distinguished easily by its large pronotal elevations, its widely separated 

 posterior tibial spines, the absence of an M -shaped elevation bordering 

 the posterior margin of the crown, its foveate antennal ledges, and its 

 rather short male pygofer in relation to the length of the plates. 



Dr. James P. Kramer (in litt.) has called attention to the new com- 

 bmation and new synonym in the following check list. 



The genitalia of the lectotype of Z. haenschi Breddin are closely similar 

 to those in figure 54, with die apex of the aedeagus being closer to 

 figure 54k than to 54j.

Type-species : Tettigonia corticata Signoret. 



Length 14-22.5 mm. 



Head moderately produced, median length considerably less than 

 interocular width, apex elevated and carinate, ocelli on line between 

 anterior angles of eyes, each equidistant between adjacent eye angle 

 and median line, crown with an M -shaped elevation bordering pos- 

 terior margin, with a broad shallow median fovea, with a slight, 

 indistinct longitudinal carina laterad of each ocellus, disc with or 

 without pubescence; antennal ledges not foveate, usually not carinate 

 dorsally in lateral aspect, anterior edges declivous; clypeus with disc 

 depressed, muscle impressions distinct; face finely pubescent, clypellus 

 protuberant, keeled, contour of its lower portion at right angle to 

 profile of clypeus. 



Thorax v/ith pronotal width greater than transocular width of 

 head, lateral margins usually convergent, disc punctate, rugose, or 

 pitted, pubescent or not, posterior margin concave, with a complete 

 dorsopleural carina which is arched ventrally; scutellum transversely 

 striate on posterior half. Forewing with or without a membrane, veins 

 elevated and distinct, surface occasionally pitted, usually with four short
