ORTHOPTEROUS GROUP INSARAE 



elevated cephalad and caudad; lateral margins of dorsum of pronotum ob- 

 scure and strongly concavo-divergent in cephalic fifth, then pronounced in 

 remaining four-fifths, for half of which portion it is strongly convex but 

 weakly divergent then as decidedly convex and very strongly divergent, the 

 angles formed by these margins all broadly rounded: cephalic margin of 

 dorsum or pronotum weakly emarginate, caudal margin of same very broad- 

 ly arcuato-truncate ; lateral lobes of pronotum with length slightly greater 

 than depth (slightly deeper caudad than cephalad), the ventro-cephalic 

 angle obtusely rounded, the ventro-caudal angle broadly rounded, ventral 

 margin nearly straight, very weakly sinuate, humeral sinus indicated by a 

 very shallow, broadly rounded, obtuse angulation. Tegmina aborted, ex- 

 tending little beyond the distal extremity of the tjonpanal area, distal mar- 

 gin broadly rounded with this arcuation continued into the costal margin 

 without angulation; the wings are present as mere atrophied slips wholly 

 concealed by the tegmina. Disto-dorsal segment of abdomen produced me- 

 sad with that portion of caudal margin truncate, the segment deeply cleft 

 mesad and divided into two large evenly arcuate lobes which nearly envelop 

 the cerci; cerci short, rather strongly incurved, crassate, tapering but little 

 to the flattened apex which is toothed, this tooth directed meso-dorsad at an 

 angle; sub-genital plate very short and broad with lateral margins arcuate- 

 convergent distad, distal extremity shallowly obtuse-angulate emarginate, 

 bearing laterad blunt knobs, cephalad these knobs are continued as slightly 

 divergent rounded elevations which become obsolete about the middle of the 

 plate. Cephalic and median femora slender; these joints carinate dorso- 

 distad for a very short distance with distal margin bluntly rectangulate pro- 

 duced; genicular lobes of same produced in a broad (blunt or finely spined) 

 tooth which tooth bear^ a supplementary spine on its ventral margin ; distal 

 portion of ventro-cephalic margin of cephalic femora bearing 1 to 2 small 

 teeth. Caudal femora heavy with proximal half buUate; genicular lobes 

 broad, acute-angulate produced, with immediate apex bluntly rounded. 



In addition to the type a nymphal male bearing the same data 

 may be considered paratypic. 



Measurements (in millimeters) 



Color Notes. — Both specimens are dried alcoholics but still show 

 traces of dorsal markings. The type indicates that the fourth 

 dorsal abdominal segment was heavily marked, while in the nymph
