This insect agrees with A. pulicaria in many respects, but is a 

 smaller, more delicate species. A distinctive color pattern is 

 developed which, when present, readily distinguishes the species. 177 

 This is strongly marked in the specimens from Atlantic Beach 

 (figured) and Punta Gorda, but very weakly indicated and only by 

 the marking of the occiput and dorsum of the pronotum in the 

 other two specimens. 



The specimens here recorded arc wingless, numerous long-winged 

 examples are present, hoAvever, in the exotic series before us. All 

 of the winged individuals have open auditory foramina on both 

 faces of the cephalic tibiae; in the wingless examples this organ is 

 missing on the inner face of these members. 



This tiny species was not previously known to exist within the 

 United States, a large series now before us shows it to be probably 

 the most abundant and widely distributed species of the genus in 

 Cuba and on the Gulf coast of Mexico.

Individuals of this minute species are distinguishable from any 

 others of the Group Anaxiphites, not only by the absence of auditory 

 foramina on the cephalic tibiae, but also the remarkable reduction 



177 Large exotic series before us show that the species develops an unusual 

 complexity of markings. Certain examples, in the Mexican series, are excep- 

 tional in having the caudal femora suffused dorsad and narrowly banded mesad 

 on the outer face with very dark brown, while rare individuals have the dorsal 

 field of the tegmina fuscous. Other specimens have no dark markings whatever 

 and can only with difficulty be separated from small individuals of A. pulicaria, 

 which species is, however, appreciably more robust.
