I. — NOTE ON HALO AMP A CHRYSANTHELLUM, PEACH. 

 By ALFEED C. HADDON, M.A., M.E.I. A., Professor of 

 Zoology, Eoyal College of Science, Dublin. 



[Bead, November 18, 1885.] 



AT the corresponding meeting of the Society last year I read a 

 Paper on " A New Species of Halcampa (H. andresii), from 

 Malahide," which was printed in the Proceedings, n. s., vol. iv., 

 pp. 396-398, pi. xvi., figs. 1-4. Since that date I have, through 

 the kindness of my friends Mr. H. W. Jacob and Mr. GK Y. Dixon, 

 seen several specimens of Halcampa from Malahide, and I find 

 that every one has some variation in colour or marking. This 

 fact has led me to reconsider the characters upon which I based 

 the new species just alluded to, and it has resulted in the opinion 

 that it would be wiser to withdraw that name, and to regard our 

 Dublin specimens as the first known Irish examples of H. chry- 

 sanihelhtm, Peach. 



While regretting the fact of introducing what I may term a 

 stillborn synonym (especially when coupled with the name of my 

 friend Professor A. Andres), the figures at all events convey a 

 much better idea of the species than the very unsatisfactory ones 

 on plate vii. in Gosse's Monograph, and so far the Paper is not 

 altogether valueless.
