■ To this group belong E. conspersa and E. agathina, of which 

 species single specimens are at hand. More material may show 

 these forms to be generically distinct. 



The present species has the tegmina narrower than in con- 

 spersa, less strikingly marmorate, with an irregular clustering of 

 black dots mesad which are not found in that species, neither is 

 the area of the costal veins solidly colored or as dark, showing 

 only nuinerous irregular dark punctae. The coloration of agathina, 

 which is a larger and heavier insect, is much darker and of a dis- 

 tinctly different type. 



Type. — cf ; El Credo, Cauca, Colombia. Elevation, 1000 feet. 

 February, 1907. (M. G. Palmer.) [Academy of Natural Sci- 

 ences of Philadelphia, Type No. 5345.] 



Size small for the group, medium for the genus; form moderately broad. 

 Interocular space wide, nearly as wide as interocellar space, much wider than 

 space between antennal sockets; face flattened; ocelli large, well defined, with 

 flattened surfaces forming an obtuse-angulation with plane of face. Pronotum 

 convex, lateral portions moderately declivent latero-cephalad, greatest width 

 mesad; cephaUc margin rather evenly convex, broadly but feebly thickened to 

 point of greatest pronotal width, where the angle formed is sharply rounded at 

 slightly more than ninety degrees, latero-caudal margins moderately convex 

 convergent, then concave convergent to the distinct, bluntly rounded, meso- 

 caudal production. Tegmina elongate, width subequal from apex of anal 

 field to a distance equalling the length of that field; rounded apex nearer the 

 costal margin. Wings with numerous, irregular costal veins; ulnar vein with 

 numerous (18) incomplete and few (4) complete branches. Dorsal abdominal 

 segments with latero-caudal angles all blunt and not produced. Supra-anal 

 plate with all but narrow proximal portion subchitinous, about two and one- 

 half times as broad as long; lateral margins feebly convergent, nearly straight 

 to the broadly rounded, nearly rectangulate latero-caudal angles, distal margin 

 transverse, feebly convex. Cerci moderately elongate, tapering moderately 

 to the very slender distal third, joints distinct but very weakly crenate. Sub- 

 genital plate with sinistral margin moderately convex to beyond mesal point, 

 dextral margin decidedly concave.-® Cejihalio femora with ventro-cephalic 

 margin armed proximad with a few heav}', well-spaced spines, succeeded by a 

 row of microscopic widely spaced piliform spines, with a single hcav}' and very 

 elongate distal spine; other ventral femoral margins moderately supplied with 

 heavy spines. Caudal metatarsus very elongate and slender, equal to com- 

 bined length of succeeding joints, armed along each ventral margin with a 

 closely-set row of minute spines; four proximal tarsal joints each with a round 

 distal pulvillus, the surface of which is produced caudad. Large arolia present. 



-^ In this specimen the subgenital plate is apparently distorted. A single 

 microscopic style is apparent in the concavity of the dextral margin.
