132 MH. W. L. DISTANT ON UNDESCRIBKD CICADID.E. [Jan. 17, 



the head, including eyes, is considerably narrower than base of pro- 

 notum ; anterior femora armed with three strong spines. 



Long. 16 millim. ; exp. tegm. 45 millim. 



Hab. Australia, Sydney. (Coll. Dist.) 



This species was identified by Walker (List Horn. i. p. 1/2. 117, 

 1850) as the Cicada melunopijgia. Germ., and thus stands in the 

 collection of the British INIuseum. Germar's species, however, 

 belongs to the genus Tihicen, and as such has been fully described 

 by Stfil (Ann. Soc. Ent. Fr. ser. 4, vol. 1, p. 618. 2, 1861.) 



Melampsalta leichardti, u. sp. (Plate VIL figs. 5, ba, 56.) 



$ . Body above ochraceous. Head with the frontal anterior 

 margin, a spot on anterior lateral angles of vertex, an oblique fascia 

 behind eyes, two small linear spots between ocelli and eyes, a trans- 

 verse spot on anterior margin of vertex, and antennae black. Pro- 

 notum with two central linear black lines, not extending to posterior 

 margin, and widened and angulated near anterior margin, oblique 

 strise, and inner border of posterior margin (on centre of which 

 is a round spot) black. Mesonotum with two short contiguous cen- 

 tral obconical spots, on each side of which is a more elongate and 

 broken one, and two small rounded spots in front of basal cruciform 

 elevation, black. Abdomen with a series of dorsal transverse black 

 fasciae, decreasing in width towards apex. Anal appendage flith a 

 black line on each side. Body beneath ochraceous ; base and 

 lateral margins of face, apex of rostrum, and ovipositor black. Legs 

 ochraceous ; femora streaked with fuscous ; anterior tibiae black, 

 annulated with ochraceous near base. Tegmina and wings pale hya- 

 line ; tegmina with the costal membrane and area and veins enclosing 

 basal ulnar area pale ochraceous, remaining venation fuscous. 



Head, including eyes, equal in width to pronotum : rostrum reach- 

 ing intermediate coxae ; face somewhat compressed, centrally and 

 longitudinally broadly sulcated for half its length, and transversely 

 striate. 

 • Long. 10 millim. ; exp. tegm. 25 millim. 



Hab. Australia, Peak Downs. 



This small but distinct species is allied to M. sericevitta, Walk. ; 

 and I am indebted to Mr. Pascoe for an opportunity of comparing 

 the same. The figure here given is considerably enlarged. 



Cystosoma schmeltzi, n. sp. (Plate VIL figs. 11, llrt, 116.) 



Closely allied to the only other known species of the genus, 

 C. saundersii, from which it differs in being only one third the size, 

 and principally in the very different venation of the tegmina, the 

 reticulations of which are faithfully portrayed in the figure, and 

 cannot be adequately described, but are different in pattern and less 

 extended in area than in the other species. The abdomen is much 

 smaller and less inflated ; the opercula are obscurely sinuated on 

 their lateral and posterior margins. 



Long. 25 millim. ; exp. tegm. 62 millim. 



Hab. Australia, Gayndah. (Mus. Godeffroy.)
