194 Annals Entomological Society of America |Vol. VIII, 
Described from nine females and three males collected by 
the author October 8, 1914, at Clarksville, Tennessee, from 
small grasses on dry upland. 
Athysanus (Stirellus) villicus n. sp. (Pl. XIX, figs. 24, 25). 
Near punctatus. With two large, round, black spots on anterior 
margin of vertex next eye. An orange or fuscous brown band on 
posterior half of pronotum. Female ovipositor rather strongly exserted. 
2.6-3. mm. long and 1. mm. broad. 
Vertex convex, as long as width between the eyes, as long as 
pronotum, one-fifth longer on middle than at eye, bluntly angulate, 
margin blunt, front convex in both diameters, rapidly narrowing to 
the parallel margined clypeus. Pronotum two and one-third times as 
broad as long. The elytra subhyaline, narrowed toward the apex, 
venation weak, distinct, the central anteapical cell divided by a cross 
. yer 
Vertex, anterior half of pronotum and scutellum yellow, posterior 
half of the pronotum and the elytra pale orange or infuscated brown, 
two large, round, black spots on anterior margin of vertex next the 
eye, and two minute, fuscous points at apex; venation pale, face yellow, 
the front more or less infuscated with a median stripe and lateral 
arcs pale, a black point beneath each ocellus, venter mostly pale. 
Q Ultimate ventral segment of abdomen one and one-half times 
as long as penultimate, twice as broad as long, lateral angles rounded, 
posterior margin gently emarginate, but sometimes appearing angularly 
excavated, owing to the curvature, strongly curved over the ovipositor, 
with a small, rounded median tooth. Ovipositor rather strongly 
exserted. 
o& Valve convex, twice as long as preceding segment, strongly 
convex on anterior margin, subangulate posteriorly, over twice as 
broad as long; plates twice as long as valve, nearly as long as broad, 
side margin nearly straight, tips acute, slightly exceeded by the stout 
pygofers which are heavily clothed with bristles. A basal median 
fuscous line on each plate. 
Described from seven females and ten males, collected by 
the author at Clarksville, Tennessee, September and October, 
1912, on Aristida gracilis, in company with Deltocephalus pyrops. 
Phlepsius optatus n. sp. (Pl. XIX, figs. 13, 14). 
Very near fulvidorsum in shape, size and genital characters, but 
paler and differing in details. Length 5. to 6. mm., breadth 1.6 mm. 
Vertex convex, nearly three and one-half times as broad as middle 
length, about one-fifth longer on apex than next eye, one-third as long 
as pronotum, the margin blunt, front three times as broad between 
ocelli as at clypeus, slightly longer than broad, convex, the sutures 
convex, elytra long, appressed at tip.
