The remarkable proximal antennal joints, pronotum, callosities 

 of the dorsum of the male abdomen, caudal femora with margins 

 unarmed and supplied distad with two and two very small spurs, 

 cerci and subgenital plate in both sexes, constitute only in part the 

 distinctive characters of this extraordinary and, though scarce, widely 

 distributed species. 



On the Atlantic coast it is known from as far north as Portland, 

 Connecticut, the above records being the first for the regions at present 

 under consideration. The species is extremely retiring, living only 

 in the densest tangles of heavy forest undergrowth, where solitary 

 examples can be found only after long-continued and vigorous 

 beating. 



The Genera of the Group Anaxiphites. 



In 1873, 165 Brunner erected the genus Cyrtoxipha, but failed to 

 designate by name any species; the following year Saussure used the 

 name and placed in the genus five species, 166 one of which, gundlachi, 

 Kirby 167 has selected as genotype. The characters upon which 

 Saussure separated the genera Cyrtoxipha and Anaxipha 168 have been 

 proven invalid, 169 but we find that two species of the former, gundlachi 

 and columbiana, possess characters of generic value to separate them 

 from the other species which have been assigned to these genera. 

 We are consequently obliged to restrict the genus Cyrtoxipha to these 

 two species and to place all the other American forms, hitherto 

 included in this genus, in the genus Anaxipha. This latter genus 

 is as a result found to be very large, the species of which may be 

 divided into several well-marked groups, none of which, however, we 

 feel to be sufficiently differentiated to warrant at present the erection 

 of other genera or subgenera. The type of this genus is pulicaria 

 Burmeister as designated by Kirby, 170 who, however, is in error in 

 synonymizing cxigua and pulicaria. The former is a very distinct
