Liune de:scnbed the Papilio Eques Achivus helena in Hyst. NM. ed. x. ji. 4G1. 

 n. 18 (1758) thus :—

We observe that Linn^ enumerates here helena under the " Equites Achivi," 

 which have no red spots at the breast underneath the wings ; all the vellow Troides, 

 exceiit amphrysits, plato, and allies, have, iio\ve\er, the red pectoral spots, and belong, 

 therefore, to the "Equites Trojani." The hdena of 1764, described in Mus. Liid. 

 Ulr., stands indeed under the " Equites Trojani." We see, further, that the initial.s 

 M. L. L'., which always .stand behind the diagnosis of those species which l,inne had 

 seen in the Museum of the (jueen Ludovica Ulrica, are left out. We .see, tliirdly, that 

 Linn^ refers to ^Merian's Insects of Surinam ; I have compared all the editions of that 

 work, and find that in the editions of 1705 and 1717 there are no Troidea figured, but 

 that only on plate 72 of the later editions there is a figiu-e (" jiijara, niaxima ") which 

 lepreseuts unmistakably that species of Troides which is generally known as pompeus 

 (Cramer). This plate 72 does not, however, stand before tiie title-page {" titulo 

 pr((sjixa"), but is the last plate of the work; most probably in the sj)ecimen of 

 Merian's book which Linut^ had before him the last plate, which gives figures of 

 .\frican and Indian animals and has really nothing to do with the remaining te.\t 

 and plates dealing with animals from Surinam, was bound at the beginning of 

 the book. 



If we compare further J>inne's sentence, " Habitat injicn'ibus Arecae Americes" 

 with the text of Merian, " Arborem Arekam . . . non animus est describere; . . . 

 solum hoc loco earn exhibui, ad Erucas et Papiliones, qui sui)er illam proveniunt et 

 gignuntur, demon.strandos. Magna ilia Kruca alimentum ex flokibus petit, ... in 

 Am-eliam mutatur, unde post aliquot dies pulcherrimus Papilio, formosis nigrisque 

 alis supernis, infernis vero aui'eo colons, eruinpit," it is (juite clear —
