f. Tegmina at middle distinctly broader than length of pro- 

 notum; disk of pronotum with side margins diverging 

 backward, subacute, not broadly rounded into the per- 

 pendicular lateral lobes. 214. CUKVICATJDA. 

 //'. Tegmina narrower, at middle no wider than length of 

 pronotum; side margins of pronotum more parallel, 

 broadly rounded into the more sloping lateral lobes; 

 ovipositor distinctly broader, less suddenly bent up- 

 ward. (Fig. 153, c.) 214a. LATICAUDA. 

 del. Tegmina much narrower than the length of pronotum. 

 strongly reticulate, each with a blackish-brown stripe along 

 its dorsal field; notch of abdominal process very shallow, 

 the lobes each side short, broad, strongly flattened; lateral 

 angles of pronotum broadly rounded; ovipositor wider at 

 base than at middle (Fig. 153, f.) 215. STRIGATA. 

 l>b. Apex of decurved abdominal process of male distinctly and deeply 

 forked (Fig. 152, g, h), usually embracing the sides of the up- 

 curved subgenital plate; size smaller and form more slender 

 than our other common species. 



g. Lobes of forks of abdominal process shorter, subcylindrical, 



rounded above, widely separated at tips. 216. FURCATA. 



gg. Lobes of forks of abdominal process obliquely compressed, their 



upper edges subacute, more narrowly separated, especially at 



tip. 216a. CUNEATA.

211. SCUDDERIA SEPTEXTRIONALIS (Serville), 1839, 416. Northern Bush- 

 katydid. 



Size very small for the genus; form slender. General color pale green 

 more or less tinged with yellow; tegmina, basal half of pronotum, hind 

 femora and all the tibiae a uniform rather dark green; apical half of an- 

 tennae brownish. Disk of pronotum with sides feebly divergent behind, 

 lateral carinae evident only behind middle, basal lobe broader than in /S. 

 furcata. Tegmina shorter and broader than in furcata, more strongly reti- 

 culate and of a coarser texture. Male abdominal appendages as described 

 in key, the subgenital plate narrowing gradually, strongly upcurved, its 

 apex deeply and broadly notched. Ovipositor one-third as broad as long, 

 gently curved, finely crenate above (Fig. 153, a.) Length of body, $, 16 

 18.5, 9, 20; of pronotum, $, 4.7, 9,5; of tegmina, $, 2528, 9, 2627; 

 of hind femora, $ and 9, 18 19.5; of ovipositor, 8.7 mm. Greatest width 

 of tegmina, , 1 7.3, 9, 7.5 mm. (Fig. 154.)
