In the baggage of the Chinese immigrants some sweet potatoes 
infested with the sweet potato borer, Cylas formicarius, were 
found and were destroyed. This pest is already well established 
in the Islands, but one never knows where the baggage is going 
and it is best to prevent the dissemination of the pest into new 
sections. 
At the port of Hilo the following report of inspection was re- 
ceived : 
Seven vessels were boarded and the total of 105 lots contain- 
ing 1,080 parcels were examined. Nothing containing insect 
pests or fungi was found. In the future the inspector will give a 
more itemized account of the work, as it is most important to 
know just what fruits and vegetables are being shipped into the 
country. During the month Brother Newell paid the Division a 
visit and I had an opportunity to go over the work with him ; he is 
very desirous of having me visit his district soon and I hope that 
I can manage to do so. 
During the month Mr. George Compere, who has been collect- 
ing beneficial insects in the Philippines, passed through Honolulu 
on his way to California. I am pleased to state that I was able 
to give Mr. Compere some assistance in collecting food, mostly 
Mealy bugs and Cottony Cushion Scale as food for the various 
ladybirds he is taking to the Coast. Mr. Compere mentioned the 
existence of a parasite for the Alligator Pear scale. Pseudococcus 
nipae, at Manila and I shall communicate with the Department 
of Agriculture there and see to what extent the pest is kept in 
check and if arrangements can be made to procure the same. 
Two sendings of parasites, Pimpla behrensii, have been re- 
ceived from Mr. J. P. Baumberger, who is collecting for our Divi- 
sion under my directions in California. We are in hopes that 
these parasites will help reduce the ravages of the Cocoanut leaf 
folder, Omiodes blackburni and other caterpillars infesting some 
of the truck crops of the Islands. The one species of Pimpla we 
have in the Islands is doing excellent work in the reduction of 
caterpillars and more species will naturally greatly add to the 
efficiency of the work of those already with us. 
BENEFICIAL INSECTS DISTRIBUTED. 
Captain Piltz of the “Florence Ward” called upon me during 
the month and stated that he feared the Hornfly Haematobia 
serrata was at Midway Island and wanted some parasites for the 
same. After making many inquiries about the flies observed by 
him and after consulting with Mr. B. W.. Colley, the local agent, 
we are doubtful whether the Hornfly exist there. We, however, 
have been able to send parasites of the Stable fly, Stomoxys cal- 
citrans, and the House fly, Musca Domestica, and have asked the 
agent to collect specimens of the various flies for our e*xamination 
so that we shall definitely know what flies really exist on Midway
