Type: ?; Bartica, British Guiana. May 9 1901. (R. J. Crew.) 

 [A. N. S. Phila.] 



Apparently allied to E. crassa Saussure from Mexico, and E. brevis 

 Brunner* from St. Vincent; differing from the former in the smaller 

 size, comparatively longer pronotum, the sub-acuminate apex of the 

 tegmina, and in the deeply incised supra-anal plate; from the latter 

 in the different character of the supra-anal plate and the smaller size. 



Size medium ; form ovate. Head with the interspace between the eyes about 

 equal to that between the ocelli ; eyes elongate, pyriform, strongly depressed 

 posteriorly; antennae not equalling the body in length. Pronotum pentagonal 

 in outline; anterior margin sub-truncate; posterior angle obtuse; lateral portions 

 considerably depressed and with the angles broadly rounded. Tegmina elongate 

 ovate, not equalling the body in length, apex subacuminate, ana! sulcus arcuate, 

 very slightly sinuate, anal field less pyriform than usual in the group. Wings 

 short and broad ; anterior ulnar vein with rami extending almost to the base. 

 Supra-anal plate triangular, the apex deeply fissate. Cerci exceeding the supra- 

 anal plate in length, somewhat depressed, bluntly acuminate. Subgenital plate 

 slightly produced, rotundate, the apex entire. Anterior femora with the proxi- 

 mal portion of the anterior lower border with five or six large spines, the distal 

 portion with a series of minute spines; tibise about three-fourths the length of 

 femora; tarsi with the metatarsus about the length of the remaining joints 

 united, and wilh its lower surface supplied with two rows of minute denticles. 

 Median femora with the lower surface supplied with three stout spines; tibiae 

 about equal to the femora in length ; metatarsi slightly shorter than the remain- 

 ing tarsal joints, the lower surface being supplied with two longitudinal denticu- 

 late ridges. Posterior femora with the lower margin supplied with three large 

 spinesf; tibia? slightly exceeding the femora in length; metatarsi comprising 

 about three-fifths of the entire length of the tarsi, and supplied on the lower sur- 

 face with the two denticulate rows present in the metatarsi of the other limbs, 

 pulvilli small and apical. 



General color reddish brown, sprinkled with spots of dark umber; pronotum 

 rather uniformly dotted with the deeper color ; tegmina w'ith the blotches evenly 

 distributed, the basal section of the principal veins rather strongly marked. 

 Under surface of the body pale ochraceous, the apex of the abdomen reddish 

 brown. Eyes, antenna- and interocular space uniformly blotched with umber.
