

 with the" description in this and also with Fabricius' and Lepelletier's 

 descriptions, even to there being varieties which have the base of the 

 1st and 2nd segments of the abdomen stained with testaceous-yellow ; 

 but then the whole of the series of over twenty specimens I have 

 have the three apical segments and not the anus alone ferruginous. 



Dahlbom again — and here comes the confusion at page 123 of the 

 work quoted above — describes an insect under the name Hemipepsis 

 flava thus : — ^' 26. Genus Hemipepsis, Dlbm. "(l)/aua, $, 9 ; media 

 (subsemi-pollicaris et ultra) atra, oculis brunneis ; capite cum antennis- 

 pro- et mesonotis, genubus, tibiis, tarsis alesque subaureo-fulvis, his 

 apiee mgro-violascenti-fumatis, ano nonnunquam brunescente ; " and 

 the gives as synonyms ^^Sphexflava^ Fabr. E. S. 2, 217, 80 ; Pompilus 

 JlavuSy Fabr. Piez. 197, 52 : anne Pompilus luteipennis^ Fabr. Piez. 

 198, 54 ; and Pompilus fulvipennis^ Fabr. Piez. 198, 57, huic 

 referendi." 



Now as Dahlbom instituted the genus Hemipepsis and considered 

 it differed from Priocnemisy and as he specially notes ( introduction to 

 " Hymenoptera Europea," vol. i, p. xx referred to above ) that his 

 Priocnemis flavus = Pompilus flavus^ Fabr., it seems to me clear that 

 there is some mistake in his putting the synonyme above- quoted under 

 Hemipepsis /lava, which insect, in my opinion, is quite distinct from 

 Pompilus flavris of Fabricius. I am the more inclined to think so, 

 because further on at p. 462 in the *' Tabula Examinationis Synoptica 

 Specierum Pompilidaram," Dahlbom allows luteipennis and 

 fulvipennis of Fabricius to stand as distinct, and gives Hemipepsis 

 fiava apparently as his own species. . I note later on what I take 

 this insect, Hemipepsis fiava^ Dahlbom, to be.
