but ii few .stul)s. They appeared to prefer t»eraiiiuin to any other 

 plant oTowing- in houses there, and they alwa3^s came under observation 

 in winter. The species was kept in check to a considerable extent by 

 turning the plants out of their pots and picking out such grubs as 

 could be seen and killing- them, and by digging up and picking- out the 

 grubs from the dirt in the benches. 



Mr. C L. Marlatt of this office informed the writer that this species 

 caused injury in lemon g-roves near San Diego, Cal., during July, 1900, 

 and that in that portion of the countr}' it is known as an occasional 

 pest, having been established there for a number of 3'ears. 



A similar report of injury in the same locality was received from 

 Mr. G. P. Hall, April 19, 1899. 



OCCURRENCE IN THE HAWAIIAN ISLANDS. 



During February, 1901, we received specimens of this species from 

 Mr. Albert Koebele, at present stationed at Honolulu, H. I., with 

 notes upon its habits. These specimens have been compared with 

 authenticalh' determined AraialgiDi fidhrl by the writer, as well as by 

 Mr. Schwarz and Mr. Charles Fuchs, and there is no doubt of their 

 identity. It seems that the species is known in Hawaii as the Olinda 

 l)ug-, and has been described by Mr. V. R. Perkins as Pandanioru)^ 

 ollndcE. Some notes are furnished by Mr. Koebele, which bear upon 

 the insect's life economy. Its presence has been frequently noticed 

 upon trees as well as upon Hilo grass. Many trees of Java plum 

 recentl}^ planted have been seen by Mr. Koebele with every leaf eaten 

 off, and some have died from the effects of the beetle and Hilo grass 

 combined. The insect appears to 1)e most numerous along the border 

 of forests, and is found from the seashore as high up as 5,000 feet 

 elevation. Seven years prior to the date of writing the beetle was 

 seen from Paia, where it was destructive to roses and garden plants 

 generally. Our correspondent believes that it must have been present 

 on the islands long- before it became prominent as a pest, and he as 

 well as Mr. Schwarz, the writer, and some others are inclined to the 

 belief that it is an introduction from Mexico — Mr. Koebele believes 

 probal)ly from Acapulco, l)ut docs not state reasons.

HISTORY AND LITERATURE OF THE SPECIES. 



Fullers rose beetle appears to have been ffrst l)rought to notice as 

 a pest in the year 18T9, when Peter Henderson pubUslied a four-column 

 illustrated article concerning- it in the "Gardeners' Monthly" for 

 March of that year (pp. 86, 87). 



This species furnishes an interesting example, analogous to that of 

 the so-called black aphis of the violet, of how long an insect can do
