In the following descriptions I have dealt mainly with part of a small but valuable collection of Coccid Chalcids, sent by Mr. W. H. Patterson from Aburi, Gold Coast. The excellent condition in which the insects were received may be due to some extent to the fact they were bred specimens, but it also owes something, I think, to the method of packing employed. Into each tube (1¾in. × ½ in. ) a little melted naphthalene had been run with a piece of moderately thick paper on the top ; above this again the Chalcids were loosely enclosed in screws, or (in the case of minute Eulophids and Aphelinines) in small triangles of tissue paper, and the tube coated and sealed with paraffin wax.
