Notes on the Distribution and Habits of Culicidae in Central Abyssinia.

The purpose of this paper is to place on record my notes on the distribution of the mosquitos obtained by myself during an Expedition to Central Abyssinia made, in company with Mr. J. Omer Cooper, from September 1926 to January 1927. We were engaged in collecting insects of many Orders and some other animals, as well as plants, so that it was not possible to devote more than a limited time to Culicidae . Nevertheless, I purposely gave rather special attention to this family and got together a series of some 103 specimens of the adult insects, belonging to 13 (or possibly 14) species. Examples of each species were pinned immediately, when freshly killed, with fine pure-silver pins, while in a few places where large numbers of one species occurred the surplus specimens were placed in spirit. No detailed investigation of the larval or pupal stages was undertaken ; a few examples of these may later be forthcoming among the collection of aquatic organisms which are Mr. Omer Coopers special province, but they are not dealt with here.

Note on the Life-history of the Fig-tree Moth, Ocnerogyia amanda , Staud. (Lymantriidae)

The following notes are written in the hope of supplementing what has been already published on the life-history of the Fig-tree Moth. In particular, the length of duration of the separate larval instars does not seem to have been given before. The observations began with the finding, on 27th May 1928, of caterpillars and eggs on fig-trees at Karradah, on the left bank of the Tigris below Baghdad. They were continued mainly in the entomological laboratory of the Agricultural Institute at Rustam, a few miles away, and were perforce discontinued after 21st June, as I had then to leave Baghdad on a tour of inspection and, shortly after my return, I fell ill.
