It also occurs on the following cultivated or escaped shrubs 
and trees: Coffee (Coffea arabica L.) and mango (Mangifera 
indica L). The record on mango is based on a small colony 
found at Kaimuki, May 24, 1920, which is the only time that 
the species has been discovered in the coastal lowlands, to the 
writer’s knowledge, except that a single-winged migrant was 
taken by Fullaway in October, 1922, on Jaora macrothyrsa 
Theijsm. and Binn. It has never been seen on Citrus in the 
Islands, probably because of its rarity in the lowlands, where 
most of the Citrus trees are grown. 
16. Vesiculaphis caricis (Fullaway). 
Toxoptera caricis Fullaway, 1910, Ann, Rep. Haw. Agric. Exp. 
Sta. for 1909, p. 32. 
Vesiculaphis caricis Del Guercio, 1911, Redia, 7, p. 464. 
This peculiar aphid was discovered by Fullaway on a sedge 
(Carex sp.) in the mountains back of Honolulu. 
17. Yamataphis oryzae Matsumura. 
Matsumura, 1917, Jour. Coll. Agr. Tohuku Univ. 7, p. 412. 
A single alate female was taken by me while riding on a 
street-car between Kaimuki and Moilili, in Honolulu on March 
24, 1924. This specimen agrees very well with Matsumura’s 
description, and I believe the identification is certain, notwith- 
standing the limited material on which it is based. The species 
was discovered by Matsumura at Sapporo, Japan, on the roots 
of rice (Oryza sativa L.). 
18. Myzaphis sp. 
The apterous phase of this species is sometimes common on 
cultivated rose-bushes in Honolulu, and was first noticed in 
1916, but the alate form was not discovered until March, 1923. 
In Theobald’s table of rose aphids (Bull. Ent. Research, 6, 
p. 112, 1915) it runs to neorosarwm Theobald, a new name. for 
rosarum Buckton (not Kaltenbach), but it is apparently not that 
species. According to Buckton, neorosarum has black marks on 
the abdomen in the alate phase which is not true of the Hono; 
lulu species, and the capitate hairs of the body are more nearly 
as in rosarum (Kaltenbach) as figured by Theobald.
