98 Howard Ashton : 



following greyish-white markings : — A small spot at inner angle 

 of each tympanal covering, a broad anterior fascia (broken cen- 

 trally) to second segment, and the anterior margin of anal seg- 

 ment. Tegmina and wings talc-like, venation ochraceous, teg- 

 mina, with the following fuscous spots : — One on each longitud- 

 inal vein to third ulnar area, each side of the transverse veins at 

 apices of ulnar areas, and one at the apex of each longitudinal 

 vein to apical areas. Head, pronotum and mesonotum granulose, 

 rostrum reaching posterior coxae, tympanal coverings prominent 

 and finely transversely striate, abdomen finely pilose, opercula 

 rounded, not extending beyond the anterior margin of the first 

 abdominal segment. Tegmina only a little longer than body. 



Long. Corp. 14 mm., exp. teg. 39 mm. 



Hab.—S.W. Australia. 



Allied to H. fullo, Walk., but very much smaller. 



Arenopsaltria unicolor, n. sp. 



Body above and below concolorous, a dull yellowish-brown, 

 except for the following browner and darker markings: Vertex 

 of head between eyes, obscure linear fasciae, enclosing central 

 paler stripe on pronotum, posterior pronotal margin, and posterior 

 abdominal segmental margins ; beneath, facial sulcus, apex of 

 rostrum, and opercula. Tegmina hyaline, veins at bases of apical 

 areas, except 8th, more or less infuscated. Costa and venation 

 on basal half ochraceous, darker on apical half, basal membrane 

 yellow; wings with venation on basal half ochraceous, darker on 

 apical half. 



This species apparently lacks the white tomentum so prominent 

 in the .three other species of this genus. It may also be easily 

 distinguished by the unicolorous body, and the less heavily infus- 

 cated tegmina. 



Long, male 23 mm. ; expense of tegmina, 67 mm. 



Hab.— Perth, West Australia. Coll. by Mr. G. H. Hardy. 

 Type in Australian Museum, Sydney.
