of plants. The following number of insects by genera were 

 found : 



Beetles 19 genera 



Butterflies and Moths 7 genera 



Ants 6 genera 



Scale Insects 14 species 



Plant lice 6 species 



Various 8 species 



One lot of small Hermit crabs, said to feed on vegetables in 

 Japan, were taken from a passenger who was taking them as 

 playthings for his boy. Four species of fungi were destroyed 

 on fruits and plants arriving in the baggage of passengers. 



Breeding and Distribution of Parasites. Mr. D. T. Fullaway, 

 who has charge of all this work, left the Territory in July for a 

 trip to Java, India and the Philippines in search for parasites for 

 the Melon fly (Bactrocera (Dacus) cucurbitae) . Previous to his 

 departure he attended to all the breeding and distribution of the 

 various parasites of the Fruitfly and Horn, Stable and Houseflies 

 which were obtained from the first and second expeditions to 

 Africa. During his absence, since July, this work has been kept 

 up under my direction by my assistants. During the year there 

 were liberated in round numbers 204,664 parasites of the fruit 

 fly, consisting of six species, Opius humilis, Diachasma fidlawayi, 

 Diachasma tryoni, Tetrastichus giffardii, Dirhinus giffardii and 

 Galesus silvestrii. Of these species the first four have been found 

 established in the open and have been reared from fruit gathered 

 from various localities. The two last named species, although 

 thousands have been liberated, as yet have not been recovered 

 either in the open or bred from gathered fruits. 



In the control of the Horn, Stable and House fly there were 

 liberated, in round numbers, 51,850 parasites in many districts on 

 all the islands. From material taken in the field we have been 

 able to rear all the species liberated, namely, Miiscidiftirax vorax, 

 an undetermined African spalanqia, an undetermined Philippine 

 spalangia and an undetermined Philippine Ptcromalid. 



Respectfully submitted, 



E. M. Ehrhorn, 

 Superintendent of Entomology.
