brown, black bristly before; third joint blackish, less than three times as long 
as second, rather narrow; arista brown, darker at base and tip, microscopically 
pubescent, moderately thickened most of its length, distinctly 3-jointed, second 
joint elongate, sometimes almost geniculate; proboscis fleshy, shorter than bight 
of head, black, labella brownish, well developed ; palpi well developed, consid- 
erably thickened, curved uj) at tip, brownish yellow, black hairy with several 
black bristles on under surface before tip; occijuit cinereous, gray hairy, with 
fringe of black bristles on orbital margins. Thorax above silvery-cinereous, 
hairy and bristly, with three blackish vittse, indistinct in some lights, but dis- 
tinct when viewed from behind , scutellum silvery-cinereous, broadly reddish 
yellow on apical portion, with three pairs of strong macrochtefae, a weaker apical 
pair between the hind pair; humeri and pleurae silvery-cinereous. Abdomen 
blackish, silvery-cinereous, covered with short black bristles, broadly oval, first 
segment somewhat shortened, anal segment orange-colored ; segments one to 
three with a slight median depression, giving the appearance, in a side light, of 
a median vitta; first segment with a lateral marginal macrochaeta, and a median 
marginal pair; second with a median discal and marginal pair, and a lateral 
marginal one ; third segment with a median discal pair, and eight marginal 
ones above, with about three on each side below on the venter ; fourth segment 
with four marginal and a row of weaker discal macrochietse ; venter silvery, 
except the orange anal segment, with long bristly hairs. Legs blackish or 
l)rownish, silvery, except the tarsi, hairy; femora, and especially the tibiae, with 
black bristles, stouter on the tibiae; claws and pulvilli but little elongated. 
JVings longer than abdomen, grayish hyaline, veins brownish, with very small 
costal spiTie, third vein slightly spiny at base ; apical cell open, terminating con- 
siderably before tip of wing ; fourth vein bent nearly at a right angle, not sharply 
bent, but rounded, without stump or wrinkle, distal two-thirds of apical cross- 
vein curved backward; hind cross-vein long, oblique, a little crooked, nearer 
the bend of the fourth vein ; tegulae nearly white; halteres fuscous, yellowish 
at base. Length 10 mm. ; of wing 8.5 mm. 
De.scribed from one specimen received from Mr. Chas. Robertson, 
Carlinville, 111. This species may be looked upon as connecting the 
two genera, Frontina and Acroglossa. It has the arista nearly as in 
Acroglossa, sometimes subgen icnlate, while it pos.sesses the proboscis 
of Frontina. In general appearance it greatly resembles Acroglosm 
hesperidarvm. The whole fourth abdominal segment, however, is 
reddish or orange. It further differs from ^4. hesperidarum as fol- 
lows : the cheeks do not have bristles, but they are clothed with fine 
bristly hairs. The sides of face are golden, and the first abdominal 
segment bears a median j)air of macrochaetie on its hind margin, as 
well as the second segment, though they are weaker. This specimen, 
a % (?), also has the third antennal joint scarcely three times the 
length of the second. 
Kiplioiia u. sp. 9- — Deep golden, cinereous. Eyes dark 
brown, bare, nearly reaching the oral margin below; front and face nearly equal 
in width, occupying one-third width of head; front of a brassy-golden color.
