1913] Wing Venation of FulgoridcB. 349 



the tip. In Thionia (Fig. 36), the anal area of the hind wing 

 is larger than the preanal area, and third anal is characterized 

 by the addition of a large number of acce'ssory veins. In 

 Bruchomorpha (Fig. 34), the hind wing is greatly reduced in 

 area, and the principal veins only are represented by simple 

 unbranched veins. 



Sub-family Derbida. 

 In this sub-family, also, subcosta and radius are coalesced 

 for a considerable distance from the base, and both are typically 

 two branched; although in some cases, Otiocerus (Fig. 39), there 

 are a number of cross veins between subcosta and the costal 

 border. Medius is typically four branched with a number of 

 accessory veins added to medius one. In Anotia (Fig. 37), 

 and Otiocerus (Fig. 39), there is an accessory vein between 

 medius three and four. In Lamenia (Fig. 41), there are no 

 accessory veins between medius three and medius four, and 

 only a single accessory vein between medius one and medius 

 two. Cubitus is typically two branched, but in Otiocerus 

 and Anotia these branches do not extend to the anal border 

 of the wing, but unite with the coalesced anals at some little 

 distance from the border of the wing. In the hind wings, 

 subcosta and radius are coalesced, and medius is two branched 

 in Anotia (Fig. 38) and Otiocerus (Fig. 40), but unbranched 

 in Lamenia (Fig. 42) . Cubitus of the hind wing is two branched 

 in all of the members of this sub-family which I have examined. 



Sub-family Cixiida. 



This sub-family also is characterized by the fact that 

 subcosta and radius are coalesced for some distance from the 

 base. Subcosta is typically two branched, although in Both- 

 riocera (Fig. 60), Oliarus (Fig. 58) and CEcleus (Fig. 62) super- 

 numerary veins are added between subcosta one and subcosta 

 two. Radius is typically three branched, although these 

 branches are somewhat variable in their relationships. Medius 

 is typically four branched with an accessory vein between 

 medius one and medius two, although in Oliarus (Fig. 58), 

 both medius one and medius two bear accessory veins. Cubitus 

 of the fore wing is typically two branched, and second and third 

 anals are coalesced at the tip. In the hind wing subcosta and 

 radius are coalesced for a considerable distance from the base,
