XII. Notes on Part III. of the Catalogue of British 

 Insects published by the Entomological Society 

 of London ; Hymenoptera [Clnysididn?, Ichneu- 

 monidte, Braconida3, and Evaniidre]. By the 

 Rev. T. A. Marshall, M.A., F.L.S. 



[Read 4tli November, 1872.] 



The compiler liaving willingly complied witli the sugges- 

 tion that no notes should be printed with the Catalogue, 

 desires to make a few remarks upon such points as are not 

 apparent upon the face of the work, and yet ought not to 

 be passed over in silence. The printer's task has been 

 Avell performed, the revision was executed with every care, 

 and no table of errata is now necessary. With the single 

 exception of p. 112, line 7 from top, centaurse (a misprint 

 for centaureae)? it is believed that no erratum exists of a 

 kind likely to mislead the reader. 



With regard to the generic and specific names adopted, 

 and their orthography, very few changes have been ven- 

 tured upon, and those only of an obvious character, care 

 being always taken to observe the law of priority, and in 

 cases of misspelling to preserve as far as possible the iden- 

 tity of the word corrected. The cataloguer has borne in 

 mind that his function was to register the facts observed 

 by others in their own manner, and not to indulge in any 

 originalities. And he has had cause to congi^atulate him- 

 self upon the general correctness of the received names, 

 which compare very favourably with those of some of the 

 other orders of insects. The following are the chief altera- 

 tions Avhich have been adopted: p. 1. Elampns Spin, is 

 corrected by Forster to Ellamjms ; p. 2. Omalus is changed 

 to Ilomalus ; p. 19. Exeplianes to Exoplianes; p. 41. 

 Linoceras Tasch. (1865) is preferred to Macrobatus 

 Holmgr. (1854), because the latter overthrows Graven- 

 horst's original specific name macrobatus, and substitutes 

 clavator Holmgr. ; Brachycentrus is discarded for the 

 same reason, and also because it is preoccupied in Neu- 

 roptera: for this a new name, Cyrtocryptus, was neces- 

 sary ; p. 50. Trachynotas is changed to Nototrachys, to
