AMERICAN LEPIDOPTERA. 13 



pears in Pheosia. Melanopha Hiib., Tentamen, replaces Iclithyura 

 Hiib., Verzeichniss, and under that name our species are listed. 

 Pallet is given specific rank, and so is indentata, else no change is 

 made in our species. Apicalis is credited to Walker instead of to 

 Barnston, and Mr. Kirby has consistently so credited all the species 

 described by Walker from Barnston's catalogue names; correctly so 

 in my opinion. In Datana, genus 153, no change is made, and the 

 genus contains our species only. Nadata contains three species beside 

 those from our fauna ; all Asiatic. No American s])ecies of Nydalea 

 appeai-s, though Mr. Grote has described an N. uuliance referring it 

 to the Noctuidse near Cacullla. From a casual examination of the 

 type it is much nearer to Bombycia. As an ending to the family 

 there appear 23 genera described by Walker, all save one with a 

 single species only, and all either from Brazil or Sarawak. Whether 

 they are all so intimately related, or whether Mr. Kirby found it 

 impossible to place them more definitely does not appear. 



As Family XXI, appear the Sphingidse sandwiched in between 

 the Notodontidse and Bombycidse. This is quite out of the accepted 

 course, but I am not prepared to say that it is indefensible. The 

 question of arrangement oflfers so many opportunities for individual 

 judgment, as it is universally admitted that no linear arrangement 

 can truly express all relationships, that almost any arrangement can 

 be defended ; six subfamilies with 116 genera are recognized. At 

 the head come Macroglossinpe with Hemaris Dalm. as first genus. 

 All our species are included under this term and nearly all the 

 names are given specific rank. As to some of the forms where the 

 synonymy is in dispute, this course was perhaps the safest, but in 

 other cases I do not understand why Mr. Kirby ignored the conclu- 

 sions reached in my monograph of the American species. Under 

 Lepisesia only Jiavofasciata and ulaluine are included. I have shown 

 that it is much wider in its application in our fauna. Under Aello- 

 pos, neither tantalus nor fadus are credited to our fauna. Euproser- 

 pinus is used hv phaeton and euterpe, and Dieneces Butlei- for elarkice 

 and circce. AVhy eight genera, quite different in structural charac- 

 ters, should be placed between these genera and Lephesia, is a mvs- 

 tery to me. Under Perigonia we find tacita Druce, fj-om the United 

 States. It is unknown to me. Thyreus is marked preoccupied, and 

 Spjhecodina Blanch, is used instead, with abbotti as type. Amphion 

 nessus and Deidamia inseriptum are both monotypic from our fauna. 

 Gauroe and Jua,nita appear in Pterogon. I have shown that the
