cially towards the base. Fore wings with an irregular, 

 incomplete, transverse row of small white wedge-shaped spots 

 nearly across the middle, followed by two more rows, the first 

 consisting of two or three slightly larger, rather squared, 

 white spots, the second of four or five similar but smaller, 

 angular or wedge-shajied, lying across the apical space. There 

 is also a row of indistinct pale dashes near, and parallel with, 

 the hind margin. Hind wings without white spots, but with 

 two parallel transverse rows of indistinctly pale dashes of 

 indications of the white spots beneath. Cilia of all the wings 

 broadly white, broken into squares by blackish dashes. Sexes 

 similar. Under side of the fore wings of the male witli the 

 costa and apical margin white, the former with five dark 

 oblique dashes beyond the middle ; remainder grey-brown, 

 with clear white spots as on the upper side, but much larger 

 and more squared. Hind wings ochreous grey, with three 

 broken rows of white spots, those of the first and second rows 

 large and squared, those of the third small and irregular. 

 Cilia of all the wings very broadly white with blackish dashes 

 as above. Female with the hind wings yellower, the spots 

 of the fore wings elongated into streaks or crescents, and the 

 dashes of the cilia yellowish brown. 



Several specimens were captured in a narrow valley at the 

 edge of a wood in Norfolk by the Rev. T. H. Marsh, at the 

 end of May or beginning of -June, in one season only, in 

 or about the year 1860. These were placed in his collection 

 as S. cdveolms, which, though of larger size, they sufficiently 

 resemble, and of which he had no other specimens. Here I 

 found them when looking through the collection about three 

 years ago, and ultimately ascertained to what species they 

 belonged, though with considerable difiiculty, owing to their 

 differing slightly from all the recognised species in this very 

 close and difficult group, and apparently forming a link 

 between >S'. alveus and S. serratulw. This is probably to be 

 explained, satisfactorily, by the fact that some authors con- 

 sider ;S'. serrahdw to be simply a variety of the other.
