44 THE ENTOMOLOGIST. 



conspicuous larvae are full-fed they may be observed 

 crawling down the trunks in order to undergo pupation, 

 which takes place in a web on the surface of the ground, 

 amongst frillen leaves, under loose bark, &c. : the perfect 

 insect does not appear until the following June, generally 

 between the 8th and 23rd, when it may occasionally be found 

 resting on the trunks of the sycamores. I am indebted to 

 Mr. Blackmore for the specimen described, and have fre- 

 quently found others myself — Edward Newman. 



Description of the Larva of Triphcena orhona. — Egg 

 laid in July, on a variety of low plants, on which the young 

 larva feeds; one of these very commonly selected is Stellaria 

 media (common chick weed) : they are hatched in August, 

 and hybernate early : as soon as the buds of the sallow 

 and whitethorn open they ascend the stems and feed on 

 the young leaves : the larva is full fed in May, when it 

 rolls into a compact ring if disturbed. Head, when moving, 

 porrected, rather narrower than the body : body velvety, 

 nearly uniforndy cylindrical, but increasing almost imper- 

 ceptibly to the 12th segment, which is the largest. Colour 

 of head and body dingy umber-brown, the head slightly 

 variegated with darker shades of the same colour; the dorsal 

 region of the body is uniformly brown ; the anterior segments 

 from the 2nd to the 5th, both inclusive, interrupted by a me- 

 dian very narrow and very indistinct line ; the 11th and 12lh 

 segments have each two very conspicuous velvety dorsal 

 markings almost black; on the lllh segment these are dis- 

 tant, narrow, longitudinal and waved; those on the 12th seg- 

 ment are decidedly more aj^proximate, broader and larger ; 

 their figure is irregular, but their anterior extremity is pointed, 

 the posterior exlrennty square ; the spiracles are white, and 

 are situated at the extreme edge of the brown dorsal area ; 

 beneath them is a broad pale wainscot-coloured stripe ex- 

 tending the entire length of the larva, and this, from the 2ud 

 to the 7th segment, is tinged along the middle with brick- 

 red ; the belly is smoky brown, and the legs and claspers are 

 of the same colour. Changes to a smooth brown chrysalis 

 on the surface of the earth : the imago usually appears 

 about the 1st of July, and specimens continue to emerge 

 throufj,hout the whole of July and August. I am indebted to 

 Mr. Thomas Huckett for specimens of this larva. — Id.
