and leaf-mining (classed under the Tineae) caterpillars, but the habits 
of the larvae and their mode of feeding are very diverse, and not 
restricted to these two methods, some living in flower-heads, seed- 
vessels, and in galls, others in rotten wood, fungi, etc. Living larvae 
were exhibited by Mr. D. C. Bate, laggards from a second brood, in 
1896, of Oryyia yonostiyma ; and Mr. J. Riches brought up a clump of 
variegated ribbon grass, in the stems of which nearly full-fed larvae 
of Apamea ophiut/ramma were feeding. Mr. C. Nicholson had a preserved 
larva (young) of La&iocampa quercifolia, which showed the “ lappets,” 
which give its popular name. Exotic Lepidoptera. —Exotic Lepidop- 
tera were nearly as numerously represented as British, the principal 
exhibitors being Mr. Stanley Edwards, who favoured the society by 
showing his valuable and immense collection of foreign L’apilioninae, 
etc., from all regions ; Mr. .J. A. Clark, several drawers of tropical 
butterflies (genus Morpho, etc.), and the large silk-producing moths 
(Atlas, Cecrojria, etc.), and fine examples of Thysania ayrippina, 
usually said to be the largest known moth, occurring in Brazil 
and British Guiana; Dr. J. S. Sequeira, many cases of butter¬ 
flies, principally Indian ; Mr. A. Bacot, a large collection of 
Lepidoptera from the Johannesburg and Pretoria districts of S. 
Africa; Mr. E. M. Dadd, butterflies from Dakota, U.S.A., a 
special point of interest being the “ mimicry ” of Anosia archippus 
and Li/nenitis disippus , and the extent of variation of Colias 
eury theme. The subject of “ mimicry,” or the assumption by per¬ 
secuted species of similar or nearly similar coloration to that of species 
protected by scents, colours or presumed nauseousness of flavor, from 
their bird and animal foes, was well illustrated by Messrs. Watkins 
and Doncaster, of the Strand, who sent up three large cases of tropical 
butterflies, whose habits and colours bore on this point. Mr. 0. E. 
Janson also exhibited a case with a similar object. Coleoptera.— 
Turning to other orders, Mr. H. Heasler furnished six cases of British 
Beetles, including Ground, Water, Rove, Club-horn, Leaf-horn, Skip¬ 
jack, Weevil, and Long-horn Beetles, a large proportion of which 
were collected in the 10 mile radius of London, and form the 
material for his “ London List of Coleoptera.” In this district may 
be found such “good things ” as Notiophilus rufipes, Oodes helopioules, 
JJydrophilus piceus, Hydraena testacea, Quedius scitus, PhUonthus 
atratus, Epurea diffusa, Atomana ffmetarii, Aphodiuslividus, Rldnonchm 
bruchoides, Molorchm minor and Tritoma bipustulata. Orthoptera.— 
Mr. O. E. Janson exhibited, in addition to that previously mentioned, 
a case of the extraordinary “ Stick insects.” They were set out for 
study, with legs and antenme extended ; but in their natural habitat, 
lying along branches or twigs of trees and stems of plants with their 
legs, side by side, stretching out before and behind in a straight line 
with their body, which is not much thicker than the legs thus held 
together, they can with difficulty be discerned by the entomologist, 
and escape the notice of the unobservant, and it is presumable this 
is a further development of the “ protective mimicry ” principle. 
Pseuoo-Neuroptera. —Mr. W, J. Ashdown obliged with a selected 
type collection of British Odonata, the following deserving notice : 
Ana.v imperator ( fonnosus), Orthetrum cancellation, Leptetrum quadri- 
macidata with the beautiful var. praenuhila, all from Surrey; 
Cord ale;/aster anmdatus, clear-winged specimens of Cal apteryx splendens
