weak, bluntly rounded. ^Edoeagus short, blunt, truncate 

 (rose thorn) spine before orifice. Cornuti short, stout, in 

 patch about sixteen. Cristse set with six spines. Saccus 

 short, rounded. 



Ostium produced. Signum discoid stellate. 



Sylvata, Scop. 224 



Valvula short, dentate, deeply emarginate at anal angle, 

 the point scobinate; costa separate, long curved arm with 

 single spine at apex. Uncus weak, except tip, which is 

 stronger and rounded; behind the uncus at the end of the 

 ninth tergite is a hairy papilla which varies considerably 

 in size. JKdceagus cylindrical, with strong, short, truncate 

 rose thorn at orifice. Cristae a rounded patch of spines. 

 Saccus bluntly pointed. 



Ostium with operculum. Ductus bursae thickened. 

 Signum discoid stellate. 



Pantaria, L. 61 



This species has, as far as we are aware, never been taken 

 in England, although it has often been recorded. We have 

 examined a number of so-called pantaria, but in each case 

 they have been proved to be sylvata. 

 f The genitalia are very distinct and we have added a 

 figure, so that any doubtful specimens may be examined 

 and proved whether they are this species or not. 



The main point of difference lies in the deep emargma- 

 tion of the valva before the large emargination. In 

 pantaria it is deep and forms two long claws, which are not 

 specially noticeable in sylvata. We have also examined a 

 number of other specimens from various parts of the 

 world, all very similar in wing markings to sylvata and 

 find the genitalia show a number of distinct species. 



Valvula short, dentate, anal angle emarginate, point 

 not scobinate; costa separate, long curved arm with single 

 spine at apex. Uncus weak, except at tip, which is 

 stronger and rounded. No hairy papilla on ninth tergite.
