rest ; on these segments, also, the dorsal tubercles are elongated transversely, and 
those on the sides are of a drop shape, as seen in some species of the Hepiali; on 
the other segments the tubercles on the back are large in proportion to the size of 
the larva, especially the front pairs, which are thick and transversely oblong, some- 
thing like rather short bricks in shape, and only separated by the before-mentioned 
dorsal line ; the hinder pairs are equally long transversely, but so thin as to be 
almost linear; beneath the oblong pairs of spots there comes on the side a row of 
circular spots one on each segment ; and below these again are situated the minute 
black spiracles with an equally small black dot behind each; a small brownish 
plate is on the anal tip; the legs and prolegs are pale grey, these last tipped with 
brown; a fine short pale brown hair proceeds from each of the spots. Like several 
other larve that dwell in sand, they become, as they mature, of an ochreous 
tint in the ground colour, though their spots remain the same as before. 
The tubular residence of agglutinated particles of sand constructed by this 
active larva is, as Mr. Barrett has previously informed us, four or five inches in 
length, though it varies in this respect according to the growth of the larva, which 
does not appear ever to leave its abode, but to lengthen it in front, while it moves 
on in quest of fresh food, so that the bitten-off stem of the plant on which it feeds 
appears to grow from the mouth of the tube: the hinder end of this is densely 
packed with frass of a whity-brownish or greenish colour, and evidently composed 
of small bits of grass stems scarcely altered by any digestive process. 
The larvz I had in confinement within a pot of sand, furnished with a growing 
plant of their native food, Triticum junceum, did not, after being turned out of 
their cases for inspection, spin any new ones, nor did they re-enter their previous 
abodes, but wandered about and spun a great quantity of useless web along the 
sides of the pot at the edge of the sand, and joined some of their deserted tubes 
together into a tangled mass, and finally contrived to gnaw ahole in their covering 
of new stiff muslin, and thus escaped. 
The cocoon spun by the full-fed larva, and in which it completes its change to 
the pupa, is attached to the former opening of its previous residence at right 
angles, and in a perpendicular position ; it varies in length from one to two inches, 
probably in proportion to the depth of the tube in the shifting sand, though one 
inch and a half is the average length; cylindrical, thick as a goose-quill at the top, 
and a little larger at the bottom, with both ends rounded; the point of junction 
With its former abode is nearly midway, but nearer the top than the bottom; its 
exterior composed of sand similarly to the tubes, but the well lined interior is 
much firmer, and is beautifully smooth with white silk, very tough and strong. 
The pupa is from five to six lines in length, very pale shining brown in colour, 
and quite of an ordinary slender form, only the wing covers are seen to be very 
long in proportion to its size.—WM. BuckLEeR, Emsworth, October 5th, 1870. 
Captures, Sc., of Lepidoptera near York.—The following species have been 
captured or bred by me from 1868 to 1870. A variety of Amphidasis betularia 3, 
in May, 1868, with the upper-wings entirely black and the under-wings broadly 
bordered with black. Collix sparsata; I captured a few spcimens in 1868, and also 
a larva from which I bred a fine specimen in June, 1869. Lycena Alewis; a 
hermaphrodite example fell to my lot in 1868; right side female, left male, the
