576 FAMILY VII. TETTIGONIIDJE. THE KATYDIDS. 



The known range of the species extends from the type locality 

 to Raleigh, N. Car., along the middle Atlantic coastal plain where 

 it inhabits the luxuriant grasses growing about the borders of 

 marshes near both fresh and brackish water. In Virginia Fox 

 (1917) found it "Occasional in tidal marshes, especially in the 

 tall reeds, Spartina cynosuroides (L.) upon the spikelets of 

 which it was observed feeding. It was apparently active only 

 at night." 



267. CONOCEPHALUS AiGiAXus Rehn & Hebard, 1915b, 202. Sea Shore 

 Meadow Grasshopper. 



Size medium; form robust, compact. Pale green; occiput and disk of 

 pronotum with a broad pale brown stripe. Tegmina pale translucent 

 brownish-yellow; apical half of male abdomen (in life) bright yellow, fad- 

 ing to dull clay-yellow; hind knees and all the tibiae tinged with fuscous. 

 Fastigium slightly ascending, its sides almost parallel. Eyes very large 

 and prominent. Lateral lobes with front and lower margins merged, with- 

 out evident angle; lower hind angle narrowly rounded; humeral sinus very 

 shallow. Tegmina of delicate structure, usually abbreviate and covering 

 three-fourths of abdomen, male, two-thirds, female, their tips obliquely 

 sharply rounded; in macropterous form, surpassing hind femora 3 mm., ex- 

 ceeded by wings 4 mm. Hind femora armed beneath on outer margin with 

 one to seven spines. Cerci as in key and Fig. 188, I. Length of body,

South Jacksonville, Fla., Sept. 7 (Dads}. The types were 

 from Wrightsville, N. Car., and the known range of the species 

 extends from Cape Henry, Va., to Pablo Beach, Fla. Accord- 

 ing to K. & H. (1915b, 203) it "inhabits salt marsh vegetation 

 on the beaches and along the tidal rivers of the Atlantic coast 

 where its habits are very similar to those of C. sjxirtimr (Fox) ; in 

 the present case, however, the insect is found not out on the 

 marshes, but in the halophytic vegetation along their borders and 

 iu similar vegetation on the beaches." 



268. CONOCEPHALUS NIGROPLEURUS (Bruner), 1891, 58. Black-sided 

 Meadow Grasshopper. 



Size medium; form robust. Dimorphic in color; either with tegmina. 

 legs, margins of lateral lobes and metazona bright grass-green or with these 

 parts brownish-yellow, the green wholly absent; both forms with stripe on 

 occiput and sides of abdomen shining black, the former narrowing in 

 front to the width of fastigium and bordered each side with yellowish- 

 white; the usual brown stripe on disk of pronotum but faintly defined in 

 green form, in the brown one very evident; face and median areas of lat- 

 eral lobes dark brown. Fastigium feebly ascending, its sides slightly di-
