While M. australis, mihi, resembles the European species M. 

 Websteri, and M. tenuipes nearly approaches M. anomalies, the 

 present species finds its nearest ally in the commonest English 

 species — IT. gryllotalpa. 



Sub-family COEOPHIIDES. 

 Genus Colomastix, Grube. 



Colomastix Brazieri, sp. nov. (PI. XXII. , fig. 4.)
