Tuckerton and Cape May, N. Jer., Aug. 21 Sept. 1 (Dads) ; 

 Ocean View, N. Jer. (Foap) . A subrnaritime species described from 

 a single female taken at Cedar Keys, Fla., but not elsewhere re- 

 corded from that State. Ranges from New Jersey along the At- 

 lantic coast to Virginia and probably to Florida. Davis 

 (1913, 177) took the first known male Sept. 1, 1907. at Tuckerton, 

 N. Jer. R. & H. (1915, 378) give an account of the habits of 

 melanorhinus as follows: 



"This species was found in large numbers on the salt marsh tidal 

 flats of New Jersey in areas of the salt meadow-grass, Spartina patens 

 (Ait.), growing near one foot in height, but it was also found there rather 

 abundant in areas of the low marsh spike-grass, Distichlis spicata (L.). 

 When first met with in the summer of 1914, the males of a large colony 

 were stridulating vigorously early on a somewhat cloudy afternoon; the 

 song was a weak, high-pitched continuous buzzing, giving much the same 

 vibrating resonance as a bit of rubber stretched in the wind. The note 

 was very much weaker, richer in quality and less harsh than that of N. 

 robustus. During daylight the singers invariably seemed further away 

 than was the case, and time and again specimens were passed over until 

 this fact was realized. At night the song was somewhat louder and 

 very similar to that of N. lyristes, almost inappreciably higher pitched 

 and more strident. When an individual was alarmed while singing the 

 note ceased abruptly, the singer dropping or leaping to the ground and 

 there remaining motionless, perfectly concealed. * * * The abundant 

 green color-phase of this insect blends perfectly with the broader green 

 leaves of Spartina patens, while the brown individuals of pale to very dark 

 shades blend as perfectly with the brown and yellowish bases of the same 

 plant and the bare dark muck beneath. The insects were seen to fly but 

 short distances while singing individuals were observed to be resting mo- 

 tionless on the grass or climbing nervously about." 



237. NEOCONOCEPHALUS ENSIGEB (Harris), 1841, 131. The Sword-bearer. 

 A species of small size and slender form. Green, rarely brown, often 

 fading to dull yellow in drying; margins and tip of lower face of fastigium 

 black, the tooth green; lateral carinas of pronotum often yellow; tarsi, 

 hind tibia? and tip of ovipositor sometimes darker. Fastigium slender, 

 slightly constricted in front of eyes, narrowed from the middle forward 

 (Fig. 169, e.) Pronotum with lateral carina^ feebly divergent, disk finely 

 punctate; humeral sinus shallow, very broadly rounded. Tegmina long 

 and narrow. Stridulating vein of male long, feebly swollen (Fig. 170, c.) 

 Front and middle femora usually unarmed. Length of body, $ , 24 26,
