AMERICAN ORTHOPTERA. 31 



Allied to E. pictipennis Saussure and Pictet,* but possessing 

 many very distinctive characters. The median and discoidal veins 

 of the tegmina are centrally almost contiguous; the anterior border 

 of the pronotum is without a thickened margin ; the basal section of 

 the subgenital plate is as broad as long, with the carina basally 

 indistinct, and the styles are heavier. 



Size large; general build very slender; head, limbs and antenna- pilose. Head 

 broad, facial region very much flattened ; eyes subglobose, considerably exserted ; 

 antennas very long, over twice as long as the tegmina with pronotum and head. 

 Pronotum strongly tuberculate; anterior margin broadly obtuse-angulate, pos- 

 terior arcuate ; lateral lobes about twice as long as high, the lower margin thick- 

 ened, tuberculate, sinuate ; posterior sulcus strongly impressed ; lateral angle on 

 the metazoua marked. Tegmina elongate, about six times as long as wide ; median 

 and discoidal veins quite distinct distally and proximally but centrally almost con- 

 tiguous, the general arrangement of transverse veins forming quadrate or rec- 

 tangular patterns. Wings very large, about reaching the apex of the tegmina. 

 Anterior and median femora slender, sulcate beneath, bearing six or seven spines 

 on the lower external margins, genicular lobes spinose; tibiae very slender, quad- 

 rate, lower margins spined as is also the case with upper internal margins of the 

 mediau pair. Posterior femora slender, bearing fourteen or fifteen large spines 

 on the external margin, the basal portion of which is unarmed ; tibia? quadrate, 

 spined on the margins. Subgenital plate basally broad, keeled, the lateral margins 

 bent upwards, the terminal portion bent sharply upwards and bearing the ''four 

 leaf clover" appendage characteristic of the genus. Styles robust, rounded and 

 not angulate, the apical portion of each suddenly constricted. 



General color uniform dull brownish yellow (specimen probably having been 

 at some time in a liquid preservative^. Wings with the disk dull grayish brown, 

 the anterior field and periphery of the general tint.

Nine specimens; four males, five females; Mexico. Coll. Acad. 

 Nat. Sci. Phila. (1). Teocelo, Vera Cruz, Mexico. Collected by 

 Otis W. Barrett (3). Jalapa, Vera Cruz, Mexico. August and 

 September. Collected by Otis W. Barrett (5).f 



In one of the males the apex of the subgenital plate is not emar- 

 ginate, as in the specimen from Orizaba, described by Saussure and 

 Pictet,| the other three having the apex broadly emarginate.
