about one-third of an inch long, its colour is for the most part pale ochreous, the 
back showing paler, with a fine dorsal line of brown; there is also a brown sub- 
dorsal line, followed at an interval by a broader purplish-brown stripe. After this, 
when the larva begins to grow, the ochreous tint becomes colder, and so continues 
till after the last moult. 
When full grown, the lengthis about one and a quarter inches, the figure rather 
slender, cylindrical, being stoutest at the tenth segment, and thence tapering 
almost imperceptibly to the head, which is nearly as wide as the second segment, 
and is flattened and narrowed a little in front ; anal flap ending in two short points, 
whilst from under it projects a pair of longer and more slender points, slightly cur- 
ved inwards, and projecting quite one-sixteenth of an inch; the skin smooth, but 
tranversely wrinkled on the hinder part of each segment, and along the spiracles; the 
larva, when handled, feels tough and stiff. Although the general colouring is pale 
ochreous, yet there are several lines and stripes to be distinguished, and the diffi- 
culty is to speak of these with sufficient clearness, and at the same time not give 
too strong an idea of them. The ground colour pale greyish-ochreous, with a 
pinkish tinge along the sides; a broad paler stripe down the back, having a 
brownish-dark line through its middle, most distinct on the front segments, and 
being edged with a fine brown line; a broad, pale, greyish-buff sub-dorsal stripe, 
beginning on the head, and continued to the extremity of the anal points, bordered 
above by a fine brown line; next a broad lateral stripe (or band) sprinkled closely 
with brown freckles, and bearing two fine pale lines, the lower of which is whitish 
throughout the four last segments, and on the hinder part of each of the others ; 
then the pale, puffed, spiracular ridge bearing the reddish-yellow spiracles ringed 
with brown; under the ridge, just beneath each spiracle, is a longitudinal dark 
brown dash; belly greyish-ochreous with two faint dusky lines; the usual dots 
wide apart, blackish in colour; the lateral band ceases on the front of the thir- 
teenth segment, leaving the anal flap and the long points pale. 
One of my larve was rather darker than the others, with the ground of the 
back browner, and the lateral band formed of purplish-brown freckles and specks ; 
but even the darkest looked cold-tinted and pale. 
When ait rest, the larva remains stretched out at full length, but curls up the 
front segments when disturbed, and, if further annoyed, drops from its food, and 
curls its whole body up tightly in the same plane, bringing the anal legs and flap 
tightly down on the inner coil, and in this position will allow itself to be trundled 
like a wheel. When about to change, it takes advantage of some small insterstice 
between two bits of earth, or sticks or stones, and, spinning a few threads, draws 
some small, loose particles together to hide the opening. The pupa islong and slen- 
der; the head, wing cases, and last segment of the abdomen, are very dark, shining 
brown; the rest of the abdomen of a pale tint of warm red-brown, with spots and 
tranverse streaks of the darker colour.—J. Hrtuins, Exeter, July, 1871. 
Success of the American Moth Trap.—About a fortnight ago I determined to 
give my “American Moth Trap” a trial, especially as I had at the time the pleasure 
of the company of my friend Mr. W. F. Wheeler, who was anxious to see how it 
worked.
