the tropics. Its life-history and food-plants have already been noticed 

 [R. A.E., A, i, 517]. There are three or, at the most, four generations 

 a year, the most destructive brood appearing in August and early 

 September. In favourable seasons each generation becomes more 

 destructive and numerous than the last. Aestivation is passed in 

 the pupal stage. Maize is attacked in the same way as by Heliothis 

 obsoleta (armigera), the young caterpillars eating the tender sheathed 

 leaves and the older ones the forming ears. 



Preventive measures include clean cultivation and rotation of 

 crops. An effective poison bait placed at the base of the food-plant 

 consists of 60 lb. bran, 1 lb. Paris green or London purple, the pulp 

 and juice of three oranges, ^ gal. molasses and 3| gals, water. The 

 fields should be cleared of grass and weeds, and the application carried 

 out in the late afternoon or after sunset. Dusting is ineffective unless 

 the food-plant has a broad leaf surface. If this must be practised, 

 lead arsenate is recommended, as there is a risk of scorching with Paris 

 green or London purple. Furrows may be dug round a heavily 

 infested area and the caterpillars massed in them destroyed by burning 

 or spraying with kerosene. Wliere the moths are collected at light 

 traps, the majority of the females will be found to have already deposited 

 their eggs. In Jamaica the natural enemies include the parasites, 

 Frontina aletiae, Archytas piliventris, Henicospiliis purgatus, Chalets 

 fohusta and SpilocJialcis'femorafa, and the predacious Carabid, Calosoma 

 lateraJe.

The fungi dealt with in this paper were collected in Natal and 

 comprise : Empusa muscae, attacking Muscid flies ; E. conglomerata, 

 attacking the imago of the Tipulid, Nephrotoma iimbripennis, Alex. ; 

 E. grylli, attacking Orthoptera and, according to Thaxter, Lepidoptera 

 and Diptera also ; Entomophthora aphidis, effectively checking several 

 species of Aphids ; E. megasperma, attacking larvae of Euxoa segetis, 

 Schiff. ; and E. apicnlata, attacking the following : Lepidoptera — 

 imagines of the Noctiiid, Lycophotia muscosa, Geyer, and larvae of 

 Pachypasa capensis ; Diptera — imagines of a large Anthomyiid fly 

 and of Nephrotoma unicingulata, Alex. ; Coleoptera — imagines of 

 Trochalus fulgidus, Fhs., and Adoretus ictericus, Burm. ; and Rhynchota 

 — adults of the Cercopid, Locris arithmetica.
