120 Mr. J. Curtis on some new species of British Moths. 
time about rose-trees in my garden at Hayes, the beginning of 
April. 
50. 2. A. Betulatella, Curt. B. E. pl. & fol. 679. The only 
specimens I have seen were taken by Mr. Dale off birch-trees at 
Castle Eden Dene the beginning of August 1837. I have how- 
ever a new species to describe which I shall name 
51. 3. Marcidella, Curt. Cab. It expands 63 lines, and is 
pale rusty-ochre : palpi recurved and tapering ; antenne slender, 
white, and dotted; head and back of thorax whitish : superior 
wings oblong, very much mottled, the costa arched and minutely 
spotted, with a dusky patch just beyond the middle, terminating 
internally in a longitudinal black line ; from the outer angle pro- 
jects obliquely a short brown line, and at the centre of the pos- 
terior margin may be traced an imperfect ring inclosing two or 
three short black streaks on the nervures ; on the i tenior mar- 
gin, before the middle, is a pale conical spot, with a dark margin 
next the base ; cilia fuscous with a dark line at the base and two 
little black lines at the tip, forming one or two white dots; m- 
ferior wings as broad as the superior, very pale mouse-colour, 
apex ovate-lanceolate. 
A pair of this moth was given to me by Mr. Robertson I 
think: the specimens have a worn or faded appearance. 
52. 6. A. granitella, Fischer, has been sent to me by Mr. Dale. 
It is allied to the genus Cer baioia! 
Genus 1088. Gracillaria, Haw.; Curt. Brit. Ent. fol. 479 ; Or- 
nix, Treit. 
53. 1. G. Tazella, Curt. Cab., expands 34 lines, and is si- 
milar to O. Meleagripennella of Hiibner, but the wings are not 
so narrow, and a double white spot near the tip of the costa di- 
stinguishes it. It is white ; the hairs projecting from the fore- 
head are brown : antennz long and dotted : superior wings broad 
towards the apex, fuscous, with a hlac tinge at the extremity ; 
ten white semicrescents ornament the costa, two at the apex 
nearly uniting and inclosing a black dot, which is bounded by 
black and white lines like a feather ; the fringe is white with a 
fine black line ; on the interior margin are two black spots, with 
white ones between them: inferior wings lanceolate and mouse- 
colour : abdomen fuscous spotted with white, the apex tufted in 
the male; the organs of generation bright ochreous : legs white 
and spotted. 
The 2nd June 1839, I beat a few specimens out of yew-trees 
at Micklehanf. 
Genus 1040. Pterophorus, Geoff. ; Curt. Brit. Ent. fol. 161.
