Excerpt from Sarcophagidae of New England: Males of the Genera Ravinia and Boettcheria
Much of the recent work in Europe has been based on genitalia as the principal means of identification. Dr. Bottcher's paper 1 on Sarcophaga is especially deserving of commendation in this regard, and has been of great assistance in preparing this paper. The writer fully recognizes the great importance of these characters and figures are presented for each species, though in most cases their use is not necessary after one has familiarized himself with the external char acters of the group. It is doubtful if our species present the difficulties attendant upon the identification of European material, especially of those species with black genital segments. An undescribed Ameri can species of Sarcophaga and the European S. Uliginosa Kramer are the only two species which cannot be separated on external characters, but the examination of the genitalia is highly advisable when speci mens are in any way not typical.
It has been impossible to examine the types of all the species de scribed by American writers, but those not seen either do not occur in New England or there is no question as to their identity. Whenever possible the location of types, cotypes, etc., has been given with the descriptions of the individual species.
The possibility that some of the species described as new may have previously been named by Walker or others is fully recognized, but their descriptions are inadequate and it has been impossible to see the types.
