208 Coleopterological Notices, III. 



constricted in apical fifth, the apex truncate, three-fifths as wide as the base, 

 the latter broadly, obtusely angulate ; disk feebly impressed in the middle 

 toward base, finely, rather strongly punctulate, also very coarsely variolate, 

 the punctures sparse ; pubescence forming a broad oblique marginal and nar- 

 row median vitta. Elytra a little more than twice as long as wide, not more 

 than two and one-half times as long as the prothorax and slightly wider than 

 the latter, rather narrowly parabolic at apex, without distinct sutural notch ; 

 sides subparallel ; disk with feeble scutellar impression, and unimpressed 

 rows of coarse deep rather close-set punctures. Abdomen with longer pubes- 

 cence, denser behind. Legs short, moderately slender, somewhat sparsely 

 pubescent, the femora subannulate with denser hairs near the apex, the 

 posterior tibiae extremely short when compared with the corresponding femora. 

 Length 6.4-8.5 mm. ; width 1.8-2.9 mm. 



Arizona; Utah. 



A good series before me shows that while allied rather closely to 

 perforatus, the present species differs conspicuously in the shorter 

 thicker beak, more robust form of the body and different elytral 

 ornamentation, this latter being however an amplification and de- 

 velopment of the vague pattern observable in well-preserved ex- 

 amples of perforatus. In the latter, even in perfect specimens, the 

 third interval is never vittate except behind the middle and near its 

 point of juncture with the marginal vitta, the fifth never vittate, 

 and the somewhat shorter vestiture is more or less confusedly and 

 strongly mottled toward the sutural parts of the disk; this mottling 

 is never so distinctly observable in semivittatus and is generally 

 completely invisible. 



24 L,. macer Lee— Proc. Am. Phil. Soc, XV, p. 160. 



The specimens before me are from Illinois, Kansas, and Utah. 

 Macer is a large and conspicuous species, of slender cylindrical 

 form, shining integuments and sparse, finely and distinctly nucle- 

 ated vestiture which becomes denser along the sides of the upper 

 surface. The beak is longer and more developed than in any of 

 our other species, in the female being nearly twice as long as the 

 prothorax, and it differs also from any other known to me in the 

 basal constriction of the elytra. Length 14.5-18.0 mm.; width 

 3.8-4.8 mm. 



25 L.. jiiliclli n. sp. — Rather stout, elongate, subelliptical, moderately 

 convex above, shining, black throughout, the antenna? dull piceo-rufous with 

 blackish club ; vestiture very short, squamiform, sparse and more or less finely, 

 sparsely mottled, gradually denser toward the sides of the upper surface and 

 subdenuded near the lateral thoracic vitta. Head and beak rather finely but
