FAUNA HAWAIIENSIS 



tropical countries, or at least neglected by the collector. Three of the species occur 

 in gardens in Honolulu and two of these are widely distributed outside, but they cannot 

 be looked on as forest insects. All three are found in the cane-fields. These are 

 Triphkps persequens, Pliysopleurella nmndula, and Biuhananiella sodalis. The first- 

 named will I think almost certainly prove to be foreign. It is partial to flowers, e.g. 

 those of Laiitana camara and preys on the Thysanoptera (introduced) that are found in 

 these. P. mundula and B. sodalis are sometimes found in company, the former being 

 especially common, sometimes occurring in countless numbers, as in the cane-fields at 

 Paauhau in 1903, hiding amongst the dead cane-leaves, where it preyed largely on 

 Psocidae and small leaf-hoppers. On the leaves of growing trees or shrubs, such as 

 crotons, oranges, mulberries, etc., the conspicuous red nymphs and mature bugs are 

 often found beneath the webs made by the Psocidae, which feed on the black 

 fungous growth, that springs up on the excretions of various scale insects infesting these 

 trees. One may find at such times a small flock of Psocids resting side by side with 

 their enemy, beneath the covering made by the former. Both P. mimdu/a and 

 B. sodalis may be found in decayed stems of plants, where, I believe, they feed on 

 Thysanoptera, which are found in this situation. Yet another small Anthocorid, at 

 present undetermined, has the same habits, and this also was present in the islands at 

 least thirty years ago. P. mundula exhibits considerable variability or I would rather 

 say that, until careful examination has been made, I do not feel sure that there is not 

 more than one species of its genus. 



Lasiochilus denigratus and its allies are true forest insects and live beneath bark or 

 in the cavities of dead twigs or stems, the nymphs being found in the same situations. 

 The specific characters appear to be feeble and uncertain. 



Lilia dilecta is also a forest insect and the genus is endemic. I have not met with 

 it, or at least neglected to collect it. I regret that I neglected to collect specimens of 

 one or more forest-dwelling Anthocorids, distinct from any of these. 



MiRiDAE. — The Miridae, better known to entomologists in general as Capsidae, 

 are represented by a greater variety of endemic forms than any other family of 

 Hawaiian Heteroptera. Eleven of the genera are endemic. Two recorded species 

 are certainly recent introductions, an undetermined species of Fitlvius (I believe the 

 same species as one I met with while inspecting introduced plants) and Halticus 

 chrysolepis, abundant in Honolulu gardens, where macropterous and brachypterous 

 forms occur together, the latter having mere rudiments of wings. Even so late as the 

 early part of 1909 single specimens representing two other genera of Capsidae, have 

 been found in Honolulu. These imported species are of very little interest, but their 

 occurrence renders it likely that one or two other Hawaiian species, not known from 

 elsewhere, may have been imported with plants at an earlier period. At the most 

 three, however, are open to suspicion. Oronomiris hawaiiensis, a very abundant species
