bone brown marking at the proximal portion of the free margins 

 forming a single large median spot when the tegmina are closed. 

 The lateral angles of the pronotum are pale yellowish with the 

 lateral lobes just below these marked with an obscure band of 

 brown. The abdominal segments are marked meso-laterad with 

 maculations of bone brown forming a broad but interrupted 

 stripe. The cephalic and median femora are speckled with bone 

 brown and are further irregularly and narrowh' biannulate with 

 this color. In the female the distal portion of the cerci and 

 proximal portions of the basal plicae of the ovipositor are unusu- 

 ally dark for the species of the genus. 



Jacksonville, Florida, is the only locality laiown for this un- 

 usual and striking species, which must be considered one of the 

 rarest, most local and probably least widely distributed species 

 of North American Orthoptera. 



Specimens Examined: 2; 1 male and 1 female. 



Jacksonville, Florida, (T. J. Priddey), 1 cf, 1 9, type, allotype, [Hebard 

 Cln. ex Brunerj. 



Scudderia hemidactyla new species (PL IX, figs. 11, 15, 16 and 17; pi. 

 X, fig. 22.) 



A very distinct and anomalous species showing a certain amount 

 of affinity to S. se'ptentrionalis in the decided reduction of the 

 supra-anal plate in the male and in the similar subgenital plate 

 in the same sex, which is however less decidedly angulate-emar- 

 ginate distad. The production of the supra-anal plate in the male 

 bears distad small, strongly compressed, vertical lateral flanges; 

 the greatest similarity m this character is found elsewhere in the 

 genus in S. texensis, but in all other characters of this reduced but 

 greatly specialized appendage the species is unique. The species 

 is very gloss}^ with rather more prominent eyes than is usual in 

 the genus, in these respects resembling S. paronae. Characters 

 of the pronotum and armament of the caudal femora separate the 

 species further from any other of the genus. 



Type. — cf; Caparo, Trinidad, June, 1913. (S. M. Klages.) 

 [Acad. Nat. Sci. Phila., Type No. 524.] 



Description of Type. — Similar in size to typical S. furcata furcifera but 

 with deeper lateral lobes of the pronotum, more attenuate tegmina and 

 shorter limbs. Head similar to S. paronae, but with inter-fastigial suture 

 narrower; inter-ocular space decidedly narrower and ej'es larger so 

 that when seen from above the inter-ocular space is not as wide as one of
