Primaries semitransparent smoky brown, basal half crossed by three black bands, the innermost near the base three times as broad as the others, the outermost diffused, oblique, crossing the wing at the end of the cell; base grey ; secondaries with apical area to first median branch semitransparent brown ; anal-abdominal area opaque, black-brown; nervures blackish; costa silvery white; head, palpi, and antennse above dull black ; thorax bright golden yellow, collar blackish behind : abdomen black; the third, fourth, fifth, and sixth segments clothed with yellow hairs, with yellow-tipped black lateral tufts ; anal tuft black ; wings below somewhat lilacine, black-brown at base, veins black ; palpi below slate-coloured ; thorax dark brown, yellow at base of wings ; abdomen black, segments slate-coloured at the margins. Expanse of wings 2 inches 11 lines. Shanghai, China. Type, c°h. F. Moore. This handsome species is allied to S. uniformis and S. ventralis. The species of Sataspes appear to mimic Xylocopa astuans and X. flavonigrescens. Genus HEMARIS, Dalman. 2. H E M A R I S M A N D A R I N A , n. sp. (Plate X X X V I . fig. 2.) Nearly allied to H. sieboldi (whitelyi, Butl.), but differs in the coloration of the secondaries (which is like that of H. radians), the basal and abdominal areas above being ochreous, the costa pale yellow ; primaries below with basal half of costa ochreous; inner margin pale yellow, ochreous in front; secondaries with costa, base, and abdominal area ochreous ; palpi and pectus pale testaceous. Expanse of wings 2 inches 1 line. Shanghai, China. Type, coll. F. Moore. This species bears much the same relation to H. radians that H. sieboldi does to H. alternata, the dark brown border of primaries being strongly denticulated in H. radians and H. alternata, but entire in H. sieboldi and H. mandarina. Genus RHOPALOPSYCHE, n. gen. Allied to Macroglossa, but at once distinguished by the distinctly clubbed antennse, resembling those of a Hesperidian butterfly : the wings are also somewhat shorter and the terminal joint of palpi more prominent. Type, B. nycteris of Kollar. 3. RHOPALOPSYCHE BIFASCIATA, n. sp. (Plate XXXVI. fig. 4.) Primaries with basal two thirds and outer margin brownish cinereous, disk red-brown; two parallel central transverse dark brown bands: secondaries orange-yellow; outer margin, except at anal angle, rather broadly dark brown : body brownish grey ; metathorax, |
