Arenopsaltria, n. gen. 



I have ventured to separate out from the genus Hcnicopsaltria 

 those members having the head and thorax deeply granulated. 

 Another common difference is that the abdomen, which is broader 

 in H. eydouxii, Guer., and H. kelsalli, Dist., than the thorax, is in 

 these species, the same width. These characters are not the onl>r 

 differences. The wings of the three species fullo, Walk., nubi- 

 vena, Walk., and pygmaea, Dist., are relatively very much shorter 

 than those of the typical Henicopsaltria. And the second abdom- 

 inal segment of Henicopsaltria is much longer than that of the 

 proposed new genus. There are other and minor differences- 

 which workers in the family will notice.

I have not seen this species, and the type is not in Australia,, 

 and therefore I append Distant's description : — 



Body ochraceous brown, abdomen castaneous. Pronotum with 

 central ochraceous line; on each side of which is a narrow black 

 fascia extending from anterior margin to near middle. Meso- 

 notitm with two obscure central obconical spots on anterior mar- 

 gin, cruciform elevation ochraceous. Abdomen above with the
