As !i matter of course the Neotn)|iicaI Sjiltiixjiiliii-' are not nnifonuly 

 distributed within the Region, though the greater proportion is found nearly 

 throughout the tropical part pf South and Central America. The comraouest 

 species of which large numbers of individuals seem to occur everywhere are : Heme 

 cinqnlata, Coci/tius duponchel, Protoparce sexta and riistica, Protambiih/.c strigilis, 

 Amph/pterifx gannaaciis, Psi'ix/o.s/t/'/iir tetiio, some Eriniu/ix, Pacliiflia ficus and 

 n;gumeiix, Kjn'sfo/- lin/ahris, Pergf.sa' liDica, Xi/lo////rii/"s pluto, citiroii, and tm-nn. 



The tcmiieratc Soutli of the I'ontinent, wiiich is much poorm' in species and 

 genera than the troi)ii-al districts, is characterised by the s]iecialised genera 

 Neoqciif and Onrlii, which, though jienetratiiig into Ihe Irdpics, do not cxteild 

 very tar northward. Tliere are further in this southern district, which reaches 

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

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

 besides some subspecies. We meet there with I'rotopari-i' hiTi/i, P. turmnana, 

 P. (liffissa pctuniae and diffigsa citffigsa, P. mandiicoides, Hijloicus maiira and 

 justiciae, several Ni/ceri/x, Chlaenogramma iindata, Aleuron prominens, Xijlophanes 

 depuiseti, X. xylohotes, X. schausi, X. pistacina, X. isaon, X. aglaor, Hemeroplanes 

 grisescp.ns, Celerio euphorbia rum, I'liolns satellitia analis, Kmjo japyx discrepam. 



Chili has only two sjiecies of Hawk Moths — Celerio annei and Protoparce 

 sexta caeslri. Ilerse cingidata may also occasionally put in an appearance, 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 sj)ecies of 

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

 species not being of rare occurrence in ('olombia ; Protoparce stuarti, trimacula, 

 scutata, pefuniae, Hyloicus maura, pcsticiae, P/iolus cissi, ohliquus, several Pro- 

 tambuhjx and Ampbjterus, and a number of Xj/lophancs, Ni/ceri/x, Madoryx, 

 etc., have not turned up in Central America ; while Protoparce dilucida, occtdta, 

 ses(jiiiplex, muscosa, corallui^t, liiiniqinosd, croctUu, several IL/loicus, Pliolus 

 tgplion, Ampbjpti'ras donysn and yjiailon, and some Xi/lophanen are not known 

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

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

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

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



The lesser Antilles are rather imperfectly explored. The few species of 

 Sphiiigidac known from there are widesj)read. It is, therefore, the more 

 remarkable that the common Protoparce niatica, which ranges from Argentina 

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

 siil)si)ecies 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 rnstica harterti m\ the lesser Antilles 

 (inclusive of Honaire and ('ura<;ao, but exclusive of Trinidad) is an indication 

 that more sj)ecies may be represented by special races on these islands.
