distinct and narrow above the ocellus, fading, and diverging below it, upper 

 iiortion sharply sulcate ; lateral carinas distinct, curving outward. Antennae 

 about as long as the head and thorax, slightly enlarged near the base, and 

 acuminate at the apex, sub-triquetrous or slightly flattened. Pronotum about 

 as long as the head, slightly constricted in the middle; median carinse slight; 

 lateral carinse nearly obliterated, especially on the anterior lobes, slightly 

 approximating in the middle, nearly parallel thence to the front, diverging 

 posteriorly ; hind border sub-truncate. Elytra and wings about as long as 

 the abdomen. Hind femora reach the extremity of the abdomen. 



Color (dried after immersion in alcohol). — A broad, brown stripe on each 

 side extends from the upper corner of the eye, widening on the head, 

 extending along the upper part of the side of the pronotum, and reaching to 

 the hind mai-gin, a small portion passing over the diverging part of the 

 lateral carinse; usually a brownish stripe extends from the vertex along the 

 back of the head to the pronotum. Elytra pale-brown, with a row of fuscous 

 dots along the disk. 



Dimensions. — $• Length, 0.78 inch; elytra, 0.6 inch. $ Length, 0.62 



inch. 



Colorado, "Wyoming, and Southeast Idaho (Thomas). 



From the description the generic position of this species appears doubt- 

 ful, but the general appearance to the eye is evidently that of Stenobothrus, 

 therefore I place it here, though it is possible it belongs to Epacromia. 



Subdivision 2. — Antennse filiform, or slightly flattened, especially toward 

 the apex. 



Section 1. — Lateral carinse of the pronotum straight, or very nearly so. 

 parallel or very slightly approximate in the middle, and but slightly elevated. 



St. coloratlMisi, Thos.* 



Syn., St. hicolor, Thos., Geo!. Surv. Terr., 1871, 4G5. 



Lateral foveolse wanting. Two broad, brown stripes reaching from the 

 vertex to the tip of the elytra. 



Vertex scarcely expanding in front of the eyes ; margins scarcely raised, 

 obtuse ; a slight, indistinct median carinse ; the tip obtusely rounded. Face 



*It appear.s that Walker (Cat. Deriuap. Salt., V, Supp., 78) has restored the 

 hicolor of Oharp., as distinct from biguttulus, Burm.; therefore, as this part of his 

 catalogue was published a short time in advance of my description, it becomes 

 necessary for me to cliauge the uame of my species.
