simus, Smith. XIT. — Ceropales, Latreille. I'yiie C. maculata, Fabr. 

 XIII. — Pompiius,Ydhx\z\v\?,. Types P. viaticus, ursus, Fabr., = Aporus, 

 Spin.; Episyron, Schiodte ; Anoplius, Lepel; Evagetes, Lepel.; Salius, 

 Dahlb.; Homonotus, Dahlb., and Ferreola, Smith. 



Dr. Kohl, however, recognized i8 minor groups, briefly defined, but 

 without specifying, in most cases, the species belonging in them. His 

 groups he has arranged thus: Gr. (r), Fofnpilus, Thoms.; Gr. (2), 

 Aporus ; Gr. (3), no name ; Gr. (4), no name; Gr. (5), Aporus ; Gr. (6), 

 no name ; Gr. (7), no name ; Gr. (8), Aporus ; Gr. (9), no name ; Gr. 

 (lo), Aporus : Gr. (i i), Aporus ; Gr. (12), Episyron, Schiodte ; Gr. (13), 

 Pompilus 6-maculatus, Spin., —venustus, Wesm., =fraterculus, Costa; 

 Gr. (14), Aporus; Gr. (15), Homonotus, Dahlb., p. 35; Sa/ius 

 sa?iguinolentus, Dahlb., p. 34; Gr. (16), Ferreola, Smith; Gr. (17), 

 Ferreola, Smith; Gr. (18), Pedinaspis, Kohl. Type P. operculatus, 

 Klug. 



XlV.^Planiceps, Latreille. Type Pompilus planiceps, Latr. XV. — 

 Epipompilus, Kohl, n. g. Type E. maximiliaui, Kohl. 



This arrangement of Dr. Kohl's is in no sense a natural one. He 

 has " lumped " many good genera (or natural groups) and interpolated, or 

 at least brought into juxtaposition, genera or groups that are tuidely 

 separated, and, again, widely separated others that are closely allied. I 

 hope to bring this out clearly in my tables later on, when I shall call 

 more special attention to some of these unnatural groupings. 



Dr. Paolo Magretti, in this same year, 1884, in the Ann. Mus. Civ. 

 Geneva, Vol. XXL, p. 44, established the genus Paracyphonyx, an 

 interesting new genus allied to Cyphonyx. 



In 1887, Achilles Costa, in his Prosp. Imen. Ital., II., established 

 three new genera, recorded above. 



Genl. O. Radoszkowski, in the Bull, de la Soc. Imp. des Nat. de 

 Moscow, (2) II., 1888, in his paper entitled "Revision des armures 

 copulatrices des males de famille Pompilidas," points out and figures 

 excellent characters in the male genital organs of several genera. The 

 difterence in the male copulatory organ in Ceropales was so great that he 

 remarks : " L'armure copulatrice du genre Ceropales n'a rien de commun 

 avec la famille Pompilidjy, except la presence de palpes genital." 



Genl. Radoszkowski subsequently makes Ceropales the type of a 

 distinct family, the Ceropalidce. The group is a natural one, and is here 

 treated as a subfamilv.
