Bruner: South American Crickets. 395 



the metatarsus above spined on both sides, internally three or four, 

 externally seven or eight spines, the upper internal spur shorter than 

 the median. Cerci very long, slender, and hirsute; the ovipositor 

 moderately robust, with its apex acute. Entire body sericeous, also 

 to a limited extent hirsute. 



Length of body, cT', 13 mm., 9 , 16 mm.; of pronotum, cf , 3 mm., 

 9, 3.5 mm.; width, cT', 5 mm., 9, 6 mm.; of hind femora, cf, 15 

 mm., 9 , 17 mm.; of ovipositor, 9 mm. 



Habitat.- — Male and female. Blue Hills, Nassau, Bahama Islands, 

 January, 1909. The types and three additional males are at hand. 

 They are deposited in the Carnegie Museum. All of these insects 

 seem to be somewhat immature and may represent the last nymphal 

 instar. 



This insect resembles the Amphiacusta annulipes Serville in its 

 general appearance. 



Family (ECANTHID.E. 



This family is made up of slender-bodied, herb-dwelling crickets, 

 which are usually recognized under the name of "tree-crickets." 

 Only two genera have been credited thus far to the American hemis- 

 phere. One of these, CEcanthns, is cosmopolitan, and is represented 

 by two dozen or more species. The other, Neoxabea, is only known 

 to occur in America. These two genera may be separated as follows: 



Synopsis of the South American Genera of GEcanthid^. 



A. Hind tibiae armed on their margins with weak spines and fine serrations be- 

 tween the spines. Basal joint of the antennae smooth or at most armed 

 below with a very blunt tubercle. Hind wings usually but little, if any, 

 longer than the front pair. Anal cerci rather long and slender, not sinuate. 



Qicanthus Serville. 



A A. Hind tiVjiae unarmed even with fine serration. Antennae with the basal joint 



provided at apex with a tooth-like tubercle. Hind wings nearly twice the 



length of the front pair. Anal cerci short, robust, sinuose. . . Neoxabea Kirby. 



Genus CECANTHUS Serville. 



CEcanthus Serville, Ann. Sci. Nat., XXII (1831), p. 134; Ins. Orth. (1839), p. 358; 

 BuRMEiSTER, Handb. Ent. II (1838), p. 731; Saussure, Miss. Mex., Orth. 

 (1874), p. 456; Biol. Cent.-Amer., Orth. I (1897), p. 252 and numerous recent 

 writers. 



The present genus is represented by quite a number of apparently 

 distinct species in the two Americas, some of which no doubt occur 

 in portions of both.
