ZYGiENIDiE. 

 ZYGiENIN^. 

 Genus PHRYGANIDIA. Packard. 



Front broad, narrowing towards the mouth, sides parallel. In the $ 

 the clypeua is shorter than in the $ . Maxillae as long as the thorax. 

 Palpi ascending, curved, very narrow and slender, tips just passing 

 beyond the front; third joint continuous with the second. Antennae 

 long and broadly pectinated, in the ? subsimple; pectinations being 

 nearly obsolete. 



Thorax moderately stout, the patagia are more hairy than the rest of 

 the thorax. Wings long and broad. Primaries : length to breadth as 

 7.5 to 3.6. Costa slightly convex, straight in the middle. Apex sub- 

 rectangular, obtusely rounded. Outer margin moder- 

 ately oblique. First subcostal straight, arising just be- 

 fore the origin of the third subcostal; second arises more 

 than half way between the origin of the third and fifth; 

 third divides in the middle of its length, the interspace 

 being short triangular ; fifth subcostal is slightly removed at its origin 

 towards the middle of the discal space. Second and third median nerv- 

 ules are very short, dividing on the first third of the distance from the 

 discal nervules. Fourth median very short. 



Internal angle of the secondaries much rounded, hardly reaching to 

 the tip of the abdomen. Costa straight, a little full near the base, while 

 the wing is much produced towards the much rounded obtuse apex, 

 being still more rounded in the ? . The two subcostal nervules are 

 thrown off very near the apex. In both wings the two discal nervules 

 are continuous and very oblique. The second and third median are 

 very short, arising very near the outer margin of.the wing. 



Legs long and slender, closely and finely scaled; hind tibiae long, 

 provided with four moderate equal spurs; tarsi nearly as long as tibia. 

 Abdomen cylindrical, long, rather slender, tip obtuse. In the ? it is 

 shorter and obtuse. 



The genus is not only much larger than Heferogvnis, but differs from 

 it in many respects. * * * "Wx^ neuration of the two
