Numerous species of bees, commonly referred to Panurginus, must, as has been shown by Crawford, be referred to Pseudopanurgus. This is brought out, not only by venation, but also by characters of the genitalia and sternites. It is possible that these insects are to be separated subgenerically from the coarsely punctate, typical, Pseudopanurgus, but their relationship is not with Panurginus. The South American species which I have seen are also Pseudopanurgus.
