LECONTE ON ROCKY MOUNTAIN COLEOPTERA. 461 



reflexed. Elytra parallel, not wider than tlie prothorax, rather shining, 

 densely rugose as usual, separately rounded at the tip. Last three 

 dorsal segments of the abdomen exposed. (Palpi broken.) Claws with 

 a small acute tooth beyond the middle. Length 87°^"" (0.35 inch). 



Argentine Pass, Col., (13,000 feet) ; one specimen. This species is 

 quite distinct by the more robust form and shorter elytra. 



MELYRID^. 



33. Meltris atra, n. si). 



Black, j)rothorax wider than long, narrowed in front, rounded and 

 serrate on the sides, densely reticulated with shallow ocellate punctures. 

 Elytra coarsely but densely punctured. Antennae black, 2d and 3d 

 joints piceous. Legs piceous. Length 5™°^ (0.20 inch). 



^ unknown ; 9 elytra with a large smooth spot near the tip ; antennae, 

 1st and 2d joints large and thick ; 3d slender, longer than the 2d ; 4th 

 and 5th triangular ; 6th to 9th transverse ; 10th oval. 



Beaver Brook, Col., (6,000 feet) ; one specimen. I can see but ten 

 joints in the antennae; the legs are dark-colored, but otherwise this 

 species is very closely allied to the next. 



34. MeLYRTS FLAVIPES, 11. Sp. 



Black, with a blue reflection ; form and sculpture as in M. atra, but 

 smaller; antennae piceous towards the base. Legs bright reddish-yel- 

 low. Length 3.3°^°^ (0.13 inch). 



^ elytra uniformly punctured toward the tip. Antennae black, 11- 

 jointed; 3d joint as long as the 2d, triangular; 4th triangular, shorter; 

 5th and 6th transverse, not longer, but wider, and acute at the inner 

 side ; 7th to 10th transverse, still wider ; 11th oval. 



2 elytra each with a smooth spot near the tip. Antennae 10-jointed, 

 piceous at base, 3d and 4th joints slender, closely united, together 

 longer than the 2d; 5th and 6th acutely triangular; 7th, 8th, 9th, and 

 10th wider ; 11th oval. 

 California ; one pair ; locality unknown. 



35. CALLIDIUM JANTHINinH. ' 



Specimens collected in the Eocky Mountains do not differ essentially 

 from Canadian individuals of this well-known species. There are, how- 

 ever, allied races from Texas, California, and Idaho, of which I do not 

 possess sufficiently large series to enable me to define them with pre- 

 cision. Careful observations of the habits, food-trees, and structural 

 differences of the blue Callidia of this continent are much needed. The 

 comparison of our species, when properly investigated, with those of 

 the Palaearctic region promises well for the investigation of possible 

 changes produced by differences in food and locality. 



36. Crossidius Allgewahri, n. sp. 



Piceous without lustre, very densely clothed with dirty-yellow hair. 

 Prothorax rounded on the sides, feebly or not at all tuberculate ; punc-
