SUBFAMILY III. LOCUSTINJE. 397 



basal third strongly silicate with the margins of the sulcations carinate. 

 Cerci as described in key, the margins feebly convergent to the narrowly 

 rounded apex. Subgenital plate small, convex, tapering to the very narrow 

 and produced rounded apex which is without a trace of the subapical tu- 

 bercle found in the species of Eotettix. Valves of ovipositor moderately 

 elongate, not strongly curved distad to their acute apices. Length of

This locust was taken by R. & H. at DeFuniak Springs and 

 Pensacola, Fla., Aug. 28 30. At the former place "it was found 

 in sandv long-leaf pine woods, with undergrowth of wire-grass 

 and many oak shoots and dwarf oak. Wherever this type of conn- 

 try occurred the insect was found in large numbers, the oak under- 

 growth evidently being the food plant. The species is truly tham- 

 nophilus, not rapid in its movements, but jumping with great 

 I >ower. When approached, individuals often hid on the under 

 side of the oak leaves and when seized by a sudden grasp were 

 found to cling tenaciously to their support." (Hebard.} At 

 Pensacola it was very rare among gallberry bushes, Ilex glaltra L., 

 in low, sandy pine woods. 



185a. MELANOPLUS DAVISI QUERCICOLA (Hebard), 1918, 156. Oak-loving 

 Locust. 



"Agrees in all respects with davisi except in the following features: 

 Size somewhat smaller, form less, attenuate. Tegmina slightly overlap- 

 ping, oval, the curvature of the margin greatest distad, surface showing no 

 definition between dorsal and lateral fields. Prosternal spine stouter, 

 that of female somewhat flattened in front and behind. Supra-anal plate 

 as in davisi except that a transverse carina runs for a short distance laterad 

 from the extremities of the carina? bounding the proximal median sulcus. 

 Cercus slightly over twice as long as proximal width, dorsal margin very 

 feebly concave to apex, ventral margin feebly convex and converging to- 

 ward dorsal margin in proximal three-fourths; the remaining narrow dis- 

 tal fourth of the cercus curved inward with margins parallel to the rounded 

 apex, this portion about one-third as wide as the basal width (Pig. 136, e.} 

 Subgenital plate with apex decidedly broader, feebly bilobate. Length of

The above includes all the essential parts of the original de- 

 scription. The locust was taken by R. & H. at Woodville, Carra- 

 belle and Ocala, Fla., Sept. 110. Of its habits Hebard (1018, 

 1H8) says: "The species was found common in sandy long-leaf 

 pine, Finns pal list rift Mill, flatwoods among dwarf oak and oak 

 shoots at Woodville; very few in scrub oak and oak shoots on flat
