O. fullonica and 0. divitiosa are known in Rhodesia, as well as in India, 

 Australia, and the Malay Archipelago. The adults are able to pierce the 

 rind of various citrus fruits in order to feed on the juices within. The 

 moths were abundant in January and February 1915, but injury 

 decreased rapidly after March. The puncture becomes surrounded by 

 a decayed area and the fruit falls early. Certain varieties of orange, 

 especially Washington Navel, are more liable to attack than others. 

 Peach, plum, apple, banana, mango, grape and quince are also injured. 

 The method of protecting the trees by mosquito netting cannot be 

 apphed in large orchards. In Queensland, bananas of the Cavendish 

 type planted among citrus trees prove attractive to the moths ; this 

 variety will not grow in Rhodesia, but could be imported and the ripe 

 fruit himg among the trees. Adults visiting it could be collected or 

 destroyed by impregnating the bait with an arsenic compound. The 

 fohage of citrus trees is occasionally injured by the weevils, Sy states sp. 

 and Rhinosomphus {Periscopelta) mutabilis. Spraying with lead arsenate 

 at the rate of 3 lb. to 50 gals, water should prove an efl&cient remedy. 

 Two species of Coreid bugs have been recorded as attacking the fruit of 

 orange and green granadillas respectively, but cannot at the present time 

 be regarded as pests. Other occasional feeders on citrus are Chrysom- 

 fhalus hederae (oleander scale), on the over-ripe and green fruit and 

 fohage of lemon ; a soft scale, distinct from Coccus hesperidum, on 

 orange ; a species of mealy bug ; cicadas ; the Pentatomids, 

 Agonoscelis puberula and A. erosa ; two species of Tortricid moths ; 

 a boring Cerambycid beetle, and the fruit-flies, Ceratitis capitata and 

 Ceratitis sp.

 eridanus, Cramer. — Insecutor Inscitiae Menstruus, Washington,

The Arctiid moth, Ecpantheria eridanus, is common in the island of 

 Porto Rico and has a wide range of host plants. These include 

 Erythrina micropteryx, orange, Ipomoea sp., vanilla, banana, Cissus 

 ? sicyoides and Panicum sp. At the experiment station the larvae caused 

 some damage by feeding on the flower buds of vanilla. Eggs are laid 

 both by fertihsed and unfertihsed females, oviposition beginning one 

 or two days after emergence. The eggs are deposited in masses on the 

 upper leaf-surface, in the case of the orange. The incubation period 

 varies from six to eight days, and the larval period from 24 to 62 days. 

 Pupation takes place within a cluster of leaves or in a rolled leaf, and 

 occupies from 15 to 20 days. The larvae are attacked by the Ich- 

 neumon, Eremotylus angulatus, Hook., and by a fungus, probably 

 an Empusa.
