Show 364 MR. H. H. DRUCE O N T H E [June 2, is a short description of N. lineata, Murray:-Male. Upper-side brownish silvery blue, browner at apex. Underside chestnut-brown, with bands much as in N. vinculo, but narrower and not bordered with white as in the female. THYSONOTIS, Hiibn. I have followed Herr Semper in using Hiibner's name for this group. There is apparently nothing but what Mr. de Nicevile calls " facies " to distinguish it from Nacaduba. THYSONOTIS KRUERA, sp. n. (Plate XXXI. figs. 16 J, 17 2 •) Male. Upperside dark violaceous blue, narrowly margined with dark brown ; cilia dark brown. Underside pure white, with costal and outer margins of primaries dark brown, broadest at the base. Secondaries brown at the base and the outer margin, on which is a row of small, irregular, metallic blue spots with a few scales above them towards the anal angle; a few metallic scales near the base just outside the brown. Female. Upperside dull greyish brown, with the disk, from the base, dull light violaceous blue ; hind wing with the outer margin darkest, slightly bluish towards the base. Underside as in male. Head and thorax dark brown; abdomen brown, annulated with white as the bases of the segments ; antennae and legs dark brown spotted with white. Expanse, 6 2 Ijo inch- N o tail* Florida 1.(6). N.W. Bay, Malaita I. ( $ ). This species is allied to T. hymetus, Feld., from Amboina, but is darker blue above, and the female is very different, and to T.piepersii, Snellen, from Celebes. THYSONOTIS CEPHEIS, sp. n. (Plate XXXII. figs. 16,22-) Male. Upperside silky violaceous blue, with the margins narrowly and evenly black ; lighter in the disk of the fore wing. Underside allied to T. schaeffera, Esch., but suffused with more brilliant green at the bases and with the outer-marginal band enclosing the black spots, which in that species is light buff, brilliant metallic green. Female. Upperside as in T. schaeffera, Esch., female. Underside as in male. Head and palpi greenish white ; thorax and abdomen brown ; legs brown and white. Expanse, 6 l j V U incu» ? 1-rV incn- Aola, Guadalcanar I. In some specimens the outer border only of the band on the underside of hind wing is metallic green, the inner border being buff as in T. schaeffera, Esch. T. cepheis can be at once distinguished from that species by the upperside of male being almost entirely blue, in that respect resembling another allied species, viz. T. calydonica, Feld., from New Caledonia, which has been placed as a synonym of T. schaeffera by |
