call attention to one or two oversights, and if I am wrong, no doubt Mr. 

 Smith will convince me of the error of my ways. 



( >ur author lias taken Pogocolon and made Lepisesia, and Euproserp- 

 inus synonyms of the same. Without discussing the question whether 

 they are really synonymous, 1 would merely say that Lepisesia was estab- 

 lished by (dote in Aug. 1865. Euproserpinus by Grote and Robinson in 

 Nov. 1865, and Pogocolon by Boisduval in 1874, so that Lepisesia should 

 have been used. 



The genus Darapsa was established by Walker in 1856 but Mr. 

 Butler states in his "Revision", that the "genus was founded upon most 

 heterogeneous material, the first three species [choerilus Cr., myron Cr. and 

 pholusCx. J being referable to Hiibner's genus O/us, the fifth, to Walker's 

 genus Diodosida, the sixth and eighth, to the genus Daphnis Of Hiibner, 

 the seventh, ninth and tenth, to Chderocampa of Duponchel; there there- 

 fore remains only the fourth species, allied to Charocampa, but apparently 

 sufficiently distinct". This is rhodocera from the West Indies and is 

 retained by Butler under the genus Darapsa as the type. The genus 

 O/us was proposed by Hiibner for choerilus and myron and is used for 

 these species and some others by Mr. Butler. Mr. Grote had previously 

 broken up Walker's genus in the same manner but in 1873 ' ie changed 

 his ideas, for some reason not apparent, and took Walker's first species 

 {choerilus) for the tvpe and adopted the genus Darapsa for our species. 

 Mr. Butler objected to this as the genus thus limited was synonymous 

 with Hiibner's O/us. But the name O/us had been previously used by 

 Cuvier for a genus of birds which prevents our using it for insects and on 

 account ol this, Boisduval in 1874, established the genus Everyx with 

 myron for the type. If rhodocera should prove to be really congeneric 

 with myron and choerilus, then Walker's Darapsa should be used for 

 them all. but Mr. Smith who has examined rhodocera, informs me that it 

 is really generically distinct and therefore 1 see no alternative but to use 

 Everyx for our species. 



In 1873, Mr. Grote established his genus Calasymbolus with as/ylus 

 lor the tvpe. leaving myops with exececaius under Paonias, but later he 

 transferred myops to Calasymbolus. The only characters given were "the 

 genus differs from Paonias in the shape ol the secondaries, and from 

 Smerinihui in antenna! structure". With regard to the antennal struct- 

 ure, Mr. (dote probably compared the male of as/ylus, having biciliate 

 antennae, with the male of gemina/us which has strongly bipectinated 

 antennas while in cerisii they are biciliate Exccecatus, myops and as/ylus 

 all agree in the form of the costa of the hind wings, in the small size of 

 the thorax, the unsunken head and the vestiture of the head and thorax, 

 and in these regards they differ from gemina/us and cerisii. On the other
