pile of their tarsi black. The coxae and femora are long, 
thickly bushy pilose; the pile is pale golden yellow but 
the hind femora vent rally and apically have a tuft of 
fine, long, black hair. Wings: anterior border of the 
wings dark brown, extending almost to the apex of the 
first posterior cell leaving the loop of this cell entirely 
clear. The costal cell and the basal portion of the stig- 
mal area and also the subcostal cell are more yellowish. 
Abdomen: black, the first segment with a posterior band 
of yellow tomentum; the second is entirely black pilose 
upon the posterior half with golden yellow pile anteriorly 
and laterally. The third segment has a prominent, nar- 
row, basal margin of yellow tomentum, the remainder of 
its pile short setate and black, except medially on the pos- 
terior margin where it becomes reddish. Fourth seg- 
ment with a similar band of yellow, basal tomentum, the 
remainder of its pile entirely golden red. Pile of the

Quichuana nigra n. sp. 
A rather large black species which is related to bezzi 
Ceresa. It clearly lacks brown color below the spurious 
vein. From parisii Ceresa it differs in the quite black 
tibiae. Length about 12 mm. 
Female. Head: the face is brownish black, the sides 
entirely pubescent without bare sublateral stripes. The

facial pile is abundant and long and yellow. The front 
and upper part of the face are quite protuberant. The 
front is shining black with an obscure reddish line down 
the middle of the lower part ; the frontal pile is abundant 
and except for two or three black hairs it is entirely 
brassy yellow but this pile nowhere obscures the ground

coarse yellow micropubescence on the upper part of the 
front a little way below the ocelli. This triangle is con-
