The object of this paper is to supplement an article which appeared early in 1914 in the Journal of the Board of Agriculture of British Guiana (Vol. iii, No. 3.) At that time it was proposed to publish a further account of these insects as soon as more species had been collected and identified, and fuller information gained. Also, taking into consideration the great economic importance of the Coccidae, it has been deemed advisable to disseminate as widely as possible all information which has been acquired concerning them locally. In the previous article, some fifty-one species were enumerated and notes recorded concerning their habits and economic importance. In this paper information appertaining to sixty-eight species is given, a number of which are new to science. Further knowledge with regard to the parasites and predaceous enemies has been gained, as well as their economic status.

British Guiana has not been invaded by migratory locusts since the year 1886, when, as far as it is possible to ascertain from the records of those bygone days, the same species of locust was implicated. Also, on the occasion of this previous attack, it seems very probable that a swarm first infested the North West and Pomeroon areas and, multiplying there, migrated further down the coast to Berbice.
