156 NEW NORTH AMERICAN MELANOPLI (oRTHOPTERA) 



The species was found very rare in gallberry bushes, Ilex 

 glabra, in low sandy long-leaf pine woods, Pinus palustris, at 

 Pensacola. At De Funiak Springs in sandy long-leaf pine woods, 

 with undergrowth of wire-grass and much oak shoots and dwarf 

 oak, the insect was found in large numbers, locally wherever 

 this type of country occurred, the oak undergrowth evidently 

 being the food plant as was also found to be true for the aUied 

 quercicola. The species is truly thamnophilous, not rapid in its 

 movements, but jumping with great power. When approached, 

 individuals often hid on the underside of the oak leaves and 

 when seized by a cautious approach and sudden grasp were 

 found to cling tenaciously to their support. 

 Eotettix quercicola new species (Plate VIII, fig. 14.) 



This species agrees closely with E. davisi, here described, in 

 both general appearance, habits and actions. The present insect 

 supplants davisi in Florida east of De Funiak Springs. 



This species is readily distinguished from davisi in the male 

 sex by the very different cerci and appreciably broader apex of 

 the subgenital plate, and in both sexes by the tegmina, which 

 show no distal truncation and have their surfaces even, showing 

 no definition between the dorsal and lateral fields. The males of 

 this species also average distinctly less attenuate, while the 

 females show the post ocular dark bars in their maximum intensi- 

 fication narrower than is normal in davisi, with coloration of the 

 same solid and ventral margins not irregular. 



Type. — c^ ; Woodville, Leon County, Florida. September 1, 

 1915. (Rehn and Hebard.) [Hebard Collection, Type No. 479.] 



Agrees in all respects with the type of davisi, except in the following features. 

 Size moderately large (average somewhat smaller than in davisi) ; form medium, 

 not as attenuate as in that specie?. Pronotum with medio-longitudinal carina 

 not fully as decided as in davisi. Tegmina slightly overlapping, oval, the 

 curvature of the margin greatest distad, surface showing no definition between 

 dorsal and lateral fields. Supra-anal plate as in davisi except that a transverse 

 carina runs for a brief distance laterad from the extremities of the carinae, 

 bounding the proximal median sulcus. Cercus slightly over twice as long as 

 proximal width, dorsal margin very feeblj^ concave to apex, ventral margin 

 feebly convex and converging toward dorsal margin in proximal three-quarters, 

 the remaining narrow distal fourth of the cercus curved inward, with margins 

 parallel to the rounded apex, this portion about one-third as wide as the basal 

 width. Subgenital plate as in davisi except that it is somewhat more produced,
