Psyche 
[December 
Eurema euterpe (M£n£tries). 
Manchester : Field west of Proctor street, September 4, 1924, 
two (A. B. J. C.). Blossom Lane, September 5, 1924, two (A. B. 
J. C.). 
Essex: Bog off Conomo street, August 10, 1924, one fresh 
male (A. B. J. C.); July 30, 1925, one fresh male (A. B. J. C.). 
Ipswich: about a quarter of a mile east of the lighthouse, 
August 25, 1925, one fresh female (A. H. C.). 
This insect is probably less infrequent in Essex county than 
the records would seem to indicate as it is very easily confused 
with Eurymus philodice. In calm weather it is readily distin- 
guished by its slower, feebler, lower, and more tortuous flight, 
but if there is any wind the differences tend to vanish. Although 
I am very familiar with this species I mistook the one captured 
at Ipswich for its larger and more powerful relative until it 
alighted on a beach pea immediately in front of me. 
SOME RARITIES FROM ESSEX COUNTY, MASS. 
By A. P. Morse. 
Peabody Museum, Salem, Mass. 
Several years ago I recorded (Psyche, vol. 28, p. 7,-1921) 
the capture of three examples of a dragonfly, Sympetrum corrup- 
um, rare in Massachusetts, at Plum Island, Ipswich, Sept. 10, 
1911. 
On July 11, 1924, it was a common and conspicuous insect at 
a small pond in Marblehead, a dozen or more individuals being 
seen, of which four males and a female were secured. 
Another rarity in eastern Massachusetts, the butterfly Chry- 
sophanus thoe, believed to be the first example recorded from the 
county, was taken Sept. 6, 1924, at Salisbury, Mass. 1 This was 
a female in perfect condition, and was found on goldenrod flowers 
at the edge of the saltmarsh. A male also was seen but not 
secured.
