144 TETTIGID.K OF NORTH AMERICA 



Tettigidea apiculata, Morse, Jour. N. Y. Ent. Soc. iii, 

 i6 (1895); Scudd., Cat. Orth. U. S., 18 (1900): Scudd., Inde.x 

 N. Am. Orth., 314 (1901). 



TETTIGIDE.A ACUTA, MORSE. 



Very similar to northern specimens of T. lateralis, differ- 

 ing as follows: Anterior margin of pronotum produced into an 

 acutely pointed process, reaching nearly to the mid-carina of 

 vertex; the latter is less prominent opposite the lower part 

 of eyes and higher on top of head, and the occiput is less 

 protuberant. Dorsum of pronotum smoothly granulated, with 

 very faint, irregular ruguL-e; mid-carina distinct, but slight, 

 especially at shoulders, where the pronotum is nearly convex 

 in cross section, instead of tectiform. From apiculata it may 

 be readily distinguished by the vertex. 



Color, brown to dark brownish fuscous, more or less of 

 the top of pronotum straw-colored. 



Elytral pale spots rather larger than in lateralis. 



Length of body, $, 16. 8-17. 3 mm.; pronot., 15. 5-15. 8 

 mm.; hind fem., 8 mm.; pronotum passing hind femora, 

 1.5-2.5 mm.; wings passing pronotum, 1.-1.4 mm. 



Locality, New York (Morse). 



Tettigidea acuta, Morse, Jour. N. Y. Ent. Soc, iii, 15, 

 16 (1895); Scudd., Cat. Orth. U. S., 18 (1900); .Scudd., 

 Index N. Am. Orth., 314 (1901). 



TETTIGIDEA SPICATA, MORSE. 



Plate X., Fig. 5. 



Body small, slender, intermediate in structure of vertex 

 between apiculata and ariiiata, but more nearly allied to the 

 latter. Vertex more projecting than in armata; the body 

 narrower between the shoulders; the lateral carinse of pro- 

 notum slightly developed; the median carina less distinct; the 

 dorsum more finely rugulose. 



Length of body, J, 11.6 mm.; juonot., 10.5 mm.; post. 

 fem., 5.5 mm.; $, body, 15. 6-16. 2 mm.; pronot., 14.4 mm.; 

 post, fem., 7.6 mm. Antenna; of male 3.3 mm., J, 4 mm.
