E. yrnEAris, Lec. Form more parallel, pubescence coarse, 
color uniformly brown; surface punctulate. Length 1.3 to 
1.6 mm, Plate Al, Fig: 107: 
flead trapezoidal, wider than long, eyes large, tempora 
slightly arcuate, convergent, base sinuate, with a median 
impression, frontal margin straight; supra-antennal tubercles 
strong, angularly rounded, occipital foveze far apart, in line 
with the posterior limits of the eyes; sulcus parallel to the 
sides, where it is deepest, wider toward the frontal margin; 
from this point it presents a surface slanting upwards to the 
triangularly elevated vertex. Anfenne nearly as long as the 
head and prothorax together, first joint rather robust; second 
much smaller, third to eighth equal, transversely globular; 
ninth twice as wide as long; eleventh as wide asthe tenth, and 
one-half longer than wide, annulate near the acute tip. Pro- 
thorax slightly wider than the head, widest before the middle, 
sides slightly sinuate anteriorly, very convergent, the middle 
evenly arcuate, behind nearly straight; neck not half as wide 
as the middle, base two-thirds of the total width, disk broadly 
convex, median sulcus fusiform, widest and deepest near the 
center, connected with the transverse doubly-arcuate sulcus; 
the lateral fovez are large and deep. A/ytra rather flat in- 
side of a triangle limited by the base and two lines drawn from 
the shoulders to the posterior end of the suture, the remaining 
triangles being more convexand declivous; across the shoulders 
they are as wide as the prothorax, and near the tip are one- 
fifth wider; sides divergent, nearly straight behind; discal lines 
abbreviated before the middle, sutural lines deep, interval very 
slightly dilated behind the middle, the three basal fovee rather 
deep. Aébdomen broadly margined, sides of the first three 
segments parallel; carine of the first and second segments 
short, including one-fifth of the total width. The under sur- 
face of the head and abdomen more strongly punctured. 
é, last ventral lozenge-shaped, punctate, carinate in the middle. 
Habitat. East of the Mississippi river.
