40 NORTH AMERICAN ACRIDIID^E. 



Eotettix palusttis Morse. 



Eotettix palustris. Psyche, XI, 7 (1904)- 



"Intermediate in size and appearance between signatus and 

 pusillus. Facial costa widest opposite base of antennae, equalling 

 interspace between eyes, with convex sides convergent above and 

 below, subparallel in lowest portion. Tegmina broadly oval with 

 rounded apex, shorter than pronotum. Abdomen of male less up- 

 turned at tip than in pusillus; furcula well-developed, flattened or 

 digitate; supra-anal plate triangular, its breadth nearly or quite 

 equaling its length, the apex rounded, acute. Cerci conical, 

 slender, tapering evenly, about three times as long as their basal 

 width. 



" Color light yellowish green, brown above and on tegmina, 

 with fuscous post-ocular stripes from eyes to tegmina. Hind tibiae 

 red with black spines. This species and signatus agree in lacking 

 the fuscous markings on the abdomen characteristic of pusillus, and 

 in possessing red hind tibiae. In signatus the apex of the supra- 

 anal plate is usually very bluntly rounded, and the tegmina are as 

 long or longer than the pronotum, broad lanceolate, with acute apex. 



"Length of body : male, 15-15.5 ; female, 21.5 ; hind femora : 

 male, 10 ; female, 14; antenna: male, 8 ; female, 9; tegmina: 

 male, 2X3.5 to 2.8X4 ; female, 3.5X5 mm." 

 Florida : Live Oak, Aug. 10. 



Lower Austral. This agile little species was found in the 

 scrubby undergrowth of palmettoes and bushes in the damper spots 

 of the piney woods. 



Eotettix pusillus Morse. 



Eotettix pusillus. Psyche, XI, 7 (1904). 



"A diminutive species readily distinguished from signatus by 

 its size and nearly circular tegmina. Facial costa widest between 

 antennae, nearly equalling interspace between eyes, with parallel 

 sides, abruptly narrowed below the median ocellus to two-thirds of 

 its width above. Disk of pronotum tectiform, distinctly convex in 

 longisection, the mid-carina very pronounced, the lateral carinae 

 faintly indicated on the prozone, obsolete on metazone. Tegmina 

 broadly obovate or sub-circular, two-thirds or three-fourths as long 

 as the pronotum. Tip of male abdomen upturned, supra-anal plate 

 triangular, nearly or quite as broad as long, pointed at apex, with 

 sinuous sides. Furcula well developed, consisting of two broad 

 flattened lobes as long as or longer than the last dorsal segment. 

 Cerci subconic, shorter than supra-anal plate, two to three times
