EVOTUS Lee. 



Eootu* Lcc., American Naturalist, 1874, pp. 458-9. 



Rostrum horizontal, longer than twice the head, narrower, sub-quad- 

 rangular and compressed at base, tip dilated and nearly twice as broad as 

 at middle, auriculate, and broadly emarginate ; gense not emarginate. 

 Sub-mentum distinctly pedunculate. Mentum oval, longer than wide, 

 maxillae slightly visible at the sides. Scrobes visible from above in front 

 and moderately deep, very nearly straight, very shallow posteriorly, and 

 directed to the lower margin of the eyes. Eyes oval, slightly oblique and 

 sub-acute beneath. Antennae long, rather slender ; scape gradually clavate 

 and attaining the middle of the eye ; funicle 7-jointed, slightly longer than 

 the scape, joints 1-2 longer, the second longer than the first, joints 3-7 

 obconical, the seventh longer than the preceding ; club elongate, oval. 

 Thorax transversely oval, apex truncate, base slightly arcuate. Scutellum 

 oval. Elytra oval, broader at base than the thorax, humeri obtuse, mode- 

 rately prominent. Metasternum moderate, side pieces wide, formed as 

 defined for the division. Intercoxal process broad, oval at tip. Second 

 segment of abdomen slightly longer than the two following together, 

 separated from the first by an arcuate suture. Anterior and middle tibia? 

 mucronate at tip. Articular surfaces of hind tibiae feebly cavernous and 

 glabrous. Tarsi rather slender, third joint deeply bilobed, last joint slender 

 and as long as the first two. Claws moderate, free. 



This genus has been defined at greater length than has been the custom 

 in this paper, on account of the very remarkable assemblage of characters 

 it presents. Were it not for the very plain scar on the mandibles it might 

 be suspected to have some affinity with the genera allied to Alophus, etc.

Form elongate, oval, color black shining, moderately densely covered 

 with scales, varying in color from ochreous to cinereous. Head and 

 rostrum longer than the thorax, moderately, densely punctured, sparsely 

 scaly, a fine median line, more distinctly impressed on the vertex. Thorax 

 oval, slightly broader than long, narrower in front, apex truncate, base 

 feebly arcuate, sides rather strongly arcuate in front ; median line indis- 

 tinct, disc moderately convex, densely punctured, scales sparse, except on 

 the median line and sides. Scutellum densely scaly and paler. Elytra 

 oval, moderately convex, with rows of moderate punctures, intervals 

 densely punctulate, surface moderately, densely scaly, and variegated with 

 paler spots at the sides. Body beneath and legs densely scaly and hairy, 

 scales pearly. Length .30-, 36 inch ; 7.5-9 mm. 



Occurs rather abundantly in Oregon, and also in Colorado.

Head prolonged behind the eyes, these round or slightly oval. Mentum 

 small, usually concealing the maxillae. Rostrum usually stout, cylindrical,
