this if it existed in any nursery of the State. It has also been found 

 in Georgia, and Mr. Cockerell reports it to be a very general feeder in 

 Jamaica, and on the Island of Trinidad, West Indies, it is a serious pest. 

 This would lead me to believe that the West Indies is not its natural 

 habitat, and if any relief is to be obtained from natural enemies of this 

 pest we must look to Japan for them. As Mr. Albert Koebele intends 

 visiting Japan, in the interest of the Hawaiian Government, to look up 

 the natural enemies of the beetle Adoretus umbrosus, that is doing so 

 much damage in the vicinity of Honolulu, I will write and ask him to 

 kindly investigate this species and its parasites in that country. This 

 scale appears, by Professor Howard's report, to have three or four genera- 

 tions annually. It resembles somewhat the rose scale (Diaspis rosse). 

 The narrow white male scales usually predominate and look like fine 

 lime on the branches. It would be well for orchardists and Quarantine 

 Guardians of the State to make a close inspection and report any sus- 

 picious case. This scale is easily killed with hydrocyanic acid gas, and 

 fumigation is the only method that should be used to combat it, unless 

 where it has only a limited spread, and in this case the ax and fire are 

 the best remedies. Specimens of imported trees infested with this scale 

 are on exhibition in our cases. 



The dangerous orange scale (Mytilaspis gloverii) was found on a new 

 food plant (Magnolia fuscata) from Japan, on August 18th. The stem 

 and branches were as thickly covered with this pest as I ever saw on an 

 orange tree. This will show the danger to the citrus orchards of the 

 State from the introduction of this pest upon ornamental stock. A 

 section of the stem was saved as a cabinet specimen and the tree 

 destroyed. 



A lady passenger that arrived on the steamship " Be] gic," August 28th, 

 from Japan, was very indignant because I destroyed a number of 

 crickets (Gryllidse), that she brought from Japan, and intended taking 

 to Pleasanton, Alameda County, as pets. They were very comfortably 

 housed in an artistic split bamboo cage. She endeavored to soften my 

 apparent lack of feeling by the statement that she had bestowed so 

 much care upon them on the voyage by supplying them daily with fresh 

 lettuce and other green food. But this did not save her pets, as the 

 people of this State have no desire to experiment with such insects for 

 the sake of their song. 



On August 25th the steamship "Australia," from Honolulu, had 

 three boxes of plants for Mrs. Garcia, of San Leandro. Three orange 

 trees were infested with a species of Dactylopius that produced contor- 

 tions and swellings upon the twigs, stopping their growth and causing 

 other shoots to start below the point of attack. The trees were de- 

 stroyed. Specimens of the twigs were saved. 



Plants infested with insects referred to in previous reports and new to 

 this State have been found at different times and destroyed. 



Since my last report I have spent considerable time in the extensive 

 orchards of President Cooper, at Ellwood, near Santa Barbara, and 

 under his instructions have sent out 825 colonies of the three species of 

 Rhizobii — ventralis, debilis, and toowoombse — that have been so successful 

 in ridding his trees of black scale. R. ventralis was by far the most 

 numerous, and the colonies consisted principally of this species. The 

 reports received indicate that the beetles had reached their destinations 

 in nearly every case in splendid condition, and had gone to work upon
