As !i niattpi- of course tlie Ncotropiciil Sj,jn)uji(l<tr juv not iniitoniily 

 distributed witliin the Region, though tlie greater ]>n>iioiiion is found nearly 

 throughout the tropical part of South and Central America. The commonest 

 species of which large numbers of individuals seem to occur everywhere are : lli'ise 

 ciiHinlata, Coci/titis duponchel, Protoparce sexta and rustica, Protambah/x afrigiliH, 

 Amplifjjterus gannasdis, Psendosphin-v tetrio, some Erinn.i/is, Panlii/lia Jims and 

 ri'sumeng, Epistor liKjuhris, Pergem Ittsca, Xglophan's pluto, chiron, and tmsa. 



The temjierate South of the Continent, which is much poorer iu species and 

 genera than the tropical districts, is cliaracterised by the s])ccialised genera 

 Neogene and Orecfa, which, tliough penetrating into the tropics, do not extend 

 very far northward. There are further in this southern district, which readies 

 on tlie east coast to Espirito Santo and in the La Plata region to Tucuman 

 and Paraguay, a number of species which have not been found farther north, 

 besides some subspecies. We meet there with I'rotopatec bergi, P. tucunmnn, 

 P. (Htfiss'i petuniae and diffissa (/ij/imi, P. ma>id//ro>des, Hi/loiats mauva and 

 'ptsticiac, several Ni/cergx, Chlaenogramma nKdafa, Alcxron j/roininens, A///ojd//iiii'.s 

 depuiseti, X. xijlohotes, X. scknitsi, X. pistacina, X. isaon, X. aglaor, Hemeroplanes 

 grisescp.ns, Celerio euphorbianim, Pliohis sateUitia analis, Plnyo japijx discri'pans. 



Chili has only two species of Hawk Moths — Celerio (duiri and Protoparce 

 sexta caestri. Ilerse cingulata may also occasionally put in an ap})earance, but 

 is not recorded. 



The discrepancy in the Sphingid fauna of Central and South America, 

 though many of the apparent differences in the comjiosition of the fauna will 

 most likely disappear on further research, is not inconsiderable. No species of 

 Fjiryijlottis has as yet been found in Central America, notwithstanding the 

 species not being of rare occurrence iu Colombia; Prutoparcc st//arti, triniucnla, 

 sautdtft, pctiddae, Ilyloicxs maurd, JHsficiac, Pliolus cissi, obliqit/it<, several Pro- 

 tambtdg.r and Ampli/teriis, and a number of Xi/lophnnrs, Xi/ceri/x, Madori/x, 

 etc., have not turned up in Central America ; while Protoparce dilncida, occulta, 

 KCgq/iiplex, muscosa, coralline, lanuginosa, crocala, several Hijloicus, Pholus 

 fi/phon, Amplgpterus donijsa and ypsHoii, and some Xi/lop'nines are not known 

 from South America. Such differences as these are found everywhere between 

 districts of wide extent, areas differing physiograpliically like the Andes and Brazil 

 being naturally more or less different in the composition of the population, whether 

 there ever has been a geographical barrier or not between the districts. 



The lesser Antilles are rather im])erfectly ex])lored. The few species of 

 Sphirigidae known from there are widespread. It is, therefore, the more 

 remarkable that the common I'mfopan-e nisficu, which ranges from Argentina 

 northward to North America and tln^ larger Antilles, has developed into a 

 subspecies on the lesser Antilles as it has on the Galapagos Islands, while it 

 does not vary geographically on the Continent and on the large West Indian 

 islands. The occurrence of Protoparce rustica harterti on the lesser Antilles 

 (inclusive of Bonaire and Cura9ao, but exclusive of Trinidad) is an indication 

 that more species may be represented by special races on these islands.
