rather regularly sprinkled with small brownish spots. Basal half of the

 at the extreme tip. Hind femora dull-hoary outside, black, with three 

 white bands, inside ; tibiae blackish-brown, with black spines, and a broad

Closely allied to CE. sulphurea, Burm. Upper part of the head regu- 

 larly convex; central foveola of the vertex sub-elongate, divided by a median 

 carina into two sub-pyriform parts, generally truncate and closed in front; 

 upper part of the frontal costa dimly sub-tricarinate, rest flat, slightly 

 impressed at the ocellus, prominent. Face, seen from the side, arcuate 

 below. Antennae somewhat flattened and enlarged toward the apex. Me- 

 dian carina of the pronotum distinct, somewhat prominent, nearly straight on 

 top, cut near the middle, but not notched ; anterior margin obtusely rounded ; 

 apical angle a little more than a right angle ; lateral carinas sub-distinct ; disk 

 of the posterior lobe nearly flat. Elytra and wings pass the abdomen. 



Color. — Nearly uniform dark -fuscous, males often quite black ; front of 

 head with somewhat pale markings. Pronotum above, dull dirty-yellow, with 

 dots and streaks of fuliginous ; hind femora banded, with yellow near the 

 apex ; hind tibiae with a dull-reddish band next the base, followed by a darker 

 band. Eljtra almost uniformly mottled with fuscous, the outer half inter- 

 spersed with paler spots. Wings pale-red at the base, the whole outer border 

 obscured by a broad, dark, fuliginous band, slightly paler at the extreme tip, 

 projecting sharply inward almost to the base of the wing near the costal 

 margin. Antennae fuscous, basal third j^aler. 



Dimensions (according to Scudder). — 5 Length to tip of elytra, 1.8 

 inches. <? Length to tip of elytra, 1.25 inches.
