224 AMERICAN COLEOPTERA. 



Described from a single male taken by Prof. Cockerell at an alti- 

 tude of 11, 000 ft. in the Las Vegas Range. 



There are no apparent sexual modifications of the legs, but the 

 first ventral bears at the middle two longitudinal parallel lines of 

 erect hairs, a character which will at once distinguish the present 

 species from any other in our fauna ; the truncation of the elytra is 

 also more pronounced than in any other species known to me. Alti- 

 cola may follow ovata in Horn's table. 



MONOTOMID^. 



Europs !«triatulus n. sp. — Form of ion^icoZZis but smaller aud somewhat 

 paler in color; anteunal club subequal iu length to the six preceding joints united 

 (about equal to the four preceding in longicollis). Head and prothorax less closely 

 but relatively quite as coarsely punctate as in longicollis; tenipora about one-third 

 the diameter of the eye ; prothorax just visibly narrower posteriorly, punctuation 

 sparser along the median line which is, however, not at all impressed; elytia 

 very finely striate, the strife finely punctate, interspaces relatively wider than in 

 longicollis. Beneath very sparsely punctate, the punctures rather coarse on the 

 sterna, but quite minute on the abdomen. Length 2 mm. 



A single example, collected by Mr. Knaus at Cloudcroft, is all 

 that is known to me of this quite distinct species. It may be at 

 once known from either of our two previously described species by 

 its small size and finely striate elytra. In neither pallipennis nor 

 longicollis are the elytra truly striate, the rows of punctures merely 

 occupying at most very feebly defined grooves. 



Since writing the above, other examples have been seen, collected 

 by Barber and Schwarz at Las Vegas Hot Springs. Some of these 

 specimens are larger than the above measurement. 



BYRRHID^. 



Pedilopliorus subsetosus n. sp. — Broadly nearly evenly elliptical, 

 greenish-bronzed, shining, vestitute moderately plentiful but not dense, consist- 

 ing of subrecumbent pale hairs, numerously interspersed throughout with short 

 slightly coarser less inclined pale setae, which are rather inconspicuous, but 

 plainly evident in profile, especially on the elytral declivity. Antennfe black, 

 gradually clavate as usual, the seventh joint about as wide as long. Entire upper 

 surface uniformly punctate, the punctures a little sparser on the vertex, but else- 

 where separated by about their own diameters. Sides of prothorax straight,, 

 faintly sinuate at middle, angles acute. Entire lower surface including the legs 

 piceous, densely, quite coarsely puuctate; tarsi not lobed. Length 41 mm..; 

 width 2 4-5 mm.

This species by its non- lobed tarsi would be associated with aneo-
