iiae) (Plate 1, fig. 1, c) and Stenotortor (Nirvaniidae-Macroce- 

 ratogoniinse) (Plate 1, fig. 1, e), the first joint is distinctly 

 shorter than the two succeeding, the terminal crowns of spines 

 being reduced, and the first joint is supplied with numerous late- 

 ral spines. In these cases the third and second joints are in- 

 serted but little before the apex of the proximal joints, or at the 

 extreme apex as in Stenometopius. In Paropia (Paropiidaa) 

 the apical crowns of spines are entirely lacking and the second 

 joint is distinctly shorter than the third, as in Preta (Signore- 

 tiidae) (Plate 1, fig. 1, d). However, it will be impossible to 

 make generalizations as to these characters until the types of 

 all older species in these groups can be reexamined. 



Superfamily JASSOIDEA 

 Synopsis of families. 9 

 a 1 . Upper part of front strongly raised and produced, its posterior portion 

 forming a large part of superior surface of head (crown) ; the true 

 vertex confined to basal portion of crown, the ocelli thus on posterior 

 disk of crown and usually remote from eyes. 

 o 1 . Lateral sutures of front distinctly continued over the obtuse anterior 

 margin of crown to near the position of ocelli (as in the Cercopidae) ; 



antennae between and near eyes _ Tettigoniellidas. 



b\ Lateral sutures of front obsolete beyond antenna? or beyond anterior 

 border of crown. 

 c 1 . Antennae not far removed from eyes and near but never above level 

 of eyes ; lateral margins of front obsolete beyond scrobes. 

 cP. Head acute angled between crown and face; face of normal 

 proportions; lateral sutures of front entering and terminating 

 in antennal scrobes, face shallowly concave ; body long ovate. 



Gyponidae. 



0?. Head obtusely rounded between the strongly declivous crown and 



face, strongly overhanging the latter, which is deeply concave; 



lateral sutures of front passing mesad of antennae; face very 



short, far broader than long Penthimiidae. 



c 2 . Antennae situated entirely above and far removed from eyes; head 

 anteriorly transversely thin laminate. 

 d 1 . Outlined lower portion of front short and broad. 



Thaumastoscopidae. 



d\ Outlined lower portion of front long and narrow Ledridae. 



a". Upper part of front confined entirely to face, except sometimes for a 



b 1 . Vertex entirely superior, occupying nearly all or all of crown, the 

 junction with front occurring on anterior border of crown, the ocelli 

 on or near anterior border of head. 



° This synopsis, In the present abbreviated from, uses principally cephalic 

 characters. Many coordinated characters can be drawn from other parts 

 of the body, notably tegmina, wings, and legs.
