pp. 491 — 529, where the various exceptions are fully treated. Lastly, the dis- 
tinction of the endings -odes and -o'ides (not aides) is unimportant, as pointed out 
by Mr. Dunning. The former termination is (in Greek) only a contraction of the 
latter. The canon mentioned by me was laid down by Burmeister, I believe, but 
have not the book at hand. I shall be glad to leave the word Mliodes as it stands^ 
I may take this opportunity of objecting to another class of words, scattered 
sparingly through entomological works, viz., formicosformis, muscceformis, tipulce- 
formis, tor formiciformis, musciformis, and typuliformis. I have also noticed athalice- 
perda, for athaliiperda. — T. A. Marshall, Barnstaple, January, 1869. 
Entomological Society of London, 4<tli January, 1869. H. W. Bates, Esq., 
F.Z.S., President, in the Chair. 
W. F. Kirby, Esq., of the Royal Dublin Society (formerly a subscriber), and 
E. Holdaworth, Esq., of Shanghai, were elected Members. 
Mr. Bond exhibited examples of Vanessa urticm of very small size ; he had 
bred a large number from one brood of larvae during 1868, and attributed the 
diminutiveness of the imago to rapid development owing to the hot season. He 
also exhibited varieties of Apatura Iris and Pamphila comma. 
Mr. Meek exhibited two beautiful specimens of Dianthcecia Ba/rrettii, captured 
by Mr. C. S. Gregson, in Ireland. 
Mr. W. C. Boyd exhibited an example of Cramhus myelins, captured by his 
cousin, Mr. Adam Boyd, near Blair Athol. 
Mr. Home, late judge in N. W. India (present as a visitor) exhibited a fine 
series of the nests of many species of Indian bees and wasps, accompanied by 
specimens of the insects forming them, and by drawings made from the fresh 
nests. Among them were nests formed in the hollow interior of the handle of an 
earthenware vase, in the interior of the hay-nest of a mouse, attached to a signet- 
ring, &c., &c. Mr. Home remarked on the abundance of these insects in India, 
and on the rapidity with which they seized upon available positions for nest-building, 
such as the interior of door-locks, &o. 
Professor Westwood said that apropos of the bees-nest in the interior of a 
mouse-nest, he had observed a contrary instance in his own bee-hives, a mouse 
having chosen one of them as a place wherein to build its nest ; apparently killing 
the bees, but devouring only their heads. 
Mr. Eaton sent a note on the structure of the ovipositor, bearing upon the 
writings of Dr. Packard, M. Lacaze-Duthiers, and his own, on that subject. 
Mr. F. Smith read a paper upon the afl&nities of Sihyllina, an anomalous 
Hymenopterons genus described recently by Professor Westwood. Mr. Smith 
combated Prof. Westwood'a suggestion that the genus pertained to the Vespidce, 
and was inclined to refer it to the IchneumonidoB, as having some affinity with 
Anomalon, &e. Prof. Westwood remarked that Mr. Cresson had recently described 
a genus which he believed to be identical with Siiyllina, and also referred it to the 
Ichneumonidce. 
Professor Westwood exhibited drawings of various anomalous forms in Coleop- 
tera, and of an Ichneumon, the larva of which was an external parasite on a spider. 
Mr. E. Saunders read " Descriptions of nine new species of Buprestidc^."
