Mr. F. J. Hanbury exhibited, on behalf of Mr. Percy H. 
Russ, of Sligo, several long and very variable series of 
Agrotis tritici, A. valligera, and A. cursoria, together with 
Irish forms of many other species, some of which were 
believed to be new to Ireland. Mr. W. H. B. Fletcher and 
Mr. J. W. Tutt made some remarks on the specimens. 
Mr. R. W. Lloyd exhibited specimens of a species of Acarus 
found in New Zealand wheat. He stated that Mr. A. D. 
Michael had examined the specimens, and pronounced them 
to belong to Tyroglyphus faring, a species which had been 
known for over a hundred years as a destroyer of corn, and 
was only too abundant all over Europe, and probably over 
the temperate regions of the world. 
Dr. T. A. Chapman exhibited, by means of the oxy-hydrogen 
lantern, photographs of the larva of Nemeobius lucina in its 
first stage, showing the conjoined dorsal tubercles, each 
carrying two hairs, which are remarkable in being divided 
into two branches. For comparison he also showed, by 
means of the lantern, drawings of the young larva of Papilio 
ajax, after Scudder, and of a portion of a segment of Smerin- 
thus populi, as the only instances known to him of similar 
dichotomous hairs in lepidopterous larve. 
Mr. E. B. Poulton pointed out that he had described the 
forked hairs of Smerinthus in the Entomological Society’s 
‘ Transactions’ for 1885, and that such hairs were even better 
developed in the genus Hemaris originally described, as he 
believed, by Curtis. Mr. Poulton also said that he had 
noticed similar forked hairs covering the newly hatched 
larvee of Geometra papilionaria. 
Mr. Poulton exhibited, and made remarks on, a number of 
cocoons of Halias prasinana, in order to show the changes of 
colour produced in them by their surroundings; he also ex- 
hibited the coloured backgrounds employed by him in his recent 
experiments on the colours of larve and pup, and illustrated 
his remarks by numerous drawings on the black-board.

Dr. Chapman read a paper—which was illustrated by the 
oxy-hydrogen lantern—entitled ‘‘On some neglected Points
