Mosquito Eggs XXIX Genus Ho&&a Theobald

The eggs on whicp65 he following description is based were briefly described by McCrae and Sempala. They are here described more fully and illustrated for the first time. They were laid in the laboratory on several different occasions by wild caught females from Zika, near Entebbe, Uganda. Females of the African species of this genus cannot be identified with confidence and as all four Afri-can species are known to occur at Zika the present eggs are described as those of one or more unidentified species. By far the commonest males found at Zika are those of H. sanguinae Theo. and H. nigeriae Edw. Hodgesia sp. indet. The following description is based on eggs laid during July to September 1969.

Few if any eggs were laid when only dam
