Root Boi:er of review Mr. Jemmett .spent his time in travel, and in becoming familiar with the conditions in the agricultural districts of the country in which he is working. Mr. .femmetl's report gives a sum- mary of the important insect pests, and emphasizes the need of an immense amount of entomological work in South- ern Nigeria. A classification of insects according to economic concern is given, and notes on a few of the most impor- tant insects noticed in 1909. It is of interest to note that the nature of the attack on several tropical crops such as cacao, cotton, maize, cocoa-nuts, etc., is the same as in the West Indies. The insects are not identi- fied, so it cannot be stated whether they are of the .same species as the West Indian forms. In addition to the annual report, Mr. Jemmett has issued a preliminary report on the insects affecting maize, a report on those observed on cotton, iLs (Calandra spp.). ^nd one on insects found on cacao in 1909. Maize seems to be attacked by two kinds of insects: one the grain weevils, the other lepidopterous larvae. The lepidopterous larvae would seem to be similar to the boll worm {I/ili'it/iis o/jsoleta) and the corn ear worm {Laphy(/i)ia ) in the manner of attack on the corn. The caterpillars of the corn, in Southern Nigeria, tunnel into the stem of the plant and the ripening ears of the grain, and since they occur in large numbers they are able to cause a very large amount of loss to the farmers. The grain weevils {Calandra granaria and C. ori/:ae) are of very general occurrence in many parts of the world as.
