14 Mr. Ernest A. Elliott and Mr. Claude Morley on the 
frequent our dwellings, to deposit their eggs in the larve 
of Dermestidxe, Anthreni, Tinex, and other domestic insects.” 
These vague and general statements are dangerous, since 
the above is undoubtedly the foundation of Taschenberg’s 
apparently established fact (Zeits. Ges. Nat. 1865, p. 180) 
under H. arcator, Panz.: “Wurde erzogen... aus Derm- 
estes—Anthrenus—und Tineen—Larven”; and Ratzeburg 
(Ichn. d. Forst. i, 151) takes the same view. Cf., however, 
Morley, Ichn. Brit. 11, 133. 
27. Sinodendron cylindricum, Linn. 
Keys first took localised British specimens of Hister- 
omerus mystacinus, Wesm., on 14th August, 1901, from 
the burrows of this beetle ; and ten days later Bignell and 
he discovered three of these coleopterous larvae each sur- 
rounded by about a dozen apparently full-fed larvee of this 
parasite, which had evidently just emerged from the bodies 
of the former (cf. Trans. Devon. Assoc. 1901, p. 666). 
Nordlinger bred #upelmus imermis* from an_ ailing 
beech in the Swabian Alps, in Wiirtemburg, in which this 
beetle, among others, was boring (Ichn. d. Forst. 11, 152). 
28. Oryctes nasicornis, Linn.* 
In his Wirths-system, Ratzeburg simply gives (Ichn. d. 
Forst. 1, 215) Pimpla instigator, Fab., as parasitic upon 
Scarabeus nasicornis ; no mention of it seems to appear in 
the text. 
29. Buprestide. 
Most of the unspecified Buprestes given by Rateebure 
(lab. cit. 1, 23; 1, 212; in, 249) are either subsequently 
1 This record must, I think, be based upon Passerini’s “ Osser- 
vazioni sulle Larve, Ninfe, ete.” (Pise, 1840 ; cf. also Guérin-Méneville 
in Revue Zoolog. 1841, p. 240). He found that Scolia flavifrons 
places its eggs on the larva of Oryctes nasicornis, and the larvee when 
hatched feed by introducing the three capital segments into the belly 
of the beetle-caterpullar, always between the sixth and seventh 
segments (cf. Kirby and Spence, Introd. 7th Ed. 1859, p. 195). This 
parasitic Fosser is not British; “the genus Tiphia is the only 
representative of the family Scoliader, being closely allied to the genus 
Scolia. .... Tiphia femorata, I hay e every reason to believe, ‘to be 
the parasite of a species of Aphodius; I have several times found it 
beneath the droppings of cows and horses” (Smith, Ent. Ann. 1862, 
p. 77). Gravenhorst, of course, mentions no Aculeata, but gives 
Ichneumon flavifrons, Schr., with a note that Schaffer’s figure of it 
resembles Pimpla instigator, Fab. Ratzeburg, it is highly “probable,
