A very pale, finely jiunctured species, easily recognisable from- 

 the others. 



N.B. — The genus Kalkadooua. Dist., fi-om Central Australia, 

 which Distant placed among the true Pentatominae, belongs to the 

 division Platycoriaria of the subfamily Halyinae. It has the typical 

 ventral stridulatory vittae of that group and is closely related to- 

 Oncocoris, Mayr. I saw the type of Kalkadooua centrimaculata,. 

 Dist., in the British Museum.
