PSEUDOPONTIA. 79 



Moth. Its short and non clavate antennae, pure white colour, 

 and greatly rounded wings, with very abnormal neuration will 

 prevent its being confounded with any other insect. It has 

 some external resemblance to the genus Leptosia (cf. our vol. 

 ii. p. 176), as well as to some of the rounder-winged genera of 

 Liparidcz among the Moths, such as Pantana, Walker. The 

 genus stands at present in the British Museum collection among 

 the Chalcosiid^ and although it differs from them greatly in 

 the structure of its antennae, the curiously irregular neuration 

 of the insect may show some affinity to that Family, though we 

 prefer to separate it as quite distinct from any other. 



The two Felders were the first authors to notice this insect, 

 which they received from Calabar, and pointed out its re- 

 semblance to a Cicada (or rather a Flata). "The wings 

 are wholly without markings, short, shining, and much 

 rounded ; the antennae nearly filiform, and very distinctly 

 jointed ; the eyes are large and round, but not prominent, 

 and this gives the head a completely rounded appearance; 

 the cell of the fore-wings is very narrow, and the first sub- 

 costal nervure is much curved. We believe it to be allied to 

 Pontia? Some correspondence on the subject ensued in the 

 "Petites Nouvelles," where this preliminary notice first ap- 

 peared ; and Hewitson expressed his opinion that the insect 

 was a Moth (in which he was afterwards followed by Butler), 

 and also pointed out that Plotz' figure, published in the interim, 

 represented the antennae as clavate, thus giving the insect more 

 of the appearance of a Butterfly than it actually possesses. 

 Rudolf Felder then published a figure in the " Petites Nou- 

 velles," remarking : "It evidently belongs to the great division 

 of Rhopalocera, according to the character indicated by Herrich- 

 Schaffer (Schmett. Eur. i. pp. 13, 15); the joints of the 

 antennae being longer than broad. It has also all the appear- 

 ance of one, though it has some resemblance to certain
