tenebrosns. 

 Smaller species, not exceeding 3.5 mm. ; a superciliary ridge and sulcus generally 

 distinct. 

 Alternate elytral interstices more prominent, above setigerous-alteriiatlis. 

 Each elytral interstice with a row of setse. 



Interstices of equal width ; scape of anteniife of usual length. ..niontail lis. 

 Interstices of unequal width ; scape of anteniise short iiltorstitialis. 



J**- grypidioides n. sp.— Oblong, piceous; antennae, tibise and tarsi paler; 

 beak slightly longer than the thorax, slender and but little widened towards the 

 base, narrowed about the middle; tricarinate, coarsely punctured and sparsely 

 clothed with round scales, intermixed with transversely directed, scale-like pu- 

 bescense, separated from the front by a slight, transverse furrow. Antennse 

 slender. Head transverse, convex and rather densely clothed with round scales 

 having, like those of the rostrum, a slight pearly lustre. Thorax urn shaped, 

 one-half broader than long, widest behind the middle, strongly rounded at the 

 sides behind and feebly constricted at apex : base broadly rounded ; lobes feeble 

 leaving the eyes almost entirely uncovered in repose; surface finely and denselv 

 punctured, transversely impressed in front and densely covered with grayish 

 brown scales; median vitta narrow, obsolete about the middle, lateral vittfe 

 broader, bisinuate. Elytra one-fourth wider than the thorax at its widest, 

 slightly emarginate at base; humeri rounded, prominent; moderately convex 

 and parallel for two-thirds their length, gradually narrowed to and conjointlv 

 rounded at tip: strise fine, moderately impressed, with small, not very approxi- 

 mate punctures ; interstices broad, feebly convex, each with a row of setigerous 

 punctures; setfe .short, slender and inconspicuous; densely clothed with grayish 

 brown scales, indistinctly mottled with paler spots, especially along the sides; 

 .scutellum and humeral spots white. Beneath: thorax with large, superficial 

 punctures, densely scaly ; abdomen glabrous, or nearly so, punctures smaller, 

 setigerous. Legs with a few scattered scales, tibiae slender, incurved at tip and 

 distinctly denticulate along their inner margin, each denticle bearing a distinct 

 seta; tarsi fringed with long, slender hairs, fourth joint longer than the others 

 combined. Length 4.0-4.5 mm. ; .16-. 18 inch. 



% . Last ventral segment with triangular flattened space. 

 9 . Last ventral segment with a longitudinal groove at its distal 

 half, causing it to become narrowly emarginate. 



Has considerable resemblance to Grypidms hrnnneirodris. 

 Hab. — Kansas, Nevada, Texas, S. AVyoming.
