1871.: 69 
it may be supposed how much I rejoiced at the success of his expedition, when, on 
the 16th of May last, I had the pleasure of receiving from him a consignment of 
growing plants of Elymus arenarius, containing several full-sized larve. 
Of course I am not able to give any account of their earlier proceedings, but at 
the date above mentioned, they are found feeding in that portion of the plants just 
above the root, where the blades of the grass spring upwards together, overlapping 
each other for about six inches or so, before they begin to diverge or fall apart, and 
assume the glaucous hue above the surface of the sand in which they grow. Nor 
when the larve are full-fed do they change their abode, but spin around them a very 
slight, though tolcrably firm cocoon, with gnawings of their food and particles of 
frass, between two blades. The lower end of the cocoon, which is rather pointed, 
is sometimes mixed with grains of sand; the whole structure in shape being fusi- 
form, and about one inch and a-quarter in length. Several moths emerged on the 
4th of July, at 10 p.m., and made a short flight in my room as soon as their wings 
were dry,—one on the 8th emerged at midnight and was ready for flight in a quarter 
of an hour. 
The full grewn larva is from 1 to 12 inch in length, not very stout, cylindrical, 
and uniform in size except at the second segment, which tapers a little anteriorly, 
the head being still smaller and sometimes retracted into it; the anal segment also 
tapers off to a rounded tip, in size about equal to the head. Its skin is plump and 
smooth, the segmental divisions very moderately incised, and the sub-divisions deli- 
cately defined, the sides dimpled, the head and plate behind it, the anterior legs, 
the anal plate, and the spots, are all very shining, the rest of the body without 
much polish ; it is of a pale, flesh colour, the pulsating dorsal vessel being of a little 
deeper flesh tint ; on each side of this dorsal stripe are just to be discerned, though 
very faintly, four transverse bars of a rather deeper tint of the ground-colour on 
each segment, the broadest being in front; the spiracles are black, and along their 
region the colouring becomes paler, more of a whitish-yellow, as though the interior 
of opaque whiteness showed through the flesh-coloured skin; the head is reddish- 
brown, blackish-brown about the mouth; the plate on the second segment is pale 
yellowish-brown, two pairs of pale, oblong, yellow-brown spots are on the front di- 
vision of the thirteenth segment, and the anal flap is covered with a plate of the 
same colour, having a fringe behind of fine, brown bristles; the tubercular dots of 
the back, and their excessively short bristles, are so very small as to be invisible 
without a powerful lens ; the anterior legs are pale brown, the pro-legs tipped with 
dark brown. 
The pupa varies from five-eighths to three-quarters of an inch in length; is 
rather slender in form, smooth, and shining, and of a light brown colour.—WmM.

Larva of Eupithecia irriquata at Exeter—On June 21st I beat from an oak, 
situated on the border of a beech wood, a small looper, which, by the help of the 
description by C. Dietze, translated in EH. M. M., vol. vii, p. 14, I made almost 
sure belonged to this species, and have since had all doubts removed by the sight 
of two figures, taken by my friend Mr. Buckler, of larvee from which the moths have 
been reared; this is one of the handsomest of our small geometric larve, and it 
seems strange that we have not taken it more frequently.—J. HELLINs, Exeter, 
July 7th, 1871.
