ing the tip of the wing pad. In Myndus (Fig. 47), medius is 

 typically four branched with an accessory branch between 

 medius one and medius two. 



The Cubitus and the First Anal of the Fore Wing. 

 As in the Jassidce the cubital-first anal group forms the 

 most characteristic land-mark in the tracheation of the Ful- 

 goridas. These two trachea are united for a short distance 

 from the body trachea and cubitus is usually two branched. 

 In Thionia (Fig. 27), Dictyophara (Fig. 25) and Acanalonia 

 (Fig. 1), cubitus is unbranched, while in Phylloscelis (Fig. 7), 

 cubitus is two branched and in Stobcera (Fig. 45), there is an 

 accessory branch between cubitus one and cubitus two. 



The Second and Third Anal of the Fore Wing. 

 The second anal trachea is a simple unbranched trachea 

 and usually lies parallel with the first anal trachea. The third 

 anal trachea is nearly always present in Fulgoridee and is usually 

 two branched. The second branch when present usually 

 forms the anal border of the fore wing. 



THE HIND WING. 



The hind wing of the Fulgoridas is almost as variable as 

 the fore wing, very little similarity being observed in the 

 different genera of some of the sub-families. Quite a little 

 variation is frequently observed in different individuals of the 

 same species. 



The Costa of the Hind Wing. 

 The costal trachea is present in the following widely sepa- 

 rated genera: Myndus (Fig. 48), Scolops (Fig. 24), Dictyophara 

 (Fig. 26), Thionia (Fig. 28), Acanalonia (Fig. 2), and Phyllos- 

 celis (Fig. 8). In Thionia, -Phylloscelis and Myndus it is united 

 with subcosta for some distance from the body trachea. In 

 Scolops it is present only as a weak trachea at the base of 

 the wing. 



The Subcosta of the Hind Wing. 



The subcostal trachea was found in all the wing pads 



studied. In most of the genera it runs parallel with radius 



for almost its entire length and diverges at the tip. The 



radial and subcostal trachea are included in a common vein
