28 Mr. Ernest A. Elliott and Mr. Claude Morley on the 
90. Strangalia quadrifasciata, Linn. 
Marshall’s record (Bracon. d’Europ. 11, 219) of Helcon 
ruspator, Linn. “Parasite du longicorne Strangalia 
quadrifasciata, L.,” is the only one known, 
91. Grammoptera ruficornis, Fab. 
Morley, confirming Helcon annulicornis, Nees, as British 
(KE. M. M. 1900, p. 175), writes: “I should suspect it, from 
the state of its environment when found in the present 
instance,” to prey upon “Grammoptera ruficornis, F., .. . 
If, however, it be parasitic upon so ubiquitous a host, it 
appears curious that it should for so long have been over- 
looked.” And, moreover, the relative size of host and 
parasite render such an association highly improbable. 
92. Acanthocinus xedilis, Linn. 
NXorides filiformis™ under fir bark (Ichn. d. Forst. i, 123), 
X, irrigator®™ of which the almost black and boat-shaped 
cocoon was found side by side with that of its host in dry 
wood (ili, 105), and Bracon initiator ! (4, 46 et 11, 39) are 
instanced as parasites of this interesting Longicorn by 
Ratzeburg (ii, 212), to which is somewhat doubtfully 
added (iii, 36) Bracon precisus, upon the authority of 
Brischke, who saw on 23rd May six of these parasites 
emerge from a hole of Cerambyx exdilis in a fence post. 
93. Leiopus. 
Giraud indicates an unspecified individual of this genus 
to have been the host of Orthocentrus fulvipes, Grav. (Ann. 
Soc. Fr. 1877, p. 408); it was bred in France by M. Edouard 
Perris. 
94, Letopus nebulosus, Linn. 
From this species has been bred by Dr. Fromont, accord- 
ing to Tosquinet (Ann. Soc. Belg. 1897, p. 322), Mitroboris 
cornuta,’® Ratz. ; and Laboulbene also says (Ann. Soc. Fr, 
1877, p. 411) that MMeteorus tabidus, Wesm., was raised 
from it by Perris. 
95. Hoplosia fennica, Payk.* 
From Cerambyx fennicus, Ratzeburg records (Ichn. d. 
Forst. ii, 212) Hphialtes tuberculatus, Xorides filiformis 
bred by Reissig from its own brown, papyraceous cocoons
