form and cannot be considered in the fixation of the type of the 

 genus Anaxipha as it was not one of the originally included species. 

 The genus Falcicula 17 * is monotypic and shows close relationship 

 to Anaxipha, hut it possesses very distinctive characters in the 

 complete absence of auditory foramina on the cephalic tibia 1 and in 

 the structure of the male tegmina. The ovipositor is similar to that 

 of certain species of Anaxipha and has the margins minutely serrulate 

 distad. This feature can scarcely be seen with a hand lens and was 

 missed in the original description. 



CYRTOXIPHA Saussure. 



Genotype: Cyrtoxipha gundlachi Saussure. 



Head longitudinal, dorsal surface from behind eyes to dorsal 

 apex of inter-antennal protuberance strongly flattened and but 

 little declivent. Eyes longitudinal, much longer than deep, with 

 dorsal margin not raised above plane of flattened portion, more 

 prominent distad than proximad. Last joint of maxillary palpi 

 not as long as penultimate joint, expanding very strongly distad 

 from base with distal truncation transverse, when flattened out 

 nearly forming an equilateral triangle. Cephalic tibiae with auditory 

 foramen open en both faces. (In the two species known, the color 

 is immaculate and delicate, pale green, but this fades almost inva- 

 riably in drying to a pale brown, which is the same as the general 

 coloration in a number of species of Anaxipha. The spines of the 

 dorsal margins of the caudal tibiae are in these species extremely 

 delicate and little longer than the spaces intervening between their 

 bases. A wingless condition apparently does not occur, the wing 

 length, however, is never more than one and one-half times the teg- 

 minal length.) 



ANAXIPHA Saussure. 



Genotype: Anaxipha [Gryllus] pulicaria (Burmeister). 



Head vertical, dorsal surface not strongly flattened, strongly 

 declivent from occiput to inter-antennal protuberance. Eyes 

 vertical, much deeper than long, evenly protuberant. Last joint of 

 maxillary palpi elongate, longer than penultimate joint, distal 

 truncation transverse or oblique. Cephalic tibiae with auditory 

 foramen open on both faces in winged individuals, in wingless 

 examples normally present, but rarely open, on outer face only, 

 as in winged material. (Distinctive color patterns are developed
