On page 331 (of my former bulletin) I remarked that several 

 species had been confused and indeed, if all the forms before me 

 are one species only, it is very variable. Usually the tegmina 

 are immaculate in che female, and with a large blackish blotch 

 on the corium in the male ; sometimes however the tegmina 

 are immaculate in the male, there being gradations between. 

 The genital segments are pale in the female, black in the male ; 

 they are however, partly pale in the immaculate males. There 

 is usually a transverse, entire, black line between the ocelli; 

 sometimes this is absent, as in 2 Sinhalese females in my own 

 collection, but it is always present in the long Australian series 

 before me. The frons varies from almost entirely piceous 10 

 almost entirely testaceous. The vertex is usually obtusely 

 roimded, it is sometimes however, distinctly angulate. 



Sonicfc gen. nov. 



Probably nearest to Platymvfopiits, but the head is not so 

 elongate, the tempora much narrower, the clypeus wider, the 

 lateral margins of pronotum obsolescent and the venation dif- 

 ferent. 



Vertex produced in front of the eyes, apically obtuse-angled. 

 but not quite so long as the maximum width, disk somewhat 

 depressed. x-\ngulate in profile, the ocelli (which are large but 

 flat and probably not functional) close to the eyes on the sharp 

 margin itself. Frons broad, slightly narrowing apically, lateral 

 margins feebly rounded, tempora almost obsolete. Genae 

 sinuate, lora remote from their apical margin. Clypeus broad, 

 narrower than the apex of the frons. Pronotum a little shorter 

 than the vertex, finely striate transversely, acute-angled lateral- 

 ly. Scutellum wider' than long. Claval suture longer than the 

 mebrane, the latter with an appendix. 



I. apollonos, sp. nov. 



Brownish-olivaceous; anterior margin of vertex, an upright 

 cross on the same, the lower limb dividing into 2 almost con- 

 tiguous limbs, 4 longitudinal lines (a submedian and a sub-
