the liiiid ft'inorji, lirownish fuscous, with a coiiKpiruous, sleiultT, alter 

 Dating series of dark fuscous and lutcous quadrate sjiots alon^ tin* 

 middle line; wings not very broad, hyaline, the veins fuseo luteous. 

 Fore and nii<ldle femora very slijj^htly enlarjjetl in tiie male; hind 

 femora slender, compressed, luteo testaceous, very obscurely and on the 

 sides obliquely bifasciate with fuscous, most distinctly on the upper 

 fac«', the geniculation more (u* less infus(;at.'d; hind tibiae luteo-testa 

 ceous, the spines black beyond the base, t«'n to twelve in number in the 

 outer series. Extremity of male abdomen clavate, a little recutved, the 

 su])raanal plate subtrianj^ular with ex^)anded base and feebly annulate 

 sides, the apex subrectan^ulate, the apical third a little tumid and dis- 

 tinctly eh'vated above the median portion, the median sulcus deep, 

 pe re urrent, narrow in the middle and expandi d at both extremities: 

 fnrcnla consisting of a i)air of adjacent, subparallel jirocesses, each of 

 which consists of a tumid base bearing an apical, equal, slender, arcuate 

 projection hardly lonj:fertha' the base; cerci with asubecjual, rectan«»u 

 late basal portion, straight but transversely arcuate, more than half as 

 long again as broad, the upper ajucal corner of which is produced as a 

 slightly twisted rounded subspatulate lobe, hardly longer than broad, 

 incurved and exteriorly sulcate, about two thirds as broad as theba-al 

 portion, which is thus rectangulate at its lower apical extremity; sub 

 genital plate small, narrow, apically narrowed, the apical margin a little 

 incrassate, entire, not elevated. 



Length of body, male, 17 mm., female, 22 mm.; antennae, male, 8 mm., 

 female, 7.5 mm.; tegmina, male and female, 15 mm.; hind femora, male. 

 11.75 mm., female, 13.5 nmi. 



One male, 3 fenuiles. Munsons Hill [Kentucky?], July 12 (Museum 

 Comparative Zoology); Newport, Campbell County, Kentucky, C. M. 

 Willard same). 



The single female from Newport is placed here with some doubt on 

 account of its divergence from the others; and all the specimens have 

 been dried after long immersion m alcohol, bleaching the colors to some 

 extent, and contrticting some of the parts.

Of medium size. Head rather small, subcompressed, not elevated, 

 moderately arched; eyes moderately prominent; interspace between 

 the eyes as broad as the length of the basal antenual joint; fastigiuiii 

 very shallow, with moderately sharp but not prominent lateral walls, 

 which give it a subspatulate form ; frontal costa rather broad, above 

 slightly tumid, with puuctulate sides, scarcely broader below, sulcate 

 at the ocellus and to some degree below it. Pronotum rather slender, 

 rather uniform but distinctly broadening on the metazona, which is 

 separated from the prozona by a considerable dei)ression and a pretty 

 deep sulcus; metazona rather distinctly punctate; median carina dis
