Gexus XXIX.— PHRYGANEA Auctorum. 



AntcniiuE setaceous, approximating, longer than the body, but shorter than the 

 wings, slightly pubescent beneath : palpi rather pulsescent ; maxillary of 

 the male 4-jointed, of the female 5-jointed, the terminal joint elliptic-ovoid : 

 labial 3-articulate in both sexes, the apical joint of the male robust, some- 

 what ovate, of the female more slender and somewhat elliptic : head ovate : 

 eyes globose, prominent : thorax ovate : wings slightly deflexed during 

 repose; anterior elongate, lanceolate, with a waved line of transverse 

 nervures, placed rather beyond the middle, at the origin of the bifurcation 

 of the longitudinal ones ; posterior more ample, ovate-triangular : abdomen 

 of the males compressed, and furnished at the apex with two long, incurved 

 horny appendages, two shorter ones below them, and a bilobed one between ; 

 of the females robust, and obtuse at the apex : legs rather stout ; tibioe with 

 numerous short spines, and two spurs at the apex, the two hinder pair with 

 a second pair of spurs below the middle; the hinder tibiae long and curved. 

 Larva with the head and following segment scaly, the 5th segment much 

 dilated on the sides, the respiratory organs prominent, and placed obliquely, 

 the apex of the abdomen with two hooks ; case formed of pieces of aquatic 

 plants. 



This genus contains the largest species of the order, and, exclu- 

 sively of their great bulk, they may be known by having the terminal 

 joint of the palpi rather short and ovate ; the palpi themselves are 

 dissimilar in the sexes, those of the males being 4-jointed, and of the 

 females 5-jointed : the wings are in general ornamented with rather 

 conspicuous colours, the anterior being somewhat lanceolate, and 

 rounded at the apex, and the posterior being very simple, and of 

 plain colours.
