uniformly destructive, is Melannplus atlanis. The wings 

 are long and the capacity for flight more like Melannplvs 

 spretus, but flight seldom reaches more than a few miles. 



The Beach Locust {Trimerotrojjis maritima). — The beach 

 locust is an interesting species that occurs along the coast 

 of the ocean as well as fresh-water lakes or where sand dunes 

 are common. The coloration and markings are very dis- 

 tinctly adapted for protection and the nymphs are really 

 about as well protected as the adults. They are conspicuous 

 on the wing, part of the wing being bright yellow in color, 

 but when they alight on the sand they immediately disap- 

 pear on account of the color and markings. They must 

 feed on grasses in such locations and are often found around 

 clumps of Juncus and Arenaria, but rarely seen feeding.

This species is found in June and July in the larval and 

 nymphal stages, and in different sizes, some comparatively 

 small, representing the second and third moult. Their 

 moults occur fairly rapidly during this particular time. 

 There is some difterence in the time of hatching from eggs, 

 and adults are to be found by the early part of July. The 

 time varies in different seasons. Later in summer there will 

 be very few larvse and a large number of adults, and still 

 later only adults. The adults remain active and travel 

 over the sand for several weeks. They make characteristic 

 tracks on the sand, easily detected. They probably do not
