in B. 7nagna,^ rather flatter above, transversely marked with dull 

 yellow and brown, the apex blac-k ; hind tibiaj yellow, infusoated 

 at the extreme tip, the spines wholly black. Abdomen brownish 

 yellow, the dorsum with a broad median fuscous stripe, sometimes 

 enlivened by a median luteous line, separated by a narrow subdorsal 

 luteous stripe from a broad, black or blackish, dorso-pleural stripe. 

 Indications of similar markings may often be seen in B. magna, but 

 they are never so inequal nor so intense. Length of body, d, 46 

 mm., ?, 55 mm.; of antennae, d, 27 mm., ?, 2% nun.; of pronotum, 

 d, 15.25 mm., ?, 17.25 mm.; of tegmina, 8 mm., width of same, 6.75 

 mm. ; length of hind femora, d", 30.75 mm., ?, 25.75 mm.

69. Tettigidea Obesa. Shining nigro-fuliginous, the dorsum 

 of pronotum sometimes dull plumbeo-testaceous ; lower two thirds of 

 face of male and lower third of deflected lobe of pronotum pale clay 

 brown; legs and tegmina black, the hind femora sometimes with an 

 inferior premedian and superior preapical minute testaceous spot. 

 Body very robust and unusually smooth, the entire head and pro- 

 notum being depressed, rugulose and shining; all the angles are 

 rounded. The fastigium of the vertex is broadly rounded in front, 

 scarcely projects beyond the eyes, but the median carina, continuous 

 with the frontal carina, is conspicuous and prominent, compressed, 

 though with rounded surface ; the frontal costa is very prominent, 

 broadens slightly below, and is very narrowly sulcate; seen from the 

 side, it projects beyond the eyes fully half their width, and is broadly 

 convex. The pronotum reaches the tip of the abdomen only, is 

 produced and very convex in front, and, at least in the females, is 

 fully twice as broad in the middle as in front; its sides are consider- 

 ably deflected, so that the median carina is elevated and equal 

 tliroughout, though blunt, and on a side view somewhat arched. The 

 ten^mina are almost smooth, and the wings scarcely longer than the 

 pronotum. Length, d, 9 mm., $,12 mm. ; of antennae, d, 3.75 mm., 

 ?, 4 mm.; of hind femora, d, 6 mm., ?, 8 mm. 



3 d", 3 ?. Georgia, H. K. Morrison. The heavy, smooth and 

 rounded body of this insect readily distinguishes it from any other 

 Tettigidean known to me. 



70. Tettigidea prorsa. Varying from dark testaceous to 

 blackish, generally darkest on the sides, but the face and lower third 



I The hind femora of the females are much slenderer than those of the males in 

 this genus.
