"This discovery is one of much interest, proving the relationship of the insect to be amongst the pupivora, to which family it had been previously assigned by Mr. Westwood, see Volume 3 Ent. Transactions page 270. The specimen is seven lines in length, entirely black, the head shining, the thorax and abdomen opaque, and having two white maculae touching the apical margin of the basal segment above; the wings are smoky, the antennae broken off. Of one of them I found subsequently seventeen joints--the perfect insect in the possession of Mr. Saunders having twenty joints."
LEPIDOPTERA.
Drusilla myloecha, Tab. 4 fig. 3, 4.
This fine butterfly* was found flying in considerable plenty in the woods of one of the islands of the Louisiade Archipelago; it forms a very interesting addition to a genus, of which but few species are known, and is allied to the Drusilla catops of Dr. Boisduval, described and figured in the Voyage de l'Astrolabe. The upper sides of the wings of the Drusilla myloecha are of pure white with a silky lustre, the front edge of the fore wings margined with deep brown both above and below; in the male there is a slender white line on the upper side running close to the edge, and extending beyond the middle of it; the two discoidal veins in the male are brown on the upper side, and the edge of the upper side of the lower wings is brown. The under side of the lower wings has a dark brown band at the base, widest close to the attachment of the wing and narrowing to a large ocellus which it surrounds in the form of a narrow brown ring; the black ocellus has a very small white pupil with a slight bluish crescent on the inside, and is surrounded by a fulvous ring; thcre is a second black ocellus nearer the hind edge than the middle, with a small white pupil and a wideish fulvous ring, separated from the white of the wing by a narrow brown ring; head, antennae, legs, and thorax in front brown; palpi fulvous.
The figures are of the size of nature, and carefully drawn by Mr. Wing.

Eusemia mariana, Tab. 4 fig. 5.
E. alis coerulescenti-nigris; anticis albo-fasciatis et maculatis, posticis croceo-maculatis.*
(*Footnote. Filiae meae "Marian Frances White," speciem hanc pulchram d.d. descriptor.)
Upper wings black, with a slight bluish tinge; a wide band extends across the wing before the middle; it is white with a slight yellowish tint, at the lower edge of the wing it is abruptly narrowed; behind the middle of the wing, and between it and the tip, are from five to six pale yellowish white spots, the four or five outermost the smallest, and one or two of them sometimes obsolete; between the base and the band a narrow bluish grey line extends across the wing, and behind the band, at an equal distance, there is another short, waved, bluish grey line running down to the inner margin. The margins of the band and spots are bluish grey. The lower wing is narrowly black at the base, with a transverse band of a king's yellow colour; this is the widest on the inner edge, near its outer end there is an angular black spot; the apical half of the wing is black, with numerous king's yellow spots arranged in two lines, two spots about the middle connected and notched with black. Head, thorax, and base of abdomen black, rest of abdomen of a king's yellow colour.
