HEMIPTERA. VAN DUZEE. 47 
258. Okanagana blaisdelli Uhler. There are two quite distinct 
forms taken here which have evidently been confused by Dr. 
Uhler in drawing up his description. I have one specimen 
which I believe represents the true blaisdelli as it agrees 
with Uhler’s description in being “long, narrow and paral- 
lel sided.” It also agrees in the remarkably heavy elytral 
venation and in most of its other characters. It disagrees 
in the form of the last ventral segment which is here quite 
regularly narrowed to a scarcely emarginate narrow apex 
and in having the yellowish color less extended on the head 
and pronotum. The size given by Dr. Uhler covers both of 
these forms so it has little value; my specimen corresponds 
almost exactly with his smallest dimensions. My single 
male specimen was taken at Alpine, June 20th, 1813, from 
the chaparral. 
259. Okanagana dstanti n. sp. 
This species is much broader and stouter than the form de- 
termined above as blaisdelli, being fully as broad as rimosa and 
vanduzei. It differs from blaisdelli as restricted above, aside from 
its form, in having the sides of the pronotum anteriorly more 
rounded and scarcely if at all crenulated and in having the opercles 
regularly rounded at apex or at most very obscurely sinuated. 
The elytral nervures while heavy are much less so than in blaisdelli 
and are mostly pale. The pale colors of the whole insect are more 
extended and the posterior pair of pale spots on the disk of the 
mesonotum are larger posteriorly and enclose a black point. 
This is evidently a still plastic species of which I have taken 
three forms or varieties here. What I call the typical form is 
Common on the high pueblo lands between La Jolla and Torrey 
Pines during late May and early June. It is larger measuring 25 
mm. to the tip of the abdomen and 33 to the apex of the elytra with 
a pronotal width of 11 mm. making it the broadest of our species. 
Here the sides of the pronotum while deeply sinuated are little 
expanded anteriorly, the last ventral segment is long and regularly 
narrowed to the rounded apex and the nervures of the elytra are 
pale before the nodus, excepting only the first ulnar. 
Another form which I propose to call (260) var. truncatus oe- 
curs in numbers about the city of San Diego during June. It has 
the last ventral segment broad and truncated at apex which is 
more or less inclined to be sinuated, sometimes strongly so, the 
Sides of the pronotum are more deeply sinuated and strongly ex- 
panded anteriorly, and the second ulnar nervure only is black, in 
whole or in part, before the nodus. It is smaller than distanti. 
A third form which I propose to call (261) var. pallidus is still 
Smaller measuring but 22 mm. to the tip of the abdomen and 30 to 
the apex of the elytra. It has the last ventral segment long and 
truncated but not at all sinuated at apex, the sides of the pronotum 
are but little sinuated and not at all expanded anteriorly, and the 
colors are much paler, the yellowish markings being much extend- 
ed, especially on the pronotum where they cover a large part of the
