East Indian species E. nchulosa Burnieister differs in thcform of the

 apex of the tegniina, and the broader subgenital andmon; rounded 

 supraanal plates of the male. 



M<(J('. — Size medium; form elongate-ovate. Head projectino- oon- 

 sidei-ably beyond the pronotum, the anterior margin subtruncate; 

 interspace between the eyes and that between the ocelli equal; ocelli 

 large, touching the eyes; eyes irregularly reniform, the greatest depth 

 anteriorl}'; antenna^ not quite equaling- the bod}- in letigth. Pronotum 

 heptagonal; anterior margin truncate; posterior margin obtuse angu- 

 late; postero-lateral n'largins shorter than any of th(? others; all angles 

 blunt and rounded; lateral portions of the pronotum depressed. Teg- 

 mina elongate, considerably exceeding the apex of the abdomen; costal 

 margin gently arcuate, sutural margin straight, apex very obtusely 

 rounded; basal field equal to one-third the length of the tegmina; 

 costal viens numerous and sublongitudinal in character; ulnar vein 

 with seven distinct rami; anal sulcus very slightly arcuate, anal field 

 reaching two-fifths the way to the apex of the tegmen. Supra-anal 

 plate produced, bilobate, the centrally fissure quite deep. Cerci 

 broken. Snbgenital plate produced, subtruncate. Anterior femora 

 with tive large median, one apical, and an intermediate series of minute 

 spines on the anterior margin, posterior margin with five medium- 

 sized spines, no genicular spine present; tibia? about three-fourths 

 the length of the femora; tarsi exceeding the tibia? and not equiding 

 the femora in length. Median femora with four evenly distributed 

 spines on the median and distal portions of the anterior margin, pos- 

 terior margin with four spines, none of which are apical, genicular 

 spine rather short; tibiae equal to the femora in length; tarsi consider- 

 ably shorter than the femora, metatarsi almost equal to the remaining 

 tarsal joints. Posterior femora witli four spines on each margin, 

 genicular spine of moderate size; tibiae one and one-fourth the length 

 of the femora; tarsi three-fifths the length of the tibia', metatarsi 

 equal to the remaining joints in length, the two lateral and two ven-

 simihii- to the male, except that the anterior and antero-lateral margins 

 form a continuous arc. Wings equal to the tegmina in length when in 

 repose; costal margin .sti'ongly arcuate apically, apex subangulate; ulnar 

 vein bearing about sixteen conq)lete lami and a number of incomi>lete 

 ramifications. Supra-anal plate produced, l)ilobate, the fissure -shaped.
