Microcerotermes parvus theohromae, Desn., Termes ostentans, F. Silv., 

 and Schedorhinotermes putorms, Sjost. ; and a borer, thought to be a 

 caterpillar of the genus Zeuzera. 



Considerable injury has been done by Pseudaonidia trilohitiformis, 

 the biology of which is briefly described. It attacks the leaves, but 

 a fungus, Microcera coccophila, first noticed in 1916, had effectively 

 checked it by 1918. The diffusion of this fungus by means of leaves 

 of Castilloa and small cacao plants was attempted. Insufficient 

 investigation does not permit of any opinion being advanced on the 

 value of another fungus, Myriangium duriaei, or of Ichneumonid 

 parasites. Neotermes gestroi lives within the living stems of cacao ; 

 it is the most dangerous of the termites and causes serious loss. Infest- 

 ation may be rapidly reduced by cutting off and immediately burning 

 the infested wood, the upper parts being the first attacked. A black 

 ant is a natural enemy of this pest. Microcerotermes parvus theo- 

 hromae and Mirotermes amaralii build their nests near the cacao stems. 

 Ceplialotermes rectangidaris makes a semi-subterranean nest near a 

 root or stem. Microcerotermes dolicJiognathus nests in the upper 

 branches. Termes ostentatus hves either imderground or in hills ; it 

 cultivates a fungus that has not yet been identified. 



The caterpillar attacking the green branches, stated above perhaps 

 to belong to the genus Zeuzera, makes a mine with a diameter of 6 

 milHmetres and a length of 16-39 inches. As a rule two-year-old 

 branches are infested, sometimes the trunks also. Only a few centres 

 of infestation have been noticed in the Island, and it is probable that 

 natural enemies keep this pest in check. Infested branches and stems 

 should be cut off and burned.
