14. CE. cosTALis, nov. sp. 



Brownish-yellow, profusely mottled with reddish-brown ; 

 a broad yellowish band extends from each eye to the 

 opposite outer posterior angle of the pronotum, crossing 

 at the middle of the pronotum, bordered outside with a 

 broad band of black, narrowing posteriorly to a line, and 

 inside, behind the intersection, by a broad black band, 

 which has another narrow short black line parallel to it at 

 the hind border of the pronotum; medial carina of prono- 

 tum equal, rather sharp, not high ; wing-covers much as 

 in (E. sordida ; wings pellucid, with a faint cloudy patch 

 at the middle of the outer border, and a dark streak along 

 the costal border toward the apex ; hind femora yellowish, 

 with two transverse dark annulations, the tips dark brown ; 

 hind tibite bluish with black spines and a yellowish annu- 

 lation at base. This species differs from (E. sordida, in 

 the markings and lowness of the ridge of pronotum, and 

 in the shorter and fuller wings.
