from the figures given. The head and venational characters 

 appear to indicate this position. 



Synopsis of subfamilies. 

 a\ Antennae situated at upper angle of eyes (in facial view) or above this; 

 lateral carinas of vertex more or less distinct; ocelli always visible 

 from above, on upper portion of lateral border, or on anterolateral 

 portion of crown; eyes prominent; posterior border of pronotum more 

 or less distinctly incurved. 

 b 1 . Antennae seated in deep transverse sharp-margined scrobes ; face about 

 as broad as long or broader; eyes small; vertex short half -ovate. 



Macroceratogoniinje. 

 b 2 . Antennae in shallow scrobes of ordinary type; face usually much 

 longer than broad; vertex long; eyes large; tegmina without sub- 

 apical cells, the veins of corium usually indistinguishable except by 



transmitted light Nirvaniinae. 



a 2 . Antennae situated at middle of eye margin (in facial view) ; lateral 

 carina? of vertex wanting; ocelli below anterior border of crown and 

 not visible from above; head (from above) long spatulate, but not 

 thin dorsoventrally; eyes not prominent, deep set in vertex; pronotum 

 subtruncate posteriorly; tegmina with two subapical cells. 



Steuometopiinse. 

 MACROCERATOGONIIN>E 



Synopsis of genera. 

 a 1 . Body not depressed; pronotum narrowly rounded between eyes; crown 

 narrow basally, broadly rounded apically, the margin not notched over 

 antennal scrobe; eyes set in middle of lateral margins of face (facial 

 view), large; antennal flagella longer than body; lora? very broad; 

 clypeus broadened apically; proboscis of moderate length; subcostal 

 cell of tegmina without supernumerary cross veins (Macrocerato- 



goniini) Macroceratogonia Kirkaldy. 



a 2 . Body more or less depressed; pronotum subtruncate or very broadly 



rounded between eyes; crown broad basally, obtuse angled apically, 



margin deeply notched over antennal scrobe; eyes set below middle of 



face, small; antennal flagella very short; lorae narrow; clypeus 



narrowed apically; proboscis very short; subcostal area with a number 



of supernumerary cross veins (Balbillini). 



b\ Body but slightly depressed; tegmina not strongly narrowed apically, 



the subcostal area not greatly broadened, or with strongly curved 



outer margin; tegmina membranous, venation distinct throughout. 



Balbillns Distant. 



b 2 . Body very strongly depressed; tegmina tectiform, strongly narrowed 



apically, the subcostal area expanded, and the outer margin strongly 



curved; tegmina subcoriaceous, venation obscure basally.
