CETONIIN^E 359 



Body oblong, very depressed, black, opaculate above, shining be- 

 neath; erect hairs of the upper surface rather sparse but very long 

 and conspicuous, cinereous, about a fifth as long as the width of the 

 prothorax, rather easily broken or removed; head opaculate, with 

 rather small, deep and close but discrete punctures, flat above, deeply 

 impressed at each side over the antennae, the anterior slope steep and 

 abrupt, its upper line well denned, the surface slightly prominent 

 longitudinally at the middle but not on the very strongly reflexed 

 clypeus; prothorax depressed, one-half wider than long, widest 

 perhaps somewhat behind the middle, the sides feebly arcuate, 

 slightly sinuate at the hind angles; surface distinctly impressed 

 along the median line, having coarse, moderately deep, well separated 

 punctures; basal smooth angles very moderate, the oblique line 

 separating them from the general surface scarcely at all impressed 

 or otherwise traceable, except by contrast of lustre; elytra scarcely 

 one-half longer than wide, very feebly cuneiform, only a fourth or 

 fifth wider than the prothorax, the disk very flat, with the longi- 

 tudinal impressed lines of knochi, the areolse opaque, moderate in 

 size, broadly oval, not dense, very shallow and completely closed 

 behind or entire in outline; flanks abruptly descending but without 

 tumid upper line, coarsely, deeply and densely punctate; pygidium 

 convex and with the usual areolae; hind tarsi compressed but not 

 tapering, three-fourths as long as the tibiae. Length 10.8-12.0 mm.; 

 width 4.5-5.2 mm. New Mexico (Magdalena) and Texas. Four 



examples crinitus Lee. 



Clypeus no wider than the front, strongly reflexed as usual 21 



21 Body somewhat as in crinitus and strongly depressed but a little 

 larger and stouter, deep black, rather more shining above than in 

 crinitus, the sparse erect hairs almost similar, not quite so long but 

 conspicuous, longer and shorter intermingled and easily lost or 

 broken; head not so flat above, with stronger, deeper, very close-set 

 punctures and but very slightly impressed at the sides, the anterior 

 slope very steep, rather abruptly but not prominently delimited 

 along a transversely arcuate, strongly convex line, which is much less 

 abruptly defined than in knochi; prothorax nearly similar in form, 

 somewhat convex, feebly impressed along the median line, generally 

 widest evidently behind the middle and with coarse, rather deep and 

 well separated punctures; basal angles rather more depressed below 

 the general surface than in crinitus; scutellum with few areolae; elytra 

 subparallel, broader than in the preceding, a third to fourth wider 

 than the prothorax, much longer than wide, the longitudinal im- 

 pressed lines very feeble and indefinite, the disk nearly fiat, the 

 opaque areolae and abruptly deflexed, punctate flanks nearly as in 

 the preceding; opaque pygidium with well separated areolae, polished 

 and sparsely punctulate apically; hind tarsi nearly similar. Length 

 9.7-13.0 mm.; width 4.2-5.7 mm. Washington State, Idaho (Coeur 



d'Alene) and Utah. Abundant pugetanus n. sp. 



Body smaller, narrower and less depressed, black or piceous-black, 

 slightly shining above, more so beneath, the sparse erect hairs always 

 very small and inconspicuous; head strongly flattened above, with
