 at apex ; face elongate, subglobose, broadly lougitudinally 

 flattened on disk, the lateral areas finely transversely striate, 

 near base shortly, distinctly, foveately depressed; pronotuni 

 scarcely longer tiian vertex, closely transversely striate, the 

 lateral margins nearly straight, somewhat obscurely trans- 

 versely impressed behind eyes ; scutellum slightly gibbous at

Aulacizes alalia, sp. n. 



Vertex, pronotum, and scutellum black ; vertex with some 

 greyish linear spots between eyes and ocelli; pronotum with 

 transverse series of irregular, macular, virescent lines from 

 a little beyond base to apex ; abdomen above sanguineous, the 

 apex more or less black ; head beneath and sternum black, 

 legs and abdomen beneath sanguineous, the anal segment 

 black ; tegmiua brownish testaceous, thickly sprinkled with 

 small pale annulations, a large pale stramineous spot at 

 base ; wings hyaline, the veins piceous, the apex and outer 

 margin fuscous ; vertex elongate, longer than breadth be- 

 tween eyes, broadly foveately depressed for half its apical 

 length, a central incised longitudinal line on basal area; 

 face elongate, profoundly foveate at base, after which it is 

 centrally, broadly, longitudinally flattened, the lateral areas 

 finely transversely striate ; pronotum scarcely longer than 

 vertex, closely transversely striate ; scutellum broadly trans- 

 versely depressed a little behind middle. 



Long., excl. tegm., 10-12 mm. ; exp. tegm. 19-21 mm.

By the elongate vertex and slender form allied to the 

 preceding species, A. amilia.

Signoret having placed a number of distinct genera under 

 Tettigonia was thus led to treat as preoccupied many specific 

 names. The A. maculata, Walk., is not preoccupied in 

 Aulacizes. The Ciccus maculatus. Walk., to which Signoret 

 refers belongs to the genus Acrocampsa, Stiil, and=:/i.
