before described by Degeer under another name. It is also L. 

 axilena Westw. Nat. Libr. 1, pi. 29, fig. 1.— Uhler.] 



9. L. QUADRUPLA. — Thorax with a whitish vitta ; abdomen 

 with a lateral, yellowish one ; wings with a bicolored stigma, and 

 basal blackish line. 



Inhabits Massachusetts. 



This insect very closelyr esembles L. Leda S. It differs, how- 

 ever, in being smaller, and in having the stigma larger, white, 

 with a black tip. The male is destitute of the black wing tips, 

 and like the female, has the exterior half of the costal margin 

 tinged slightly with ferruginous. The anal processes are short, 

 subcylindric, a little smaller at base, and beneath, towards the 

 tip, minutely denticulated ; at tip a small point. 



The sexes were sent me by Dr. Harris. 



Length from one inch and three-fifths to one inch and seveu- 

 tenths. 



10. L. BASALis. — Wings fuscous on the basal half. 

 Inhabits the United States. 



% Body brownish-black ; head immaculate, dark bluish ; wingB 

 dark fuliginous opaque, on the basal half, beyond which is a 

 broad, milk-white almost opaque band ; stigma blackish ; abdomen 

 somewhat depressed, of equal diameter nearly to the tip, dusky, 

 with a lateral dull yellowish vitta ; beneath black-brown. 



Length nearly two inches. 



[In a note attached to this description by Mr. Say, [24] is a 

 reference to L. marginata Degeer. Wings fuscous from the 

 base nearly to the middle. 



L. dimidiata Fabr. V. Enc. Meth., refers to Seba. which is 

 quite different. Said to be from Surinam, and is much smaller, 

 to which species the above described insect seems to bear some 

 resemblance in the arrangement of its colors. — Ed.] 



[Synonym is L. luctuosa Burm. Handb. 2, 861.— Uhler.] 



11. L. eponina. — Upper wings bifasciate and with a spot
