of the Sugar Planters’ Station, collected at Lahaina, Maui, Sep- 
tember 27, 1905 (Swezey), which was without doubt parasitized 
by this species, this aphid being commonly attacked by it; it was 
reared from the cane aphis at Hilo, Hawaii, September 16, 1913 
(Swezey); and on May 22, 1918, the writer found the corn 
aphis (Aplus maidis Fitch) parasitized by this species at Grove 
Farm, Kauai. 
86. Aphelinus gossypii Timberlake. 
The ‘oldest specimen of this species that I have seen was 
taken in Honolulu on November 22, 1904, by Mr. Swezey, and 
the species was taken also at Kilauea, Hawaii, by Mr. Perkins 
in July, 1906. 
87. Aphelinus semiflavus Howard. 
Of this species, I have reared three specimens from material 
collected on Tantalus, Oahu. From To-voptera aurantii (Fons- 
colombe), I obtained two females on February 29, 1916, and 
one female on March 30, 1908, from Aulacorthum circumflexum 
(Buckton). 
88. Aphytis diaspidis (Howard). 
Recorded by Kotinsky in 1905 as Aphelinus fuscipennis from 
Mokuleia, Oahu, and in 1913 by Fullaway as Aphelinus dias- 
pidis, but taken in Honolulu by Koebele as early as January, 
1899 (U. S. Nat. Mus.). I have seen specimens only from 
Honolulu. 
89. Aphytis limonus (Rust). 
The Aphelinus species incidentally recorded by Girault in 
1913 from Honolulu proves to be this species, together with a 
few specimens of diaspidis. These specimens were reared by 
Koebele, March 10, 1899, from an Aspidiotus on oleander in 
Honolulu (U. S. Nat. Mus.). This species was also reared in 
Honolulu by Mr. George Compere in January, 1899, from three 
different species of diaspine scales. Limonus was described by 
Rust in 1915 from specimens collected by Mr. Ehrhorn in 1911. 
It is a common species in Honolulu, but I have not seen it from 
any other locality.
