2274 Insects. 



taken eight specimens; four in the spring and four in August; all off oaks at 

 Lewi sham. 



tenella, Zeller, Linn. Ent. i. 236, f. 30. 

 hortella, Bent. Mus. 



has no dark basal streak, and the apical mark is a line or streak, not a spot. 

 This species I have not met with : one has been taken by Mr. Ellman at Bat- 

 tel (I saw his specimen). 



24. sylvella. Common on maple in May, and sparingly in August. T bred several 



specimens from the leaves of the maple. 



25. comparella. I beat a single specimen out of a hawthorn hedge at Lewisham, on 



the 3rd of May : there was no poplar near. 



26. corylifoliella. I have taken several specimens of this species in May, June and 



August, principally from oaks. 



28. scitella. I beat several specimens from hawthorn, at the end of June and begin- 



ning of July. 



29. spartifoliella. This species swarmed on broom (Spartium scoparium) near 



Airthrey, where I had the pleasure of taking Lithocolletis scopariella, Tri- 

 furcula immundella and Depressaria assimilella, on the 15th and 16th of 

 July. 



30. cerasifoliella. Here again we have two closely allied species confounded, and 



most of the descriptions and figures of the insects are so unsatisfactory, that it 

 is almost impossible to say to which species they belong. The synonymy as 

 corrected will stand thus : — 



suffusella, Zeller, Linn. Ent. iii. 266, PL 2, f. 32. 

 tremulella, Fischer von Koslerstamm. 

 cerasifoliella, Dup. ? 

 unipunctella, St. ? 



Frequents poplars ; has no basal dark lines. Of this species, which I did not 

 previously possess, though I observe it is in most collections, I took a specimen 

 off a Lombardy poplar on the 25th of June, and a second off the same tree on 

 the 17th of September. 



saligna, Z., Linn. Ent. iii. 270. 

 cerasifoliella, Sta. (Zool. 2158), Hub. ? 

 unipunctella, Wood's fig. 1335. 



Frequents willows ; has two dark lines proceeding from the base, and meeting 

 rather beyond the middle of the wing. This is the species I have been in the 

 habit of taking in April ; I have not met with it this year. 



31. Clerckella. Of this species I beat one out of firs at Lewisham, June 15th ; a se- 



cond out of a mixed hedge on the 24th of August ; and a third out of a fir tree 

 at Wickham, on the 30th of August. 



34. Boyerella. Not uncommon at Lewisham, on elms, at the end of May. 



35. cratagifoliclla. Sparingly, at the end of May, on oaks, elm and hawthorn. 



36. Sircomella. This name must sink, the species being described by Zeller under the 



name of ulmella, in the third volume of the ' Linmea Entomologica,' which was
