nearly all have matured by the latter part of July. They occur 

 most abundantly on the sand adjacent to the clumps of grass upon 

 which they doubtless feed, though so far no individuals have been 

 observed actually feeding on grass leaves, but one was observed 

 eating a fragment of apple cast up in drift materials on the beach. 

 When disturbed they invariably alight on the sand, upon which 

 they become at once invisible. About the only way to capture them 

 is to throw a net down on a spot wliere one has been seen to alight, 

 and then it not infrequently happens that two or even three will be 

 caught though their presence lias not been suspected. 



The adult is whitish gray speckled with ferruginous fuscous and 

 blacl^, conspicuous ferruginous points occurring usually on the 

 anterior inargin of pronotum and on tlie lower borders of epimera of 

 meso- and meta-tliorax, humeri of elytra and discal carina of femur, 

 these may be faint or obsolete, and on wings and legs may form 

 slender lides; dark freckles occur on carinse of vertex and face, 

 forming a series back of collar on pronotum, on posterior border of 

 pronotum and on sides of elytra and hind femora; on elytra they 

 are thicker at three places, one-fourtli, one-half and two-thirds from 

 base, constituting fairly distinct patches, and on femur are two 

 indistinct bands corresponding with well marked black bands on the 

 inner side. Anterior and middle femora and tibiae nearly wliite, 

 milky, with gray annulations; hind tibite gray at base, distal two- 

 thirds yellow, in one form orange or reddish, spines yellow, tipped 

 with black, anterior and middle tarsi ferruginous or reddish, hind 

 tarsi yellow. The sternum is finely pilose. A variety is quite 

 uniformly yellowish gray. 



The larvae are similarly speckled but differ in that the dorsum 

 of abdomen is densely speckled, while in adults this part protected 

 by the folded wings is not speckled. In all these points a perfect 

 adaptation to the color and markings that blend with the sand grains 

 is evident. 



In the latter part of the summer of 1899, many of these grass- 

 hoppers died from an attack of parasitic fungus, and in such cases 

 climbed up on stems of grass where their whitened bodies became 

 very conspicuous. Eggs are doubtless laid in autumn probably in 

 packed sand in grass clumps to hatch in following spring. 



NOTES ON THE BIRD LIFE OF CEDAR POINT. 

 Robert F. Griggs. 



Ecologically Cedar Point is an exceedingly interesting region. 

 It is a narrow peninsula on one side of which flourishes a xerophytic 

 dune flora, and on the other a luxuriant hydrophytic marsh flora. 

 The meeting of these two gives the flora a very peculiar aspect.
