Amer. Ent. Soc., 70: 146. 
Remarks. — I have not seen the type of this species, nor had Brad- 
ley. It is a small species, comparable in size to pulcherrimus and 
insolitus. It is reported to have a short pronotum and unarmed hind 
tibiae, as well as a color pattern distinct from that of other species.

Description (from Haupt, 1930).- — Length 7 mm. Yellowish- 
brown, the following black: head, apical half of antennae, tergites 1, 
3, and 4, apex of hind femora, and outer base of hind tibia. Fore wing 
with two dark brown bands. Hind tibiae with a whitish area behind 
the black base, tips of front and hind coxae also whitish. Whole body 
with short, thick whitish hair ; eyes and wings hairy. 
Wings (Haupt’s fig. 64) yellowish-hyaline, a brown transverse 
band before the middle and one before the apex. Fore wing with three 
cubital cells, the second somewhat pentagonal, the third trapezoidal, 
the latter removed from tip by its own length. Radial cell longer 
than second and third cubital cells together, also somewhat higher 
than these. Pterostigma cell-like, translucent, somewhat attenuate. 
Lower section of basal vein about twice as long as upper and weakly 
arched; transverse median vein interstitial. Hind wing with trans- 
verse median vein short, oblique, reaching media more than its own 
length before origin of cubitus. 
Head thick, flattened and weakly concave immediately behind the 
eyes, temples barely developed. Ocelli large, forming a weakly acute 
angle in front, postocellar and ocello-ocular lines equal. Front 
strongly swollen, eyes thick, their inner margins subparallel, the eyes 
together about equal to width of front. Antennae filiform, relatively 
thick, third segment somewhat shorter than scape. Clypeus short, 
trapezoidal, its entire anterior margin weakly arcuately concave. Seg- 
ments of maxillary palpi very long, third segment about ten times as 
long as thick (Haupt’s fig. 65). Pronotum short, hind margin obtuse- 
ly angled, sides parallel, with distinct longitudinal swellings. Meso- 
scutum twice as long as pronotum medially; scutellum and metanotum
