DESCRIPTIONS OF SOME NEW SPECIES OF ANNULOSA COLLECTED BY MR.

MACGILLIVRAY DURING THE VOYAGE OF H.M.S. RATTLESNAKE, BY ADAM WHITE, ESQUIRE, F.L.S., a.s.sISTANT ZOOLOGICAL DEPARTMENT, BRITISH MUSEUM.

Among the very numerous Insects and Crustacea, collected by Mr.

Macgillivray during the voyage of the Rattlesnake, the following have been selected for ill.u.s.tration; references to and descriptions of some of the Diptera, h.o.m.optera, and Hemiptera, collected by him, have appeared in the Catalogues of the British Museum drawn up hy Messrs. Walker and Dallas, while the names and descriptions of others will appear in catalogues in preparation. A fine species of the cla.s.s Crustacea, discovered by him, has been described and figured in the Ill.u.s.trated Proceedings of the Zoological Society. (Cancer [Galene] dorsalis, White.)

INSECTS. COLEOPTERA.

Chrysodema pistor, Laporte and Gory. Buprestidae, t. 6, f. 33.

Habitat: Australia (Cape Upstart). Mr. Macgillivray informs me, that the specimens of this species were observed by him coming out of a dead tree (Casuarina).

Pachyrhynchus stanleya.n.u.s.* Tab. 4 fig. 1, 2.

(*Footnote. In memoriam Owen Stanley, in cla.s.se Britannica Navarchi, species haec distincta et peculiaris nominatur.)

Pachyrhynchus nigerrimus, maculis parvis squamosis plurimis viridiscenti-albidis.

Habitat: Pariwara Islands, New Guinea. Four specimens.

Head between the eyes somewhat rugose, some of the rugose punctures with pale greenish white scales; an abbreviated longitudinal impressed line down the front. Beak short and thick (somewhat as in Pachyrhynchus c.u.mingii, Waterhouse). Thorax irregularly and somewhat coa.r.s.ely punctured, the sides somewhat wrinkled in front, the punctures scaled, a triangular depression on the posterior part of thorax, the bottom is covered with scales, at least in some specimens, and there are three spots similarly scaled and placed somewhat transversely: the Elytra with eight to ten punctured lines, running somewhat irregularly, especially towards the sides, each elytra with ten, twelve, or more spots of scales, arranged longitudinally in spots on the sides, and largest towards the end. Underside of the mesothorax and metathorax with many greenish scales. Legs thick, polished, and with scattered grey hairs proceeding from the punctures.

I have named this somewhat mourning Pachyrhynchus after Captain Owen Stanley and his father, the late venerable Bishop of Norwich and President of the Linnean Society. Both of these gentlemen were fond of natural history, especially the father, who was a good observer of the habits of birds. The son, Captain Owen Stanley, was an accurate, though not very practised draughtsman; and I recollect with pleasure his pointing out to me, at one of the soirees at Brook Street, a volume of sketches (coloured) made by him on one of his voyages, in which objects of natural history were ably introduced. He encouraged natural history researches.
