PSYCHE. 



["November 1894. 



but tliree localities in New England, 

 but it probably occurs over the whole 

 of Connecticut and in central Massa- 

 chusetts. A nymph in Mr. Scudder's 

 collection is labeled "Vicinity of 

 Boston." 



My specimens are from Connecticut 

 as follows : — 



Canaan, Aug. i8, i ?. 



Thompson, July 13, 6 J , 3 ? , scarce. 

 " Aug. 4-9, 7 ? , very scarce. 



New Haven, Aug 29, abundant; males, 

 females and young in several stages, some 

 scarcely more than 2 mm. in length being 

 secured. 



The Thompson and Canaan speci- 

 mens were found on the sandy mud of a 

 lake-shore, and were yellowish-gray ; 

 the others on the margin of a little 

 stream strewn with fragments of lilack- 

 ened wood and other waste and were 

 very dark. 



I have taken it at Ithaca, N. Y., also, 

 where it is common along the stony 

 margins of the creeks and exactly 

 matches in tint the fragments of slate- 

 gray shale on which it delights to sun 

 itself, becoming inconsequence, almost 

 invisible on alighting. 



It is one of the most active and alert 

 of our species, taking wing readily and 

 flying several feet, or even a rod or 

 more. It is readil}' captured, however, 

 by sweeping the net rapidly over its 

 haunts.

The two New England members of 

 this genus are readily distinguished 

 from inir other Tettiginae by the 

 presence of twenty-two joints in the 

 antennae (instead of 13-14), •'"'' K^' ^^^^ 

 shape of the crown of the head, which 

 has a lobe on each side encroaching 

 u]5on the dorsal portion of the eve.
