? H. serrata Robineau Desvoidy, Myod., 389.—France. 
S. Length, 34—4 mm. Sides of the front gently concave, in its narrowest 
width about equal to one-fourth the length of the front from the foremost ocellus to 
the base of the antenne ; in the middle a narrow, dark brown stripe; a single row 
of slender bristles on each side. Antennge brownish red ; second joint slightly tumid; 
third joint a little longer than broad, with its inferior angle rectangular ; arista swollen 
at the base (which is black) ; the pectinations long. The narrow sides of the front, 
and the still narrower facial and genial orbits, silvery gray, with a slight yellowish 
cast ; facial foveze and cheeks blackish, the latter clothed with yellowish hair. Palpi 
black, the inner surface and immediate base more yellowish; gently spatulate in 
shape, nearly as long as the proboscis, and extending two-third of their length beyond 
the oral margin. Mesonotum.sub shining black in ground color, but mostly con- 
cealed beneath a brownish dust, and with only taint indications of stripes, Dust on 
the pleurss more grayish. Abdomen with similar dust; in the middle with a more 
brownish, sub-interrupted stripe, and narrow dark posterior margins to the segments.

or luteous, the hind tibize and tarsi blackish brown ; hind tibiz on the posterior sur- 
face with noticeable, erect, subapical bristles, hind tarsi about as long as their tibiae, 
the first three joints widened from base to tip of each, so as to form a distinct serra- 
tion on their inner acute angles, each of which terminates in a long hair. Wings 
with a light blackish tinge (due to microscopic pubescence), the immediate base yel- 
lowish ; first posterior cell rather symmetrically narrowed to terminate broadly at 
the extreme tip of the wing. 
Q. Front straight on the sides, its width about equal to one-half the distance 
from the toremost ocellus to the base of the antennz ; the median deep brown stripes 
about as wide as the lateral pruinose portion. Palpi yellow, with the margins and 
tip blackish. Legs more yellowish ; hind tarsi regular ; pulvilli and claws small.
