not reaching much beyond the apex of abdomen; the disk moderately 
densely pubescent, the speculum very distinct, the basal area with sparser, 
somewhat coarser but more hyaline setae, the costal cell pubescent except 
next to the vein; marginal fringe very short but dense; submarginal vein 
reaching to the middle of the costal margin, almost straight and some- 
what thickened near its apex; marginal vein quadrate-punctiform; the 
stigmal rather long, straight and with a slender, short spur at apex; post- 
marginal vein somewhat longer than the stigmal, the angle between these 
two veins acute; costal cell of hind wings moderately wide and extending 
to the hooklets. 
Head and thorax with a very finely reticulate, moderately lustrous sur- 
face, the face more lustrous and with a considerably coarser reticulation ; 
frontovertex with fine pin-punctures. Pubescence of head and body short, 
fine, appressed, dark-colored and inconspicuous; setae of the mesosecutum 
seriately arranged, those on the axillae and scutellum sparser yet rather 
numerous. Coloration metallic. 
Male. Very similar to the female, but the antennae are only eight- 
jointed, the funicle with five joints, and the club solid.

Synaspidia pretiosa n. sp. Figs. 2 and 3. 
Female. Head with the whole dorsal surface sloping forward and 
downward nearly at right angles with the longitudinal axis of the thorax; 
as seen in frontodorsal view, it is strongly rounded on the sides, subtrun- 
eate in front, the occipital margin broadly roundly emarginate; as seen 
from in front, distinctly wider than long, strongly rounded on the sides, 
with the cheeks gibbously convergent towards the rather small mouth. 
Occiput rather deeply concave, its dorsal margin very acute; eyes large, 
hardly a third longer than wide, their outline strongly rounded except at 
the inner orbits, their posterior margin contiguous to the oeciput; fronto- 
vertex narrowest at the anterior ocellus, slightly widening anteriorly and 
more abruptly widened at the posterior ocelli; ocellar triangle moderately 
acute, the distance between the posterior pair of ocelli equal to about 
three-fourths of the distance between either and the anterior ocellus; the 
posterior pair contiguous to the eyes and removed about one-half their 
own diameter from the occipital margin. Serobal impression large and 
occupying nearly the whole face, but rather shallow, indefinitely bounded 
on the sides, but definitely limited above by the angle between frons and 
face; the prominence between the antennae low and weakly convex, oval 
in outline and about twice as long as wide; the scrobes proper in the 
form of linear grooves on each side of the prominence, but uniting above 
and forming the bottom of the whole impression in its dorsal half. An- 
tennae and mandibles as in figure 2; maxillary palpi short, thickest at 
apex of the second joint, the first two joints nearly equal in length, the 
second about one-half longer than thick, the third distinetly smaller than
