OF EASTERN PENNSYLVANIA, 89 



mature forms of Tabanus lineola, T. cinctiis, Tip- 

 ula ferruginea, Culex tczniorhynchus, among 

 diptera ; and Anisopteryx vernata, Clisiocampa 

 Americana, Spilosoma Virginica, S. acrcza, and 

 many of the Noctuidcz and Lyccznidce, in the con- 

 dition of imagos; besides coleoptera and minute 

 mollusks. 



The note of the Long-billed Marsh Wren is a 

 harsh, grating cry, lacking in power and harmony, 

 and resembling more nearly the sounds of an 

 insect than those of a bird. 



It is an early, autumnal migrant, usually retir- 

 ing to its winter quarters in the beginning of 

 September, long anterior to the growing scarcity 

 of food-stuffs. 



The eggs of this species range from six to nine 

 in number, are oval in shape, but occasionally 

 spheroidal. They are thickly marked with blotches 

 of a deep chocolate-brown, so as to present an 

 almost uniform appearance. The average length 

 is .65 of an inch, and breadth .50.
