In connection with the study of Anopheline pupae with Dr. P. A. Buxton, I extended my comparisons to the Culicine pupae accessible to us, in the first place to discover their differences from Anopheline pupae, and in the second to bring the Culicine pupae themselves into a system. As with the Anopheline pupae, I limited my comparisons to the trumpets and the chaetotaxy of the abdomen, especially of the last three abdominal segments.
