APHIDID® OF GEYLON. 715 
life History—tThis interesting species was discovered by 
Mr. Rutherford on May 11, 1914, feeding on the young foliage 
of Mesua ferrea. Only a few winged individuals could be 
collected at that time. 
The species is preyed on by Syrphid larvee and parasitized 
by an Aphidius, spec.; the parasitized insects are black in 
colour and somewhat circular. 
Locality —Peradeniya. 
Shivaphis ecelti, Das.—A number of winged females and a 
few wingless ones were observed by Mr. Rutherford on the 
under surface of leaves of Celtis cinnamomea. The insects 
are very conspicuous owing to their white waxy coating and 
the large amount of a yellowish liquid (honey-dew) which 
they secrete. The same species has been found by Mr. B. Das 
in the neighbourhood of Lahore (British India). 
Locality —Peradeniya. 
Oregma insularis, v.d.G.—Of this species a number of 
wingless individuals were collected on the under surface of 
leaves of bamboo (Dendrocalamus  strictus). The colonies 
were attended by (cophylla smaragdina, the red ant. The 
same species is fairly common on bamboos in Java. 
Locality — Peradeniya. 
Oregma minuta, v.d.G.—Some alate and apterous females 
of this species were observed on the under surface of leaves of 
Dendrocalamus strictus, where they were attended by small 
blackish ants (Cremastogaster, sp.). 
Locality —Peradeniya. 
Cerataphis lataneze, Boisd——A large number of apterous 
females were found on the inflorescences of an Areca palm. 
Locality —Peradeniya.
