Scale Bugs. (i). The Greedy scale {Aspidiotus camelliae)' 

 was collected in numbers on a Castilloa plant suffering from root 

 fungus. This scale bug is quite common in this Territory and 

 occasionally very numerous in the mountains on Ohia and Koa, 

 but not reported on rubber thus far. But in view of the pres- 

 ence of what are quite effective enemies it need not be feared. 



2. A species of Lepidosaphes (a scale allied to our purple 

 scale so common on citrus plants) was collected on Para (Hevea 

 brasiliensis) . 



3. Grasshoppers were observed nibbling off young plants in 

 the nursery. The occasional abundance of grasshoppers in this 

 Territory might result in damage to young plants in our nur- 

 series also if they are not protected*. We have, however, a num- 

 ber of parasites that keep these animals subdued and, if neces- 

 sary, we can readily check their work by means of a poison. 



4. A species of long-horned beetles (Moechotypa verruci- 

 collos, Gahan) was bred from stumps of Para rubber. This 

 group of insects is usually found to attack plants after their 

 vitality has been previously weakened in some way. In this in- 

 stance Mr. Green, who records the fact, has found that the plants 

 were suffering from a root and collar fungus (Botryodiplodia 

 elasticae, Petch.). 



5. Another beetle of this group (Pterolophia annulata, 

 Chevr.) was bred from young Ceara trees. It was also reported 

 from India where it actually ringbarks the trees. Mr. Green 

 thinks that it may prove serious, but from the habits of this 

 group as indicated above it would' be well to look into the health 

 of the tree previous to its being ringbarked. 



6. A number of bees and wasps were found to build their 

 nests in cavities of living rubber stumps or the pith of dead 

 twigs. It is quite possible that one of these bees or wasps find- 

 ing a cavity not wholly to its satisfaction will gouge out some 

 of the substance to increase it. This, of course, means a 

 wound, the escape of latex, an opening for the entrance of dis- 

 ease. It is well, therefore, to plug with earth all cavities and 

 to trim away dead twigs. In trimming it is wisest to cut at 

 the node else the cut surface will die down to the node next be- 

 low, w4th all attendant ills. 



7. The grubs of a cockchafer, (a beetle) were found to feed 

 on the roots of Hevea and particularly troublesome to young
