The insect by préférence attacks young leaves, which for 

 the greater part are destroyed by it, the mine drying eut to a 

 large brown patch, which looks as if it were burnt. 



For the pupation, a well sheltered place is chosen either at 

 the underside of a leaf or in a ridge of the bark. The pupa is 

 protected by an oval-shaped flat cocoon of silky appearance, from 

 which the moth escapes in the saine way as in other Qracilaria 

 species, by piercing it and leaving the skin of the pupa in the hole. 



IX. CINOHONA. 



Pachypeltis spec. The genus Pachypeltis, although closely 

 allied to Helopeltis, may be immediately distinguished from the 

 latter by the absence of the scutellar spine. In this country it 

 is represented by several species, one of which has shown itself 

 noxious to cinchona-trees in the same way as the well known 

 „Mosquito-blight". 



The insect is shiny black above with a yelloAV line one the 

 scutellnm and a yellow ring on the femora. The underside of 

 the abdomen is creamy white with black markings. 



X. PIPER NIGRUM. 



1. Elasmognathus spec. Numerous spécimens of an Elas- 

 mognathus species (family Tingidae), very much allied to E. greeni, 

 Kirby, were received from Sintang (Bornéo), where they are 

 said to do some damage to the pepper plants. 



Further détails were not available, but it is very probable 

 that the insects bave proceeded in the same way as the above 

 named, Ceylonese species of which Mr. E. E. Green, the well- 

 known entomologist of that country, writes (as quoted in the 

 „Fauna of Britisch India", Rhynchota, Vol. II, pag. 142): This 

 species punctures the leaves of the cultivated pepper-vine (Piper 

 nigrum). It makes the leaves look spotted with brown along 

 the line s of the main veins but does not appear to seriously 

 injure the health of the plant. The insect feeds on the under 

 surface of the leaf. It occurs both on cultivated und wild pepper 

 throughout Ceylon.
