southward are features shared by a number of species, which differ- 

 ences, uncorrected with other characters, we do not feel are suf- 

 ficiently clear cut to constitute racial criteria, the two extremes in 

 this case grading gradually into one another instead of showing 

 uniformity over definite areas and intergradation over relatively 

 smaller ones. 



The previous analysis of the characters of pulcher covered the 

 supposedly diagnostic features, i.e., size, tegminal length, fastigial 

 form, frontal costa and color. A re-examination of these features 

 shows that the general size as a rule follows the usual increase in 

 size southward, but that in the series from Lake Waccamaw, Winter 

 Park, Yemassee, Jesup, Tybee Island and Sandfly we find individ- 

 uals of both sexes which are similar in this respect to New Jersey, 

 and others to southern Florida, specimens. Regarding the relative 

 length of the tegmina, we find no specimens in the present material 

 with tegmina as long as south Florida representatives, but each 

 series shows a considerable degree of individual variation in this 

 respect in both sexes. The four females from Jacksonville all 

 have the tegmina very short, not surpassing the middle of the third 

 abdominal segment, lanceolate and acute. The form of the fastigium 

 shows a general uniform broadening southward, but, like the length 

 measurement, occasional individuals of both sexes have it as narrow 

 and as much angulate as in New Jersey specimens. The sulcation 

 of the frontal costa varies greatly in degree, to a certain extent 

 geographically, but to a greater one individually. 



As we have said before, the more southern specimens exhibit color 

 patterns not observed in more northern individuals. This statement 

 holds true in the light of the present material, the extreme trilineate 

 form being suggested in but a few individuals, these from southern 

 Georgia, although blackish or largely blackish specimens are present 

 in the Wilmington, Lake Waccamaw, Yemassee, Sandfly, Homer- 

 ville, Jacksonville and Atlantic Beach series. These blackish speci- 

 mens are females and without exception they were taken on wet 

 black ground in swampy situations. 



The Texas specimens are inseparable from Georgia individuals 

 and the range of the species is considerably extended by these 

 records. In the southern States the species is found at greater 

 distances from the coast line than is the case to the northward, but 

 nowhere has the species been found above the fall line; Fayetteville, 

 North Carolina, being the farthest inland locality from which it is 

 known. The range extends from western Long Island, New York
