NotE ON THE LARVA OF GLYPHIPTERYX FUSCOVIRIDELLA.—On June 
4th, 1898, I saw four imagines of this common species round a patch 
of Luzula campestris, in a meadow here. It struck me then, consider- 
ing the known food-plants of other species of the genus Glyphipterya, 
that Luzula would be a very likely food-plant for G. fuscoviridella. 
On April 14th, 1900, I noticed that many of the young leaves in the 
patches of Luzula campestris, in the same meadow, were quite brown. 
On digging up some of the plants I found the stems bearing brown 
leaves had been attacked by some internal feeding larva. One stem, 
with partially brown leaves, when split open, disclosed a stout whitish 
larva, resting head upwards in the interior. Among the roots of a 
neighbouring stem I found another similar larva, already surrounded 
by an open net-work cocoon. On April 18th I searched again and 
found a third larva, head downwards, in a stem of Luzula. The first 
larva pupated without forming any cocoon, and is now, I fear, dead. 
The third larva, after living some days out of sight among Luzula, 
planted in a flower pot, came to the surface, and was subsequently 
attacked by mould. The larva in the cocoon had pupated when I 
again looked at it on April 17th. Exactly four weeks afterwards it 
produced a fine imago of Glyphipteryx fuscoviridella. The following 
description of the larva was made : 
The larva is stout and fairly cylindrical in section. The head is very small. 
The body gradually ineveases in bulk, to the 3rd or 4th abdominal segments, when 
it somewhat abruptly decreases to the 9th abdominal. The colour of the head is 
pale shining amber, that of the body very pale ochreous, becoming pinkish-brown 
on the dorsal area. The usual tubercles are small, but furnished with a stout 
bristle. The legs are whitish, banded with ochreous, and the weak prolegs very 
pale ochreous. The spiracles are black, connected by a thin smoke-coloured line. 
The plate on the Ist thoracic segment is large and pale ochreous. The 8th 
abdominal segment has three blackish horny dorsal spots, the central one of which 
is transversely elongated. The 9th abdominal is armed anteriorly with a dark 
horny ochreous dorsal band, and a very strong dark ochreous suranal plate with 
central depression, and four or more points each bearing a bristle. 
There can be no doubt, I think, that the larva of this species feeds, 
at least in the spring, on the inner pith of the young shoots of Luzula 
campestris. Probably it also attacks L. pilosa. The end of March 
would be the best time to search for the larve. The chief causes why 
the larva of this species has hitherto remained undetected appear to
