identical in time of publication with Anceryx, I do so because 

 Burmeister's genus is more limited in extent and is conceived in 

 the sense in which I employ it. Hubner's genus Phlegethontius is 

 equivalent to Macrosila as used by Dr. Clemens ; the type of the 

 latter seems different and the older name is used for properly as- 

 sociated species. 



When we compare our fauna with that of Europe, we find 

 that it is twice as numerous in species — 91 to 40. Ours con- 

 tains no true Macroglosste of the type of Stellatarum, and no 

 species of Achcrontia, though loose writers such as Maasen 

 have credited Mexico with a species of the latter genus. 



In the European genus Deilephila we are poor, having but 

 two, representative of two European species, Livornica and 

 Galit, but apparently sufficiently distinct. In the clear-winged 

 Macroglossse, belonging to Heniaris (and its subgenus Hcmno- 

 rrJiagid) we have many forms against two in Europe. In the 

 typical Sphinges, genus Sphinx {^Lethia)^ of which Ltgustri is 

 typical while Convohuli is to be referred to PhlcgetJiontius, we are 

 rich in closely allied species against one in Europe, We have at 

 least one true Smcrmtlms from California, congeneric with the 

 European Ocellata. Our species from the East diverge from this 

 type and resemble the species Kindei'manni of Lederer from Asia 

 Minor; again we have in Versicolor a representative of the genus 

 Ampelophaga, also from Eastern Asia. In Calasymbolus, Paonias 

 and Cressonia we have three American structural types of 

 Smerifithi, while Triptogon has a great number of Eastern 

 Asiatic species, hardly more than races, so near do they run 

 together. 



Our fauna comes mainly from the South, whence we receive 

 the Choerocampid forms. PacJiylia, and perhaps Argeus, may 

 breed in Florida and Southern Texas. The specimens taken oc- 

 casionally on the coast and up the valley of the Mississippi are 

 probably immigrants from the West Indies or Mexico. The 3Ian- 

 diiccB come to us largely from the South, and Phlegethontius is 

 more numerously represented in South America. Amphonyx 

 AnteBus may be only an occasional visitant at Key West ; the 

 genus is West Indian and South American. 



From Western and Northern Asia we receive Hemaris, Dei- 

 lephila, Svierinthus, Triptogon, Hyloiciis^ and Sphinx, though the 

 development of the latter genus is North American. From the 

 South we receive Aellopos, Caniethia, Aviphion, Enyo, Philampe- 

 liis, Argeus, Pachylia, Darenima, Dilndia, Amphonyx, Phlegethon- 

 tius and Dilophonota. With Eastern Asia we have Ejtsinerin- 

 thus and Ampelophaga in common. Genera peculiar to our 

 fauna are Lepisesia, Euproserpinus, Thyreus, Deidaniia, Arctonotus, 

 Everyx, Paonias, Ccdasymbobis, Cressonia, Ceratomia, Dolba, 

 Ellema, Exedrium; as a rule, genera containing single, compara-
