H E M I P T E R A— H ETEROPTERA 



By W. E. China, B.A. Cantab. 



(With 28 Text-figures.) 



The present fascicle deals with the whole of the Heteroptera with the exception 

 of the Miridae, which are being worked out by Dr. H. H. Knight, and the aquatic 

 families, which have already been dealt with by Prof. Teiso Esaki in Fascicle 2. 



Previous to Esaki's paper only five species of Heteroptera had been 

 recorded from the Samoan Islands. The first of these was the Coreid Mictis 

 crux described by Dallas {List Hemipt. Het. Brit. Mus., II, p. 405) in 1852, when 

 the group was known as the Navigators Islands. The second was Noliphus 

 discopterus, a new Coreid species described by Stal in the third volume (p. 87) 

 of his splendid Enumeratio Hemipterorum, in 1873. In the fourth volume of 

 the same work (p. 146, 1874), Stal described still another Samoan species, the 

 Lygaeid Bedunia insularis. Thirty years later Schouteden (Wytsm. Gen. Ins., 

 xxiv, p. 31, 1904) recorded, without remark, the fourth species Calliphara 

 bifasciata A. White, which was already known to occur in the " South Sea 

 Islands." In the same work Schouteden also recorded Coleotichus excellens 

 Walk, as occurring in Samoa, but it is most probable that this record actually 

 referred to the fifth species, which Schouteden (Notes Leyden Mus., xxix, 

 p. 207, 1908) later described from Samoan material under the name Coleotichus 

 buloivi. 



The present contribution deals with sixty species representing forty-six 

 genera and one subgenus, so that, including the ten aquatic species recorded by 

 Esaki, the known Samoan Heteropterous fauna (apart from Miridae), amounts 

 to seventy species belonging to fifty-one genera. As shown in the following 

 table, these figures are not unlike those of the Imown Heteropterous fauna of
