LIMNJEA. 105 



22. LIMN^A HUMILIS, Saij. 



Hald., Monog., 41, t. 13, figs. 1, 2, 4, 5. 



L. Lecontii, Lea. Plate 18, fig. 4. 



L. Griffithiana, 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. 



Limncea 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.
