drying up of tJic treetops of i)ines which arc overrun l)y cpian- 
tilies of these insects, wliich keep mostly under the loose ])ieces 
of hark on the upi)er part of the stem.” (Translation from 
the Russian by ])r. .A. Petiaiidvoviteh.) The species exhibits 
l)ut little variation in the eastern states, l)ut in the west a form 
has developed which seems to deserve subspecific rank. 
Aradus (Aradus) cinnamomeus suh.spccie.s antennalis .subsp. nov. 
Description . — iSiinilar to the ty])i(*al form except as follows: Antennae 
(lark brown, the third segment brif^ht yellow in apical half. Ileinielytra 
in brachypterous female extending almost or (pute to middle of third ab- 
dominal segment, and provided with a narrow but distinct membrane along 
the oblique ai)ical margin of the corium.

fornia, ATI, 18, 1885; in my collection. Clen, Sioux County,

This is a western torm which cannot ])e separated sitecifically, 
but it is rather well distinguished l)y the charactei's given. Speci- 
mens taken in the eastern states lack the membrane, hardly a 
trace ever l)eing noticeable, but European examples sometimes 
have it as well developed as in the western race. AAdth the 
single exception of a specimen from northwestern Nebraska all 
material referable to antennalis which I have seen has l)een col- 
lected in the Pacific region. In California the typical form also 
occurs.
