34 STUDIES IN AMERICAN TETTIGONIIDAE (oRTHOPTERA) 



and from Raleigh, North Carolina, and Chestnut Hill and Tinicum, Penn-

'We have traced out the movements of Zimmermann, who 

 collected the material on which Burmeister founded the species, 

 and find that Georgetown, South Carolina, is the only locality 

 which he had visited in "South Carolina" up to the time Bur- 

 meister 's work appeared. Accordingly we have selected that 

 place as the type locality. An effort to locate the original mate- 

 rial has been unsuccessful, the only thing positive being the 

 assurance from Prof. 0. Taschenberg that it does not exist in the 

 Halle collections. 



Regarding the synonymy of cuticulare with the present species, 

 a careful study of the description of Serville's species shows con- 

 clusively that they are the same. The name cuticulare has been 

 erroneously used by Redtenbacher for a species which we are 

 here naming calcaratum. The lack of appreciation by some 

 European workers of American geography and the settlement of 

 the country is evidenced by the reference of a form described as 

 long ago as 1839, to a species found only in a region which up to 

 that time was largely the proverbial howling wilderness, trav- 

 ersed only by pioneers and strong government detachments. 



Mr. Davis has been kind enough to place in our hands an exten- 

 sive series of New Jersey, North Carohna and Florida specimens 

 of this species, those from the first mentioned state being typical 

 of his erythrocephalum. These confirm the previously expressed 

 opinion of the authors regarding the synonymy of the two forms. 

 The smaller size of the New Jersey specimens is explained when 

 a series representing localities extending from that state to Florida 

 is laid out, as the increase in size southward is in general regular, 

 with, however, the usual amount and percentage of individual 

 variation found in forms of this genus. Environment also is 

 without doubt an influencing factor in regard to size. In no
