Nomotettix compressus, sp. (?)'nov. 



Very similar to /V. cristatus Harris, resembling it in size and proportions of 

 boily, but differing as follows: Median carina of pronotum a little higher, especially 

 opposite the shoulders, more smoothly arched on top, and distinctly compressed 

 into a thin keel, which is about i mm. in height at the shoulders and so thin in 

 section that the punctulations of its surface appear translucent when held to the 

 light. Dorsal front margin of pronotum much advanced upon the head, projecting 

 over it a distance nearly or quite equal to one-half the distance between the lateial 

 caiina\ with the sides strongly concave, — in cristatus projecting but one-fifth to 

 one-third the above distance and with the sides less excavated.

Such are the characters presented by a series of 2 i^, 5 O, proba- 

 bly from North Carolina, presented by Prof. G. F. Atkinson to 

 Cornell University (lot 105). 



While at first disposed to consider it a distinct species, subse- 

 quent examination of material from Indiana, Maryland, and Geor- 

 gia seems to indicate that it may grade into the typical New Eng- 

 land form of cristatus, the pronotum in some of these specimens 

 having the carina less distinctly compressed and the anterior 

 margin less produced. Additional specimens in suites, with 

 observations on altitude, environm.ent, etc., are necessary in order 

 to settle the relation of the two forms satisfactorily, whether 

 racial or specific. 



Tettigidea acuta, sp. nov. 



Very similar to northern specimens of 7\ lateralis, differing as follows: .Anterior 

 margin of ])ronotum produced into an acutely pointed process, reaching nearly to 

 the mid-carina of verte.\; 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 ruguliK; mid-carina 

 distinct, but slight, especially at shoulders, where the pronotum is nearly convex 

 in cross section, instead of tectiform. From (r/^/c^/ifAr it may be readily distinguished 

 by the vertex. 



Color brown to dark brownish fuscous, more or less of the top of pionotinu 

 straw-colored. Elytral pale spots rather larger than in tati-rali.w
