ASTATHES TERMINATA, Pascoe, Trans. Ent. Soc. ser. 2. iv. p. 109. Varies in the extent and depth of the yellow at the apex of the elytra ; the abdomen is also frequently more yellowish than brown. In some examples a sort of areola may be noticed round the punctures on the posterior part of the elytra, a peculiarity which is very remarkable in A. perplexa, Newm. ASTATHES NIGRICORNIS, J. Thomson, Syst. Ceramb. p. 560. An entirely fulvous species, with black antenna?. A marked callosity on each side of the prothorax will distinguish it from an undescribed species from Morty with a similar coloration. A fourth species, with the antennae imperfect, is in the collection. It has a yellow head, with a dusky patch behind each eye ; otherwise it approaches very closely to an undescribed species from Singapore. The distribution of the two colours, blue and yellow, and the intensity of the black, are too variable in this genus to carry much weight in the determination of the species. The Astatheinar are remarkable for the peculiar modification of the metasternum : this is prolonged anteriorly between the intermediate coxae, so as to completely overlap that part of the mesosternum lying between them. PHYTOJXIIN^E. GLENEA. Glenea, Newman, The Entom. p. 301. Sphenura, Laporte de Castelnau, Hist. Nat. des Ins. ii. p. 489, 1840 (nee Lichtenstein, 1823). GLENEA ELEGANS. Saperda elegans, Olivier, Colcop. iv. no. 68. p. 15, pi. 4. f. 40 (1795). Stenocorus pictus, Fabricius, Syst. Eleuth. ii. p. 306 (1801). Of this extensive and very difficult genus I have about twelve species or quasi-$\iec\e§, which may be probably referable to Olivier's Saperda elegans. They are all of the richest metallic blue, with snowy-white spots and stripes, varying in length from 8 lines to If inch. The spots and stripes are without doubt very uncertain characters, and the minor differences, for there are no others, are very unsatisfactory on paper. Nevertheless it may be perhaps necessary to name some of the extreme forms. Mr. Lamb's specimens have yellow legs ; but this scarcely seems of specific importance. Glenea delia, J. Thorns., from the character " humeris fere nullis," is doubtless distinct. Another Glenea in the collection has the elytra rapidly narrowing from the shoulders, and rather suddenly rounded near the apex, which is much narrower and at the same time more |
