most difficult to deal with, and unless they be specially collected 

 and carefully mounted, while fresh, are of little practical use. 

 The spread of many imported species amongst the native ones, 

 both belonging to the same genera, has rendered the study of 

 the endemic fauna still more unsatisfactory. 



RHYNCHOTA. 



At a recent meeting of this Society I exhibited a collection of 

 over fifty species of Rhynchota that I had recently taken in ten 

 days of general collecting in the immediate neighborhood of the 

 Hotel. These included Capsidae (10 species), Reduviolus (7), 

 Nysius (5), Sephora (1), Orthoea (1), Ithamar (1), Acanthia (2), 

 Oechalia (1), Coleotichus (1), Oliarus (4), Jassidae (7), Delphaci- 

 dae (10), Psyllidae (several). By extending one's collecting 

 ground to Olaa and adjoining districts this list could be much in- 

 creased, or even by special research at Kilauea itself, since the 

 list includes no species of Emesidae, Anthocoridae, etc. Some 

 of these I have on other occasions found very numerously there. 

 The species of Acanthia were found running on tree trunks, high 

 up above the ground, in the damp fern forest. I do not remem- 

 ber to have noticed them in this situation before. Of the other 

 bugs the species of Redtiviolus axe the most interesting,, each 

 having its own special habits or habitat, but on the whole the 

 bugs are much less interesting than the Neuroptera of Kilauea. 



THYSANOPTERA. 



• As everywhere in the islands, Thysanoptera are very abun- 

 dant and the species are probably numerous. They require 

 special collecting and mounting, and as they probably present 

 long series of very closely allied species like the genera of Ha- 

 waiian insects, the discrimination of the species is likely to be one 

 of great difficulty. The wingless forms are much more bulky 

 than the winged, as is so often the case in many apterous or 

 subapterous Rhynchota. 



COLEOPTERA. 



It is not possible at present to compile a complete list of the 

 Kilauea Coleoptera, partly because many species are not as yet 

 described, and partly because some, collected abundantly in 

 other localities, have not specially been registered from this one 

 This latter remark applies still more strongly to the Lepidoptera
