350 MEETINGS. 



Mr. Luff then read the following notes : — 



" I have great pleasure in recording the addition of a 

 non-British species of Diptera to the Guernsey list : — Masi- 

 ceraferruginea; it was kindly determined and named by Dr. 

 Mead, of Bradford. 



" I have this season been able to assist in working out 

 the life history of a curious little moth, named by Mr. Tutt, 

 .Luffia lapidella. In the second volume of Mr. Tutt's work 

 on the British Lepidoptera a full description will be given of 

 the egg, larva, pupa, and perfect insect ; also of a species of 

 Ichneumon Fly, bred from the larva, from Guernsey speci- 

 mens. The larva lives on lichens on old walls, principally on 

 Lecidea canescens, it also feeds on the bright green alga, 

 Pleurococcus vulgaris, so abundant on shaded damp walls. 

 In the perfect state the female is quite wingless, and clings 

 to the outside of the larvas case, never leaving it. It has a 

 very long ovipositor, with which I have noticed it depositing 

 its eggs inside the old larva case. The male is a very active 

 winged moth. 



" I have to record the first occurrence of the Stag 

 Beetle, Lucanus cervus, in Guernsey. This specimen was 

 captured near the Bouet on June 28th, and brought by its 

 captor to Mr. Collenette. It is a male, and as it had been 

 put into a bottle that had contained paraffin, it did not long 

 survive. In a letter from the late Dr. F. C. Lukis to William 

 Yarrell, published in " Rambles among the Channel Islands 

 by a Naturalist," he mentions, amongst other insects, the total 

 absence of Lucanus cervus from Guernsey. 



" I received a Dragon Fly from Mr. E. D. Marquand, 

 captured in Alderney last week. It is most likely Libellula 

 striolatum* Mr. Marquand saw several other specimens. 

 This is the first record of the capture of any Dragon Fly in 

 Alderney. The Rev. F. A. Walker saw a specimen, but did 

 not capture it. 



" I have succeeded in procuring living specimens of the 

 Aphis, mentioned in the January meeting as found incrusted 

 on poplar twigs. Mr. Buckton, F.Z.8., pronounces these to 

 be Cladobius populeas, Koch, a species not well known in 

 England, but found on the continent." 



Monthly Meeting held on September 20th, 1899, Mr. W. A. 

 Luff, President, in the chair. 

 Mr. W. J. Picot, Alderney, was unanimously elected a 

 member. 



* Since ascertained to be Sympetrum fonscolombi, Selys, a very rare British 

 specie6.— W. A. L.
