32 PROCKE^DINGS MANCHES'TE^R INSTlTUTi:

Siib-Faiiiily Acridiiise. 



12 Scliistocera nibigiiiosa Harris.

14 Melaiiopliis atlaiiis Riley. 



15 Melaiiopliis feiiiur-riibrmii DeGeer. 



The unusually dry season of 1900 was most favorable to in- 

 crease of the locust tribe, and from a general observation of the 

 locality under consideration, the species appeared evenly distrib- 

 uted, though the Melanopli, Arphia xanthoptera, Spharagemon 

 collare, Dissosteira Carolina, Kncoptolophus sordidus and Cerco- 

 tettix verruculatus probably predominated. 



Stenobothrus, not so noticeable to the casual observer as the 

 bright- winged locusts, was present in good numbers, some very 

 good examples of both long and short wings being taken. 



Upon examination of a larger number of specimens and by aid 

 of additional descriptive material, I believe Stenobothrus macu- 

 lipennis should be cancelled from our list heretofore published 

 and Orphulellaspeciosa inserted in its place. * Individuals taken 

 the previous year had a tendency to follow S. maculipennis in 

 coloration and wing length, but those more recently collected 

 have taken on all the varying hues of green, purple and brown 

 to which they are entitled and a correspondingly wide range in 

 length of wings. 



The Arphias of Rock Rimmon are rich and finely marked in col- 

 or which together with their substantial size make them most al- 

 luring to the collector. 



The species that I have designated as Spharagemon collare, 

 I take to be the New England form of Say's Gryllus sequalis or, 

 as I previously listed, Dissosteira aequalis.. 



Thomas Say's original description of this species was read 

 June I, 1824, in the list of "new Hemipterous insects collected 

 in the Expedition to the Rocky Mountains performed by order 

 of Mr. Calhoun, Secretary of War, under the command of Ma- 

 jor Eong."
