in others the vertex is longer and produced snout-like be- 

 fore the eyes. 



The frons in nearly all cases is more or less definitely 

 carinated and in certain genera one finds numerous coarse 

 or fine pustules on the sides. Below the frons is found the 

 :lypeus which is usually separated by a more or less definite 

 suture but in rare cases these two parts are fused. The 

 clypeus is composed of three segments and is generally 

 triangular, with or without a median keel. The genae or 

 cheeks are the lateral parts of the head. In the Fulgorids 

 they are actually placed laterally and are hollowed. 



The usual number of ocelli is two but in some (in most 

 Cixiinae) there are three, two in the usual Fulgorid posi- 

 tion placed close to the antennae at the more or less flat 

 sides of the head, and one at the anterior margin of the 

 frons, adjoining the clypeus. The function of the ocelli is 

 little understood but if used for vision, their usefulness 

 must be greatly limited in this family by the surrounding 

 elevated keels or carinae. 



The antennae are of varied shapes and sizes, the first 

 segment usually cylindrical, more or less elongate or notice- 

 ably lengthened, but often very short, the second enlarged
