CRICKETS — CHOPARD 257 



serrulated; superoexternal and iiiferoexternal apical spurs very short, 

 median twice as long; inferointernal spui- very small, much shorter 

 than the external, median and superior of the same length, scarcely 

 reaching the middle of the metatarsus, which is very long. 



Elytra extending to the apex of the 6th abdominal tergite, dark 

 brown, finely pubescent, with yellowish veins; anal field small; archet 

 wdth a much-rounded angle; mirror large but somewhat confused, 

 subtriangular, filled with a rather regular reticulation; chords irregular, 

 very distant, the 2d incomplete; five obhque veins, parallel to one 

 another; apical field almost null; lateral field small, blackish, with 

 inferior margin very obhque, presenting three regular veins. No wings. 



Length of body 10.0 mm.; pronotum 2.1 mm.; width of pronotum 

 3.0 mm.; posterior femiu- 10.5 mm.; elytra 5.0 mm. 



Remarks: This species is quite distinct by the reticulation which 

 almost fills the mu-ror; this character does not fit perfectly either with 

 Ada or with Aclodes and the knowledge of other species will probably 

 lead to the reunion of these two genera.
