462 BULLETIN UNITED STATES GEOLOGICAL SURVEY. 



tures dense, concealed by the hair. Elytra densely and finely, but not 

 distinctly punctured, rounded at the tip ; sides broadly testaceous, 

 blending imperceptibly with the dark color. Beneath festaceous, very 

 hairy, antennae and legs blacls. Length 10-13.3'""' (0.40-0.53 inch). 



Atlanta, Idaho, (7,800 feet) ; collected by Mr. L. Allgewahr, to whom 

 1 dedicate it, as a mark of his worthy appreciation of the importance 

 of scientific investigation. The specimens were kindly given me by 

 Mr. Eeinecke, of Buffalo, N. Y. 



This species is more nearly related to C. humeralis than to the others, 

 but differs from it, as from all, by the very finely punctured elytra. 



In the smaller specimen, there is a faint and perhaps illusive appear- 

 ance of a lateral prothoracic tubercle, which is produced mainly by the 

 projection of hairs. 



37. Xylotrechus undulatus, var. ? 



A form occurs which differs from the usual Northern specimens of this 

 species by the markings being narrow and imperfect, and the sculpture 

 of the elytra more distinct. It is not uncommon in the Eocky Mountain 

 region, and was found by Mr. Bowditch at Florissant (8,000 feet). 



38. Neoclytus ascendens, n. sp. 



Very elongate, similar in form and sculpture to JV^. leucozonus. It differs 

 by the prothorax being less muricate along the dorsal line, and more 

 distinctly and coarsely punctured towards the sides. Elytra very finely 

 granulato-punctate, base, short sutural line from the base for one-fourth 

 the length white pubescent ; this line diverges from the suture and 

 then ends; there is also an oblique fascia just behind the middle, which 

 runs backwards from the suture and nearly attains the sides of the 

 elytra '. it is connected at its outer end with a submarginal gray stripe, 

 which ascends forwards to within one-fifth from the base ; another pos- 

 terior band, with oblique anterior margin, occupies the apical one- 

 sixth of the elytra ; tips rounded. Antennae slender, more than half 

 the length of the body. Posterior femora extending to the tip of the 

 elytra. Length 8.5°''n (0.34 inch). 



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

 one specimen. 



CHRYSOMELIDiE. 



39. Glyptoscelis longior, n. sp. 



Subcylindrical, narrower than G. albida, bronze color, clothed with 

 white hair (which is mostly rubbed off" in the specimen). Head densely 

 punctured. Prothorax a little wider than long, slightly narrowed in 

 front, hind angles acute, prominent laterally ; disc less coarsely punc- 

 tured than in G. albidus, obliquely impressed each side near the hind 

 angles. Elytra punctured as in that species. Length S.S'""* (0.225 

 inch). 



Que 9 . Atlanta, Idaho ; Mr. O. Eeinecke. Easily distinguished from 

 G. albidus by the narrower form and louder prothorax.
