LIMN ZA. 105 
22. LIMNEA HUMILIS, Say. 
Hald., Monog., 41, t. 18, figs. 1, 2, 4, 5. 
LL. Lecontii, Lea. Plate 18, fig. 4. 
L. Grifithiana, Lea. Plate 18, fig. 5. 
This species is abundantly distributed from 
Vermont to South Carolina and Georgia, and 
westward to California. The illustrations of 
Haldeman are rather unfortunate, representing 
extreme rather than the typical forms. For 
the latter, my figure of L. Griffithiana will 
answer very well. 
Iamnea modicella, Say, included by Halde- 
man and Binney in the synonymy of this 
species, is synonymous with L. desidiosa, as I 
have convinced myself by a critical study of 
type specimens preserved in the Philadelphia 
Academy.
