HEMIPTERA. VAN DUZEE. 11 
Family PYRRPOCORIDAE 
87. Largus cinctus H. S. Not uncommon on bushes and trees. 
These are darker than the typical cincltus and may prove to 
be convivus Stal. The young of this species were described 
by Kirkaldy as the young of Stiretrus anchorago, a Penta- 
tomid! 
Family TINGIDIDAE 
88. Piesma cinerea Say. May to August; not uncommon. Some- 
times of a greenish white color but such paling is quite char- 
acteristic of the arid regions. 
89. Corythucha fuscigera Stal. San Diego, May; on chaparral. 
90. Corythucha marmorata Uhler. Alpine, October; on a wild 
sunflower, perhaps a Hieracium. Also taken in June. A 
third species of this genus inhabits the mountain balm and 
a fourth the Heteromeles but I have not had time to work 
these out. 
91. Gargaphia opacula Uhler. Lakeside and Mussey’s, August to 
October. Abundant on willows along the river. 
92. Physatochila plexa Say. Lakeside, October; one example. 
93. Teleonemia nigrina Champ. April to October; common on a 
yellow flowered Leguminose plant allied to alfalfa, also 
found on Rhus laurina. 
Family PHYMATIDAE 
94. Phymata erosa parva Handl. Common on Eriogonum and 
other flowers. As I determine this subspecies it is a small 
strongly marked form with the sides of the pronotum but 
little emarginate and the humeral angles more rounded, not 
strongly prominent. 
95. Phymata erosa severini Handl. Common. June to October. 
This is a small form like the preceding but the humeral 
teeth are more prominent with the pronotal sides more 
deeply notched. The colors are paler in this form but the 
males are clearly marked with a black band across the abdo- 
men, another across the humeri and a dot on the margins of 
the pronotum anterior to the sinus. It is our most common 
form. 
96. Phymata erosa arctostaphylae n. subsp. 
Very close to fasciata Gray, a little larger, sides of the abdom- 
en more strongly angled, the humeri more produced, almost alate, 
the anterior teeth much more prominent than the posterior; the 
submarginal posterior carina distinct; apical lobes of the head 
longer and more pointed. Color dark mahogany brown with indi- 
cations of the transverse black bands across the broadest part of 
the tergum and on the hind margin of the pronotum; beneath clear 
red, almost sanguineous. Length 9 mm. greatest breadth of the 
abdomen 5 mm. 
Characterized from a single female beaten from a bush of the 
broad-leaved mountain Arctostaphylos, or manzanita, near Morena
