mesonotum, interior area of cruciform elevation, and posterior 

 ridges of metatotum ochraceously pilose. Tympanal coverings 

 very large and testaceously opaque, abdomen much shorter 

 than expanse of tympanal coverings, above a little more than 

 half their expanse, below about two-thirds. Apical segment 

 above testaceously tomentose. Long 42 mm., exp. teg., 128 mm. 

 Hab. — North Queensland. 



Allied to Thopha sessiliba, Dist. by pedunculate eyes, differ- 

 ing by shorter and broader abdomen, more concave posterior 

 margin of metasternum, and black head and thorax. 



There are two specimens in Coll. H.A., which I take to be- 

 long to this species.
