I recently received from Mr. T. D A. Cockerell, Las Cruces, New Mexico, a minute parasite of a Ceroplastes on Euphorbia hypericifolia from the Red Hill district of Jamaica, which was transmitted to him by Dr. M. Grabham. Both genus and species prove to be new, and are printed separately, partly for the reason that my revision of the Aphelininæ of North America has recently been published and I do not expect to do any extensive work on the subfamily again for some time, and partly for the reason that Mr. Cockerell wishes to use the names in the Journal of the Institute of Jamaica.
