. Fig. 38. Antenna of D. longicornis, d", from the inside. X 65. almost twice as long as the head, third joint long, the apical part attenuated, pointed and turned upwards with the apex; it is distinctly haired; the arista is inserted behind the middle; the antennae are yellow, the two basal joints black above and the third joint black above and with the apical part black. Thorax dullish green, some- times more seneous, and there may be a golden or coppery middle stripe; it is distinctly greyish or brownish pruinose, slightly shining; scutellum finely yellow pubescent; postscutellum almost quite grey. Pleura greenish, grey pruinose; propleura with a few, fine and pale hairs and a black prothoracic bristle. Abdomen green or golden green, often with coppery reflexes; there are narrow, dark hind mar- gins to the segments; abdomen is clothed with short, black hairs, and has somewhat short hindmarginal bristles, a little longer on the first segment; down the sides there may be some yellowish hairs. Venter greenish grey, slightly pale-haired. The hypopygium is quite different from that in acuticornis; it is black or aeneous black, greyish pruinose; eighth segment with black hairs; there are slightly pro- jecting, somewhat broad posterior ventral lobes with a little point at the upper apical corner, and with a very fine hair; the middle lobes a little projecting; the inner lamellae of usual shape, curved down- wards, the median thin, the lateral dilated, with some spines; the outer lamella somewhat ovate, white, with a not quite narrow, blackish margin along the ventral, apical and the half part of the dorsal edge; at the end there are some teeth with black, curved hairs, and dor- sally to these two strong hairs; the teeth decrease in length towards the ventral margin, which has long, paler hairs, and on the inner side inwards curved, pale hairs. Legs yellow; front coxae whitish pruinose anteriorly, middle coxae grey, with yellow apex, hind coxae yellow, only with a s
