PLATE XXI. 
THE following notes and descriptions relating to Orthoptera 
are based on the collection of 7Z'etriginx contained in the 
Hope Department of Zoology, University Museum, Oxford, 
England. The writer is indebted to Mr. R. Shelford, who 
generously supplied for determination the present collec- 
tion. Besides this material, the writer has drawn upon 
some examples of these insects in his own collection, which 
have not hitherto been recorded. 
This article forms a sequel to various published contri- 
butions by the writer bearing on the Z'etrigine, the last 
of which appeared in “ Genera Insectorum.”*
