Of the remaining 100,000, I sent 15,000 to Kauai and about 
80,000 were distributed on Oahu, selection being made of the 
plains and higher valleys, reinforcing some of the colonies liber- 
ated last month. In such large shipments we must necessarily 
expect quite a percentage of dead ones, and I should estimate 
these at about 5,000. 
A further shipment of material containing the parasite of the 
cabbage butterfly, Pteromalus puparum, has been received and 
the following distributions made of both sendings : 
215 parasites liberated at Wahiawa and Leilehua. 
575 parasites liberated at Honolulu and vicinity. 
From the first lot of parasites received we made a successful 
check test of breeding in the laboratory. We find that it takes 
from 14 to 15 days from the time the parasite deposits its eggs 
in the pupa of the cabbage butterfly until the new parasites issue 
again. This is indoors and no doubt in this climate the same or 
very nearly the same time will be necessary for outdoor breeding. 
Preparations have been made for further rearing of parasites in 
the laboratory so as to enable us to continue distribution. Owing 
to the delicate structure of these parasites no attempt was made 
to send any to the other islands, but we shall be able to do this 
later on. 
In my report of January I mentioned to Mr. Koebele the neces- 
sity of searching for some of the parasites received in previous 
years so as to know which have actually established themselves. 
I desire to report that during the liberation of the Hippodamias 
I took the opportunity of search offered and am pleased to re- 
port that we found two species of ladybirds, Asya luteipes, which 
were liberated about July, 1908, and Hyperaspis pocosa, which 
was also liberated in 1908. Both these are scale destroyers and 
a very good addition to the many beneficial insects we now have 
with us. They had not been collected before. 
Nothing further has been received from Mr. A. Koebele, and 
Mr. O. H. Swezey is continuing the breeding of the hornfly 
parasite which we last received and which is, to say the least, 
a very slow process. 
Owing to the late arrival of the Enterprise at Hilo I have not 
received Bro. Newell’s report up to this writing, but should it 
arrive before the meeting of the Board I shall attach it to this. 
Very truly yours, 
Edw. M. Ehrhorn, 
Superintendent of Entomology.
