The family of the Trypetidæ is of great economic importance, for among its numerous genera are to be found many pests of the orchard and farm. The flies of this family are rarely brought to the notice of Europeans in West Africa, for there farming operations are entirely in the hands of the native population and the amount of damage done by these insects is perhaps insufficiently appreciated by Europeans; but from observations made in my own gardens, during a long West African experience, I believe the loss caused by their attacks must be considerable. The flies which are responsible for the damage observed belong to two genera—Ceratitis, MacLeay, and Dacus, Fabricius.

Throughout the Nyasaland Protectorate there are many areas which are infested by Glossina morsitans; and this species is also to be found in North Eastern Rhodesia, and in German and Portuguese territory bordering on Lake Nyasa. I have been frequently through all these territories during the last 22 years, and know them well.

In the Bulletin of Entomological Research, Vol. I. pp. 60–61, I gave an account of the ravages of a cocoa bark-sapper (Sahlbergella theobroma, Dist.), which was found destroying cocoa trees upon plantations in some parts of the Gold Coast and Ashanti, where, by reason of its wide distribution in 1909, it promised to affect the industry seriously.

At the suggestion of Mr. S. A. Neave, I have prepared the following brief notes of my observations on the changes in the distribution of Glossina morsitans within the Lundazi District.

Mr. C. C. Gowdey, the Government Entomologist of Uganda, is to be congratulated upon the number of interesting forms which he has forwarded to this country for identification from time to time. Many of the species, if not all, are of economic importance, and, judging by their numbers, must have sorely taxed the plants upon which they were found.

In Prof. Newstead's paper “On Scale Insects from the Uganda Protectorate” (Bull. Entom. Res. Vol. I. pt. 1) is a description and figure of the male larva of Stictococcus dimorphus. This remarkable larva is said to have no mouth parts. It is also unique in differing completely in form and structure from that of the female larva of the same species. Its anal aperture is not only in a different position, but of a different character—having a setiferous ring similar to that of the Dactylopiinæ. Stictococcus is (rightly or wrongly) placed in the subfamily Lecaniinæ.
