of the Genus Hemerobws of Linncsiis, <^^c. 57 



I avail myself of this opportunity to add that the species figured 

 in the " British Entomology" (pi. 202), under the name oi" H.fim- 

 hrialus, is the H. hirlus of Linnaeus ; and the H. crispus of SchaefTer 

 appeal's to be the //. angulaius of Stephens and the //. Ilopii of 

 Dale's MSS. This last rare species Mr. Dale has taken at Lynd- 

 hurst the 15th April, 1830; and subsequently, June 27th, on hazel, 

 in Caundle Holts, Dorset, where I also captured another specimen 

 the 13th July, 181G. 



As the settlement of nomenclature is daily becoming more ne- 

 cessary, being of the greatest consequence to science in every 

 point of view, no opportunity should be omitted of correcting 

 oversights. To the credit of France, every disposition is now 

 shown to ascertain the correct and original names of species, and 

 the same course is pursued in a measure in this country, but not 

 with the care and impartiality I fear which is required. I will not 

 now enter upon the subject to any extent, as it would lead me to 

 a great length. I will merely state, 1st. That men of science, 

 living in different countries and even in the same kingdom, cannot 

 understand each other, from the differences in nomenclature as it 

 now exists ; 2ndly. That the pages of every work on species are 

 complicated and wasted with synonyms ; and 3rdly. That the most 

 elaborate and careful memoranda of dates and localities are ren- 

 dered doubtful or worthless from an unstable nomenclature. 



Nomenclature of Coniopteryx. 



On referring to one of the lists of the British Museum, to com- 

 pare the Hemerobii, I regret to see that some names are changed 

 which must be restored, amongst them Coniopteryx is changed for 

 Coniortes, which renders it necessary for me to say a few words 

 in order to restore the authorized name. The facts are these : — 

 Early in 1834, Mr. Haliday sent me drawings of a larva which he 

 believed to be that of the genus which I wished to publish, and 

 proposed to call Coniopteryx. It would have appeared at once, 

 but Mr. Haliday wished me to delay the publication until he had 

 made farther researches, so that it was not actually published until 

 the end of November. It is reported in the " Proceedings" of this 

 Society, that, on July 7th, 1834, a communication was read "On 

 Coniortes, a new British Genus o^ Neuroptcra, belonging to the^e- 

 merobidce" by J. O. Westwood, F.L.S., &c. ; but had not the Secre- 

 tary of the day appended a note at the foot of the page, no one 

 unconnected with the Entomological Society could have known 

 what Coniortes was, in the absence of any description. The note 

 referred to states, that " Since this Memoir was read, this genus has
