364 Professor E. B. Poulton on 



impression made by a study of 36 examples (pp. 332-835). 

 The conclusions expressed are confirmed and extended 

 by the consideration of 190 additional examples recorded 

 in the present Memoir. 



The analysis on pp. 359-362 makes evident the following 

 facts : — 



1. The great predominance among the prey of that 

 specially defended Order, the Hymenoptera, and 

 within its limits of the section including the 

 stinging insects. 



2. The fact that half the families of Coleoptera which 



contributed victims are looked upon as specially 

 protected : — The Galcrucidss, Melyridse, Ca7itJiaridie, 

 Ap7wdiidc'&, GdoniidfB, Lagriidm, and Cicindelid^ 

 (Trans. Ent. Soc. Lond. 1902, pp. 392-397).* 



3. Among Rhopalocera the inclusion of Danaine, 

 Acreeine and Pierine (including Mylothris) victims : 

 among Heterocera of a Lymantrid victim. 



4. The existence, although in small numbers, of 



Hemipterous prey. 



Conclusions as to the habits of the species and 

 genera of asilidie recorded in this memoir. 



I. Dasypogonin^. 



Diodria (Nos. 1 to 10). — It is not necessary to present 

 any further analysis of the tabulated record in the case of 

 this genus. It is obvious that Iclincumonidm form the 

 chief prey of these slender Ichneumon-like Asilids (Trans. 

 Ent. Soc. Lond. 1902, p. 336). In 4 out of 10 examples 

 tlie prey belonged to this group ; while in the whole of 

 the Asilidm other than Diodria, only 6 instances of 

 Ichneumonid prey are tabulated. Hence we are led to 

 believe that the species of Diodria are the chief Asilid 



* Tliis list of specially protected Coleopterous victims will 

 undoubtedly be extended. Indeed some evidence is already in 

 existence as recorded in the following statement by Kirby and 

 Spence (Fifth edn. 1828, vol. i, p. 396), which I owe, together with 

 the quotations on pp. 365 and 388, to Mr. A. H. Hamm, Assistant 

 in the Hope Depai-tment : — " De Geer has seen an Asilus pierce . . . 

 the elytra of a lady -bird ; and I have myself caught them with not 

 only an Elater and weevil, Init even a Hister in their mouths."
