 upon Myrica ijalc (Pears) .

Note on the larva of Glyphipteryx fuscoviridella. — On June 

 Ith, 1898, 1 saw four imagines of this common species round a patch 

 of Luznla campeMris, in a meadow here. It struck me then, consider- 

 ing the known food-plants of other species of the genus Glyphipteryx, 

 that Ltizida 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 Licida cainpestris, 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-AVork cocoon. On April 18th I searched again and 

 found a third larva, head downwards, in a stem of Lnznla. 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 Lmula, 

 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 Glypldpteryx fuscoviridella. The following 

 description of the larva Avas made : 



The larva is stout and fairly cylindrical in section. The head is very small. 

 The body gradually increases 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 1st 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 larvae. The chief causes why 

 the larva of this species has hitherto remained undetected appear to
