3. Ovipositor two-thirds the length of the abdomen, anterior wings 
with a distinct white band, body entirely black, .fasciatus Ashm. 
Ovipositor one-half the length of the abdomen, wings sub- 
fuliginous with some whitish streaks, but without a distinct 
white band, body dark fuscous varied with ferruginous. 
aciculatus Cress. 
Hormiopterus claripennis sp. nov. 
Female. Length 4.5 mm. Ovipositor 4.25. Black, head, base of 
antennae, prothorax, tegulae and legs more or less ferruginous or fus- 
cous. Head more transverse than usual, about one-half wider than 
thick. Occiput and vertex shining and very finely and distinctly trans- 
versely aciculated; cheeks polished; face with a delicate sculpture and 
covered with sparse glistening hairs. Eyes very large, their long 
diameter more than half the head-height. Antennae very slender 
throughout, 30-jointed, the flagellar joints after the first decreasing in 
length, but the subapical ones are fully three times as long as thick. 
The joints are of even thickness and not easilj^ counted. Palpi long, 
pale yellow. Mesonotum smooth, except for the crenulate sutures and 
furrows. Pleurae very finely rugulose and whitish-hairy. jSIetanotum 
rugulose, with faint traces of ar eolation. Abdomen not quite as long 
as the head and thorax together, at the base two-thirds as wide as the 
tip of the metathorax. First segment two and one-half times as long 
as wide at apex, its surface coarsely longitudinally striated; basal two- 
thirds of second segment striated above, the striue reaching the tip 
laterally; the oblique impressions are long and reach the basal margin 
of the segment. Apical margin of the segments shining. Ovipositor 
black. Vvings clear hj^aline, the veins and stigTna piceous black. Sub- 
median cell longer than the median, reciTrrent nervure almost inter- 
stitial, being received by the very tip of the first (not second) cubital 
cell; sub-discoidal nervure interstitial; second abscissa of the radius 
one-half longer than the first and two-thirds as long as the second 
abscissa of the cubitus. Legs, including coxae, fuscous, the anterior 
legs, middle tibiae, and all tarsi and trochanters ferruginous. Posterior 
tibiae with a pale yellow annulus at the extreme base. 
One female, Douglas Co., Kansas, Sept., collected by Air. E. S. 
Tucker and sent by him for identification. 
The hyaline wings and general appearance of this species 
remind one of Honnius, but the neuration is that of- Hormiopterus.
