NO. II NEOTROPICAL DICTYOPHARIDAE FENNAH II 



siders it necessary to establish the above generic and specific 

 synonymies. 



Family TROPIDUCHIDAE 



Tribe TAMBINIINI 



Genus ROTUNOSA Distant 



Rotunosa Distant, 1906, Ann. Mag. Nat. Hist. ser. 7, vol. 18, p. 353. (Ortho- 

 type, Dictyophara indicanda Walker, 1858, List Horn. Suppl., Addenda, 

 p. 318.) 



Roesma Fennah, 1945, Proc. U. S. Nat. Mus., vol. 95, p. 481. (Orthotype, 

 R. grandis Fennah, ibid., p. 482.) 



ROTUNOSA GRANDIS (Fennah), nevsr combination 



Material of R. grandis Fennah, when compared with Walker's 

 holotype, proved to be definitely congeneric. The species are quite 

 readily separated by the proportions of the vertex. 



Tribe PARICANINI 



Genus NEOMMATISSUS Muir 



Neommatissus Muie, 1913, Proc. Hawaiian Ent. Soc, vol. 2, p. 267. (Ortho- 

 type, N. spurctis Muir, ibid.) 



As this genus has been included in a recent catalogue of Dictyo- 

 pharidae (General Catalogue of Hemiptera, fasc. IV, pt. 8, p. 71), 

 it is advisable to record that the genotype is a paricanine tropiduchid, 

 as are those of the synonymous genera Stacotoides Distant and 

 Trobolophya Melichar. The species are quite conveniently separated 

 by the venation of the tegmina. 



NEOMMATISSUS CONGRUUS (Walker), new combination 



Plate 2, figure 45 



Brixia congrua Walker, 1870, Journ. Linn. Soc. Zoo!., vol. 10, p. 110. 

 Neommatissus spnrcus Muir, 1913, Proc. Hawaiian Ent. Soc., vol. 2, p. 267. 



Material of N. spnrcus Muir bearing Muir's determination label 

 cannot be distinguished from the holotype of Brixia congrua Walker. 

 The mesonotal carinae are strongly elevated. The figure is from 

 Walker's mutilated holotype.
