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. pi. & 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 6^ lines, and is 

 pale rusty-ochre : palpi recurved and tapering ; antennae 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 interior 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 : in- 

 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 Cerostoma. 



Genus 1038. Gracillaria, Haw. ; Curt. Brit. Ent. fol. 479 ; Or- 

 nix, Treit. 



53. 1. G. Taxella, Curt. Cab., expands 3^ 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 : antennae long and dotted : superior wings broad 

 towards the apex, fuscous, with a lilac 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 Mickleham. 



Genus J 040. Pterophorus, Geoff. ; Curt. Brit. Ent. fol. 161.
