 publication. 



Mr. Duckett was a conscientious and unceasing worker, care- 

 ful and thorough in his investigations, although owing to the 

 nature of his work he had received but little recognition through 

 publication. His untimely death removes from the field of eco- 

 nomic entomology one of its most promising younger workers.

THE GENUS EPHIALTES FIRST PROPOSED BY SCHRANK. 



(HYM.). 



BY R. A. CTJSHMAN AND S. A. ROHWER, 

 Bureau of Entomology, Washington, D. C. 



The generic name Ephialtes was first proposed t in 1802 by 

 Schrank (Fauna Boica, vol. 2, pt. 3, p. 316) with Ichneumon 

 compunctor mentioned as an example and the only included 

 species. On an earlier page (p. 269) of the same work Schrank 

 listed Ichneumon compunctor, stating that he knew two forms 

 that belonged there, one with the body 6| lines and ovipositor 1\ 

 lines long and the other 13 lines long with the ovipositor \\ lines, 

 but otherwise alike. At this place he refers to an earlier work 

 by himself (Enum. Ins. Aust. 1781, p. 357), where he cites 

 Ichneumon compunctor Linnaeus, Faun. Suec. No. 1609 (evidently 

 a more detailed characterization of the species originally de- 

 scribed in Systema Naturae, tenth edition, page 564). It is 

 evident, then, that he meant the Linnaean species when he 

 used the name compunctor and this species must be the geno- 

 type. Ichneumon compunctor Linnaeus has not been definitely 

 recognized by subsequent authors, for references quoted under 

 that name by such authors as Schrank, Fabricus, and even Lin- 

 naeus himself refer to such figures as those of Degeer (Mem. 

 1'Hist. Ins., vol. 2, pt. 2, figs. 6-8), which is aPimpla in the sense 

 of authors ( = Pimplidea Viereck) and very similar if not iden- 

 tical with Pimpla instigator Fabricus; Schaffers (Icone. Ins., vol. 2, 

 pt. 1, PI. 110, fig. 3), which is obviously manifestator Linnaeus
