xv, i Funkhouser: Philippine Membracidx 17 
Pyrg'onota bifoliata Westw, 
Add: Habitat. — Panay, Antique Province, Culasi {McGregor) . 
Eighteen specimens collected at Culasi by Mr. McGregor in 
1918. Two specimens were taken in the forest at an altitude 
of about 700 meters on May 18, one on May 24, three on May 
29, one on May 30, ten on June 15, and one on June 20. 
This species has often been figured to represent the grotesque 
and unusual development of the pronotum in the Membracidse 
and usually stands as a “show species” in museums. It is un- 
usual to find so large a series as the present material offers. 
Pyrgonofa bifurca Stal. 
Add: Habitat. — Luzon, Baguio, Benguet Subprovince {Baker). 
This is the first record of this species since its original de- 
scription by Stal in 1870. 3 Stabs description is very detailed 
and closely fits the single specimen from Baguio. The lateral 
carina on the posterior process of the pronotum is not as dis- 
tinct as might be expected from the original description but is 
rather irregular throughout and obsolete at the extremity. In 
all other respects, however, the characters seem identical. The 
specimen before me bears Professor Baker’s duplicate No. 7657. 
Pyrgonofa semperi Stal. Plate I, figs. 2 and 3. 
Add: Habitat. — Panay, Antique Province, Culasi {McGregor) . 
Host. — Acalypha stipulacea Klotz. 
It has been a great pleasure to be able at last to recognize 
this species from three specimens collected by Mr. McGregor 
at Culasi — one on May 28, one on May 29, and one on June 30, 
1918. 
The species has never been recognized since* its original de- 
scription ; 4 this description is very meager, being merely four 
lines of Latin comparing the type with P. bifurca. However, 
I feel confident that the Culasi material represents the insect 
which Stal described. It has the pale marking on the posterior 
process which is the chief distinctive character according to 
Stal, and the measurements exactly agree with those of the 
type. On account of the fact that the original description is 
so brief and the fact that the species has never been figured, 
I am including a more complete list of its characters as follows : 
Very dark brown, almost black, coarsely and evenly punctate, 
sparingly pubescent with grayish hairs; pronotal horn long,
