. British entomology; being illustrations and descriptions of the genera of insects found in Great Britain and Ireland: containing coloured figures from nature of the most rare and beautiful species, and in many instances of the plants upon which they are found. induced to give naturalists the benefitof their researches in the two families they have so success-fully studied, by publishing the characters of the genera andspecies of these minute but beautiful tribes, of which Mr. Hali-day has made most admirable dissections, and Mr. Walkerhas formed a collection embracing at least 700 British species. The minute Hymenoptera are best collected by beatinginto, and sweeping with, a net made of fine gauze, and recommends me to collect them into quills, and after-wards to empty their contents into hot water, by which meanstheir wings are naturally expanded; then by introducing acard under them to take them out of the water, arranging thelegs and wings when necessary with a camels hair pencil, andleaving them upon the card till they are dry, they may after-wards be taken off with a penknife, and gummed upon thepoints of small pieces of drawing- or card-paper of a long tri-angular form. The plant is Galium vemm (Yellow Ladys Bed-straw). 24g. :./; HALIDAYI. Order Hymenoptera. Fam. ProctotrupidaeAbi. OxyuriZ,a/. Type of the Genus Ceraphron sulcatus Jur., Spin., Lat., Leach.
