VYRALlD.t: I'AUAPOYKX. 41 



Genus CCLXVI. — Parapoynx, Hiihner, 



Palpi four, maxillary distinct, acute, remote ; labial approximating, ascending, 

 rather densely clothed with short scales, triarticulate, the terminal joint 

 nearly vertical, ovate-acute when denuded : maxilla: very short. Antennas 

 short, curved at the apex, somewhat denticulated in the males, simple in the 

 females : head small, smooth between the antennse : thorax rather stout : 

 wings placed in a triangle during repose, anterior elongate, somewhat 

 rounded on the hinder margin, the disc with transverse waved streaks, and 

 a subocellated spot ; posterior ovate-triangular, entire : abdomen moderate, 

 slender, with a small tuft at the apex in the males ; stouter and rather acute 

 in the females: legs moderately long and slender; posterior tibia with two 

 pair of spurs. Larva slender, with sixteen legs : found on aquatic plants. 



From the three foregoing aquatic genera the present genus differs 

 so considerably in habit as at cnce to suggest the propriety of its 

 separation : without attending to the trifling variations of the trophi, 

 the form and markings of its wings will enable the reader to discrimi- 

 nate it, the hinder margin of the anterior being somewhat rounded, 

 and the disc transversely streaked with flexuous lines, and having in 

 the middle a blind ocellus. 



Sp. 1. Stratiotata. Alis anticis albis (^faeminw rufo-fuscescentibus) atomis fas- 

 ciisquefuscis, macula nived nigro-cinctd, posticis niveis fasciSi interrupta fused.

 No. 6802. 



Wings of the male white; anterior with brown atoms, an indistinct oblique 

 abbreviated darker streak on the inner margin, towards the base, and a 

 second more distinct repanded one behind the middle, between which is 

 placed a snow-white spot, edged with black : on the hinder margin is a 

 faint double fuscous line : posterior wings brighter, with a strong waved 

 interr\ipted dusky line behind the middle. Female with the anterior wings 

 narrower and more acute at the apex, and almost entirely of a pale reddish- 

 brown, without streaks, and the central white spot very small and indis- 

 tinct; posterior wings as in the male, but of a reddish-brown hue. 



Also variable in the colour and intensity of the markings. 



The caterpillar feeds chiefly on the Stratiotes, but it also attacks other 

 aquatic plants ; it is green, with a broad paler dorsal line, and varied with 

 whitish and yellow: the imago appears towards the end of June or 

 beginning of July. 



Not unfrcqucnt in marshy places within the metropolitan district ;
