apex, gradually becoming slender; anterior and posterior uni- 

 carinate, the sides with two or three carinas; apex somewhat 

 thick, truncate, and compressed anterior-posteriorly ; carinate, 

 the posterior carina minutely denticulate and extending upon the 

 posterior process. Posterior process acutely tectiform, subcom- 

 pressed. Tegmina with pale spot before apex of clavus. Hind- 

 wings vitreous. Feet flavous-pitchy. 



Length, 8 mm. ; width, 2.2 mm. 



Described by Stal from the female only. 



Philippine Islands (Stal). 



I am inclined to think that this is the female of P. tumida, but 

 am recognizing it tentatively, pending an opportunity to examine 

 more specimens. 



Pyrgonota bifurca Stal. 



Pyrgonota bifurca Stal, Hem. Phil. (1870), 731. 



Piceous; head slightly punctate, thorax strongly punctate. 

 Dorsal process varying in length, gradually becoming slender 

 and leaning somewhat forward; anterior and posterior margins 

 unicarinate, sides with two carinse; apex with two slender 

 triquerate processes, strongly diverging and slightly curving, 

 compressed-ampliate in the middle. Posterior carinse spiny, 

 continuing on the posterior process. Posterior process acutely 

 tectiform, narrow as seen from the side. Feet concolorous. 



Length, 7.5 mm. ; width, 2 mm. 



Philippine Islands (Stal). 



Pyrgonota semperi Stal. 



Pyrgonota semperi Stal, Hem. Phil. (1870), 731. 



The species noted by Stal as "C. Semperi" in his work on 

 the Philippine Hemiptera has never been recognized and is 

 known only through his short description, which follows that 

 of P. bifurca and is as follows : 



Praecedenti maxime affinis, differt processu postico thoracis ante medium 

 macula pallescente notato, pone medium quam anterius altiore, tegmini- 

 busque totis piceis. ? Long. 7, lat. 2 mill. 



I have included this species in the preceding key, with the 

 specific distinctions as indicated, in the hope that future collect- 

 ing may lead to its identification. 



Pyrgonota pinguiturris sp. nov. Plate I, fig. 3. 



Pyrgonota pinguiturris is apparently near P. tumida Stal, but 

 differs in being without carinse on its pronotum and lacking the 

 spot on the tegmina.
