pascuana, Hiib., Wilk. (erroneously spelt pasivatia, Hiib., 99, but 

 corrected in a subsequent work— Verzeicbniss bekannter Scbmetter- 

 linge). — Fore-wing 4:^ lines by 11, rather long and oval, the margins 

 being curved and much rounded off. Rather a smooth and greasy 

 looking insect, with its markings much obscured by grey scales. 

 Easily distinguished from all the other species in the genus by the 

 very considerable over-lapping of its wings when in repose, and its 

 consequent appearance of narrotvness. It is very plentiful indeed at 

 Brandon, and found in many parts of the country, but usually con- 

 founded with viiyaureana, from which the over-lapping wings readily 

 distinguish it. 



Mr. W. R. Jeffrey, of Ashford, describes the larva as yellowish- 

 grey with black spots, feeding on flowers of Si/pochceris radicata and 

 Anfhemis arvensis. 



Dr. Wood, of Tarrington, and Mr. W. Thompson, of Stony 

 Stratford, have reared it from Chrysanthemu7n leucanthemum. My own 

 efforts to rear it have, so far, been unsuccessful. 



Among the examples of Tortrices sent me by Professor Zeller some 

 years ago, are several specimens of a peculiar grey-brown — almost 

 yellowish-brown — Sciaphila, labelled '''pascuana, F. v. R." These 

 seem to be very close to, if not identical with, a pale greyish-brown, or 

 yellowish-brown, Sciaphila, which is found in plenty in salt marshes 

 in the south of England, and particularly on both sides of the mouth 

 of the Thames. This form seems pretty constant in size and colour, 

 and, in absence of markings, but it also corresponds so very accurately 

 in size and shape with pascuana, Hiib., that there seems little proba- 

 bility that they are really distinct. The markings, when visible, also 

 agree closely with those of the latter. 



I am indebted to Messrs. Sydney Webb and Howard Yaughan 

 for specimens. Mr. Webb has reared one specimen (accidentally) 

 from Aster tripoUum. This variety appears to be plentiful in the 

 drier parts of the salt marshes, and scarcely to be known elsewhere. 

 It was, I believe, first noticed there by Mr. S. Stevens many years ago. 

 Mr. AV^ebb says that it emerges in June and July, and continues out 

 a long time. In colour, it shows a remarkable divergence from typical 

 pascuana and the remainder of the genus, leaning strongly towards 

 that of 8. ictericana. 



conspersana, Dougl., Wilk. {perterana, Gn., MS.). — Fore-wing 



5 lines by If, long and narrow, with the costa straight beyond tho 



middle, apex somewhat pointed, and hind-wings oblique.
