HEMIPTERA. VAN DUZEE. Ball 
oval, scarcely sinuated before. Rostrum attaining the apex of the 
hind coxe. Antenne short; basal joint just passing the apex of 
the head; second as long as the pronotum and eye together when 
viewed from above; third and fourth together as long as the sec- 
ond in the female, a little shorter in the male. Pronotum short, 
more narrowed anteriorly in the male, the sides straight; callo- 
sities narrow in the female, nearly obsolete in the male, surface 
polished. Base of the scutellum narrowly exposed. Elytra nearly 
parallel, flat; cuneus long and acute at apex, nearly horizontal. 
Color piceous or black, the elytra usually a little paler. An- 
tenne testaceous-yellow, dusky at apex. Elytra with a broad white 
band across just beyond the tip of the scutellum which may be 
much reduced in the male; base of the cuneus broadly white; mem- 
brane uniformly smoky, iridescent, its nervures black. Legs pale 
yellow or fulvous, the posterior femora fuscous or piceous; tibiz 
immaculate, the spines concolorous, the tarsal claws black. Ros- 
trum pale with the tip black. 
Described from numerous specimens taken on Ceanothus in 
the spring, March to June. This species is very distinct by its pol- 
ished black color with two conspicuous transverse white bands. 
193. Leucopoecila albofasciata Reut. Common in alfalfa fields 
throughout the year. 
194. Maurodactylus semiustus n. sp. 
Soiled greenish white more or less tinged with fulvous; mem- 
brane uniformly smoky; above clothed with short dark deciduous 
hairs. Length to tip of membrane scant 3 mm. 
Head short, vertical, about two thirds the width of the hind 
margin of the pronotum, strongly tinged with fulvous; vertex 
broad, convex, polished; basal suture of the clypeus not distinct, a 
little above the base of the antenne. Rostrum almost attaining the 
apex of the hind coxe. Antenne rather long, more or less infus- 
cated; basal joint just passing the tip of the head, thickened at 
apex; second nearly as long as the basal margin of the pronotum; 
third and fourth together twice the length of the second, the third 
twice as long as the fourth. Pronotum short, transverse, the sides 
arcuated ; callosities moderately prominent; surface polished, quite 
strongly tinged with green on the disk of the callosities, the mar- 
gins more yellowish. Basal lobe of the scutellum narrowly ex- 
posed. Elytra concolorous, polished, with the black hairs more 
persistent. Membrane uniformly smoky but paler in the areoles, 
the nervures pale. Beneath are legs concolorous, the basal margin 
of the venter more greenish or this color may cover the pleural 
_ pieces. Tibial spines and apex of the tarsi black. 
Described from a good series swept from a low weed found 
growing on top of the rocky hills at Mussey’s, April 11th, 1914. 
This insect has much the aspect of a Tuponia and perhaps should 
be placed in that genus but in Reuter’s key to the genera of this 
tribe it runs directly to Mawrodactylus. The uniformly smoky 
membrane and greenish yellow color, below as well as above, will 
distinguish this tiny species.
