considered vitreus are not Westwood's species, an examination of the 

 measurements of the two making this fact very apparent. The male 

 of vitreus has the subgenital plate acuminate instead of truncate as 

 described by Brunner.

This species may be separated from vitreus Westwood by its larger 

 size and more ample tegmina and wings. As no males have been 

 examined it is possible that it represents the female of E. pictus Saus- 

 sure," based on the male only. 



Size large; form as usual in the genus. Head strongly elevated, 

 the occiput and vertex sharply ascending, the interocular region quite 

 narrow, about half as wide again as the frontal costa at its widest part; 

 frontal costa narrow, strongly compressed at the ocelli, subequal below 

 except for a slight widening at the median ocellus, rather deeply sulcate ; 

 antennae very short, the insertion strongly crowded between the eyes 

 and the frontal costa; eyes subelliptical, moderately prominent. 

 Pronotum selliform; cephalic margin sinuato-truncate, caudal margin 

 arcuate ; prozona with three distinct transverse ridges, metazona reticu- 

 late with a slight median carina; lateral lobes slightly deeper than 

 long, cephalo-ventral angle obtuse, caudo-ventral angle rectangulate, 

 ventral margin oblique, sinuate. Tegmina large, exceeding the apex 

 of the abdomen by more than one-fourth their length, considerably ex- 

 panded at the tips, costal margin strongly arcuate distad,apex oblic^uely 

 truncate. Wings equal to the tegmina in length. Ovipositor valves 

 punctate, the margins crasso-dentate ; subgenital plate apically acute 

 with a slight median longitudinal depression. Caudal femora slender, 

 falling slightly short of the tips of the ovipositor valves, the distal half 

 slender, dorsal and dorso-lateral carinse sparsely serrato-dentate; tibiae 

 slightly sinuate in the proximal half, external spines decidedly smaller 

 than the internal ones; metatarsi slightly shorter than the remaining 

 tarsal joints, superior carinse serrato-dentate. 



General color (specimen discolored) bistre, the face washed with 

 cinnamon; tegmina tawny olive, with two faint oblique apical bars of 

 umber parallel with the apical margin; caudal femora with faint traces 

 of several annuli of a light shade; caudal tibiae marmorate with umber 

 on a wood brown ground.
