bare, narrower in front than at the base of the wings, and bear- 

 ing distinct shoulder-tubercles. Scutellum with two spines. 

 Abdomen nearlv bare, about twice as long as broad, narrow at 

 the base and broadening posteriorly, with a rounded apex. Legs 

 long and slender, with the tarsi greatly lengthened. Wings 

 large, veins distinct and not crowded anteriorly; cubital vein 

 forked; four, posterior veins present, the fourth arising from the 

 junction of the discal cell and the second basal cell. 



This genus is proposed for a very remarkable, Victorian species, 

 which apparently mimicks one of the Hymenoptera. It may be 

 easily distinguished by the extremely long antennae, variegated 

 colouring, and greatly lengthened tarsi. It seems to come nearest 

 to the Mexican genus Compeprosopa in the subfamily Stratio- 

 myince; it bears no resemblance to any other Australian genus, 

 although, in the venation and formation of the legs, it seems to 

 show certain affinities to Geranopus.
