542 FAMILY VII. TETTIGONIID^E. THE KATYDIDS. 



T have, therefore, restored the name crythrocc]>liulu>n given to this 

 grasshopper by Davis. 



The known range of 0. erytTirocephalum extends from central 

 New Jersey southwest along the coast to southern Florida, Mo- 

 bile, Ala., and southern Mississippi, and inland to Raleigh, X. Car., 

 Macon, Ga., and Agricultural College, Miss. As will be noted by 

 the measurements it varies much in size, the northern specimens 

 being the smaller. It has been taken at various points in the 

 Pine Barrens of New Jersey and about Norfolk and Cape Henry, 

 Va. ])avis (1905) says that in life "its most noticeable feature is 

 a very red face, often the w r hole head being of a blood red color. 

 It appears as if the insect had eaten of ripe cranberries and got- 

 ten its head stained with the fruit, for the color is the same. 

 About Lakehurst it is far more common than 0. rulgarc." 1 



Fox (1914, r>2T) states that it is apparently restricted to 

 sphagnum bogs, where it frequents the dense growth of chain 

 fern, tall sedges, rushes and associated plants. Of its occurrence 

 about Cape Henry, Va., he says (1917) : "In addition to being- 

 common in the rank vegetation of dune hollows and ditches, it 

 was not infrequent in the tall bunch grasses on the surrounding 

 dry sand dunes. Farther inland it appeared to prefer areas of 

 stiff, but not always moist soil, occurring in the rank plant 

 growth of ditches, w T oodland borders and scrub. It evidently has 

 a strong predilection for sylvan surroundings." 



I have not taken erytTirocephalum in Florida but it has been 

 recorded from a number of localities as far south as Everglade, 

 being apparently more common in the northern third of the 

 State. There it occurs for the most part in wet grassy spots along 

 the edges of hammocks and in palmetto barrens. 



247. ORCHELIMTJM VULGARE Harris, 1841, 130. Common Meadow Grass- 

 hopper. 



Size medium, form robust. General color green or pale reddish-brown; 

 face pale green or light brown without fuscous marks; occiput and disk of 

 pronotum with a reddish-brown band, widening on the latter, where it is 

 often, especially in male, bordered each side with a darker line; male with 

 two short black dashes on each tegmen, the four forming the angles of an 

 assumed square, enclosing the tympanum; legs usually pale brown, tarsi 

 dusky. Pronotum long, its posterior lobe but slightly, if at all, upturned 

 above the plane of prozona; lateral lobes nearly as long as deep, the lower 

 hind angle obtusely rounded; convex callosity wide, prominent; humeral 

 sinus broad but well defined (Fig. ISO, c.) Tegmina reaching to or slightly 

 beyond tips of hind femora, and usually equalling, male, or very little short- 

 er, female, than wings. Hind femora rarely armed with one or two spines 

 beneath. Cerci of male as described in key, a little depressed; sub-basal
