HEMIPTERA. VAN DUZEE. 5 
umn and winter a green form wanting the red band is 
common in alfalfa fields. 
Thyanta brevis Van D. Lakeside, October. Taken in numbers 
from a low Chenopodium growing along the river. 
Murgantia histrionica Hahn. Common everywhere on mus- 
tard and on “bladder pod,” the latter of which seems to be 
its native food plant here. It varies widely in color and an 
unusually dark individual has been described by Prof. Cock- 
erell as var. nigricans. 
Nezara hilaris Say. Common. 
Dendrocoris pini Montd. Pine Hill, October; several taken 
from pine trees. 
Podisus pallens Stal. Common throughout the year. This 
species is very close to maculiventris Say but the black ven- 
tral spots are much reduced and the form of the genital 
pieces is different. 
Zicrona caerulea Linn. Alpine and elsewhere, July, on Erio- 
gonum. 
Family ARADIDAE 
Aradus falleni Stal. Mission Valley, San Diego, July. 
Family NEIDIDAE 
Neides muticus Say. April to October; not uncommon. 
Jalysus spinosus var. wickhami Van D. April to October, oc- 
casional. 
Acanthopysa echinata Uhler. Lakeside and Alpine, May to 
July. This species inhabits a low spiny plant growing on 
dry granite soils among the bristly flowers and fruit of 
which it is wonderfully well concealed by its own spiny sur- 
face. 
Family COREIDAE 
Corynocoris distinetus Dallas. Alpine, July and October. 
These do not differ from eastern specimens. I hardly think 
this species can be differentiated from typhoeus. 
Narnia pallidicornis Stal. Abundant on cacti, especially the 
“ylate cactus,’ from March to October. 
Narnia (Xerocoris) wilsoni Van D. Not uncommon about 
La Jolla in August on the melon cactus or “nigger head.” 
Also Lemon Grove, February. 
Chelinidea tabulata Burm. Found on stag-horn cactus or 
Chollas, throughout the year. These western specimens 
show a strong tendency to darkening of the legs and anten- 
ne, thus exhibiting a decided approach to vittigera which 
may not be distinct. 
Ficana apicalis Dallas. Common in many localities; about 
half of the specimens have the connexivum immaculate but 
they do not seem to represent a distinct species. 
Dasycoris humilis Uhler. El Cajon, May, one example. 
Darmistus subvittatus Stal. Alpine, June; one example. 
Alydus pilosulus H. S. Lakeside, October, from the flats by 
the river.
