Genus Gryllodes Saussure. 



Gryllodes Saussure, Miss. Mex., Orth. (1874), P- 409; Mem. Soc. Geneve, XXV

As indicated in the Synopsis of Genera of South American Achetidae, 

 the representatives of the genus Gryllodes differ from those of other 

 genera chiefly in the absence of an auditory opening on the inner 

 margin of the front tibiae. Most of the species also have greatly 

 abbreviated tegmina and wings, especially in the females. They are 

 rather solitary in habit and live both in shallow burrows or beneath 

 stones, chips, pieces of bark, sticks, etc., preferring open, moderately 

 dry, or well drained slopes to flat, damp localities. Ten or a dozen 

 species have been recorded from the region embraced in the present 

 paper. Representatives of but four of these are at hand.

Habitat. — A pair of this species are before me, which were taken at 

 Los Indios, Isle of Pines (G. Link, collector). It has also been 

 recorded from most of the other West Indian islands, a number of 

 Mexican, Central and South American localities, the Hawaiian Islands, 

 Australia, and some of the East Indian islands as well. It is evidently 

 a species of the sea coast which has been spread by means of commerce 

 and drifting vegetation. 



45. Gryllodes parvipennis Saussure. 



Gryllodes parvipennis Saussure, Miss. Mex., Orth. (1874), P- 419; Mem. Soc. Geneve, 

 XXV (1877), P- 216; KiRBY, Syn. Cat. Orth., II (1906), p. 43. 



Habitat. — Two female specimens are referred here. One comes 

 from Santarem, Brazil (H. H. Smith), the other bears no locality- 

 label, but is dated July. It was probably taken by the same collector 

 and at the same place. 



46. Gryllodes macropterus sp. nov. 



About the same in size and general color as G. laplatce Saussure, but 

 with fully developed tegmina and excessively elongated wings and
