188 MR. W. L. DISTANT ON THE CICADID^. [Apr. 17, 



very large and uncovered ; and the head (including outer margins of 

 ej'es) is about equal in width to the base of the mesonotum. 



Long. 24 millira. ; exp. tegm. 85 millim. 



Hfib. (unknown). (Mus. Dresden.) 



The unspotted tegmina, apart from the structural peculiarities, 

 render this species very distinct. 



Tettigarcta crinita, n. sp. (Plate XXV. figs. 5, 5a, 56, 5c.) 



cj . Body above reddish ochraceous. Head with the front clothed 

 with very long fuscous hairs, and with a thick and long tuft of the 

 same at base of vertex (which is slightly convex), stretching across 

 the ocelli ; eyes dull obscure grey mottled with brownish. Pronotum 

 wrinkled and rugulose, the lateral angles broadly truncate and 

 slightly concave, the lateral margins rounded, reflexed and some- 

 what ampliated ; a moderately raised subovate space at anterior 

 margin which is hairy, on each side of which are two connected 

 rounded spots with fuscous margins, the outer of which are most 

 distinct. Cruciform elevation at base of mesonotum elongate, its 

 base petiolate. Abdomen with the posterior segmental margins 

 fuscous and hairy. Body beneath and legs ochraceous, thickly 

 clothed with greyish hair ; apices of tibise, apices of tarsal joints, 

 and claws castaneous. Rostrum reaching posterior coxse and with 

 its apical half pale fuscous. Face conically compressed and covered 

 with long fuscous hairs. Tegmina subargentaceous or pale talc-like, 

 the venation, costal membrane, and basal and claval areas ochra- 

 ceous ; a small fuscous spot beneath and near the end of costal mem- 

 brane, and a few small fuscous markings near base. Wings subar- 

 gentaceous or pale talc-like, the venation ochraceous, and the base 

 narrowly pale fuscous. 



Long. 32 miUim. ; exp. tegm. 80 millim. 

 Hab. Australia, sic. (Mus. Dresden.) 



This species differs from T. tomentosa, the only other described 

 species of the genus, in the non-pointed and truncate lateral angles of 

 the pronotum, the paler tegmina, and absence of the fuscous macular 

 markings on their apical halves, &c. 



The extent of this genus and its exact habitat are still interesting 

 questions. It is now nearly forty years since Adam White de- 

 scribed the genus from specimens of a single species collected 

 during Eyre's expedition of discovery in Central Australia; and the 

 only habitat given was "Australia." Now a second species is 

 found in the Dresden Museum, but also with the same loosely 

 ■worded habitat. 



DUNDUBIA RAFFLESIl, n. Sp. 



S . Head and body above ochraceous, moderately and palely 

 pilose. Eyes pale brown mottled with fuscous, ocelli bright cas- 

 taneous ; posterior and lateral margins of pronotum greenish 

 ochraceous ; mesonotum vvith two central pale and subobsolete 

 obconical spots situate at anterior margin, with an obscure pale 

 fuscous oblique streak on each side. Body beneath and legs
