Chelinidea vittiger subspecies equoris n. subsp. 
In its most pronounced phase this subspecies is ohesister ced 
by very low pronotal margins, especially along the sides anteriorly, 
which in some specimens are scarcely carinate (that is almost 
smoothly rounded over). The postocular tubercle in all is very 
small, in some entirely lacking. The color of typical specimens 
is the palest of any Chelinidea examined, being with the excep- 
tions of the greenish black membrane and reddish eyes, entirely 
stramineous to sordid buff. 
The name proposed for the subspecies, derived from a word 
applied by the Romans to smooth bodies of water and by license 
to areas of level ground, is considered appropriate for a form 
which seems to be restricted to the Atlantic Coastal Plain the 
best marked biotic area of Eastern North America.

A form of subspecies equoris with the legs and antennz nearly 
or entirely black, with darker corium and dark bar across pos- 
terior part of pronotum, may be known as variety artuatra, new 
variety. This form contains the variants toward subspecies 
vittiger.
