CaliiSj/mbolKS was originally projxised for asfj/lus, but later on employed 1\v 

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



(Jrote's subgenus Copismerinthua has no justification whatever. When the 

 author learned from Fernald's Sphingidae of Neio England that cerisyi had the 

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

 (piite ciiaracteristic, not being aware that the European ocellntd, which he considered 

 tiie type of Smerinthus, possessed tiie same armature. In the same paper Grote 

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

 America, tlie only representative of tlie tyjiical genus Smerinthus. Tliis ophthalmicus 

 is, however, nothing else but tlie Pacific form of cerisfji, differiug rrr)j slighthj from 

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

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

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

 s])ecies. Grote holds now the same opinion.* Tutt, I.e., goes even fartlier than 

 tlid (irote : he considers the local forms of cerisyi to represent two genera ! ! 



The thorn or claw at tlie 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 diiference entirely overlooked by lepidojiterists. 



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

 Smith have repeated this erroneous statement. 



Key to the species : 



a. Foretibia with an apical thorn (claw) . . . h. 

 Foretibia without an apical thorn (claw) . . . d. 



b. Hindwing with a large black anal patch 



which is round and includes a pale 

 blue ring or some pale blue spots . . . c. 

 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 ....... 



(/. Tlie blue ring of the eye-]iatcli comjilete, 



large, the space encircled by it more 



or less shaded with pale blue 



The blue ring incomplete or represented 



by separate 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 caecus have a high subapical ridge 

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

 the ridge merely indicated by a slight fold.
