164 THE AMERICAN NATURALIST. [Vor. XXXV. 
the flagellum in some specimens more or less reddish. Wings 
slightly blackish, covered with minute black pile; stigma red- 
dish, veins dirty yellow. Pile covering the body grayish ful- 
vous, long and erect on the mandibles, antennal scape, head, 
thorax; pleurze, pectus, scutellum, base of petiole, and femora, 
elsewhere very short and appressed. 
Mandibles short, covered with small piligerous punctures, 
curved only at the base, thence becoming broad and flat, with 
distinctly convex inner margin and terminating in abrupt rather 
blunt tips. Head covered with punctures like those on the 
mandibles. Eyes and ocelli very small, not projecting ; cheeks 
and posterior orbital region broad. Lateral ocelli separated 
by a space about equal to that which separates each lateral 
ocellus from the eye. Frontal caring prominent, arcuate 
below the lateral ocelli, and separated by a rather broad 
longitudinal furrow. Anterior half of mesonotum with a dis- 
tinct smooth longitudinal line and distinct lateral furrows 
extending to the insertion of the scutellum. Scutellum with- 
out a furrow on its posterior surface. The piligerous punc- 
tures covering the mesonotum and scutellum are small and 
evenly distributed, those on the pleurz a little larger and more 
scattered. Metanotum declivous, slightly concave, finely punc- 
tate, and bearing little pile. Petiole twice as broad as long, 
convex above and behind, more concave anteriorly ; posterior 
angles not projecting and covered with very short appressed 
pile, contrasting with the long and often dense erect pile on the 
basal ventral and basal dorsal surfaces of the same segment. 
Abdomen short, cylindrical, and laterally compressed, its surface 
minutely punctate; pile everywhere, even at the tip, and on the 
hypopygium, very short and appressed. Hypopygium armed 
with the usual short, slightly recurved teeth. In some speci- 
mens the red of the abdomen even on the dorsal surface is more 
or less suffused with black, especially near the middle of the 
different segments. Fore-wings reaching to the tip of the abdo- 
men or even a little beyond. Venation very similar to that of 
E. schmitti (vide Fig. 1). Legs short, posterior pair not reaching 
the tip of the abdomen. Middle metatarsus a little more than 
half the length of the middle tibia. Denticles of claws vestigial.
