Wings witiiout costal swelling. Squamular fringe black. Length 4,5—5 mm. H. diadema is not rare in Denmark, but seems to be rather local; Amager, Gharlottenlund; on Funen at Odense; in Jutland at Gjerlev Fig. 17. Wing of H. diadema d- near Randers Fjord and Struer; and on Bornholm. My dates are in July and the first part of August. It occurs at the coast, especially on Carex, often in great number. Geographical distribution: — Europe down into Spain and Sicily, and further iu Egypt; towards the north to middle Scandinavia. 5. Dolicliopus Latr. Species of medium or somewhat large size, and always of metallic, green or seneous colour. Head as broad as, or a little broader than thorax; it is short, about semiglobular, and about as broad as high, or a little broader, especially in the female; it is broader above than below, as the greatest breadth lies above the middle. Occiput slightly arched. Vertex somewhat excavated, and the ocellar tubercle a little prominent. Frons broad, slightly decreasing in breadth towards the antennae, especially in the male, which has the frons a little narrower than the female, in which latter sex it has almost parallel margins. There are ocellar, outer vertical and postvertical bristles, and on the posterior side of the ocellar tubercle a few small hairs. Eyes large, somewhat oval in circumference, metallic green with coppery reflexes in the living specimens; they are densely short-hairy; the facets are in the males very slightly enlarged towards the epistoma. The eyes are separated, more broadly in the female than in the male. The postocular bristles are strong and form a single row; the bristles which are inserted along the oral aperture behind are interrupted in the middle, as there are no bristles just above the apertu
