200 FAMILY VI. ACRIDIDJE. THE LOCUSTS. 



it in the tribe Hcsopcs, which, in his Catalogue, is located near 

 the beginning of the Acridinae (Locustinse). While the proster- 

 nuiu bears a tubercle, it is very short and obtuse, and the other 

 characters are so decidedly those of the Tryxalinse that I have no 

 hesitancy in so placing it. But one species is known.

Sherborn, Mass., July 15 (Morse] ; Gardiner's Island, X. Y., 

 Aug. 23 (Danx). Of its habits Morse has written (1896, 382) as 

 follows: "This peculiar locust is not uncommon locally on the 

 coarser grasses found in waste lands, especially upon a species of 

 bunch-grass (Andropogon scoparius Michx.) everywhere abun- 

 dant. Though a good leaper and fairly active, it is not shy and 

 seeks safety in attempting to escape observation by sidling around 

 the grass stems rather than by active retreat. I once saw a long- 

 winged female fly several feet, proving that with the possession 

 of the means came the power of flying. Its sluggish habits, how- 

 ever, in connection with its linear form, render it less likely to 

 attract the attention of its enemies, and to the biologist it is per- 

 haps the most interesting of our New England locusts on that 

 account. It must be seen in the living state to have its full beauty 

 appreciated. The singular, almost grotesque, yet graceful form 

 interests even the casual observer, and its coloration of lilaceous
