6 E. T. Atkinson — Notes on Lidiati Rliyncliota. [No. 1, 



of species of the genns Phymatostetlia has been increased by two, of 

 which one comes from Ceylon and one from Assam ; both have been 

 described by Mr. Distant. The Indian Musenm possesses about ten, 

 apparently nndescribed, species which may be referred to these genera, 

 and which will form the subject of a separate paper hereafter. 



Genus COSMOSCARTA, Stal. 



Hem. Fabr. ii. p. 11 (1869) : Of vers. Kong. Yet. Aka. Forh. p. 718 (1870). 



Frons very large, very tumid, obtuse, extended on the facial side 

 almost to the eyes, devoid of any longitudinal furrow or keel. 



1. CosMOSCARTA TRICOLOR, St. Farg. and Serv. 



Cercopis tricolor, St. Fargeau and Serville, Enc. Meth. x. p. 605 (1825) : Burm. 

 Handb. Ent. ii. (i) p. 124 (1835) : Walker, J. L. S. Zool. i. p. 95 (1856) ; ihid., p. 165 

 (1857). 



Cosmoscarta tricolor, Butler, Cist. Ent. i. p. 245 (1874) : Distant, J, A. S. B. 

 xlviii (2) p. 38 (1879). 



Black, shining : head, thorax, scutellum towards the tip, hind 

 borders of the abdominal segments, the tip of the abdomen and the legs, 

 red : femora black, the four anterior red towards the tips : six red spots 

 on each tegmen at the base. A Tenasserim variety in the Indian 

 Museum differs from the type in having the subbasal fascia represented 

 by a transverse series of four sanguineous spots ; there is also a spot of 

 the same colour at the base. It is thus intermediate between G. tricolor 

 and G. hasinotata, Butler (Cist. Ent. i. p. 245), which differs also in the 

 coloration of the abdomen {Distant). Body long 22 : exp. teg. 51 

 millims. 



Reported from Borneo, Java, Singapore, and Tenasserim ; a speci- 

 men from the last locality is in the Indian Museum. 



2. CoSMOSCARTA BASINOTATA, Butter. 



Cosmoscarta hasinotata, Butler, Cist. Ent. p. 245, t. viii, £. 2, (1874) : Distant, 

 J. A. S. B. xlvii (2) p. 194 (1878). 



Form of G. tricolor : differs chiefly in having the tegmina crossed at 

 the base by a patch of six red spots (that on the clavus being more or 

 less bifid) instead of the pale testaceous band, and in the narrower and 

 interrupted red bands margining the segments on the dorsum of the 

 abdomen {Butler'). Long. 21 : exp. teg. 47 millims. 



Reported from Sarawak, Tenasserim.
