3. P.fusco-anea, Haw., is twice as large as the foregoing spe- 

 cies. I have met with it the middle of August on the Downs 

 near Lul worth, and also at Mickleham. 



37. Genus 1023. Microsetia, Step. 



4. M. sericiella, Haw. I found this little moth in abundance 

 on the flowers of Euphorbia amygdaloides in Grovely Wood, near 

 Wilton, the 9th May 1842. 



Genus 1025. Argyromyges, Curt. Brit. Ent. fol. 284. 



38. 1. A. Autumnella, Curt. B. E. pi. 284. This species is 

 now decided to be the T. Clerckella of Linnseus, and the A. 

 Clerckella of our cabinets is called scitella. 



39. l b . A. Acerfoliella, Curt. ; Padifoliella, Stain. The male 

 expands 4 lines, and the antennae are longer than the wings : it is 

 sickly-white, superior wings very narrow, falcate, fuscous with a 

 pure white stripe along the interior margin, surrounding a long 

 oblique curved line at the anal angle ; the apex attenuated, in- 

 curved, spotted black and white with a very black dot at the tip : 

 inferior wings very narrow, smoky as well as the long cilia. The 

 female is near 5 lines in expanse, fuscous ; head and thorax white : 



superior wings very narrow, less falcate than in the male and 

 terminating like a feather, rich brown, the interior margin pure 

 white with the inner edge irregular, forming a square near the 

 base, an oblique lobe at the middle, and a loop at the ana] angle, 

 inclosing a brown spot ; the cilia of the apex is white with black 

 crescents on the extremity of the costa and round the tip, where 

 there is a black dot : inferior wings very narrow and tapering to 

 a point. 



For a pair of this rarity I am indebted to Mr. T. Desvignes, 

 who took several in September and October flying out of maples 

 and whitethorns in Whittlebury Forest. The sexes seem to vary 

 considerably, but neither of them agrees with Hiibner's figure of 

 T. Padifoliella, pi. 46. f. 316, in which the costa is white and the 

 interior margin spotted dark, whereas in our species it is exactly 

 the reverse. 



40. 16. A. hortella, Fab., I took in a plantation near Wands- 

 worth the 19th of May. 



41. 21. A. Cydoniella, Step., is the lautella of Heyden. I 

 found a beautiful specimen in Mullens Copse at Glanville'sWoot- 

 ton the 18th May 1842. 



42. 6 b . A. maritima, Stain. MS. The 26th of August, 1836, 

 I first discovered this species on the banks of the river by St. 

 Vincent's Rocks. It was tolerably plentiful. 



43. 7. A. obscurella, Step. 111. iv. 259. This insect occurs
