The Atoll of Funafuti, Ellice group : its zoology, botany, ethnology and general structure based on collections made by Charles Hedley of the Australian Museum, Sydney, N.S.W.
Obs.—Seven species of Coleoptera, which, with the exception of two, were referable to known species, were obtained by Mr. Hedley, and are enumerated below. I am indebted to Mr. George Masters, Curator of the Macleay Museum, and to Mr. T. G. Sloane, for much valuable assistance and information. The following are the known species of Coleoptera obtained from Funafuti:—
|Monocrepidius ferrugineus, Montrouz||One specimen.|
|Monocrepidius umbraculatus, Cand||One specimen.|
|Uloma cavicollis, Fairm||One specimen.|
|Uloma insularis, Guer||One specimen.|
|Sphenophorus sulcipes, Karsch||Four specimens.|
Genus Nacerdes, Schmidt.
Nacerdes transmarina, sp. nov.
(Plate i., fig. 6.)
Long. 14 mm., lat. 4 mm.
Eliptic, elongate, yellowish-brown, thorax narrowed in front and at base, scarcely as long as it is wide.
Head yellowish-brown, obscurely punctate, sparingly clothed with very short and fine yellowish pubescence. Eyes prominent, finely granulated, black. Thorax moderately convex, narrowed in front, truncated, abruptly and strongly bulging out laterally to about one-third its length, thence gradually tapering inwards to its posterior extremity where it is again truncated; disc clothed with very short yellowish pubescence. Elytra somewhat shorter than abdomen, yellowish-brown, moderately arched, obscurely punctate, clothed with short, fine, yellowish pubescence, broadest at the shoulders, gently tapering to abdominal extremity. Mentum small, somewhat concave. Underside concolorous, clothed with exceedingly fine pubescence; sterna obscurely punctate-striate. Legs moderately long, yellow-brown, thickly clothed with short yellowish pubescence, and armed with short black spines at joints. Antennae, concolorous.
Genus Elytrurus, Schonherr.
Elytrurus squamatus, sp. nov.
(Plate i., fig. 7.)
Long. 4 mm., lat. 2 mrn.
Eliptic, robust, bluish-grey; thorax narrowed in front and at base, punctate; elytra, punctate-striate.
Rostrum black, with a broad central shallow depression. Thorax convex, scarcely as broad as long, closely covered with minute shining granules, slightly narrower in front than behind, gradually widening towards the middle, and then narrowing again. Elytra arched, striate-punctate, slightly wider at the shoulders than the thorax at its base, gradually widening towards the middle, thence narrowing again to the apex; the apices acute; the whole surface thickly covered with minute shining granules; there are also a few short hoary hairs towards the apex, and along the sides. The general colour is bluish-grey. Legs and antennæ concolorous, thickly covered with minute shining granules, and furnished with a few short hoary hairs. Antennae long, slender.page 93
Obs.—This was the most representative species of the series collected, fifteen specimens having been obtained. In some of the members there is a slight difference in colouration, some being brownish-grey, but this is doubtless a sexual distinction. The chief interest attaching to this genus, however, is the fact that it is confined solely to the Pacific Islands. The following are the localities from which representatives have hitherto been obtained:—New Hebrides, New Guinea, Fiji, Tahiti, Vanikoro, and Nukuhiva.
Mr. Woodford, in his paper on "The Gilbert Islands,"* gives the following list of species as obtained by him in that group:—? Amarygmus, sp., Pantopoeus guisens, Coccinella transversalis, G. arcuata, Necrobia rufipes, Tribolium ferrugineiom, Dermestes, sp., Carpophilus, sp., Silvanus, sp., C'arcinops (?) sp., Trogosita mauri-tanica, Alphitobiuspiceus, A. diaparinus, Sitophilus, sp., Adelocera modesta, Monocrepidius, sp., Nacerdes, sp. (2), and a genus allied to Tribolium (?) sp.
