The above description is the original one of qucrcipcrda by Fitch.

ADDENDA 



Whilst the above work was in press we received two specimens 

 which in our opinion are worthy of a name ; they probably represent a 

 local form of G. arbcloidcs Dyar. We characterize it as follows : 



G. ARBELOIDES RUFESCENS U. var. 



Similar in maculation to arbeloides Dyar, the scaling of both primaries and 

 secondaries is, however, a bright red-brown, giving the insect a general rufous 

 appearance, lacking in arbeloides. which has purplish-brown patches on a gray- 

 brown ground. Thorax and abdomen unicolorous with primaries. 



Habitat., Greenville, Miss, i 3 i 9 Types Coll. Barnes.
