This species differs from Thopha saccata, A. & 8., the only 
other described species of the genus, by the much more 
strongly sessile eyes, a character alone which will instantly 
separate the species. Besides this structural feature, the 
colour is much paler, the body almost glabrous above, and 
not pilose as in 7. saccatu ; the head, sternum, and opercula 
beneath ochraceous and not very dark casta neous, and the 
abdomen is narrower and more attenuated.

Graptotettix thoracica, sp. n. 
Head, pronotum, and mesonotum bright pale ochraceous, 
abdomen pale sanguineous. Hyes fuscous. Pronotum with 
the posterior, lateral, and anterior (as far as behind eyes only) 
margins castaneous, ‘and with two jet-black central, discal,

obconical fasciw, the central pair smallest. Abdomen above 
ochraceous near base. Body beneath and legs sanguineous ; 
head beneath, anterior coxe, and lateral margins of sternum 
ochraceous; spots on coxe black. (In the specimen 
described the apex of one posterior femur and its tibia is 
almost black, the other posterior leg is uniformly sanguineous.) 
Tegmina and wings pale hyaline, more or less completely 
tinged with castaneous (in the specimen described more so on 
one tegmina and wing than on the other), the venation 
ochraceous or castaneous.
