HEMIPTERA. VAN DUZEE. 57 
Color yellowish-green, becoming darker or olive green above 
but still with a yellow tint. Elytra usually touched with blueish at 
base of the clavus and washed with the same color near its apex. 
Vertex with the median line and a spot either side pale. Pronotum 
with the median line and a spot behind each eye pale. Scutellum 
with a pair of pale diverging discal lines which are frequently 
wanting. Elytra when fully colored with the inner nervures and 
some connecting spots whitish, outlining in an irregular way sev- 
eral elongated green areoles: four on the clavus of which two are 
basal, one medial and one apical, and a row of three long ones on 
the inner margin of the corium. Membrane faintly smoky-hyaline 
with green nervures and a row of whitish spots on either side of 
the transverse nervures. Wings hyaline, highly iridescent, the 
hervures white. Beneath touched with blue-green on the clypeus 
and legs. Margins of the venter stronger yellow, the tergum lined 
with dark green. 
Described from numerous examples taken at San Diego in 
April and June and at La Jolla in J anuary, the latter, mostly males, 
were taken on Ceanothus. This’may prove to be but a color vari- 
ety of alboneura but it seems sufficiently distinct. Here the ner- 
vures are never evenly white, the pale color seems washed on 
broadly and irregularly giving the insect a mottled appearance. 
Those taken later in the season were mostly females. 
385. Empoa querci Fitch.- San Diego, May. Differs from east- 
ern examples in having the tergum mostly black. 
386. Hmpoa querci var. 6-notata n. var. 
Differs from typical querci in being tinged with yellowish 
above. The scutellum is fulvus, the elytra have the commissural 
hervure and a line along the claval suture yellow, and three pairs 
of fuscous spots along the commissural margin, the first at the tip 
of the scutellum, the second on the middle of the claval margin and 
€ posterior pair represents the inner end of the usual transverse 
Tow, found in querci at the base of the apical areoles ; the remain- 
der of this row is poorly defined in this variety. 
_, Described from two males taken at Alpine in June. This is 
quite distinct from var. bifasciata of Gillette and Baker. 
387, Eimpoa tenerrima H. S. Two examples taken at San Diego 
in May and June, and one from Alpine, taken in October. I 
feel some doubt about this determination. 
388. E'mpoa commissuralis Stal. San Diego and Cuyamaca Mts., 
May to October. 
389. Krythroneura obliquua Say. San Diego, May; Alpine, Octo- 
ber. These are pale specimens in which the red is replaced 
with yellow. 
390. Erythroneura obliquua fumida Gill. San Diego, May. These 
also are paler than eastern specimens. 
391, Erythroneura obliquua dorsalis Gill. Alpine, June 4th, 1918, 
in two examples the dorsal stripe is blood-red. 
392. Erythroneura comes coloradensis Gill. Lakeside, May; Al- 
pine, October.
