16 STUDIES IN AMERICAN TETTIGONIIDAE (ORTHOPTERA) 



given in the Flint edition of Harris® shows an individual with a 

 curved ovipositor {%. e. a true Orchelimum and probably 0. con- 

 cinnum). The figures in this edition were drawn under the direc- 

 tion of Agassiz, so the preface informs us, and the ovipositor 

 character of the figure is belied by the text on the same page, this 

 being a reprint of that of the original edition. It is quite evident 

 that the specimen drawn was not the one described by Harris. 

 The name gracile certainly does not properly apply to any form 

 of Orchelimum. It has been considered to represent the pale- 

 faced phase of concinnum, by a few authors, but that it has no 

 right to be so considered is very evident. 



There has been so much irregularity in the use of the name 

 agile that the records quoted under it are almost valueless in 

 mapping the distribution of the species. In the majority of 

 cases it is quite impossible to say which species the author who 

 recorded "agile" had before him, and unless the material on 

 which such records were based is definitely recognizable in the 

 the series examined by us, we have felt compelled to ignore the 

 indefinite records in our mapping work. 



The other names, the apphcation of which has given difficulty 

 in the past or has given trouble to the present authors, are best 

 discussed here. Burmeister's glaherrimum has been frequently 

 recorded, but generally the specimens proved to be long-winged 

 individuals of vulgare. We have carefully studied the very brief 

 description, have studied the movements of Zimmermann who 

 collected the specimens, eliminated the other forms occurring 

 in the teritory where he collected at that time, and there is no 

 doubt in our minds that we have properly located the form. An 

 effort to locate the original specimen has met with no success 

 other than the proof that it does not exist in the Halle collection. 

 Serville described three species of the genus when he originally 

 founded the same, i. e., cuticulare, glaucum and herbaceum. The 

 first of these undoubtedly equals Burmeister's glaherrimum, as a 

 careful analysis of the description and comparison with all the 

 known species shows. The second species, glaucum, just as 

 certaily equals agile (DeGeer) when examined in the same fashion. 

 The last name, herbaceum, has been generally placed as the same 

 as concinnum Scudder, chiefly because Serville says it has a black
