Genus RHOTIDUS. 



Rhotidus Walk., Journ. Ent., I, p. 318 (1862). 

 Type, R. cuneatus Walk. 



17. — Rhotidus aeqaalis sp. n. — Ç. liody above and abdomen 

 beneath umber-brown; head beneath, sternum, legs and segmentai 

 margins ochraceous; tegmina semi-opaque, the veins ochraceous 

 spotted with greyish-white; wings hyaline with the veins fuscous; 

 vertex of head about half the length of pronoluni, obscurely cen- 

 trally ridged, the latéral margins a little sinuate, the apex subco- 

 nical, the surface irregularly linearly marked with castaneous; 

 pronotum transversely striate, much irrorated with ochraceous, 

 and with a central dark impressed longitudinal line; scutellum 

 with angulate impression before apex, head strongly foveate at 

 insertion of antennœ; bases of spines to posterior tibia3 black. 



Long. excl. tegm. $, 12 to 14 mill. Exp. tegm. 23 mill. 



Hab. : Queensland (F. -P. Dodd — Brit. Mus.). 



There are seven spécimens of this species in the British Muséum 

 ail belonging to the female sex. The proportion of the head to the 

 pronotum, half its length, will separate it from ay of tlie species 

 described by Stâl. 



In the Rep. Esp. Stat. Haw. Plant. Assoc, Pt. IX, pp. 366-68, 

 T. XXIV and XXXI (1906), Kirkaldy bas described and parti y 

 figured seven other Australian species under this genus. From 

 the outline-figures given of the head none of then however appear 

 to belong to Rhotidus, and they apparently represent more than one 

 genus. Kirkaldy's indications of bis new species are unfortunately 

 to short to be of practical value.
