294 THE ENTOMOLOGIST. 



colourless with a membranal black spot encircled by pale salmon, 

 will at once distinguish it from any of its allies. 



Tetigonia albida (Walker). 



Peradeniya, January, 1900 (E. E. Green). Reg. No. 102. 

 " Makes itself a great nuisance, swarming round lamps in the 

 rooms at night " (E. E. Green in litt. 5 (iii.), 1900. 



This pretty little species, which has been kindly identified by 

 my friend Dr. Melichar, is widely distributed, having been 

 recorded previously from North Australia, the Philippines, 

 " British India," Madagascar, Senegambia, Kaffraria, and Cape 

 of Good Hope. It is figured by Signoret, 1853, Ann. Soc. Ent. 

 France (3) i. pi. 21, f. 3. 



Tetigonia Kalidasa, sp. n. 



Belongs to subgenus Diedrocephala, Spinola. Head sub- 

 acutely triangular, vertex slightly concave, basal half very nar- 

 rowly sulcate. Pale green, an angularly arched fascia on the 

 vertex, two concentric roundly arched fasciae on the pronotum, 

 each of which is continued on to the clavus, meeting the claval 

 suture ; two fairly straight fasciae on the corium (sometimes a 

 little irregular), bright scarlet (in one specimen orange-yellow). 

 Membrane sometimes infuscate. Ventral surface pale yellowish 

 grefen. Length 4|-5^ mill. Pundaluoya (April, 1898, E. E. 

 Green) . 



This handsome little scarlet-and-green species is interesting 

 as belonging to the subgenus Diedrocephala, which is mainly (if 

 not even entirely) American. 



Thomsoniella Kirschbaumii (Stal), Sign., was omitted by 

 Kirby in his Catalogue. It is figured in Ann. Soc. Ent. France 

 (5) lb, pi. 1, fig. 44 (1880). 



IGypona striata, Kirby, 1891, J. L. S. xxiv. p. 171, and fG. 

 PRASiNA, Walker, 1858, List. Hom. Suppl. p. 258, do not conform 

 to the genus Gypona, Germ., as restricted by recent authors. 

 They are closely allied to Titia, Stal, but will probably require a 

 new genus. Both specific names are preoccupied by Burmeister 

 (Genera Insect, pi. 16), and as, according to the now generally 

 accepted rule, " once a synonym, always a synonym," they are 

 now invalid for any genus, I propose Kirbyi and Walkeri, nom. 

 nov., respectively. As Kirby surmises, {I. c. p. 171), fresh 

 examples of Kirbyi (striata) are grass-green in colour. 



Fam. FuLGOEiDiE. 

 tEuRYBRACHYS WESTWooDii, Kirby, I.e. 146, is a Messena, Stal. 



Melicharia, gen. nov. 

 Belongs to subfamily Poekillopterinae [ = Flatidae + Rica- 

 niidae auctt.J , and is very closely allied to Flata, Fabr. and
