band. Length of body 1 inch 1 line ; expanse of tegmina 2 inches 

 4 lines. 



St. Vincent, Cape-Verds, 24th October, 1878 ; from sandy 

 patches. 



I found a second example of this species amongst the hetero- 

 geneous crowd of specimens placed by Walker under (Edipoda Jlava 

 of Linnaeus.

Dull, densely punctured ; head obtusely subconical, convex behind, 

 with marginal and dorsal longitudinal carinae, twice as long before 

 as behind the eyes, which are prominent ; thorax octagonal, fully 

 twice as broad as long, deeply excavated in front to receive the head ;

 large, half as long again as broad, obtusely triangular ; legs smooth

 dorsal margin of the pronotum nearly parallel to the anterior margin 

 of the closed tegmina ; the head vertical, almost in a line with the 

 anterior margin of the pronotum, which projects slightly in front
