the exposed island of Lewis, said that there the cocoon was 

 placed horizontally and not vertically, as the growth of moss 

 and heather was insufficiently deep to admit of that posi- 

 tion being used. Dr. Chapman mentioned that he had once 

 found the ova of Lasiocampa quercifolia on hornbeam, two 

 or three in a group. 



Herr Ernst Heyne said that Lasiocampa ilicifolia is rare in 

 Saxony and Bohemia, but not so scarce in Silesia. In 

 Silesia sometimes the red aberration rubra had been found ; 

 but it is very scarce, perhaps only one in fifty specimens. 

 Several years ago a small number of larvae were found in 

 the beginning of August on the hills " Hohburger Schweiz " 

 near Leipzig. He visited the locality a week later, but all 

 were then gone. 



Mr. Tutt stated that he had hitherto supposed the red 

 form of L. ilicifolia peculiar to England. 



MARCH ioth, 1898. 



Mr. J. W. Tutt, F.E.S., President, in the Chair. 



Mr. H. Donisthorpe, F.E.S., 73, West Cornwall Road, 

 Mr. F. Bouskell, F.E.S., Leicester. Mr. F. Lemann, 

 F.E.S., Plymouth, Mr. Parkin, Battersea, and Mr. Bevins, of 

 Clapham Common, were elected members. 



Mr. Frederick Clark exhibited a large number of photo- 

 micrographic slides with the aid of the Society's lantern. 

 The subjects were all entomological, and embraced most of 

 the typical structures, e. g. the antennae, eyes, probosces, 

 feet and wings, &c, of the various orders. Many of these 

 were of considerable interest, particularly the wing and 

 scales of Pscudopontia paradoxa, a lepidopterous insect of the 

 West African fauna and the only species of the genus, from 

 specimens kindly lent by Mr. Harry Moore. The peculiarity 

 of this insect lies in the shape of the scales, the majority of 

 which are bifid in varying degrees, and cover the wing 

 alternately with scales of a commoner form. A number of 

 parasites, human and otherwise, were also shown. 



Mr. Lucas also exhibited some slides in the lantern. The 

 subjects were as follows, the first half-dozen having been 

 prepared for him by Mr. Clark : Jaws of Anax imperator 

 (nymph). Nymph of Symprtrum striolatum, just hatched. 

 Claws and mask of Calopteryx splendens (nymph). Mask of 

 Erythromma naias (nymph). Legs of Erythromma naias 

 (nymph). Lamella of Erythromma naias (nymph), very fine
