NO. II NEOTROPICAL DICTYOPHARIDAE FENNAH 5 



NEOMIASA, new genus 



Vertex in profile strongly convex, longer than broad (2.6: i), 

 cephalic process about 2.2 times as long as eye. Eye viewed from 

 above 1.5 times width of vertex. Frons longer than broad (1.7: i), 

 lateral margins straight, diverging distally, abruptly incurved just 

 before apex. Width across frontoclypeal suture about three times 

 width across base ; clypeus almost as large as frons, lateral margins 

 converging distally ; cephalic process in same plane as frons. Prono- 

 tum anteriorly convex, posteriorly broadly emarginate, disc devoid 

 of carinae, in form of a rounded-tumid elevation ; mesonotum ob- 

 soletely carinate or ecarinate. Protibiae slender and elongate, post- 

 tibiae 4-spined. 



Tegmina semicircularly rounded apically, M forked once in corium, 

 stigma I- to 2-celled, 2 or 3 rows of transverse veins, about 19 areoles 

 along apical margin. 



Egg ellipsoidal, a short filiform process at one pole. 



Genotype. — Dictyophara telijera Walker. 



This genus differs from Paramisia Melichar in M arising from R 

 at base, vertex in profile more strongly convex, pronotum and mesono- 

 tum relatively much broader. 



NEOMIASA TELIFERA (Walker) 

 Plate 2, figures 27-31 

 Dictyophara telifera Walker, 1858, List Horn. Suppl., p. 64. 



The figures are of Walker's type. It will be seen that it differs 

 abundantly from Toropa ferrijera (Walker) with which it has been 

 synonymized by Melichar. 



Genus HYALODICTYON Fennah

 P- 37-) 



The identification of the species ascribed to this genus cannot be 

 undertaken with any confidence from existing literature. The species 

 differ in the shape of the cephalic process and to some extent in size. 

 It is probable that when adequate dissections have been made a classi- 

 fication will also be possible on genital characters. 



The main source of confusion has been the assumption by older 

 workers, with the notable exception of Walker, that the species of 

 Hyalodictyon (considered as belonging to Dictyophara Germar) were
