siderably less rainfall than the North Coast.

Trinidad, 3. 7. I. 
The sugarcgne ; butterfly ( Calisto nulchellus Lathy) was observed on 
July 29 heavily infesting about three acres of sugarcane in a very damp 
situation near Cape Haiti in Limbe Valley. Almost every leaf was more or 
less eaten by the caterpillars. 
The brown ant Solenox)sis geminata Fab. Was observed on July 31 to have 
killed about 20 per cent of the young grapefruit trees (planted in January) 
on 200 acres at Ca-oe Haiti by ringing the bark at the base. 
An undetermined mirid (reddish adults) was observed on July 29 injuring 
a small patch of upland rice between Cape Haiti and Limbe. The bug was 
abundant in spots, causing a yellowish or whitish mottling of the leaves, 
and the infested patches were considerably stunted. The same insect was 
also present in two other localities far from rice, on the grass Pa rp alum 
distichum , which is probably its natural food plant. 
A black .-and spiny pentatomid bug was present and breeding on a small 
patch of upland rice between Cape Haiti and Limbe.
