HEMIPTERA. VAN DUZEE. 37 
have transverse elytral maculations. In some examples of califor- 
nicus the disk of the mesonotum is distinctly castaneous. 
220. Oliarus complectus Ball. Abundant everywhere. There are 
two forms of this species. In the more typical the meson- 
otum is black with the carine at times ferruginous; in the 
other the mesonotun, or at least the median compartments, 
is castaneous or at times almost sanguineous. In some ex- 
amples the elytra are milky hyaline but ordinarily they are 
hyaline or more or less infuscated. This species has also 
been found in the east. 
221. Oliarus fidus n. sp. 
A little larger than complectus; short and stout; black, elytral 
nervures heavy and punctate. Length 4-5 mm. 
Vertex nearly quadrangular, scarcely longer than broad, but 
little surpassing the eyes; hind edge deeply emarginate; apical 
compartments broad, convex; sides rounded, not obviously sub- 
angled as in many of our species; clypeal suture indistinct ; median 
carina distinctly forked at the apex of the head; mesonotal keels 
prominent, the four lateral regularly arcuated. Male pygofers 
with a shallow notch armed with a short blunt tooth, the sides reg- 
ularly arcuated; styles slender, strongly curved from their base 
about an ovate opening, meeting above and then abruptly reflex- 
ed, curving backward and outward under the lateral projections 
of the dorsal plate, the latter narrow and distant, not contiguous 
as in many species. 
Color black, the carine of the head and pronotum pale. Ros- 
trum, trochanters, knees, tibize and tarsi testaceous; slender mar- 
gins of the abdominal segments pale; genital segments pale brown. 
Elytra milky hyaline, nervures strongly dotted with fuscous and 
armed with black bristles making them conspicuous, the transverse 
veinlets infuscated. In fully colored females there is a row of 
three fuscous spots in the costal areole, an oblique row of three 
on the transverse veins of the clavus and middle of the corium, 
and some small faint clouds in the anteapical areoles. Stigma 
small and inconspicuous. 
Described from numerous examples taken on the rocky hillside 
south of the railway station at Foster on May 24th, 1913. 
222. Cixius cultus Ball. Found occasionally everywhere but more 
frequently near the coast; May and June. 
Genus Platycixius n. gen. 
Allied to Cixvius; head but little narrower than the pronotum ; 
eyes narrow, oblique, feebly emarginate beneath. Vertex large, 
depressed, with a median carina and the lateral and anterior mar- 
gins carinately elevated, base feebly arcuated. Front large, scarce- 
ly longer than broad, ecarinate, base as broad as the apex, tumid, 
sides arcuated, laminate outwardly, frontal ocellus conspicuous; 
clypeus tumid, apparently ecarinate. Pronotum longer than in 
Civius, tricarinate, the lateral carine running oblique and straight 
to the hind margin, behind the eye is a callous apparently connect-
