3rd divides in the middle of its length, the interspace being short tri- 

 angular. 5th subcostal is slightly removed at its origin towards the 

 middle of the discal space. 2nd and 3rd median nervules are very 

 short, dividing on the first third of the distance from the discal ner- 

 vules. 4th 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 9 . The two subcostal nervules are thrown 

 off very near the apex. In both wings the two discal nervules are con- 

 tinuous and very oblique. The 2nd and 3rd median are very short, 

 arising very near the outer margin of the wing. 



Legs long and slender, closely and finely scaled ; hind tibia? 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. 



This genus is not only much larger than Heterogijnis but differs from 

 it in many respects. On comparing our species mentioned below with 

 H. penella from Southern France, received from Prof Zeller of Mese- 

 ritz, I find the antennae of Phryganidia are shorter in proportion, and 

 more broadly pectinated. The costa of the fore-wings is straight, and 

 the apex rectangular, instead of being rounded as in the European 

 genus, and the whole wing is broadly triangular, as are the hind wings, 

 which only reach to the tip of the abdomen, while in Hi^ferogijnis they 

 reach beyond. The neuration of the two genera is very dissimilar. In 

 our genus the median nervules are longer, and arise much nearer the 

 middle of the wing, especially the 4th median. The 2nd and ord me- 

 dian nervules in both wings are in Heterog/jnis remote at their origin, 

 while in Phryganidia they arise from a common branch which is thrown 

 off from the main nervure. This is very abnormal in the moths, and 

 in this present example is evidently the result of the wonderful analo- 

 gies of this group to the Phryganidae, and the Neuroptera generally, 

 where these irregularities in the arrangement of the nervures and their 

 branches, becomes almost a law.

Sable brown, partially transparent. Antennae and nervules darker.
