pylotheca macrocarpa (Gray) Hbd. on the Manoa Cliff trail on 
Mt. Tantalus, Oahu. 
It is distinguished from other species occurring here except 
Aphis bambusae and the following species on Scirpus by hav- 
ing secondary sensoria on the third to fifth antennal joints and 
from bambusae by the greenish-yellow color of the apterous 
phase which lacks a white waxy secretion and by the longer 
cornicles which are about as long as in Aphis medicaginis. 
11. Aphis sp. 
A yellow species on Scirpus maritimus L. was taken by Mr. 
Swezey in April, 1913, at Kewalo, in Honolulu. In many ways 
it is close to the preceding species on Campylotheca, but the 
antennae of this species are longer and wholly yellow, whereas 
the last four joints are black in the other species. 
12. Aphis swezeyi Fullaway. 
This species recorded by Fullaway on Gnaphalium sp. has not 
been collected since. 
13. Aphis bambusae Fullaway. 
Melanaphis bambusae Van der Goot, 1916, Zur Kenntniss der 
Blattlause Javas, p. 61. 
This species was found by Fullaway on a bamboo which was 
believed to be a species of Phyllostachys. It has been wrongly 
accredited to Kirkaldy by Van der Goot, and more recently by 
Baker. 
14. Brevicoryne brassicae (Linnaeus). 
The cabbage Aphis occurs here rather sparingly on cabbage 
(Brassica oleracea L.) and kale (Brassica sp.), and is some- 
times found on Capparis sandwichiana D C. 
15. Toxoptera aurantii (Fonscolombe). 
This species is found commonly in the mountains of Oahu, 
generally at an elevation of 1500 to 2000 feet on various species 
of endemic trees and shrubs of which the following have been 
noted, although the list is by no means complete : Scaevola 
chamissoniana Gaud., Pittosporum glabrum Hook. and Arn., 
Hibiscus arnottianus Gray, Pelea sp., and Straussia sp.
