ifl. solutlis Roll. — Oblong ellii)tical ; j)iceous. Above densely covered Avith 

 pale ochraceous scales; beak moderately stout; tricarinate ; median carina en- 

 tire, lateral ones abbreviated, indistinct; densely scaly. Scrohes attaining the 

 middle of eyes. Autennse fuscous, club darker. Head convex, finely punctured 

 .sparsely covered with piliform scales. Thorax subquadrate, scarcely wider than 

 long; sides almost straight, slightly narrowed at apex; densely punctate; 

 punctures moderate ; surface densely scaly ; scales round, of moderate size and 

 somewhat umbilicated, intermixed with very short, suberect hairs. Lateral and 

 median line of paler scales, latter often obsolete. Thoracic lobes moderately 

 prominent, only partially covering the eyes lii repose. Elytra one-half wider 

 than thorax, subconvex ; parallel for two-thirds their length, thence narrowed 

 and distinctly compressed towards apex, with the posterior callus rather evident. 

 Sti'ise fine; punctures subquadrate, not very closely placed ; intervals flattened, 

 each with a row of very short, inconspicuous setfe. A broad, dark, denuded, 

 subtriangular fascia, occupying the middle of each elytron, with the apex di- 

 rected toward the suture, which, however, is scarcely attained. Elytra rather 

 strongly inflexed in their ajiical half, causing the abdomen to appear somewhat 

 narrowed. Beneath, dark pic^ous, glabrous ; rather densely, but finely punc 

 tate, except first and second abdominal segments, where they are more distant; 

 each puncture bearing a short, scale-like hair. Legs rufo-piceous ; femora mod- 

 erately clavate. infuscate at middle and with a ring of pale scales near apex. 

 Length 3.5-5.0 mm. ; .14-.20 inch. 



Z . Last ventral segment not, or very slightly impressed longi- 

 tudinally. 



9 . Last ventral with a large, but shallow fovea ; elytra a trifle 

 wider behind middle. 



Hab. — New York, District Columbia, Iowa, Northern Illinois, 

 Kansas. 



lU. iiidistiiK'tus n. sj-. — Very simil.ir in form and appearance to solutus 

 from which it difi^ers by being a trifle stouter; thorax distinctly wider than 

 long, its prothoracic lobes rather more prominent and complete absence of de- 

 nuded elytral fascia. 



Sexual characters same as .solntas. This is probably L. spurcns 

 Boh. 



Hab. — New Jersey, New York, Illinois, Montana, Wyoming. 



M. cryptops n. sp. — Robust, piceous brown ; covered above and below with 

 rounded, grayish scales. Rostrum rather .stout, with a broad, shallow sulcus 

 between the lateral elevated lines; median carina feeble, generally concealed by 

 the scales Antennal grooves attaining the eyes rather below the middle. Eyes 

 subconvex and surrounded by a distinct groove, completely covered in repose by 

 the prothoracic lobes. Thorax subquadrate, moderately convex, slightly wider 

 at base than at apex. Sides almost straight for three quarters their length, then 

 slightly narrowed to apex; coarsely cribrate ; punctures almost hexagonal and 

 separated by very narrow ridges, each covered by a large, umbilicated .scale. A 

 narrow median and lateral line of paler scales. Postocular lobes very strongly 

 developed, causing the presternum to become more deeply emarginate. Elytra
