NOTES ON THE NORTH AMERICAN SPECIES OF ISODONTIA, PATTON, WITH DESCRIPTIONS OF A NEW SPECIES AND VARIETY
Published online by Cambridge University Press: 31 May 2012
Extract
I am hardly prepaled at present to accept Isodontia elegans, Smith, as a variety of I. apicalis, Smith. The differences between the two seem to be very constant, and their distribution appears to be somewhat different, elegans being more a southern and western form, while apicalis occurs chiefly in the central, eastern and northern States.
