Basal suture of front distinct and entire, centrally at least, ap- 

 proaching more or less closely the anterior margin of vertex; 

 when subobsolete above, its position always marked by a fold or 

 carina ; in the latter case, the remaining portion of frontal suture 

 is always directed toward the base of front and not toward ocellus ; 

 anterior border of vertex usually marked by a sharp margin or 



d\ Anterior border of vertex sharply laminately expanded, distinctly 

 overhanging upper part of front; antennae situated far mesad 

 of eyes; ocelli, when distinguishable, lying between extended 

 margin of vertex and basal margin of front in a transversely 

 triangular (rarely linear) ocellar area and very remote from 



e\ Pronotum extended between and cephalad of eyes; vertex very 

 short, transverse, and deeply concave. 

 f 1 . Tegmina normally veined; genae narrower than front; front 

 strongly excavate, with high raised margins; clypeus little 

 exserted; ocellar area very broad; hind tibia? with very 

 few small spines and hairs on apical half; sculpture char- 

 acterized by a deep thimble pitting Paropiidae. 



f. Tegmina with numerous supernumerary veins; genae wider 

 than front; front convex; clypeus long exserted; ocellar 

 area narrow, bounded beneath by a shallow fold; hind 

 tibiae with stout spinose teeth, few in number but dis- 

 tributed along entire length; sculpture characterized by 



coarse striations and wrinkles Stenocotidae. 



e*. Pronotum not abnormally extended between eyes; vertex not 

 very short and long transverse, the width not more than twice 

 length; ocelli a little nearer to eyes than to median line or 



f. Genae longer than broad, flat or concave, outwardly emargin- 

 ate, normally bordering the lorae to the clypeus; scrobea 

 very shallow and lacking strong supra-antennal ledges (as 

 in Stenocotidae) ; pronotum with very short lateral margins, 



converging anteriorly, ocelli distinct...- Koebeliida. 



f. Genae broader than long, strongly convex, not passing lorae 

 (at level of face), their apical margins roundly curved 

 inward to meet the front above the lorae, leaving outer 

 margin of latter fully exposed in facial view; scrobes very 

 deep, under strongly overhanging and curved supra-anten- 

 nal ledges; pronotum with very long lateral margins, 



usually converging posteriorly.... _ Ulopidae. 



Anterior border of vertex sharply marked (head may be lami- 

 nately extended between eyes) but never with this margin 

 extended beyond and overhanging upper part of front; usually 

 with clearly marked subtriangular ocellar areas at the sides 

 between vertex and front; these areas are commonly occupied 

 by the ocelli, though the latter may occur near by on upper 

 surface of crown, then usually on or outside the carinate or 

 raised lateral margin of vertex; antennae situated close to in- 

 terior line of eyes.
