The genus Celerio was described ( Lehrb. Zool., i., p. 761) in 18 15, 

 by Oken, as follows : 



Halbbandierte, halbringleibige Schwarmer ; Fleckenraupen. Larva with 

 small, globular, not retractile head, body smooth, a caudal horn, coloured lateral 

 spots. Pupa on the earth among leaves. Imago with interrupted rings on the sides 

 of the abdomen ; tongue longer ; forewings elongate, smooth-margined, inner 

 margin hollowed ; antennae of almost uniform thickness, scaled beneath, apex thread- 

 like — Celerio gallii, euphorbiae. 



The genus is, according to the showing of Weismann (larvae) 

 and Kaye (imagines), heterotypical, and we fixed the type of the 

 genus (anted, vol. iii., p. 355) as gallii. Kaye makes (in litt.) gallii 

 the centre of a small group of Phryxids, which he defines as 

 follows : 



Head not prominent, nor markedly projecting ; forewings not so long as 

 in Phryxus, and less pointed ; with oblique band from apex to near base 

 giving off two or more short teeth or branches ; spines on front tibia nearly all 

 of uniform size — Celerio gallii, eaphorbiarum, zygop/iylli, ? opheltes. 



This he has now supplemented (in litt.) by a more detailed 

 diagnosis, which reads : 



Head not large, nor markedly prominent, but fairly pointed. Palpi bluntly 

 pointed. Thorax broadest at costal base of forewing. Abdomen not long, tapering 

 rapidly from the 4th segment to tip. Forewing of medium length, the co.^ta 

 straight to beyond the origin of 7, then very slightly curved, and finally sharply 

 curved to apex. Outer margin slightly curved from apex to nervure 5, then 

 straight to termen. In the ? the margin is straighter. Inner margin curved 

 very slightly inwards soon after leaving termen. Nervures 7, 8 stalked, 9 from 

 two-thirds length of cell. Cross-nervufe of cell evenly curved inwards. Nervure 2 

 from well before half length of cell. An oblique band from apex to near base 

 giving off two or more short tooth-like marks, llindwing with costa evenly arched, 

 apex very blunt; outer margin evenly curved to nervure 3, thence to nervure \b 

 considerably curved inward, forming a fairly sharp point at the extremity of nervure ;
