1913] Wing Venation of Fulgoridce. 347 



SUMMARY. 



Owing to the fact that the aduh wings of the Fulgoridas 

 vary so much it has seemed best to summarize the homologies 

 of adult wing veins by giving a discussion of the characters 

 of the adult wings of the various subfamilies. 



Sub-family Fulgorida. 

 Both the fore and hind wings of this sub-family are char- 

 acterized by a large amount of reticulation. Nearly all the 

 members of this sub-family are characterized by having a 

 large number of accessory veins. These accessory veins 

 may be added to radius, medius or cubitus, but in some cases, 

 as in Poiocera (Fig. 9) all three of these veins bear accessory 

 veins. In the hind wing radius and medius do not usually 

 bear many accessory veins, but cubitus usually has several 

 accessory veins. Another characteristic of the hind wings is 

 the fact that the cross veins are apt to be connected together 

 forming false veins between the principal veins. These false 

 veins usually lie along the folds of the wing. 



Sub-family Flatida. 

 The chief characteristics of this sub-family are: First, 

 that the costal vein is remote from the costal border of the 

 wing and connected with it by means of a number of cross 

 veins; second, that radius and medius are provided with a 

 large number of accessory veins; and third, that these accessory 

 veins are usually connected by a definite series of cross veins at 

 a uniform distance from the apical border of the wing. The 

 hind wing is chiefly characterized by the great development 

 of the anal area of the wing, and by a large number of accessory 

 veins attached to cubitus. 



Sub-family Acanaloniida. 



The fore wings of the members of this sub-family are 

 characterized by having a large number of cross veins between 

 the branches of the principal veins. They are also characterized 

 by having radius simple and unbranched, and the larger area 

 of the wing occupied by the branches of the medius. In some 

 cases, Amphiscepa (Fig. 15), medius is typically four branched 

 with the addition of accessory veins to some of the branches. 

 In other cases, Acanalonia (Fig. 17), medius is three branched,.
