viously from their movements also when pairing, though I failed to 

 hear the sound under these circumstances. 



Of other groups, Aculeate Hymenoptera were unusually scarce, a 

 few species of Odynerus and Crahro, two or three of .Prosopis and 

 Mhnesa nntennata were taken, besides which there were a few rather 

 nice IchneumonidcB and minute Chalcids. 



Of Heteroptera the best were two species of Emesiidce, one an 

 apparently apterous form. These excessively delicate gnat-like crea- 

 tures with raptorial front legs were preying on the young of various 

 species of Fsocus. 



Neuroptera. — Two bright red and black Agrions abounded through- 

 out the forest, and two or three other species were in lesser numbers. 

 The nymphs go through their last changes with surprising quickness. 

 On one occasion 1 collected about a dozen of them in a cooking tin 

 in the morning, when they were swimming around in a small pool ; on 

 my return towards evening several perfect dragon-flies were already 

 hatched out. 



Besides these, a few really beautiful species of Chrysopa and 

 Hemerohius occurred, and several species of Fsocus were very abundant. 



Orthoptera were represented by a species each of the apterous 

 Prognathoqryllus and gi'een Brachymetopa, the latter identical with 

 the species in the West Maui Mountains, but very distinct from the 

 Oahuan form. 



Above the forest the country is very different, and has a number 

 of peculiar species. I visited the summit on one occasion, 10,000 feet 

 above sea-level, and but for the raging trade winds, which carried away 

 all winged insects as soon as disturbed, more specimens if not species 

 would have been collected. Here the vegetation is very different. 

 Up to about 9000 feet there is a varied scrub ; the Mamane, a forest 

 tree, becomes reduced to little more than a creeper ; the " Puakeawe " 

 (Cyathodes) and the " Ohelo " (Faccinium) with its edible berry and 

 dense growth of lichen, cover large tracts of ground. In places wild 

 strawberry {Fragaria chilensis) and the creeping Coprosina, with a 

 black berry beloved of the " Nene " {Bernicla sandvicensis) , are 

 abundant, but the goose is now almost, if not entirely, extinct on this 

 Island, though still found on the uplands of Hawaii. At about 8000 

 feet and upwards Geranium tridens, a lovely plant, with silver triden- 

 tate leaves, and Baillardia menziesii are conspicuous ; above these 

 there is little save tufts of grass and unattractive fern, excepting the 

 superb " silver-sword " {Argyroxiphidium), now mostly destroyed by
