This species is very variable in colour, from leaf-green, with one or two spots only 

 on the elytra, to pale testaceous and fuscous, with infinitely various brown spots, ocellae, 

 maculae, or tessellations, imitating shrivelled or dead leaves. — Signor Griffini has 

 described as a subspecies a variety of the colour of a dead leaf, much punctate and 

 variegated with testaceous, and having the lateral ridges of the pronotum somewhat 

 obtuse.

In this genus the tympanum of the males is generally well formed in the left elytron. 

 The two axillary veins (vena plicata, Brunn.) are much elevated, forming together an 

 acute angle. The two post-axillary veins, also prominent, do not unite together in an 

 acute angle, but are longitudinal. The post-axillary area is closed posteriorly by a 

 transverse or oblique vein, so that this area instead of being triangular is more elongate- 

 trapezoidal (sometimes opened and reticulated posteriorly, or variable) ; it is often 

 divided by a transverse oblique vein. The tympanum of the right elytron is more or 

 less coriaceous. 



Synopsis specierum. 



a. Verticis rostrum apice compressum, attenuatum vel anguste parallelum, subtus cum fastigio 

 frontis acuminatim contiguum. 

 b. Frons utrinque longitudinaliter impressa, canaliculata, itaque utrinque subcarinata. Statura

 c. Femora postica longitudinem dimidiam elytrorum parum superantia. Femora intermedia 

 subtus rarissime spinulosa. Elytra densissime reticulata, margine suturali arcuato. 

 Cerci J valde incrassati, ehelati, spina armati. — [1. angustifolia, Sss.] 



* Species hujus generis sunt numerosse et difficillimse. Multo facilius inter se mares quam feminse distin- 

 guuntur : itaque feniina quteque, si dubia sit species, mari suo de visu conferatur, eoque modo et auxilio 

 judicetur.
