LECONTE ON ROCKY MOUNTAIN COLEOPTERA. 463 



40. ChRYSOMELA MONTIVAaANS, n. sp. 



Apterous, oval convex, bluish or black, slightly bronzed, moderately 

 shining. Prothorax sparsely but not coarsely punctured, longitudinally 

 sulcata and coarsely j)unctured each side, margin strongly incrassed, 

 sides rounded. Elytra sparsely punctured. * Length G.T'"'" (0.27 inch). 



Mount Lincoln (11,000 to 13,000 feet); found also by Prof. F. H. 

 Snow. This species is closely allied to G. miripennis Say, and resembles 

 the dark varieties ; it differs by the sides of the prothorax being regu- 

 larly and rather strongly rounded, by the wings being undeveloped, and 

 by the elytra being much less coarsely punctured. 



CUECULIONID^. 



41. Magdalis alutacea, n. sp. 



Elongate cuneiform, black, slightly bronzed, opake with a silky lus- 

 tre. Beak slender, curved, as long as the head and prothorax, finely 

 punctured. Head feebly punctulate. Prothorax a little longer than 

 wide, narrowed in front, sides not serrate, broadly rounded, then slightly 

 sinuate; hind angles acute, divergent; surface very densely, but not 

 coarsely, punctured. Elytra, with striae composed of small, quadrate, 

 approximate punctures, interspaces flat, finely alutaceous. Femora 

 acutely toothed; claws entire, not toothed. Length 42'"'" (0.17 inch). 



Leavenworth Yalley, above Georgetown, Colo., (9,000 to 10,000 feet) ; 

 Isle Eoyale, Lake Superior, Mr. E. A. Schwarz. This species differs 

 from M. imbellis by finer sculpture, less rounded sides of the prothorax, 

 and black color; from M. gentilis LeG. by the divergent hind angles of 

 the prothorax, by the less convex and less deeply striate elytra; the 

 interspaces are wider, and not rugose, but alutaceous.
