The upper wings are white and covered with longish loose scales.  Near the base is a narrowish transverse dark brown band, with another considerably before the middle of the wing running parallel to it; behind the middle there is a third band, the inner extremity being at the same distance from the second band as the second is from the first; but it gradually slopes away towards the outer margin, and is thus nearly parallel to the posterior margin, which has also a brown band, scolloped behind, and with at least eight spots on the margin, which is of a brownish yellow, as in the outer margin.

The under-wings, from the base to the middle, and (narrowly) on the outer margin and behind, are brownish ochrey; the other half of the wing is blackish brown, scolloped behind; and having an indistinct ochrey band passing transverse through it, which ochrey band has some darker-coloured scales mixed with it.

The undersides of both wings differ but little from the upper sides; the upper pair more especially however have on the basal and submarginal parts longish ochrey coloured hairs instead of white scales.

The body above is, at the base, ochrey; the sides, and two or three other segments brownish black, darkest just in front of the large thick-set tuft of brownish orange hairs at the extremity; beneath, down the middle, is a band of brownish orange, the segments to the sides of this being black at the base and orange at the tip; the legs are varied with black and ochrey white.

This seems congeneric with the Arcturus sparshalli of Mr. Curtis, described in the 7th volume of the British Entomology, folio 336, as a British insect; but there seems doubt of the correctness of this.  The name, having been pre-occupied in Natural History, has been changed by Mr. Westwood to Trichetra, in page 92 of the Generic Synopsis, appended to his Introduction to the modern Classification of Insects.

The Bombyx tristis is figured (figure 2) on the same block with the T. Nephthis.

Agagles amicus, new species.

A new species, at first sight resembling Leptosoma annulatum, Boisduval (Voyage de l’Astrolabe 1 page 197 plate 5 figure 9) but differs; the thorax having four longitudinal, narrow, light-coloured lines, the band across the upper wings is more continuous, and the circular spot on lower, larger.  It is about the same size, and has the body ringed with black and yellow; the legs are brown; the femora on underside fringed with whitish hairs, simply pectinated; many of the pectinations of the antennae end in a bristle-like hair; palpi somewhat prominent; last joint pointed.

The illustrative figures were drawn by Mr. B. Waterhouse Hawkins, and engraved on wood by Mr. Robert Hart, of Gloucester Street, Queen’s Square.
