submarginal cells, basal vein interstitial, cubital vein of hind 

 wings originating distinctly beyond apex of submedian cell, legs 

 as usual (fore femora not swollen), tarsal claws strongly uniden- 

 tate within near base, no tarsal comb, elongate pronotum and 

 abdomen compressed apically. 



That they are distinct from Parapompilus Smith, we see in the 

 ample wings and distinctly unidentate claws, and that the second 

 ventral segment of abdomen is not transversely impressed. 



That in the dentate claws they differ from Kohl's Group 17 

 of Potnpilus (= Ferreola) and in the non-interstitial cubital vein 

 of hind wings and laterally compressed abdomen from Kohl's 

 Group 16 (= Ferreola) ; and in the fact of the middle segment 

 being not emarginate excludes them from Kohl's Group 15 

 (^■= Hominotus Dhlb. They differ also from Hominohis by their 

 dentate claws. With Kohl's Group 18 (= Pedinaspis) they 

 agree well. 



From Planiceps Latr. , they differ in the number of marginal 

 cells, non-enlarged fore femora and dentate claws, the ordinary 

 femora and number of submarginals; they are also differentiated 

 from Aporus. 



The conclusions we reach by these facts are : (i) The species 

 in question do not belong to Parapornpi/us Smith (= Microp- 

 teryx Lep.*); (2) they cannot be referred to Ferreola, Homi- 

 notus or Planiceps ; (3) that they are related to Kohl's Groups 

 15, 16, 17 and 18 (^Hominotus, Ferreola and Pedinaspis). and as 

 the description of Group 15 fits them fairly well, Parapompilus 

 Cresson, must henceforth stand as Pompihis (Gr. Pedinaspis 

 Kohl), to which belong the following American species : l(Bvi- 

 frons, vicinus, planatus, texanus, savgicineus, maricB and legatus. 



Neither Parapompilus or Pompihis (Gr. Ferreola) occur as yet 

 in the United States. 



In a later paper,t Herr Kohl has reached the same conclusion 

 regarding Parapompilus Cresson, and unites as one Group 

 Pedinaspis, Parapompilus Cress. , and Planiceps. It is preferable, 

 in my opinion, to retain Planiceps as at least a Group of Pompilus. 



* Kohl points out that the name was used for a genus in Lepidoptera prior to its 

 adoption by Lepelitier de St. Fargeau , consequently Smith's name must stand,
