The number of known species is increased to 240, partly from descrip- 
tions furnished by Hagen in MS. Descriptions of 20 species previously 
characterized from one sex only are completed ; notes oh additional 
localities, &c., are furnished ; many new species (and some new sub- 
genera) are described ; a synopsis of the subgenus Macrogomphus appears ' 
at the commencement ; six previously described species are suppressed as 
synonyms ; a new arrangement of the divisions including the Legions 
Petalura, Chlorogomphus, and Cor duleg aster, is proposed ; Thecagaster is 
suppressed as identical with Cor duleg aster', and the subgenus Allopetalia 
is transferred to the ./Eschnina. The synonymic changes are as follows,
