30 TORTRICINA. 



base is suffused with dark fuscous, leaving a pale mark at the costa, 

 with others on the dorsal margin. The posterior edge of the basal 

 patch and anterior border of the fascia are bounded by cream-coloured 

 streaks. Within the anal angle is an elongated, speckled, black 

 mark, and immediately above it is a small clouded black spot. The 

 costa is broadly marked with triangular brown patches, three of 

 which are beyond the central fascia, followed by the apical spot, of 

 rich brown colour, which is produced down the apical margin ; below 

 the apical spot is a dusky cloud, sometimes black ; the middle of the 

 apical region is more or less mottled with black spots on a grey 

 ground. Apical scales intense brown, with the bases and tips nar- 

 rowly cream- colour. Cilia shining, rich brown, slightly mottled, 

 and, with the apical scales, becoming cream-colour at the anal angle. 

 Posterior wings white at the base, with a pearly lustre, gradually 

 becoming fuscous to the margins ; darkest at the apex. Marginal 

 scales fuscous. Cilia pale fuscous grey at the apex, straw-colour at 

 the anal angle. Abdomen fuscous, the caudal tuft shining drab.

 the posterior wings are wholly rich fuscous, slightly paler at the 

 base. 



A rare species, and net variable. In general appearance it 

 approaches A. Gentianana, but is much smaller, and the light 

 portions of the anterior wings paler. The pale- bordered pos- 

 terior wings of the 3 are an excellent character. 



The imago appears in May and June, sparingly in the southern 

 counties, as well as in the north of England. Stephens records 

 Coombe and Darenth Woods as localities ; at the latter, specimens 

 were taken in July. Mr. Staintou, in the ' Zoologist/ p. 1791, 

 states that he took one specimen in a clover-field at Pashley, near 

 Ticehurst in Sussex, in September. By this range of season 

 (May to September) it seems that this insect is continually ap- 

 pearing, or that there may be more than one brood in the year. 



According to Guenee, the larva feeds on the pith of the Teazle 

 (Dipsacus), frequently living and undergoing its transformations 

 under a silken covering among the seeds. It is reddish white, 

 with the head, shield and true legs black. In shape vermi- 

 form, and small in size.
