NECESSARY RESTITUTION OF THE NAMES GIVEN 

 BY TH. W. HARRIS TO TWO NORTH AMERICAN 

 SPHINGIDy^. 



By Dr. H. A. Hagen. 



The arrangement of the biological collection of the Lepidop- 

 tera obliged me to compare carefully the literature to ascertain 

 which names I have to adopt. It seems to me that among the 

 Sphingids two North American species, first described by Th. W. 

 Harris, should retain his names. Ceratoniia qiiadricornis, de- 

 scribed 1839, 1'^'^^ been changed to C. aiiiyntor, Hubn. This 

 species is figured by Huebner Samml. exot. Schm. Vol. III. (not 

 Vol. II,, as it is quoted by Messrs. Grote and Robinson, p. 16, 

 which error is repeated by Mr. A. G. Butler, Sphingida;, p. 621). 

 The date of the plate containing '' Agrius Ainyntor , Pennsylvania," 

 is not sure, but certainly later than, as quoted by Messrs. Grote and 

 Robinson, 1806-1824, and by Mr. Butler, 1806. This plate is No. 

 46 (numbered by pencil) in the copy of Vol. III. of the Harvard 

 Coll. Library of the fifty-three plates forming the whole volume 

 here and in von Heyden's Library in Frankfort o. M., Europe. 

 Geyer's Necrolog. of Huebner, in Thou's Archiv F. I, p. 30, states, 

 July I, 1827, that the Samml. exot. Schmetterl. contains 439 plates. 

 These plates form Vol. I. and Vol. II., but the copy before me, 

 and others compared in Europe, contain only 438. Geyer states 

 further that he has decided to continue the publication of Hueb- 

 ner's works ; but in 1827, the plate with A. Auiyntor had not 

 appeared. Further, on the original wrapper (in the library in 

 Berlin) Sammlung Europ. Schmetterl., Horda, Vol. VII., 1834, 

 Mr. Geyer states that for the Vol. III., Samml. exot. Schmett. 

 " are now ready thirty-one plates." As A. Amyntor is plate 

 forty-six, it is published only after 1834, and in any way is not 

 Amyntor of Huebner, but of Geyer. Perhaps it may even not 

 antedate Harris. 



It is a rule, everywhere accepted, that a figure even named 

 can never antedate a description. Therefore, Mr. Harris, who 

 knew that the copy in Harvard Library arrived here July 20, 1849, 

 has, in a cop)^ of the catalogue of N. A. Sph., presented to Prof. 



* In mv paper on the American form of P. Machaon, in this ^Magazine for May, 1882, I stated 

 that the bl.ick pjrtb in var. Aliaska were more intensely colored, etc., than the old world types, but I 

 made an exception m tavor of the Himalayan, saying ot these, they " resemble the American in this 

 respect." Dr. Hagen says of my statemnt, p. 157, that it " is not true." " The large material before 

 me proves this statement y(;r ^/ic Hhitaiayan specimens, and even for some European ones, to be in- 

 correct." The Doctor misapprehended me.
