succeeded by a narrow half fascia from the costa, reaching the lower margin of the 

 cell, where it almost touches the inner edge of a broad median band which is diverted 

 inward to the dorsum below its middle, throwing off a semi-detached fragment also 

 to the dorsum beyond the middle ; a subapical band, slightly sinuate and of irregular 

 width, descends from the costal cilia to the tornus, a line of chestnut and blackish 

 scales descending from the costa half way between this and the median band ; before 

 the apex are two blackish costal spots with some chestnut scales below them, and 

 five inverted groups of chestnut scales are visible along the termen ; a small black 

 spot lies at the end of the cell ; cilia pale cinereous, with a line of mixed blackish 

 and chestnut scales running through them, beyond which they are tessulated with 

 greyish-fuscous — the markings above described are all distinctly separated on the 

 costa (to the number of eight), alternately larger and smaller. JExp. al., 15 mm. 

 Sind-wings rather shining leaden-grey, cilia somewhat paler, with a grey line run- 

 ning through them near their base. Abdomen dark leaden-grey. Legs leaden-grey. 



Type, ^, Mus. Wlsm. 



Hah. : Corsica, Tavignano Valley (Corte). Larva in swellings 

 on shoots of Santolina cliamcecyparissus, V — YI^ excl. 17, X, 1896, one 

 specimen. 



This species is nearly allied to Gochylis pontana, Stgr., Stett. Ent. 

 Ztg., XX, 228 (1859), Stgr. & Wk. Cat., 819, = Gochylis oedemana, 

 Cst., Ann. 8oc. Ent. Fr., LXII, 402—3 (fCocJiylis rujicinctana), PI. 

 XII, 1 (1894), but differs in the absence of a fleshy tint in the ground- 

 colour, in the absence of a basal patch, and in the more streaky 

 appearance of the fore-wings, owing to the presence of narrower 

 markings between the three more conspicuous bands which in pontana 

 are represented only by a few scattered scales, moreover in pontana 

 the subapical band is wider, not sinuate, and not equally attenuate 

 towards the tornus. The cilia of the fore-wings are slightly paler in 

 corsicana, but the hind-wings are decidedly darker throughout. [It 

 should be observed that through an error in numbering the figures on 

 the plate which illustrates M. Constant's paper, oedemana, fig. 1, is 

 called '' rtificinctana , Cst." (laps. cdA. fulvicinctana, Cst., p. 403), while 

 fulvicinctana, fig. 2, is named oedemana, Cst. !] 



The larva of corsicana feeds in May and June in swellings on the 

 shoots of Santolina cliamcdcyparissus. The larvae were very young 

 when collected near Corte on May 21st, and I only succeeded in 

 breeding a single $, which emerged on October 17th. Phalonia 

 pontana (== oedemana), which feed in a similar manner on Artemisia 

 campestris in August and September, pupates after hibernation, the 

 imago appearing in May and June.
