FamiLty Il. FULGORIDEZA. 
Head of various forms, often with a cephalic prolongation and sometimes lumin- 
ous. The frons nearly always keeled. Ocelli 2, rarely 3 or wanting, placed beneath 
the eyes or sunken in the cheeks close to the eye, the third ocellus, when present, 
placed in the middle of the frons. Antennz always beneath the eye, usuaily large, 
distinct, the joints of which are frequently long and dilated, sometimes with an ap- 
pendage. Thorax weak, usually keeled ; scutellum small. Wings usually long and 
strongly veined, often short but rarely entirely wanting. Tegule most frequently 
present. Anterior coxe generally elongated ; posterior coxz transverse, contiguous, 
extending from the sides of the body. Tibize ichenie or foliaceous. Tarsi 3-jointed, 
generally spined. 
This is one of the most extensive of the homopterous families, well 
represented in North America, and comprises some of the most curious 
and interesting forms to be found among insects. 
The family may be divided into ten subfamilies, recognizable by the 
aid of the following table :
