Calas)/mhob/!< was originally pvoposeil for astylus, but. lat(^r on employed by 

 Bntler and also by Grote himself for nearly all the American eyed Hawk Moths. 



Grote's subgenus Copismerinthus has no justification whatever. When the 

 author learned from Fernald's Sphingidae of New England that cerisj/i had the 

 foretibia armed at the end with a claw or thorn, he thought this to be something 

 ([uite characteristic, not being aware that the European ordlnta, which he considered 

 the type of Smei-inthiis, possessed the same armature. In the same paper Grote 

 states, as he had done in previous articles, that ophthalmicus from California is, in 

 America, the onl}' representative of the t3'pical genus Smerinthus. This ophthalmic it^ 

 is, however, nothing else but the Pacific form of cerisyi, differing rcri/ slighth/ from 

 the eastern sjiecimens of this species, and having the thorn at the end of the fore- 

 tibia, just like eastern cerisyi. Sph. ocellata and cerisyi are closely related, and 

 can by no means be separated generically unless one proposes a genus for each 

 sjiecies. Grote holds now the same opinion.* Tutt, I.e., goes even farther than 

 did Grote : he considers the local forms of ccriayi to represent two genera I ! 



The thorn or claw at the end of the foretibia is here not a character of generic 

 value. This is best proved by ocellata and planus, which are very near each other 

 in every res])ect : the former, however, possessing the claw, the latter being without 

 it — a ditl'erence entirely overlooked by lepidoj)terists. 



The abdominal segments are said by Fernald, I.e., to be unarmed. 

 Smith have repeated this erroneous statement. 



Key to the species : 



n. Foretibia witli an apical thorn (claw) 

 Foretibia without an apical thorn (claw) . 



b. Hindwing with a large black anal patch 



which is round and includes a pale 

 blue ring or some pale blue sjiots 

 Hindwing before anal angle with two 

 resp. three black bars separated and 

 bordered by grey or buff bars 



c. The space encircled by the blue ring of the 



eye-patch more or less shaded with 

 bluish grey ..... 



The space black, the ring often incomplete, 

 sometimes represented by separate 

 spots ....... 



d. The blue ring of the eye-jiatcli comjilete, 



large, the space encircled by it more 

 or less shaded with pale blue 

 The blue ring incomplete or represented 

 by sejiarate spots .... 



e. Brown antemedian band of forewing 



strongly angulate in middle 

 Brown antemedian band of forewing 

 slightly curved ..... 

 The two American species and the Asiatic eaeeus have a high snbapical ridge 

 on the inner surface of the clasper, while the other three (Palaearctic) species have 

 the ridge merely indicated by a slight fold.
