specimens that I have seen of A. spreta are from Deal. Two other 

 very local Carabidce also occur here with A. famelica ; these are 

 Harpalus discoideus and Bemhidium nif/riconie.

THE SUPPOSED ARGYRESTHIA ILLUMINATELLA, Z. 



\_vide Wlsm., Ent. Mo. Mag., XXX, 50-1 (1891)]. 



BY THE BIGHT HON. LORD WALSINGHAM, M.A., LL.D., F.R S. 



In the language of the Western American I am disposed " to 

 weaken on it." 



A re-examination of Zeller's series of illuminatella in the course 

 of a successful search among them for A. Atmoriella, Bankes, has 

 convinced me that there are at least three species included by Zeller 

 under the above name. It is exceedingly difficult to determine which 

 of these species should be regarded as the one to which Zeller 

 originally gave the name, but his oldest specimens have on them two 

 names, ^'' illuminatella, Ti.," and the unpublished one, "glaherrimella, Ti." 

 The specimen labelled by him with a reference to his original 

 description (Isis, 1839, 205), is probably the one subsequently referred 

 to in his paper [Lin., Ent., II, 291-2 (1847)], but there is strong reason 

 to believe that he had not this specimen before him when he wrote 

 the notice in the Isis where the following short description might well 

 be taken to refer to specimens in his series extremely similar to those 

 collected by Mr. Salvage at Porres : " der Prwcocella sehr nahe, aber die 

 Vorderfl. fast strohgelb und glanzender, ohne Yerdunkelung des 

 Mittelraumcs." 



In his subsequent more elaborate description eight years later he 

 refers to the breadth of the fore-wings and to the fact that the hind- 

 wings are noticeably broader towards the apex than in prcscocella, 

 although the palpi are thinner and more slender. If his type label 

 were affixed at this date (and it is obvious from the reference it bears 

 to Ratzeburg that it could not have been written before 1840), be 

 would seem to have picked out the broadest-winged specimen in his 

 series with which no other can be regarded as conspecific ; this 

 specimen is labelled "Illuminatella, F.E.,Is., 1839,205, Bergiella, Etz.," 

 and is nearer to certella, Z., and broader in the wings than those which 

 I take to be his original types. 



The description of pnecocella lays emphasis upon the rufesceut 

 suffusion of the wings, and in a long scries of that species in Zeller's 

 cabinet there are only two specimens in which this is not distinguish-
