XIV. Neotettix ITancoek (1898). 



The members of this genus have the body short and thick set. 

 Vertex wider than one of the eyes, the front margin convex or 

 rounded; viewed from the side^ a little advanced in front of the eyes. 

 Frontal costa convex, their lower halves, viewed in front, strongly 

 divergent or forked. Antennas rather stout, short, composed of 

 twelve or, rarely, thirteen segments. Pronotum with its front dorsal 

 margin truncate, advanced over the head to the eyes, the sides of dor- 

 sal surface sloping a little downward between the shoulders; the 

 median carina distinct, usually a little elevated between the shoul- 

 ders. Hind femora enlarged, rather short. Hind tarsus with the 

 first segment distinctly longer than the second and third together, 

 the pad between the claws of last segment acute but more or less flat 

 below. 



Five species of this genus are known from the United States. One 

 of these occurs in Indiana. 



23. Neotettix hancooki sp. nov. 



Body short, robust; color dark gray, the tibiffi and tarsi annulate 

 with light and dark, the ovipositor brown. A^ertex nearly twice as 

 wide as one of the eyes; its median carina visible only on front half; 

 its front border rounded. Frontal costa, viewed from the side, 

 strongly convex between the bases of antennae, the lower halves, as in 

 other species of the genus, widely divergent. Eyes prominent, sub- 

 globose. Pronotum with its dorsal front margin truncalc, reaching 

 the eyes; the lateral carinas on the portion in front of shoulders high 

 and distinct; the posterior portion with the sides converging gradually 

 to a rather sharp apex, which terminates just above the base of ovi- 

 positor; the median carina distinct throughout, more or less undu- 

 late, highest between the shoulders; the posterior lateral carina prom- 

 inent throughout; the dorsal surface with a number of prominent 

 oblong tubercles on its front half; those on posterior half shorter and 

 more rounded; tegmina oblong, the apical half rounded. Wings ab- 

 breviated, three-fourths the length of posterior portion of pronotum. 



Measurements: Length of body, female, 10 mm.; of pronotum, 

 8.5 mm.; of hind femora, G mm. 



From N. bolirari, its nearest ally, this species is easily recognized 

 by its more bulky form, by the more convex and prominent frontal 

 costse, the larger eyes, the higher lateral carinac of pronotum behind 

 the eyes, and especially by the prominent tubercles on the surface 

 of the front dorsal half of pronotum. The tegmina are shorter and
