carinate above, impinging on inner margin of tegmina for entire 

 length below, reaching barely to internal angle of tegmina. Teg- 

 mina fuscous hyaline, slightly wrinkled, base dark brown and 

 punctate, veins distinct and brown, narrow brown fascia at 

 extreme exterior tip. Sides of meso- and metathorax directly 

 behind eyes covered with snowy white tomentosc patch. Under- 

 surface of body black, slightly pubescent. Femora very dark 

 brown, except extremities which are ferruginous; internal 

 margin of hind trochanters strongly armed with teeth, tibiae 

 simple and ferruginous; tarsi and claws yellow-ferruginous. 

 Type, male. 



Length, 4.5 mm. ; width between extremities of horns, 1.9 mm.

Genus CENTROTUS Fabricius 



The advisability of giving the genus Centrotus a place in this 

 study is extremely doubtful. It is included entirely on the 

 strength of the descriptions of three species from the Philippines 

 which have been assigned to this genus but which have never 

 been recognized since their original publication. 



The genus is one of the oldest and best known of the genera 

 of the Membracidse, being established by Fabricius in his 

 Systema Rhyngotorum in 1803, and has contained at various 

 times a large number of species now removed to other genera. 

 It appears probable that the species here given will be likewise 

 removed if they are discovered, since the characters of Centrotus 

 are much less inclusive than formerly. 



The genus as now limited may be recognized by the shape of 

 the posterior process which is distinctly separate and somewhat 

 remote from the scutellum, somewhat extended and widened 

 beneath, then rather abruptly becoming slender, the tip often 

 touching the tegmina. No spines are present on the hind tro- 

 chanters; the hind wings have three apical areas; the supra- 

 humeral horns are always well developed. 



The following must be considered as lost species until exam- 

 ination of type material or careful study of long series of 

 specimens makes their recognition possible.
