STUDIES IN PHILIPPINE HETEROPTERA, I 



By E. Bergroth 

 (Jdmsd, Finland) 



Since 1870, when Stal published his important paper Hemip- 

 tera Insularum Philippinarum, which includes three hundred 

 twenty-one species of Heteroptera, only a small number of 

 species belonging to this suborder has been added to the Philip- 

 pine fauna in scattered papers by Lethierry, Reuter, Montandon, 

 C. S. Banks, Distant, Breddin, Kirkaldy, Horvath, Martin, and 

 myself. It is a great drawback that the Hemiptera collected 

 by Prof. Carl Semper, on which Stal's work was based, bear 

 no exact locality labels, not even the islands where they were 

 found being indicated ; we only know that most of his collections 

 were made in Luzon, and that a smaller part of them is from 

 Cebu and Mindanao. 



During the last four years Prof. C. F. Baker has endeavored 

 to bring together specimens of Philippine insects, and his efforts 

 have proved a great success, of which the contents of this and 

 many foreign journals give evidence. Professor Baker has 

 kindly submitted to me for study his Philippine Heteroptera, 

 excluding the Miridse, Anthocoridse, Nabididse, and a few other 

 smaller groups, which were entrusted to Doctor Poppius, who 

 thus far has described many of the new Miridse in the Annales 

 Historico-Naturales Musei Nationalis Hungarici, the Wiener 

 Entomologische Zeitung, and This Journal. A few of the new 

 Pentatomidae from Professor Baker's collection have been de- 

 scribed by me in the Annales de la Societe Entomologique de 

 Belgique and the Annals and Magazine of Natural History. In 

 the present paper, to be followed by others as soon as may be, 

 I am giving descriptions principally of new Myodochidse and
