This species is known only from a few stations in Georgia. 

 Scudder's types were from that State without definite locality. 

 He at one time (1880, 75) expressed the opinion that clypcatus 

 was the long-winged form of his J/. nigrescens, but evidently 

 changed his views as he redescribed both under different series 

 in his "Revision.'' B. & H. (1910, 245) have recorded clypeatus 

 from Thomasville and Sandfly, Ga. At the latter place it was 

 "found to be very scarce in the heaviest undergrowth in gray- 

 bark pine woods, in more or less swampy situations." 



206a. MELANOPLUS CLYPEATUS SYMMETBICUS Morse, 1904, 8. Symmetrical 

 Locust. 



Very close to M. clypeatus. Color much the same, the discoidal field 

 without spots and only slightly darker than the costal one. Inner face of 

 hind femora coral red on basal two-thirds and with three oblique fuscous 

 bars. Lateral lobes of pronotum shorter and deeper in the female than in 

 that sex of clypeatus. Apex of subgenital plate less elevated than in cly- 

 peatus, its tip without a tubercle. Other differences as given in key.

Known only from Florida. Morse's types, which I have exam- 

 ined, were taken at Carrabelle, August 9. He states that they 

 were secured in a grassy swamp not far from the beach and 

 were associated with Paro.ri/a cttlatitictt and clai'uliyer and Sehis^ 

 toccrca alntacca. It is a campestral species resembling fcmoratus 

 in size, appearance and haunts, save for some minor differences 

 in coloring. Some of the specimens in the Philadelphia collec- 

 tions taken at Tensacola, Aug. 28, have the upper lobe of cerci 

 more prolonged than in the ones from Carrabelle, approaching 

 those of cl >/ pea tu ft, of which I regard it as only a variety. 



207. MELAXOPLUS FURCATUS Scudder, 1917b, 30. Fork-tailed Locust. 



Size very large, form robust. Brownish-ferruginous, the top of head 

 and prozona faintly clotted with fuscous. Tegmina colored as described in 

 key. Hind femora with inner face twice barred with black, which some- 

 times shows feebly above and on outer face where it is diffused; lower 

 face dull red. Hind tibia? as in clypeatus. Interocular space broad, but 

 distinctly narrower than frontal costa; fastigium very feebly depressed, 

 running without break into the frontal costa which is broad, equal, shal- 

 lowly sulcate at and below the ocellus. Pronotum as described under the 

 series heading, its median carina very low, distinct only on metazona; 

 prozona about a fourth longer than the finely and closely punctate meta- 

 zona. Supra-anal plate with a deep basal median sulcus reaching beyond
