5. T. RUGOSA, nov. sp. 



Closely allied to T. cucullata, agreeing with it in general 

 form and size, shape and length of the pronotum, and 

 length of the wings. The front border of the vertex is as 

 in T. cncul/ala, but it is broader, and the eyes are scarcely 

 as prominent. The whole surface of the pronotum, in- 

 stead of being delicately granulated as in T. cucul/ata, 

 with the medial and marginal carinae faint, has these cari- 

 nfc quite prominent, and the whole surface rugose, deeply 

 scarred and pitted, with irregular granulated depressions ; 

 the wing-covers are punctured as in T. granulata.

TKTTIGIDEA, Nov. gen. {Ti.TTL'c, i6ea.) 



This genus when compared with Tettix will be found to 

 differ in having a more robust and clumsy form, a larger 

 head, more swollen upon the top, and less sloping down 

 the front, the medial ridge in front more prominent, the 

 antennae consisting of twenty-two joints, which are cylin- 

 drical and not llattened ; in the joints of the maxillary 

 palpi, which here have the fourth joint much larger at the 

 apex than at the base, somewhat swollen, with a sharp 

 medial external ridge, and the fifth much swollen, flattened, 

 with a faint similar ridge, and slightly docked at the tip; 

 as in Tettix and Balruchidea the first joint is longer than 

 broad, cylindrical, the second slightly shorter than broad, 

 cylindrical, both together equalling the third, which is of 

 the same length as the fourth or lifth, and cylindrical; the 

 lower anterior angle of the sides of pronotum, which is
