188 Mr. H. T. Stainton on Gracilaria, 



Posterior wings rather broad, brown-grey, with paler cilia. 



Pretty generally distributed throughout the country, and not 

 uncommon, but easily overlooked from its small size and dark 

 colour. It occurs in many parts of the Continent. 



The larva feeds in June and October on the Hypericum per- 

 foratum ; when very young, it mines the leaves (PI. XV. fig. 4 a), 

 but afterwards it rolls them up into a form resembling two short 

 cones (PI. XV. fig. 4 6), united by their bases : in these rolled 

 up leaves it feeds on the inner epidermis, thus discolouring the 

 cones, which soon assume a rust coloured appearance. The 

 larva, which has six legs and eight prolegs, is very pale yel- 

 lowish ; the head is slightly darker, and a darker middle streak 

 is faintly indicated along the back. Unlike Phasianipennella, the 

 larva of this species does not undergo its transformation inside 

 the cone, but when full grown it leaves the cone and proceeds to 

 another leaf, which it rolls up longitudinally in the form of a 

 cigar (PI. XV. fig. 4 c), and then, spinning a white cocoon, turns 

 to a brown pupa. The period for collecting the pupae is the 

 beginning of July, and from the end of October to April. The 

 perfect insect appears in April and May, and in July and August. 



The Gracilaria plumbclla, figured by Duponchel, Supp., pi. 89, 

 fig. 13, is not improbably intended for this species. 



The oldest name applied to this insect is undoubtedly Stipella, 

 Haworth ; but as in Haworth's description the first spot on the 

 inner margin is entirely omitted, and the description is only ex- 

 plained by his " exemplarium unicum" being in the possession of 

 the Entomological Society, I have not thought it desirable to 

 retain this name. 



Sp. 20. Quadruplella, Zeller. (PI. XV. fig. 5.) 



Alis anticis nitidulis fuscis, guttis quatuor oblongis obliquis 

 sulphureis alternatim oppositis ; pectore sulphureo-maculato. 



Quadruplella, Z. Isis, 1839, S. 209 ; Linn. Ent. ii. 355. 

 Auroguttella, Steph. Illust. iv. 363. 



Allied to the preceding, and also to Quadrisignella ; from Auro- 

 guttella it is distinguished by the sulphur yellow (not golden 

 yellow) spots being very sharply defined, the first costal spot 

 touches the costa, and the first dorsal spot is not continued to the 

 base ; Quadrisignella, which it resembles in the two last parti- 

 culars, has the spots broad and placed nearly perpendicularly to 

 the margins, whereas in Quadruplella the spots are narrow, and 

 placed obliquely to the margins. 



Expansion of the wings 4 — 5 lines.
