at Chapaira in June, 1910. Second liberated at Catacaos in August, 

 1910. 



Japan — Three shipments of the coccinellid beetle, Chilocorus si?nilis^ 

 the first using Hemichionas'pis aspidistrce and the other two Diaspis 

 pentagona; and one shipment of Diaspis pentagona containing Azotus 

 n. sp. near capensis and what was probably Arrhenophagiis chionaS" 

 pidis. The first coccinellid shipment, containing about 100 living 

 beetles, was liberated at Catacaos in November, 1910; second, con- 

 taining only three or four living beetles on arrival, was liberated in 

 March, 1911, at Coscomba; third arrived with all beetles dead in 

 August, 1911, and was put out at Coscomba. The parasite shipment 

 was liberated at Coscomba in March, 1911. 



Barbados — One shipment of H. minor, containing many Arrheno- 

 phagus and other parasites. Liberated at Catacaos in ^lay, 1911. 



The thanks of the Peruvian government are due to The Honorable 

 Commissioner of Agriculture for the West Indies, for the Barbados 

 shipment; to Mr. S. I. Kuwana, Imperial Entomologist of Japan, for 

 the Japanese shipments; to Dr. L. 0. Howard, Chief of the United 

 States Bureau of Entomology, for the Washington shipments; and 

 to Prof. Ch. Deneumostier, Director of the Escuela Nacional de 

 Agricultura y Veterinaria, for the Lima shipments. 



These shipments, though received at great disadvantage due to 

 lack of proper facilities, have undoubtedly borne important fruit. 

 Various species additional to those enumerated and quite certainly 

 contained in them have not yet been recovered in Piura, but may 

 nevertheless be found established there in the future, as the result 

 of these liberations. 



Thanks are also due to Mr. E. E. Green, Government Entomologist 

 of Ceylon; to Mr. Charles P. Lounsbury, Government Entomologist 

 of South Africa; to Mr. H. A. Ballon, Government Entomologist of 

 Barbados; to Mr. F. W. Urich, Government Entomologist of Trinidad; 

 and to Mr. E. M. Ehrhorn, Government Entomologist of Hawaii; all 

 of whom sent valuable material of Hemichionaspis to assist in the 

 preliminary search for suitable parasites; and to Mr. E. K. Carnes, 

 Superintendent of the California State Insectary, who sent material 

 from California. 



During 1910 and 1911 one hundred and more different shipments 

 of H. minor containing parasites were made between various points 

 in the infested region of Piura, for the purpose of distributing the 

 different species of parasites as evenly as possible through both the 

 Chira and Piura valleys. Important results are already visible from 

 this work, and further results from these shipments will no doubt ap- 

 pear as time goes on.
