Page. Line. 



149. 8. add Heeger has lately illustrated the transformation of Rhaphium fas- 

 cipes, Sitzungsberichte der Wiener Akademie. ix. (1852). 



165. 31. add pallidicoxa, Roser. Note. Zetterstedt, D. S. p. 4294, has described 

 the male of his D. parvulus, establishing the correctness of the iden- 

 tification in the text. 



167- 34. add pictipennis, Wlbg; Ztt. Note. The female has immaculate wings; 

 see Ztt. D. S. p. 4280. 



175. 18. insert 42*. preetextatus, Hal. N. H. Rev. ii. 63 (1855). 



179. D. aluttfer is better placed in g. Porphyrops, q. v. 



180. 38. add Aphrozeta, Perris, Annales de la Soc. Linn, de Lyon, A. D. 1852. 



186. 15. add semiglaucus, Perris. Occurs also on the sea-coast. (I.) 



187. 1. add cinereus, Perris? 



190. 33. add pictipennis, Bohemann ; Ztt. 



193. 9. Bohemann, Act. Holm. 1851. p. 194 (1853), has described the male, 

 which has the face narrower, the hypopygium small, with slender, fili- 

 form appendages. 



195. 27. add pygmasum, Ztt. D. S. p. 4618 (1855). 



204. 25. add In September, about Blarney Lake. (I.) 



206. 12. The name Machcerium has been long preoccupied in botany, and it does 

 not seem necessary to propose another to replace it, until the genus 

 Rhaphiwm be definitively circumscribed ; with which the species mari- 

 time may well remain united meanwhile. 



212. 42. insert 5*. cretifer, Wlk. C. D. B. M. p. 653 (1849) ; alutifer (Dol.) 

 I. B. D. i. 179. Note. The colour of the tarsi of the male, to which 

 the trivial name alludes, was not noticed in the earlier description. 



214. 20. read Very common. (E. S. I.) 



214. last line, read Not rare on the seacoast. (E. I.) 



214. insert 12. muralis, Mg. Zw. iv. 62. 5 (1824). 



216. last line, add The wings are incumbent in repose, which character alone is suf- 

 ficient to take this group out of the definition of the genus Chrysotus. 



221. 18. insert 1*. celtiber, Hal. N. H. Rev. ii. 63 (1855). 



221. 35. add (I.) 



231. 38. Dahlbohm, Act. Holm. Consp. 1854 (1855), has illustrated the transfor- 

 mation of P. fuscipes. The larva inhabits the body of various Ho- 

 mopterous Hemiptera. 



234. 8. dele Sclerostoma, etc., to end of the line. 



234. 9. for Chetolona read Chetoloxa. 



235. 7. for areolet read areolets. 



237- The genus MALLOTA should have a place here, being represented in the 



British Fauna by M. vittata, Mg. Zw. iii. 378 ; ruddii (Helophilus), 

 Ct. B. E. 429 ; which last has been erroneously cited in the present 

 work as synonymous with Helophilus lunulatus. This correction, 

 supplied by Professor Loew, has been confirmed by the collation of a 

 specimen from Meigen's collection, and ticketed by his own hand, in 

 the possession of Mr. Winuertz. 



240. 13. add viridescens, Vill. iii. 463, 138. 



243. E. fumipennis, as appears from Stephens' Systematic Catalogue, 288, 



g. 122, 10, was not captured nor seen alive by himself. It is probably 

 an American insect, allied to E. vinetorum, Fb., and E. uvarum, Wlk. 



249. 30. for luteo-vittato read nigro-vittato. 



269. Psilota anthracina. No authentic British specimen : represented in Stephens' 

 collection by species of the genus Pipiza. 



298. MeUthreptus. This generic name is preoccupied in ornithology.
