9 antennae blackish, tinged with testaceous especially at base, pectinate ; 

 wings with broad transverse band dusky. 



Colorado, one $ , collected by Prof. E. A. Popenoe, to whom' I dedi- 

 cate it in recognition of his excellent labors in making known the 

 Coleopterous fauna of Kansas. Differs from M. semijinva and scabra 

 by obtusely rounded vertex and smooth prothoras. and by first joint 

 of hind tarsi. 



91. iievadicus. — Black, head hairy with short erect cinereous hair, front 

 flat, vertex elevated, obtusely conical, punctulate. Prothorax shining, sparsely 

 pubescent, not densely punctured, smooth in front and near the sides. Scutel 

 smooth. Elytra nearly smooth, obtusely rounded, entirely honey-yellow. Be- 

 neath finely punctured. Hind tarsi with first joint as long as the fourth, slightly 

 thickened, obliquely truncate and emarginate at tip. Length 5 mm. 



% antennae brown, plumose, front legs yellow, lower margin of middle thighs 

 and middle tibise testaceous; hind tibiae at tip and base of tarsi tinged with 

 testaceous ; wings hyaline. 



9 antennae black, pectinate; front legs tinged with testaceous; wings with 

 anterior margin and broad transverse band dusky. 



Nevada, H. K. Morrison. I am indebted to Dr. Horn for a pair of 

 this species. 



Jfl. califomicns. — Black, head hairy with erect grayish pubescence, front 

 flat, vertex broadly rounded, densely punctulate; prothorax finely and densely 

 punctulate. Scutel smooth. Elytra shining, honey-yellow, finely very sparsely 

 punctulate. Beneath densely finely punctured. Hind tibiae Avith the first 

 joint as long as the others united, scarcely thicker, not emarginate at tip. 

 Length 5 mm. 



One 9 , California; precise locality unknown. The antennae and legs 

 are entirely black, and the wings very faintly fasciate with dusky. 



M. Zeschii. — Black; head very densely punctulate, front flat, vertex 

 pubescent with erect hair, acutely conical and very prominent. Prothorax 

 densely punctulate. Scutel smooth, shining. Elytra opake, densely rugose 

 and punctulate, dull fulvous, with a large humeral spot and posterior trans- 

 verse blotch blackish. Beneath densely and finely punctured. Hind tarsi 

 with first joint as long as the others united, slightly compressed, not distinctly 

 emarginate at tip. Length 6.5 mm. 



% antennae smoky testaceous, plumose; front and middle legs dull testa- 

 ceous, middle tibiae and hind legs piceous; middle of first three ventral seg- 

 ments slightly yellowish. 



One % found at Buffalo, N. Y., was kindly given me by Mr. F. 

 Zesch, to whom I take pleasure in dedicating it. The wings are 

 unusually dark and the dusky band occupies nearly the apical third 

 of the surface. 



M. Schwarzi. — Black; head very densely punctulate, front flat, vertex 

 pubescent with erect hairs, obtusely prominent and slightly carinate. Pro- 

 thorax densely punctulate, with a small smooth callus each side in front of 

 the middle. Scutel shining, smooth. Elytra opake, rugose and punctulate.
