Lieftinck, M. A.: Bees of the genus Amegilla Friese from Korea with a new species (Hymenoptera, Anthophoridae)

of thorax yellow grey-brown to yellowish brown, without admixture of black,, though many light hairs are tipped with darker brown ; sides and ventral surface greyish white, as are also most parts of the legs, the apices of mid and hind tibiae almost white; spurs black. Hind basitarsus usually predominantly black with a few pale hairs at extreme base only, but disk occasionally sparsely pale all over, the dorsal and ventral ridges dark-haired, as are the inner faces. Abdomen deep black, tergites 1—5 with well defined, though rather narrow, greyish yellow posterior bands, which are parallel-sided and of nearly equal breadth ; these bands are composed of strong appressed hairs, the disks (except of tergite 1) clothed with suberect. deep black and more bristly hairs not concealing the surface and replaced by lighter ones at extreme sides ; long raised hairs covering tergite 1 grey-brown; 6—7 black-haired, apex of 7 with broad, crescent-shaped emargination and well developed lateral prongs. Sternites dark, free margins of 1—5 with narrow fringes of short grey hairs, but those in middle of 5 obscured; 6 reddish brown distally. surface smooth and shallowly concave on either side of a distinct median carina which ends in a raised tubercle carrying a tuf t of dark hairs; posterior border brace-shaped (Fig. 7). Sternites 7—8 and genitalia of very characteristic shape (Figs. 8—10). 9 • Resembles the male in most respects, punctation, colour and nature of pubescence being quite similar. Except for its somewhat larger size, the following differences are worth mentioning. Labrum more markedly broader than long, its free margin rather swollen and upturned in middle, preceded immediately above it by a sharp, minutely tuberculate ridge; disk broadly margined with black, the dark colour at apex also extending back alongside, uniting with a dark stripe at base which broadens laterally so as to include the basal tubercles ; hair covering disk longer than in male, brownish yellow. Light clypeal marks considerably more reduced, restricted to a vertical median stripe and a pair of transverse isolated spots, one on either side, almost in contact with the yellow mandible-bases; the median stripe is a little expanded anteriorly, running from base almost as far as the anterior border, which itself is black. Paraclypeal areas unmarked; supra clypeal spot small, forming an almost equilateral triangle (Fig. 0). Antenna dark, scape invariably lacking a pale anterior spot; joint 3 very long, only little shorter than 4—7 combined, 4—5 distinctly broader than long, 4 being the shortest, 6—7 squarish, last joint at least 1 1/2 times as long as broad and markedly longer than the preceding. Legs brownish black, basal segments light-haired, fore femur with long pale posterior fringes ; mid and hind femora mainly dark, the former with small pale hair-spot below, the latter with whitish tuft partly covering basitibial plate, which is broadly oval and darkrimmed. Outer faces of tibiae pale grey-white, the inner ones dark brown, scopa with blackish exterior hair streak occupying the basal one-third of the total length and tapering to a point apically; basitarsi mainly light-haired externally, these long hairs at hind basitarsi replaced by a more or less triangular patch of white at base and upper margin. Yellowish grey hair bands at apex of gastral tergites 1—4 much as in male, though all a little broader, not coalescent at the sides, which are only sparsely light-haired; tergite 5 black save for a tuft of longish raised white hairs each side, the short very dense apical fringe black; 0 and pygidial plate reddish black, the latter shaped exactly as described for A. florea. Length of body 12.5 mm (çf), 14.5 mm (9 )• A. confusa has apparently no near allies. When the male genital armature .and sternal plates are dissected out and observed, the unique shape of these structures will be evident and should serve to its easy recognition. In fact, I know of no other
