348 NOTES ON THE HEMIPTERA OF THE HAWAIIAN ISLANDS, 



of the antennfe entirely of a more or less dark fuscous colour, and 

 the penultimate segment of the hind body is much less emarginate 

 behind in the female. 



A few specimens occurred among vegetable refuse on Mauna 

 Loa, Hawaii, at an elevation of about 4000 feet above the sea. 



N.B. — I possess a single specimen of Metrarga from Kauai 

 Avliich appears to me to be so close to M. mida, White, that I 

 hesitate to treat it as distinct. At the same time I feel little 

 doubt (on the sexual characters alone) that it is distinct, for my 

 specimen (which is a 5) has the penultimate ventral segment 

 scarcely emarginate. 



CAPSINA. 



The Capsina are, comparatively speaking, rather plentiful in 

 the Hawaiian Islands. I posse.ss upwards of forty species, of 

 which I have not been able to send much more thaa a dozen to 

 Dr. White. Unfortunately these are among the frailest of 

 insects, and a great many of my species are represented by single 

 types, some of them in inferior condition. From collecting 

 expeditions 1 was usually obliged to bring home most of my 

 captures unmounted, in sawdust, and the Capsina often suffered. 

 The obscurity and difficulty of this group are so great that I 

 think an entomologist who has not made them a special object of 

 study would be more likely to hinder than assist future workers 

 if he attempted to deal with them in print, and I act on this 

 opinion by passing on without further remark to the 



ANTHOCOPtlNA. 



This group is not richly rei)resented, as far as T have observed^ 

 in the Hawaiian Archipelago. Acanthia lectularia, Linn., is dis- 

 tressingly abundant, and the species of Cardiastethis are not 

 uncommon. (I have a single specimen of an insect allied to 

 C. sodalis, White, which is probably new, but I shall not venture 

 to descriVje it). The single species of Lilia and the two of DHasia 

 are not infrequently met with in beating branches of trees on the
