three on each side are nearly straight and directed forward, while 
the hinder two are curved and directed backward. A pair of 
curved, divergent, anteriorly directed ocellar bristles. Face and 
palpi pale silvery, the palpi sparsely clothed with small bristles | 
on lower portion; cheeks, occiput, and proboscis dilute tawny, 
occiput above bordered with a row of whitish bristles. Thorax 
slightly silvery cinereous, with three golden brown vitte, clothed 
with whitish bristles and hairs; humeri and pleurz concolorous; 
scutellum nearly concolorous, rather triangular in shape, with 
four bristles, the anterior pair longest, the apical pair hardly 
decussate., Abdomen brownish, flattened, curved under, some- 
what ovate in outline, rather pointed behind, quite sparsely 
clothed with short bristly hairs, and with longer bristles on hind 
margins of segments. Legs pale brownish fulvous, claws short 
and blackish. Wings broad, rather long, from apical three- 
fourth tapering almost equally on anterior and posterior borders 
toa blunt apex. Picture of wings almost the same as that of 
E. Mexicana, figured by Loew in Monographs, iii, pl. x, fig. 28. 
Differs from the figure only as follows: Second vein ends 
about in middle of margin of hyaline spot third from tip 
on anterior border; of the three marginal hyaline spots of 
second posterior cell, the two end ones are somewhat elongated 
inward like the middle one; the proximal one of the two costal 
hyaline markings in marginal cell does not extend inward below 
the second longitudinal vein, or is represented by only the 
merest dot, and the distal one does not quite reach second vein; 
one (the right) wing shows two hyaline drops about middle of 
discal cell, the distal one smaller, while in the other wing the 
smaller distal drop is represented by two very small dots in a 
line transverse to the wing; five hyaline drops in third posterior 
cell, two bordering on posterior margin of wing, two approxi- 
mated to fifth-vein, and one bordering on the sixth (anal) vein 
considerably removed from the margin; four obscure hyaline 
drops in the less infuscated anal angle of the wing, inside the 
anal or sixth vein; the coloring becomes more or less dissolved 
toward the wing base, the second basal cell being mostly clouded 
on distal half. Third vein bristly to a point about opposite or a 
little beyond termination of second vein, first vein bristly nearly
