eleven-jointed, inserted on the middle of the face, the scape long, 
cylindrical, projected far above the vertex; in the male the six 
funicle joints each furnished with a long hairy ramus, the basal one 
being the longest, the others gradually diminishing in length to the 
last; the first funicle joint is very short, the following all long, at least 
thrice longer than the first; club long, fusiform, three-jointed. In the 
female the flagellum is subclavate, the first funicle joint being remark- 
ably long, almost as long as the five following joints together; the last 
five funicles are short and very gradually increase in length and width 
to the club, the latter composed of three joints. The thorax in the 
male is strongly developed, highly convex, resembling somewhat an 
Eucharid; in the female less strongly developed. Mesonotum trans- 
verse, smooth, polished, without trace of furrows. Scutellum longer 
than wide, rounded behind and highly convex. Axille transverse, con- 
vex. Metathorax short, smooth, the spiracles very large, rounded. 
Middle legs slightly the longest, their tibiw long, slender, cylindric, 
about one-third longer than the tarsi, the spur more than half the 
length of the basal tarsal joint, the tarsi stouter than the posterior 
tarsi, the joints after the first very short. The posterior femora and 
tibie are slightly dilated, the tarsi slender, unde and almost as 
long as the tibie. 
‘‘Abdomen, in both sexes, is small in Piianion to the thorax; in 
the male it is long, oval, aad of seven segments, the first much 
the longest, the others short, all of about an equal length; in the female 
it is subcompressed, composed of six segments, the hypopygium being 
plowshare shaped, the ovipositor slightly exserted; as in the male, the 
first segment is the longest. 
‘““Wings banded; the submarginal attains to the middle of the wing 
before jointing the costa, the costal cell being somewhat wide; the 
marginal vein is thickened and a little longer than the stigmal; the 
stigmal clavate curved upwards; the postmarginal is longer in the male 
than in the female.” 
Hexacladia smithii Ashmead. 
‘s Male.—Length, 1.8™"; wing expanse, 4"™. Head brownish-yellow, 
smooth, polished, the vertex fuscous; face very convex, with a few 
seattered, shallow punctures. Eyes broadly oval, brown. Antenne 
black, the scape pale rufous, with a dusky streak above, the six 
funiclar joints each furnished with a long hairy branch. Thorax 
black, impunctured, highly polished; collar brownish-yellow; scutel- 
lum shining, but microscopically shagreened. Anterior legs, in- 
cluding cox, brownish-yellow; middle and posterior legs black; in the 
middle pair the knees, tips of tibie, tibial spur, and tarsi are brownish- 
yellow. Abdomen black, the dorsum concave, probably unnaturally so 
in the dry specimen. Wings hyaline, with two transverse brown bands 
that do not extend entirely across the wing, terminating at about its 
center; the first and narrower is situated at about two-thirds the length
