The moth at rest sits pressed flat to its support, second joint of 

 hibial palpi and sides and ends of wings closely applied to it. 



The insect seems to be quite common where it is found, and one 

 palm leaf ma^^ contain several cases. 



The genus is given the character '"7 and 8 in forewing connate or 

 stalked," so as to include the common palmetto feeder {Lavema) 

 sahalcUa Chambers, which naturallv belongs here, and which has a 

 similar, although not so specialized, habit as heptaihalmna. Sabalella 

 has all the characters of the genus and di tiers only from the tj'pe in 

 veins 7 and 8 being stalked, instead of connate. As it is a less special- 

 ized and a smaller insect the characters are less pronounced, and I 

 therefore make the larger form the type of the genus.

 Cocoon is chestnut brown, 1.6 by 1 mm. 



Of the described American species it comes nearest A\ apiclalhella 

 Chambers, the description of which ver}^ nearly agrees with this spe- 

 cies. Chambers's measurement, /^ inch, and his type specimen in 

 U. S. National Museum, shows, however, that (ipickdhdla is a larger 

 species which has relativeh^ broader wings and broader fascia.
