MORSE: ORTHOPTERA OF NEW ENGLAND. 433 
extremely rare; brown males are not common, usually less than 
half as plentiful as brown females, but the proportion of indi- 
viduals of the two colors varies much locally, and, it is believed, 
according to the prevailing color of the environment. 
The Bicolored Locust is a common species in southern New 
England in the latter part of the season, adults appearing in the 
latter half of July and lingering until late in October, having 
been recorded on the 23d of that month in Connecticut. It is 
most common in rich pastures and old mowing-lands on heavy 
soil, and delights especially in moist places such as are found in 
damp meadows and the vicinity of springs, brooks, and ponds, 
where the grass is dense and luxuriant throughout the season. 
This is perhaps the reason for the more generally prevalent green 
color, which renders it inconspicuous. Well protected by its 
coloration, it is a sluggish creature, and rarely uses its wings 
even when these are fully developed. 
This Locust probably inhabits all quarters of Connecticut and 
Rhode Island, much of southern and central Massachusetts, and 
possibly reaches New Hampshire and Vermont in the Con- 
necticut valley. At the time of publication of my "Notes" 
(1896) and article on the distribution of New England Locusts 
(1899) I had not found this species in the vicinity of Boston. In 
recent years, however, it has been captured in small numbers at 
several points in this district, viz., Sherborn, Wellesley, Needham, 
and Sharon, Mass., but it is much less abundant here, even 
locally, than in Connecticut and farther south. Whether its 
appearance in this vicinity is due to recent invasion from the 
southwest, a possibility which I suggested in one of the papers 
cited, remains to be proved. If so, it will probably increase in 
numbers, become more generally distributed here, and continue 
to extend its range toward the northeast. 
THE NEW ENGLAND SPECIES OF ORPHULELLA. 
Our species of this genus resemble each other closely and for a 
long time two of them were not only generally confused but 
received several additional names applied chiefly to color varia- 
tions. Critical study has since reduced these to synonyms. The 
third species, which is found only in salt-marshes in extreme 
southern New England, escaped notice until I had the good for-
