xv, i Funkhouser: Philippine Membracidse YJ 



Pyrgonota 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. 



Pyrgonota 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. ■ StaPs 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. 



Pyrgonota 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 Mav 29, and one on June 30, 

 1918. 



The species has never been recognized since its original de- 

 scription ; * 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,
