246 AMERICAN COLEOPTERA. 



Described from a single specimen collected by Townsend and 

 bearing label "So. Fork Eagle Creek, White Mts., 8000 ft." 



The type is a male, having the spur of anterior tibia slender and 

 rather strongly evenly curved ; the shorter spur of the middle tibia 

 with the extreme apex abruptly bent inward. Plutonicus i-esembles 

 quite closely pectoralis in the slightly dull elytra, but the latter 

 belongs to a different section by the equal tibial spinules. By 

 Horn's table it would fall near terminalis, which is a smaller species, 

 with non-tuberculate head and pale elytra! apex. 



Apliodius Iongitar!>iis u. sp. — Form rather narrow, parallel, not very 

 strongly convex ; liead and prothorax piceous, front and sides of head and sides 

 of thorax paler; elytra pale yellowish-testaceous, without markings; beneath 

 rufopiceous, legs testaceous. Head moderately convex, frontal tubercles evident, 

 connected by a raised line; surface in front of the raised line coarsely verrucose 

 and with short erect hairs ; occiput coarsely punctate, sometimes rugose ; clypeus 

 rather deeply emarginate, sides rounded. Prothorax moderately transverse, a 

 little narrowed in front, sides sparsely fimbriate, base evenly arcuate with fine 

 marginal line, hind angles indistinct, sides moderately arcuate; surface witli 

 coarse punctures, which are nearly uniform in size but somewhat irregular in 

 distribution, rather sparse at middle, becoming moderately dense at sides. Elytra 

 two-fifths longer than wide, a little wider than the thorax and two and two- 

 third times as long, sides nearly parallel, humeral angles narrowly rounded ; 

 strije moderate, finely punctured, intervals slightly convex, each with a series 

 of fine sparsely placed punctures each side, closely adjacent to the striae. Meso- 

 sternum opaque, not carinate; metasternum and abdomen sparsely punctate. 

 Femora with a few fine punctures. Anterior tibia? smooth in front, moderately 

 strongly tridentate, spur slender, feebly curved and a little longer than the first 

 tarsal joint. Tarsi very slender and elongate, basal joint of hind tarsus equal to 

 the next two; long spur of both middle and hind tibife evidently shorter than 

 the first tarsal joint. Length 3i-4 mm. 



El Paso, Texas ; Aweme, Manitoba (C H. Rowe). 



The El Paso examples are to be regarded as types. The Mani- 

 toba specimens are slightly larger, the thorax a trifle wider, the 

 elytral striae more strongly punctured. The differences are, I think, 

 of little moment, the wider thorax perhaps indicating the male. 

 The spinules of the middle and hind tibiae are very unequal, the 

 longer and shorter alternating with considerable regularity. This 

 species seems most closely related to scabriceps, with which indeed 

 it has been confused by LeConte, a single specimen being so placed 

 in the collection. The very long tarsi with relatively shorter basal 

 joint will at once enable it to be separated.
