68 ORTHOPTEROUS GROUP INSARAE 



irregular in outline but with convexity dorsad, these bands with 

 least separating width on the third abdominal segment. The outer 

 distal portions of the cephalic and median femora and the outer 

 proximal portions of the cephalic and median tibiae are darkened, 

 approaching prout's brown in color. The original description 

 indicates that the male specimen here described is somewhat less 

 heavily marked with the darker shades than the type, the spot re- 

 ferred to there as "a large black maculation near the extremity of 

 the tegmen" is, in the specimen before us, indicated merely by a 

 narrow dark marking one millimeter in length. From the series of 

 Insara of similar coloration before us, it is evident that often th.e 

 darker markings fade considerably in drying with the exception 

 of those found on the dorsal surface of the abdomen. 



. Distribution. — The present species has been taken at Temax in 

 northern Yucatan, at Aspinwall Barrio on the Isthmus of Te- 

 huantepec and at Castillo in southern Nicaragua.

This insect differs from its close relative I. phthisica in having 

 a less attenuate structure and in the male a different disto-dorsal 

 segment of the abdomen and shorter cerci, the shaft of which latter is 

 less decidedly curved and has a noticeable inward deflection at the 

 middle. An even greater general resemblance to the species allied 

 to /. tolteca, than is found in phthisica, is in consequence shown. 

 The relationship, however, to the northern species near /. elegans 

 is quite as close as is found in phthisica.
