THE CANADIA.N ENTOMOLOGIST. 151 



Frederick Smith, in his Catalogue of the Hymenoptera in the British 

 Museum, Vol. III., 1S55, ignores these tribes, but correctly treats the 

 family as distinct from the Sphecidfe. He has recognized 13 distinct 

 genera, arranged in the following sequence: Pompiliis, Maurilltis n. g., 

 Salius, Notocyphns n. g., Ctenocenis ( = Claveiia, Lucas), Planiceps, 

 Aporus, Parapompihis n. n. ; for Micropteryx, Lepel. ; Ceropa/es, 

 Mdcromeris, Mygfiimia and Pepsis. 



Under the genus Pompiius, .Smith incorrectly includes as synonyms 

 Pi-iociie/iiis, Age/iia, Episyron, Calicurgus and Anopilus. Maurillns, 

 Smith, placed by Dalla Torre in his recent catalogue as a synonym of 

 Pompilus, does not belong to the family, but is evidently a good genus 

 in the family Cosilidce, to which family also belong Dicrogenium, Stadel- 

 mann, described as a Bethylid, and Fedtschenkia, Saussure, at present 

 placed with the Miitillidce. 



The next paper of any great importance on the group, is by Dr. 

 Franz Frederick Kohl, entitled " Die Gattungen der Pompiliden," 

 published in the Verhanlungen Zoolog-botanischen Gesellschaft in Wien, 

 1884, pp. 33-58. 



In this important contribution Dr. Kohl gives a table of genera and 

 has recognized as valid 15 genera and several subgenera and groups, 

 arranged as follows. 



I. — Macrofneris, Lepeletier. Type M. splendida, Lepel. II. — 

 Age/iia, Schiodte. Types A. variegata, L., and A. bifasciata, Fabr. III. — 

 Pseudagefiia, Kohl, n. g. Type Agenia carbonaria, Scop. IV. — Sa/ius, 

 Fabricius. Types S. bicolor and S. punctatus, Fabr., = Priocnemis, 

 Schiodte ; Hemipepsis, Dahlb.; Homonotus, Dahlb.; Etitypus^ Dahlb.; 

 Pallosoma, Lepel.; Mygnimia, Smith. 



Four groups of subgenera are indicated : Gr. (i) Cyphonyx, (2) 

 Priocnemis, (3) Hemipepsis, and (4) not named, with ffe??iipepsis heros, 

 Guerin, as type. V. — Caliatrgus, Lepeletier. Type C. fasciatellus, 

 Lepel. VI. — Pepsis, Fabricius. Types P. ruficornis, dimidiata, 

 amethystina, coerulea, stellata, elevata, and grossa, Fabr. VII. — 

 Spkictostethtfs, Kohl, n. g. Type Pompilus Gravesii, Hal., = Agenia 

 speciosa. Spin. VIII. — Hoploneura, Kohl, n. g. Type H. apogona, 

 Kohl. This genus was subsequently changed to Hoploneurion. IX. — 

 Parapompilus, Smith, = Micropteryx, Lepel. Type P. (Micropteryx) 

 brevipennis, Lepel. X. — Clavelia, Lucas, = Ctenocerus, Dahlb. Type 

 C. pompiliformis, Lucas. XL — Notocyphus, Smith. Type N. Ifevis-
