MORGAN HEBARD 159 



Pratensis Group, of which osceola is the only member having 

 greatly reduced tegmina and wings. 



Compared with H. brevipennis (Thomas) the present insect is 

 seen to average smaller and more slender, the medio-longitudinal 

 pronotal band is paler, usually paler mesad than laterad, the 

 dark marking of the lateral lobes of the pronotum is very broadly 

 bordered by white ventrad, the tegmina reach to the apex of the 

 abdomen or 'slightly beyond and are green except for a longi- 

 tudinal humeral band, the caudal femora show faintly two trans- 

 verse bars on their dorsal surfaces and do not have their external 

 faces washed with pink. 



Type. — cf ; Carrabelle, Franklin County, Florida. September 

 2 to 3, 1915. (Rehn and Hebard.) [Hebard Collection, Type 

 No. 481.] 



Size small for the genus, form slender. Eyes very slightly more prominent 

 and showing a less decided difference between length and width than in 

 brevipennis. Medio-longitudinal dorsal band of pronotum not solidly pink, 

 the median portion distinctly paler than the margins. Dark bar of prozonal 

 portion of lateral lobes solid in coloration, the ventral border of this bar white and 

 about equally broad (in a few specimens of the series narrower, this feature then 

 showing no difference from brevipennis). Tegmina and wings fully developed, 

 as in H. pratensis Scudder, extending nearly to apices of caudal femora (in the 

 males at hand varying slightly, minimum extending to apex of abdomen, 

 maximum to apices of caudal femora). Tegmina distinctively colored; dorsal 

 and lateral fields green except for a broad longitudinal humeral band of pink 

 (the dorsal portion of this band in the lateral field usually darkened) . Genitalia 

 of the same general type as found in pratensis and brevipennis; 17 cerci alone 

 differing in being narrow and of subequal width in distal half, moderately 

 incurved in this portion, with apex sharply rounded. Prosternal spine shorter 

 and stouter than in brevipennis, tapering more rapidly in distal portion to the 

 sharply rounded apex. Antennae and broad annuli of cephalic and median 

 femora similar to brevipennis, except that they are not as brilliantly colored. 

 Caudal femora green, the pregenicular pinkish annulus distinct (but indi- 

 vidually variable, and obsolete in a few specimens at hand) ; dorsal surface pale 

 green with two weak but distinct broad transverse bands of darker green 18 

 and showing no trace of pink along the external margin as is characteristic of 

 brevipennis; external surface green (never washed with pink as in brevipennis) ; 

 dorsal half of lateral portions of genicular areas black as in brevipennis. 



17 In the present genus slight individual variation in the form of the subapical 

 tubercle of the male subgenital plate occurs. 



18 These bands are exceedingly delicate and in poorly dried material might 

 easily be obscured. No trace of such marking ever occurs in brevipennis.
