CONTRIBUTIONS TO HISTORY OF THE BRITISH PTEROPHORI. 27 
are transparent, and emit hairs as in the subdorsal set. Prolegs and anal 
claspers semitransparent, tipped with pale brown. May and June, on 
convolvulus (Calystegia sepium), eating the leaves and flowers; rests on 
the undersides of leaves and on the stems. 
Puprsa.—Pale green at first, afterwards greyish green, with three rows 
of black dorsal spots; hairs similar to the larval arrangement; fastened by 
the tail to a leaf or stem. May and June.

IT am obliged to Mr. John T. Carrington for a supply of the 
larvee of this species. 
The imago is perhaps more often seen than that of any other 
species of the British plume moths; but although generally 
distributed it is nowhere, I think, so abundant as are one or 
two other species of the family in particular localities. 
Agpistis, Hb. 
benneti, Curt. 
(PuatE I., Fic. 3.) 
Imaco.—Expanse, 10-12 lines. Fore wings entire, tip subacute. 
Ground colour grey, sprinkled with brownish scales; centre of wing and 
towards hind margin slightly ochreous, sometimes rosy; above the inner 
margin are four black dots, the posterior-of which varies in size, in some 
specimens being represented by a mere speck; near the costa and towards 
the apex is another black spot, and in some examples a sixth spot lies near 
the anal angle. Fringes grey-brown. Hind wing entire, hind margin 
slightly indented before the middle, dark grey, smoky at the base and inner 
margin, and anal angle blackish; fringes grey-brown. Head, body and 
legs grey-brown. June and August. 
Larva.—Length, 8 lines; slightly tapering posteriorly. Head smaller 
than 2nd segment, into which it is withdrawn when the larva is at rest; 
the colour is yellowish green; the crown, and a broad patch therefrom 
“nearly to the mandibles on each side, rosy ; a few short bristles are scattered 
over the upper portion of the head. Ground colour green, so thickly 
sprinkled with small white dots as to appear whitish green to the 
unassisted eye; skin considerably roughened and wrinkled laterally; the 
anterior segments are wrinkled dorsally also. No tubercles; the 2nd 
segment has horn-like points protruding from about its middle in a 
horizontal direction, the tips and bases of these are rosy ; the anal segment 
is yellowish green on the sides, violet brown dorsally, and has four bristles 
projecting along its posterior edge at right angles with the claspers;
