70 Mr. W. L. Distant on Homoptera. 



foveate, narrowed in front of eyes and subconically rounded 

 at apex; face elongate, subglobose, broadly longitudinally 

 flattened on disk, the lateral areas finely transversely striate, 

 near base shortly, distinctly, foveately depressed; pronotuni 

 scarcely longer than vertex, closely transversely striate, the 

 lateral margins nearly straight, somewhat obscurely trans- 

 versely impressed behind eyes ; scutellum slightly gibbous at 

 base, broadly, strongly, transversely depressed near middle. 



Long., inch tegm., ? 13 mm.

Aulacizes alalia, sp. n. 



Vertex, pronotuni, 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; tegmina 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. (Emilia.

Signoret having placed a number of distinct genera under 

 Tettigonia was thus led to treat as preoccupied many specific 

 names. The A. maculata, ^'alk., is not preoccupied in 

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

 refers belongs to the genus Acrocampsa, Stal, and = A.
