HANCOCK i6i 



5.5 mm.; j, body, 12. 5 mm.; pronot., 11 mm.; post, fem., 

 6.5 mm. 



Locality, Mexico, Cindad, in Durango, 8, 100 feet (Farrer). 



Two males and one female. This species resembles T. 

 prorsa, but differs from it in the more angular front margin of 

 the pronotum, wider vertex, more prominent eves, and 

 stouter hind femora (Morse). 



Tettigidea tecta, Morse, Biol. Cent. Am. Orth.. 15, 17, 

 18 (1901); Scudder, Index N. Am. Orth., 316 (1901). 



GEN. PLECTRONOTUS, morse. 



Nearly allied to Tettigidea in general structure, but differ- 

 ing from it in the form of the facial costa, the minute elon- 

 gate elytra, and especially in the structure of the pronotum, 

 which is coarsely scabrous, with the posterior sinus of the 

 lateral lobes all but obsolete and the angles a little reflected. 



Plectronotus, Morse, Biol. Cent. Am. Orth., ii, 14 (1900). 



PLECTRONOTUS SC.\BER, MORSE. 



Antenna;, 21-22-jointed, slender, filiform, about reaching 

 the base of the hind femora. Eyes of moderate size promi- 

 nent. Vertex scarcely {t), or one and one-half times (5), as 

 wide as one of the eyes, truncate in front, the mid-carina of 

 moderate size and but little produced backwards; the front 

 margin transversely carinate, the carinula; and surface imme- 

 diately behind them slightly depressed. Crown horizontal. 

 Facial costa rather broadly sulcate, the margins sinuous, 

 approximated below the points of insertion of the antennae; 

 in profile, strongly convex opposite the lower margin of the 

 eyes, moderately concave opposite the middle of them. Pro- 

 notum tectiform very coarsely scabrous, granulate; the front 

 margin advanced, with concave sides and uncinate apex 

 extending to the end of the mid-carina of the vertex, a little 

 behind the level of the front of the eyes; the hind process 

 abbreviated, its sides convex, apex acute; lateral lobes rather 

 deep, the posterior angles acute, somewhat rounded at the tip 

 and turned a little outward, the posterior sinus barelv indi-
