MEXICO AND CENTRAL AMERICA. 



1. Mr. Robert Newstead, of the Liverpool University, re- 

 ports tlie following: A scale bug {Aspidiotus cydoniae, Comst.) 

 on Castilloa from Nicaragua. 



This scale bug is quite common in this Territory on guava 

 and other plants, but thus far not reported on rubber. It is also 

 well kept in check by parasites. 



2. A long-horned beetle {Taeniotcs scalaris, Fab., var. 

 snturalis, Thorns.), a borer on Castilloa from Nicaragua was 

 reported by the same author. 



3. A scale bug closely allied to our black scale above (Platy- 

 saissetia castilloas) was collected on Castilloa in Mexico by Prof. 

 C. H. T. Townsend. 



4. The Manihot scale {Lccaniodiaspis luanihotis) was col- 

 lected by the same person on "Nettle tree" (presumed to be a 

 species of Manihot) in Mexico. 



SINGAPORE AND INDIA. 



Upon material recently examined, which w^as kindly submitted 

 to me for study by the Sugar Planters' Station, and collected by 

 Mr. Muir in Singapore, and labeled ''rubber," two species of 

 armored scale bugs were identified. 



1. Aspidiotus palmae, Morg. & Ckll. 



The species has not hitherto been reported from rubber, but 

 it seems to be very common in the vicinity of Singapore as it was 

 collected there by Mr. Muir on a variety of plants. 



2. Chionaspis dilatata, Green. 



This is one of the Snow scales and only a few specimens were 

 found on the material studied. 



3. A termite or white ant to be referred to under Ceylon is 

 reported very destructive to rubber trees in India. 



CEYLON. 



The largest number of insects known to attack rubber is to be 

 found in Ceylon. This fact does not necessarily indicate that 

 Singalese rubber trees are most affected. Our knowledge of 

 Singalese rubber insects may be more extensive merely because 

 they were studied by a competent entomologist.
