The differences are slight, however, and the present writer 
-would range this form and the new one indicated below as sub- 
species of a single transcontinental species. These three sub- 
species may be separated as follows: 
A. Beak reaching past middle coxe................. subspecies typheus. 
AA. Beak not or barely attaining middle coxe. 
B. Length of terminal antennal joint 5.3 to 7.25 times its di-

Color in all three forms is extremely variable, and apparently 
must be disregarded in classification. 
As type of the new subspecies, a specimen from Thies Angeles 
Co., Calif., collected by D. W. Coquillett, is selected. This speci- 
men is figured in The Insect Book, L. O. Howard, 1904, PI. 29, 
fig. 13, and is deposited in the National Museum. 
Specimens of Merocoris typheus curtatus examined came from 
the states of California, Arizona, New Mexico, Colorado and 
Mexcac: 
Specimens of Merocoris typheus distinctus have been seen 
from New York, New Jersey, Maryland, Virginia, Alabama, 
Illinois, lowa, Missouri, Arkansas, Kansas and Oklahoma. 
Specimens of Merocoristypheus typheus have thus far been 
seen only from Florida.

SEPARATION OF JuG# IN Dendrocoris humeralis. 
In Mr. H. G. Barber’s key to Dendrocoris,* D. humeralis is 
placed in the section with “head rounded in front, with lateral 
lobes more or less in contact.” It is worth noting that some 
specimens collected in the vicinity of Washington, D. C., which 
agree in other respects with D. humeralis have the juge dis- 
tinctly separated in front of tylus. :
