specimen of Conocephaloides was taken on a Pipturus tree. 

 Around the volcano the little Gryllids Paratrigonidium varians, 

 grande and pacificum are found, while lower down, towards Olaa, 

 is a rich locality for these, P. viridescens, filicum and freycinetiae, 

 being found in addition to these above named. I have spoken 

 of the distinct habits of these difficult species in the Fauna Ha- 

 waiiensis. Leptogryllus elongatus is found in the fern forest in 

 some numbers, but L. similis is much rarer. 



NEUROPTERA. 



Of the Hemerobiidae our single species of Megalomus is com- 

 mon; Nesomicromus is very well represented by vagus, paradoxus, 

 longispinosus, brunnescens, rubrinervis, subochraceus and mini- 

 mus. The second and third of these are the most interesting and 

 the rarest. Lacewing flies are very common; Anomalochrysa 

 peles, montana, rufescens, f rater, longipennis, deceptor, raphi- 

 dioides, proteus and rhododora are all found, though rufescens and 

 raphidioides prefer a lower elevation on the Kau side; pauros- 

 ticta, princeps, and probably others, are found in the densest 

 forests in Olaa in the' winter months. A. peles, rhododora and 

 its remarkable var. xerophylla and longipennis are the most 

 desirable of the volcano species. A. montana is peculiar in fre- 

 quenting the low-growing shrubs of the open country {i. e., the 

 first region described by me) where one disturbs it in numbers 

 as one walks along in the daytime, at certain seasons. Formi- 

 caleo wilsoni is found in the same open country about two miles 

 from the Volcano House on the Kau side. 



Of the dragon flies, Anax strenuus and Nesogonia blackburni 

 may be observed anywhere, owing to their powers of flight. 

 Specimens of Agrion are numerous around the hotel vegetable 

 garden in the fern forest, as well as on the path near Kilauea-iki, 

 and generally on the Hilo side of the crater. They are also 

 abundant in Olaa and about Hilo. Agrion nigro-hamatum, 

 asteliae, amaurodytiim, race peles and var. fallax, calliphya race 

 microdemas, nesiotes and deceptor are found close to Kilauea, 

 to which at low elevations may be added A. xanthomelas , paci- 

 ficum and blackburni. A. nesiotes is by far the most peculiar 

 and interesting of these species and it is not rare. 



Psocidae are very numerous in individuals, but the species 

 being very unstable in specific and even in generic characters are
