Show 344 MR. W. F. KIRBY ON HYMENOPTERA [May 1, ones on the front border, adjoining those on the prothorax, a longitudinal one between, then two slightly oval ones near the middle, and a large irregular spot behind on each side, projecting a branch forward within the very large black tegulae; scutellum black, strongly excavated in the middle; abdomen with the first segment blue, a narrow longitudinal line, the greater part of the hind border, and a long transverse spot contiguous to it black; the remaining segments of the abdomen are black, with a wide blue stripe sloping slightly upwards on each side; legs black, all the tibiae with a wide blue stripe on the outside; wings dark purplish brown. (2128, Maroe.) Allied to C. nitidula, Fabr., a species common in Amboina, Australia, & c , but apparently distinct. XYLOCOPA FORBESII, sp. n. Long. corp. 10 lin. Male. Thickly clothed above with olive-green pubescence, as in the male of X. astuans, Linn., or of X. bryorum, Fabr.; antennae black above and fulvous beneath, the hairs on the middle of the under surface of the body, especially towards the tip, those on the lower part of the face, and the very long hairs on the tarsi shading into fulvo-ferruginous; wings brownish hyaline, with a slight violet shade, and marked on all the cells along the hind margin with numerous black dots, as in the allied species; proboscis black, probably reddish within and at the base when extended. (1988, Larat.) Female. Black, thickly clothed with black hairs, and very tbickly and finely punctured, except on the middle of the mesothorax, which is smooth and shining, and has a short longitudinal furrow in front; head clothed with bright yellow pubescence, that on the face thinner and paler; wings with a bright green iridescence, purplish along the veins towards the base; apical half of the antennae pale beneath; proboscis mostly reddish ; under surface of body thickly punctured, but with some bare spaces along the middle line. (1958, Larat; 2019,-Maroe.) Closely allied to X. coronata, Smith, from Kaioa; but in the female of that species (which doubtless has a male similar to that of X. forbesii) the wings have a bright violet instead of a green iridescence. VESPID-E. POLISTES EXTRANEUS, Sp. 11. Long. corp. 5 lin. Female. Head and thorax bright chestnut ; clypeus pentagonal, bright yellow ; mandibles with a yellow mark on each side ; antennae dull yellow ; the scape, second joint, and upper part of the third reddish ; prothorax narrowly edged with yellow in front and behind ; scutellum with a transverse yellow line ; metathorax edged with yellow on the sides ; abdomen with the first joint yellow, with a broad red stripe, bordered behind with black, extending for two thirds of its length above, second and third segments blackish |
