The keeleri extreme with the slender elongate accessory lobe is on the other hand replaced by one with the accessory lobe almost absent, represented in fact by an angulation, while the other specimens when arranged according to their cereal character form a complete transition from one to the other. On examining the original references of keeleri and deletor it is evident that the claim made by Scudder' that keeleri is smaller than deletor is refuted by the measurements originally given from typical material. Thomas gives the measurements of keeleri, a female, as follows: Length of body 1.12 inches (28.4 mm.), length of tegmen.88 (22.3 mm.), length of caudal femur.70 (17.7 mm.); while Scudder gives the following for deletor: Length of body, male 23.5 mm., female 30.5; length of tegmen, male 21, female 22; length of caudal femur, male 14.5, female 16. It would appear from the records and evidence of material that this species is small toward the northern limit of its range (at least on the Atlantic coast) in North Carolina, from which region it ranges along the coastal plain and Gulf region to Texas and up the Mississippi to Missouri, reaching in southern Florida its maximum of size. The type of keeleri was from Florida and those of deletor from Texas, the measurements of the original specimens of both species differing little, being very much the same as found in the material studied in this connection. On the other hand south Florida (Miami) specimens are uniformly larger,10 an average pair measuring as fol...
