HEMIPTERA. VAN DUZEE. 29 
Macrotylus vestitus Uhler. Lakeside and Alpine, May and 
June. 
Oncotylus repertus Uhler. Mussey’s, one example taken in 
April, 1914, from weeds growing along a stream. 
Oncotylus punetipes Reut. La Jolla and Alpine. Taken on 
wild honeysuckle. These are a little larger than my eastern 
specimens but do not seem to differ otherwise. 
Lopus decolor Fallen. Alpine, May; one example. 
Psallus anchorifer Fieb. San Diego and Alpine, April to 
June. 
? Psallus breviceps Reut. If I have rightly identified this 
species with material taken here it is perhaps our most 
abundant and widely distributed Capsid in this part of the 
state. The males are rather slender and mostly dark, with 
the legs somewhat paler and a broad white arc on the base 
of the cuneus. The female is more ovate with the elytra 
paler at base as noted by Reuter and this coloring is some- 
times found in immature males. The antennz are mostly 
blackish in both sexes. Dr. Reuter evidently had two pale 
females before him when describing the species. 
Criocoris saliens Reut. I have found this species abundant 
on a species of Galium growing on the dry hillsides at 
Mussey’s, Alpine, etc., from April to June. It most certain- 
ly belongs to genus Criocoris. The form and color of the 
second antennal joint of the female on which Dr. Reuter 
founded his genus Strongylotes is entirely inappreciable. 
This species is very close to my canadensis but it is little 
narrower, the second joint of the male antennz is broader 
and more flattened and narrowed toward the apex, the 
extreme base of this joint in the female is concolorous and 
not black as in my eastern species and the membrane wants 
the pale markings found there. 
Plagiognathus verticalis Uhler. I took this species in great 
numbers at Ocean Beach in May, 1913, and have found it 
common elsewhere during April and May. Uhler’s descrip- 
tion is very inadequate but I believe I have rightly deter- 
mined the species. Dr. Reuter’s keys for separating this 
genus from Psallus are unsatisfactory. Comparing speci- 
mens determined by Dr. Reuter himself I find the eyes are 
not more granulated nor the last tarsal joint longer in 
Psallus. 
Plagiognathus decolor Uhler. San Diego and Lakeside ; April 
and May. I am much inclined to think that this species 
would better be left in Agalliastes (Chlamydatus ) where Dr. 
Uhler placed it. 
Atomoscelis seriatus Reut. This pretty little species seems 
to be abundant at many places from San Diego to Alpine 
from April to September.
