TRIBE CALLIPTERINI. 
2. Myzocallis kahawaluokalani Kirkaldy. 
Kirkaldy, 1907, Proce. Haw. Ent. Soc. 1, p. 101. 
This species has not been found since Kirkaldy’s description 
was published in 1907, and is unknown to me. It was described 
from specimens taken on the crepe myrtle, Lagerstroemia in- 
dica L., and was reported by Kirkaldy to occur on other shrubs 
in Honolulu, the identity of which was not made known. 
TrisE APHINI. 
3. Anuraphis helichrysi (Koch). 
Aphis myosotidis Fullaway, 1910, Ann. Rep. Haw. Agric. Exp. Sta. 
for 1909, p. 42. 
This is the common species on Erechtites, and is sometimes 
found on Gnaphalium purpureum L. Both of these plants are 
introduced weeds, and the aphid, therefore, has no economic 
interest. It is known to occur on Oahu, Kauai, and Maui. 
4. Aphis sacchari Zehntner. 
This species is common throughout the Islands on sugar- 
cane (Saccharum officinarum 1.) and sometimes occurs in large 
infestations, but is generally a pest of minor importance due to 
its control by predaceous enemies. Mr. Fullaway found a colony 
on sorghum (Andropogon sorghum Brot.) in Honolulu in 
August, 1916, but its occurrence on this plant is evidently rare. 
5. Aphis maidis Fitch. 
This is a very common species on corn (Zea mays L.), 
various varieties of sorghum, Sudan and Tunis grass (Andro- 
pogon sorghum Brot.), wonder forage grass (Andropogon 
sp.), pearl millet (Pennisetum glaucum (L.) R. Br.), and 
Guatemala grass (7Tripsacum laxum Nash.). It has been found 
in the Islands also on the following non-cultivated plants and 
weeds: Club rush (Scirpus maritimus L.), Job’s tears (Coixr 
lacryma-jobi L.), goose grass (Eleusine indica Gaertn.), fox 
tail grasses (Chaetochloa lutescens (Weigel) Stuntz and C. ver- 
ticillata (L.) Seribn.), crab grasses (Syntherisma pruriens (Trin.) 
Arthur and S. sanguinalis (L.) Dulac), and barnyard grass 
(Echinochloa crusgalli (L.) Beauv.).
