moderately wide, rather widely reticulated, with two rows of areolae; subcostal 
area rather closely reticulated; discoidal area more closely reticulated; sutural area 
unevenly reticulated, with two large areolae near the posterior end. Wings not 
longer than the abdomen. Length, 2.2 mm.; width, 9 mm_. 
Color: Body black. Legs yellowish; tips of tarsi fuscous. Antennae—first and 
second segments testaceous; third segment yellowish; fourth segment fuscous. 
Hood whitish, nervures more or less testaceous; membranous pronotal margins 
whitish, the nervures of four or five areolae on humeri brownish. Elytra whitish, 
with a rather broad, transverse, dark-fuscous fascia just before the middle on the

Head with, at most, five rather short spines. Antennae slender; the 
basal segment long; third segment very long. Rostral groove uninter¬ 
rupted, broad on the meso- and metasternum and closed behind; rostrum 
rather short. Pronotal hood large, extending prominently above the 
head. Membranous pronotal margins foliaceous, broadly rounded. Pos¬ 
terior portion of the pronotum abbreviated, obtuse at the tip. Elytra 
twice or nearly twice as long as the abdomen, broad, more or less widely 
reticulated, strongly rounded at the base and apex. Wings short or

Leptobyrsa explanata Heidemann (Plate VIII) 
Leptobyrsa explanata Heidemann, Proc. Entom. Soc. Wash., Vol. II, p. 105. 
Body short, oval in the female and more elongate in the female. Head rather 
short, with three frontal spines and two other more slender ones extending from be¬ 
hind the eyes towards the front. Antennae long, slender, finely pilose, the first two 
segments swollen; first segment twice the length of the second; third segment a 
little more than three times the length of the fourth. Pronotum feebly convex, 
coarsely punctured; membranous margins strongly rounded behind, reflexed, 
widening moderately at the sides, with two or three rows of areolae: hood not 
much inflated, covering the head (except eyes), with quite large areolae at sides 
near the top and smaller ones near the base, cristate and slightly tapering towards 
the front. The three pronotal carinae foliaceous; the median carina strongly 
raised, as high as the crest of the hood, rounded on top and slowly declining 
towards the apex of triangular portion of pronotum; outer carinae feebly raised, 
one-half as long as the median carinae. Elytra ovate, strongly rounded from base 
to apex, broadest behind the^ middle. Crest of hood, lateral margins of pronotum,
