( { )/((t(/rii/ (/i(/.:n/i/fi Grote, must both be known before it can 

 be placed with certainty. According to my friend Mr. Robert 

 Bunker, ('itlifrnnid rct/a/ix comes occasionally to bait alter 

 the fashion of a SjJtinx. The resemblance between the 

 American genera TiY/r/r.v and Ct'ratoiu'm is pointed out by me 

 in 1865. I bring Triptoffoit and Cfntfomia- together from 

 the thoracic "horns'' of the larvae, resembling each other 

 and this Bombycid genus. I have thus two points to excuse 

 my arrangement of the Xnn'rhithint'. viz: the resemblance 

 between AnibultfX and Calasymbolus at one end and Trij>f<>(/t/ 

 and CiTfitoniia at the other. It is the young stages which 

 must afford us a guide in our deductions and, already in 1865, 

 I have seen the importance of evidence which leads me to 

 insist upon my classification of the ^>lihnjl<]ne today and 

 the longer they are studied. As to the importance of .studying 

 American forms there can be no question if, as I believe, 

 older types exist here than elsewhere. Just as I believe 

 the species of Batikn-cliid to be recentl}" separated, I look 

 upon the Paleohesperidae as relics of a very old and else 

 obsolete type of the Lepidoptera. In the question of the 

 relationship of the Sphingidae and the B<iil>i/n>*, the "horn" 

 of Bnnili/x in or i must be remembered, no less than the 

 distention of the anterior segments of this larva which recalls 

 the Elephant Hawk Moths. While I think there can be 

 no doubt that the membranous tongue in the Kntcrintlihun' 

 is a retained character, the question is not so clear with 

 Ellciua, in which the character may be one of reversion. 



The characters of the Family Paleohesperidae (consult 

 my paper, Can. Ent. 173, for the year 1875. where they 

 are first announced) are as follows : Eyes large and naked. 

 No ocelli ; caputal squamation mixed flattened scales and 

 hair. Antennae capitate, without terminal inflection. Wings 

 heavy, entire. Tibiae and tarsi strongly spinose; hind and 

 middle tibiae with terminal claws. Legs stout. The three 

 parts of the body unusually distinct. Form cylindrical. Head 

 broad in front. Ornamentation much like the 7/rx^r/Vm . 

 brown and yellow. The characters by which this Family 

 is separated from the other Butterflies, are taken from the
