Enemies for melon fly can be had closer at home, Japan and 
China. It should be a comparatively easy matter to get them 
over. Why not have lots of cucumbers shipped over in bags 
laid in boxes so that larvae of melon fly could not escape. You 
would then breed parasites out. Most any Jap and Chinese mer- 
chant could do it for you. Have it from both places. 
Remember me kindly to Mr. Giffard. 
Ever yours sincerely, 
A. Koebele. 
Honolulu, T. H., January 27, 1910. 
Mr. Albert Koebele, Waldkirch i/Br., Baden, Germany. 
My Dear Koebele: — Your letter of December 14, 1909, came 
to hand and I note what you say regarding the shipments of 
parasites. It is really too bad that we have not had better re- 
sults and I am sure that Mr. Williams is doing all he can to help 
us. I know that while I was attending to these I very often just 
missed a boat and then had to place the shipment on ice for a 
week or ten days. I had a conference with Mr. Swezey about 
the matter and we both feel that it might be well for you to send 
your shipments direct to Honolulu as we think that six da 3 ^s 
longer would not materially interfere with the parasites, especi- 
ally as we find that the last shipments have been kept longer 
than that in San Erancisco waiting for boats. 
In regard to the shipment of the Hyperaspis species (Hyper- 
aspis 8-notata) which you sent to Kolinsky and of which you 
said that no report had been given, will say that I have looked 
up the record and find that two colonies were liberated, one at 
Mrs. Jaeger’s place and the other at Governor Cleghorn’s place. 
As soon as the warm weather sets in I shall personally investi- 
gate and see if any trace of this species can be found. 
In regard to the sending of Hister from Arizona, these were 
liberated by Mr. Swezey when received. 
I received two vials containing the scale insects you mention. 
The scale is Eriopeltis festucae, a common grass scale from 
Europe and Canada. I succeeded in raising a few Chalcids 
from these and turned them out on tree infested with Pulvinaria 
psidii. As Eriopeltis belongs in the Lecanium group the para- 
sites will probably attack such things as Antonina aiuDCero- 
plastes and Pulvinaria. 
We will inquire about the melon fly parasite in Japan and China 
and see what can be done regarding the shipment of maggot in- 
fested cucumbers. 
Very truly yours, 
Edw. M. Ehrhorn, 
Superintendent of Entomology.
