Predaceous Insects and their Prey. 377 



a mixed diet. Six examples out of ten belong to this 

 Order (1 Tipulid, 1 Empid, 1 Conopid, 1 Syrphid, 1 

 Tachinid, 1 uncertain), the other victims being an Aphodiid 

 and a Curculionid beetle, a Cimicid bug, and a Hepialid 

 moth.* A single example of another species of the genus 

 Neoitamus was carrying a beetle. 



Epitri])tus (Nos. 217-219). — The three victims (2 small 

 moths, and 1 Muscid) recorded for two species are quite 

 insufficient as evidence for the existence of any prefer- 

 ence ; but comparing the number of the moths with that 

 shown in the complete analysis (p. 361), it becomes not 

 improbable that future observation will demonstrate 

 some preference for this diet. 



The remaining records (Nos. 220-226), dealing with 

 undetermined Asilidm, cannot of course be considered in 

 this section. 



Mimicry in Asilid^e recorded with Prey. 



The statements on mimicry and its varying relationship 

 to the prey attacked by the mimetic species, scattered 

 through the preceding pages, and already published (Trans. 

 Ent. Soc. Lond. 1904, pp. 661-665) may now be gathered 

 together into a tabular statement. It is important to 

 remember that most of the species are only provisionally 

 included in their respective groups on account of the 

 insufficiency of the records. It is hoped however that the 

 publication of a tabulated scheme, given on page 378, will 

 stimulate observation and the preservation of material, 

 so that at no distant date the means for a more com- 

 prehensive and more trustworthy classification may be 

 gained. 



* Mr. G. H. Verrall's observation recorded in footnote * on p. 356, 

 proves that moths are sometimes attacked on a large scale by 

 this species.
