1870.) 1531! 
The stigmata indicated by darker grey markings. Second line denticu- 
late, nearly parallel with the hind margin. Sub-terminal line very 
wavy and faintly visible on the paler ground colour. Hind margin 
dotted with dark grey. Cilia pale grey. 
Hind-wings silky-white, narrowly bordered with fuscous. 
I am at present aware of the occurrence of three specimens only. 
One taken in London, by Mr. Henry Pryer, of Tooley Street, on the 
27th August last, a second by myself on the 10th September last, and 
the other, captured some years ago by Mr. T. Eedles, and in the collec- 
tion of Mr. Stainton. 
I have named this species in honour of Mr. Pryer. 
HOM@OSOMA SENECIONIS, 2. sp. 
Alar expanse, 8 to 9 lines. In general appearance, this species 
resembles its congeners nebulella and binevella. 
Head, thorax, and abdomen, greyish. 
Fore-wings: ground colour shining greyish-white, the inner half 
being suffused with a warm, fuscous tint. There are no indications of 
a first line. About the junction of the middle with the inner third, 
and towards the middle of the wing are two, and in some cases three, 
dark dashes. At about the junction of the middle with the outer 
third are two distinct black dots. Beyond these dots is the second 
line, which affords a most distinctive character to the species; it is 
straight, and composed of black dots running in a direction oblique to 
the hind margin. The hind margin is more or less distinctly dotted. 
Cilia grey, with a faint fuscous tint. 
Hind wings shining grey, cilia paler. 
From H. nebulella, to which this species is nearly allied, it is at 
once distinguished by its much smaller size. From H. binevella, the 
straightly oblique dotted second line, independently of other characters, 
readily separates it. 
The following careful description of the larva of this species has 
been kindly forwarded to me by Mr. Buckler: 
“T received on June 19th, from Mr. Howard Vaughan, three larve 
“mining in stems of rag-wort (Senecio jacobea), and pushing out little 
“heaps of frass which are agglomerated together by webs. 
“ When full-grown, the larva is half-an-inch long, plump, tapering 
“towards the head, which is a little smaller than the second segment. 
‘Segments well defined, and each (excepting the thoracic) sub-divided 
“by only one deep wrinkle. The spiracular region a little puffed.
