or truncate. Elytra and wings usually as long as the alxlomen, sometimes 

 abbreviated. Abdomen long and slender. Anterior legs very short and 

 slender ; posterior legs long and slender, the femora but slightly enlarged at 

 the base. Prosternum without spine or tubercle, narrow. 



Section. — Head ascending. Pronotum with the sides parallel ; anterior 

 border sub-truncate ; posterior border truncate. Elytra and wings abbi'evi- 

 ated. Posterior femora shorter than the abdomen. 



Tr. brevipennas, sp. nov. 



Female. — Top of the head longer than the pronotum; median carina not 

 very distinct, obtuse, a slight sulcus along each side. Vertex broad, that in 

 advance of the eyes abont equal to the eyes in length ; the median carina dis- 

 tinct on this portion, slightly sulcate; each side of the margins expanding 

 horizontally, and but slightly curved up. The entire head is elongate conical; 

 the four carinse of the face minute and obscure. The antennae scarcely longer 

 than the head, ensiform, triquetrous. Eyes elongate ovate, equal in length to 

 one-third the top of the head ; rather prominent, almost horizontal. Prono- 

 tum short, t'ricarinate, the three carinse equal ; front border obtusely rounded, 

 and advanced somewhat upon the back part of the head; hind border trun- 

 cate ; the anterior lateral margins as they ascend slope obliquely forward ; 

 the posterior lateral margins curve inward, leaving a somewhat acute angle 

 below. Elytra very short, not extending beyond the insertion of the posterior 

 legs; naiTow, lanceolate; longitudinal nerves prominent ; not meeting above. 

 Wings minute. Abdomen very long, sub-cylindrical, slightly carinated above; 

 ovipositor moderately long; super-anal plate longitudinally indented or grooved. 

 Posterior femora considerably shorter than the abdomen, slender. 



Color (alcoholic). — Almost uniform pale greenish-yellow — doubtless 

 green when living — immaculate ; the antennae, vertex, and posterior femora 

 pale rufous. 



Dimensions. — Length, 1.7 inches; top of the head, 0.28 inch; elytra, 

 0.25 inch; hind femora, 0.76 inch; hind tibiee, 0.74 inch. 



Florida (from Professor Glover's collection).* PI., Fig. 12. 



* I find this somewhat anomalous species in a bottle of Ortboptera collected by 

 Professor T. Glover at Pilatka, Florida. Its occurrence there was certainly unexpected 

 to me ; but he says he made the collection there in person, and most of the other speci- 

 mens in the same bottle are well-kiiowu types of the United States fauna. The speci- 

 mens may not be fully developed, but, judging from the ovipositor, they must be very 

 nearly perfect. The short wiugs and short femora may require tlie formation of a new 

 genus.
