This paper presents techniques that allow careful study of terminalia, indicates the range of development of the proctiger lobes in Uranotaeniu, and considers their possible phylogenetic significance. It is hoped others will be stimulated to investigate the proctiger development of additional species of Uranotaenia and allied genera. Further study of the variation in the form of the basotergal lobes of the proctiger with speciation will, we feel certain, increase our understanding of the phylogeny within the genus and with other genera. The experiences gained from the present study indicate the need to emphasize the absolute necessity of dissecting the terminalia of Uranotaenia, for an accurate interpretation of all the structures. Whole mounts are totally inadequate and should be made only after an adequate series of dissections has been prepared. In view of the obvious value, we present a detailed discussion of techniques we have found satisfactory for the preparation and dissection of the terminalia of Uranotaenia.
