from Fiji" thickly plastered with what we have definitely 

 ascertained to be the above named scale insect. The author 

 of this species reports it to have completed the destruction of 

 the coffee industry in Ceylon in course of some 10-20 years. 

 As but one or two of the numerous specimens received showed 

 signs of having been parasitized and as the plants were located 

 in the very midst of the coffee center on these Islands, and as 

 moreover, the insect is known to infest also rubber, guava and 

 other plants immediate action became imperative. 



It was subsequently ascertained that three years ago this 

 •month a half dozen plants were imported from Fiji. While no 

 scale Avas observed upon the leaves Avhen collected for us, it 

 was probably observed on previous occasions, but owing to its 

 strong resemblance to immature coffee scale (Piilvinaria psidli, 

 Mask.) its identity was not suspected. Other citrus plants were 

 found growing upon the premises and it is fortunate that the 

 Fiji lemons were considerably removed from them and sui-- 

 roujided by other vegetation. A careful examination of these 

 plants revealed only two of the lot infested with green bug, 

 the others being absolutel}^ free from it. Some distance away 

 was a lemon tree about twice the height of the Fiji specimens, 

 origin unknown, quite thickly infested wdth both the coffee 

 scale and green bug. A large number of the mature scales were 

 killed by parasites, the exit of one of which was observed and 

 the insect captured. Some material for breeding of parasites 

 and the collection were saA^ed, the trees themselves having been 

 up-rooted and burned before I left the district. The third in- 

 fested tree above referred to proved quite a puzzle for a while 

 as it was suspected of having come from another resident of 

 the district in which case Fiji, as the original source of the bug, 

 was not altogether certain. A careful study of the vegetation 

 on the premises of this other resident, however, dispelled the 

 fear that the bug was generally scattered. I failed to find it 

 there and furthermore established that the third infested plant 

 did not come from there. With the object of ascertaining the 

 possible distribution of the bug, all varieties of plants liable to 

 infestation by it were examined all along some 16 miles of 

 Government road in Kona, as well as the premises of the plant- 

 •ers visited, but the insect was no where found.
