TRANS. S. D. Society NATURAL HISTORY 
Ceratocapsus setosus Reut. One specimen that seems to 
differ in no respect from Florida specimens in my collec- 
tion except that it is a little darker, was taken by me in 
the city park, San Diego, in May, 1918. 
Lopidea marginata Uhler. Abundant on the chaparral 
throughout the summer. An examination of the Uhler type 
now in the collection of the California Academy of Science 
shows that my former determination of this species as the 
pale-margined form of media was erroneous. This species 
is common over a great part of California and it is the form 
which has been distributed under the MS name of Lopidea 
obscura Uhler. Generally the clavus as well as the costa is 
pale. 
Lopidea nigridea Uhler. This large blackish species is abun- 
dant everywhere on the chaparral during May and June. 
Hadronema robusta Uhler. Abundant on the “white sage” 
during May and June, especially on the dry granite hillsides 
in the back country. 
Strongylocoris stygica Say. Common on sun-flowers grow- 
ing along the banks of small mountain streams at Mussey’s, 
Alpine and elsewhere from April to June. I have been un- 
able to detect the black legged atrata reported as common 
about Los Angeles by Dr. Uhler. 
Strongylocoris croceipes Uhler. Alpine, May and June, two 
examples. 
Macrotylus tristis Uhler. Lakeside, Foster and Mussey’s, 
April and May; not common. This species has a strong su- 
perficial resemblance to luniger as figured by Dr. Reuter 
but it seems to be sufficiently distinct. There is generally a 
pale spot on each of the callosities. 
Macrotylus regalis Uhler. My three specimens are much 
smaller than indicated by Dr. Uhler and differ in some 
other particulars, and I feel some doubt about the identifi- 
cation but they are all males while Uhler’s type specimen 
was a female and this with the difference in locality may 
account for the discrepancies. In my males the vertex has 
a red vitta reaching the base of the tylus, the entire prono- 
tum is red with three more or less distinct dusky vitte, the 
median invading the base of the scutellum, the costal mar- 
gin is black, widening a little to the cuneus; the membrane 
is smoky with the veins pale; legs testaceous-brown with the 
femora tipped with pale and the extreme base of the tibiz 
and the tarsi blackish; the rostrum is pale, the first joint 
beneath and the apex blackish; and the sides of the pleural 
pieces are red. These characters seem almost specific but 
it does not seem best at present to so consider them. All 
my specimens were beaten from chaparral in June. 
Macrotylus angularis Uhler. Three examples taken at San 
Diego on the white sage in April and May, 1913.
