Evashmeadea Godg. by the lack of sinuation on the dorsal crest. Atymita 

 and Cyrtolobus are differentiated by the position of the highest portion 

 of the crest. In Atymna the highest portion of the crest is anterior to 

 to dorsum, rising above the humeral angles, while in Cyrtolobus the 

 highest portion of the crest is near the middle of the dorsum. 



Of this subgenus Kansas has recorded but one species, Cyrtolobus can 

 Say. Figs. 24, 2.5, 79. 



This species is pale brown or tan; frequently banded with both darker 

 and lighter shades than the ground color. The crest is evenly arcuated, 

 and in some cases very little elevated. The metopidium is transversely 

 rounded, the crest beginning to rise back of the humeral angles. The 

 dor.sum is rounded from its ventral edges and the crest is formed by a 

 sharp compression. At times this crest is made manifest only by a 

 distinct and prominent median dorsal carina. The pronotum does not 

 extend to the tips of the tegmina, but covers the abdomen. The carina 

 is usually darker than the rest of the pronotum. The color marking, 

 when present, consists of three dark spots along the lateral side of the 

 dorsum, cut into by two streaks of light on the crest or carina, but joined 

 together on the lower edge of the side of the dorsum. Posterior process 

 is light if the color markings are present; otherwise it is light and con- 

 colorous with the pronotum. The face is usually void of color markings, 

 and is short, with a broad clypeus rounded at the apex, and black, shiny, 

 compound eyes. Legs pale and slender; pectus pale. Tegmina distinctly 

 veined and transparent except near the tip, where it commences to be- 

 come smoky, and continues so to the very tip. 



Length, 6.5 to 5 mm. 



Habitat: Colorado Springs, Colo.; Kansas City, Mo.; Columbia. Mo.; 

 Pennsylvania.; Douglas county, Kansas. 



II.— Subfamily MEMBRACIN^ Stal. 



This subfamily is differentiated from the others by the dilated or 

 foliaceous tibia. In this subfamily are placed the two genera Eiichenoim 

 and Caiiipyleiichia, which together are separated from the other mem- 

 bers of the subfamily by the pronotum being distinctly compressed and 

 elevated toward the front into a prominent, usually oblique process. 

 This process is further characterized by the lateral carina attaining the 

 middle of the posterior process. 



The two genera are separated from each other by the position of the 

 lateral carinae: 



.\. Lateral carin:*. of tlie anterior jiroces-s simple, placed about equally distant fniin tlie 

 upl)er atid lower niaririns. Carina- foliaceous. Pronotum without pubescence.

1.— Genus Evcheno-pa A. & S. Figs. 12, 13, 71, 85. 



In this genus Kansas has recorded but one species. This one, however, 

 is very common and of wide distribution. Enchenopa biiiotata Say may 

 be distinguished from the other species of this genus by its dorsal carina 

 being very prominent posteriorly. The insect is of a reddish brown, while
