PSEUDOPONTIA. 79 



NIoth. Its short ami non clavatc antcniicT, pure white colour, 

 and greatly rounded wings, with very abnormal ncuration 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 

 Liparidcc among the Moths, such as Pantami, ^Valker. The 

 genus stands at present in the British Museum collection among 

 the Chalcosiidcv, 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 Flaia). "The wings 

 are wholly without markings, short, shining, and much 

 rounded ; the antennce 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 

 Pontiay Some cories[)ondence 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 P16tz' figure, published in the interim, 

 represented the antennx as clavate, thus giving the insect more 

 of the appearance of a I3utterfly than it actually possesses. 

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

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

 (i{ Rhopaloccra, according to the character indicated by Ilerrich- 

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

 antenncB being longer than broad. It has also all the ai)i)ear- 

 ance of one, though it has some resemblance to certain
