one-lialf wider than loiifc. broadly rouinU'd on the sides, apex widely but less 

 strontrly constricted, tubercles acute, dorsnl channel entire, narrowed and more 

 superficial anteriorly, disc densely punctured and scaly, scales elongate, iiiliCorni. 

 four s]>ots of pale scales in a transver.se line innnediately in front of the lateral 

 tubercles, another row of three spots behind the apical niarjrin. Elytra two-fifths 

 wider at the base than the prothorax at its base, scarcely wider than lonfi, rather 

 stroufily narrowed posteriorly, strise in)i)ressed with a row of scales concealing 

 more or less the rather large punctures. intersi)aces convex, alternately wider and 

 a little more convex, surface mottled in nearly ecjual proportion with pale and 

 dark scales. Legs rather stout, densely clothed with scale-like i)ul>esceiice, tibige 

 widened from the base towards the ajtex. middle and posterior with a broad tri- 

 angular tooth, acutely eniarginate above the a])ex, tarsi moderately stout, the 

 fourth joint scarcely longei' than the two j)receditig two joints together, third 

 not very broadly bilobed ; pygidiuin coarsely and not very densely j)unctured 

 Length 3.0-3.5 mm. ; 0.12-0.14 inch. 



%. Fifth ventral segment feebly impressed, middle and posterior tibise ungu 

 iculatc at the a])ex.

 zona, Montana. 



Xuniorous specimens are before me. Differs somewhat in size and 

 apj)earance acttonling to the preponderating color of the scales. A 

 sj)ecimen in my coll. from Montana has the interspaces more flattened 

 and less iiiuMpial ; punctures more distinct. Gyllenhall's description* 

 applies rather to arf-p/ia/ns than to the jjresent species. 



A. accpliallis Say. PI. xii, figs. 9. 9a iind 96. — Broadly oval, blackish, legs 

 rufopiceous, above clothed with i)ale. ashy-gray or yellowish .scales, unicolorous 

 or mottled in varying proportions with dark brown ; scales coarse pilifoi-m on the 

 prothorax, smaller and oval, or elongate oval on the elytra, underside densely 

 clothed with large, oval, ashy-gray s(Mles. Beak rather long, stout, cylindrical, 

 and entirely scaly in the male, more slender, conspicuously tapering and shining 

 in its apical half; in the female, antennte inserted at the middle ( % ), or two- 

 fifths from the base ( 9), first and second joints of funicle elongate, joints three 

 and four equal, not longer than wide, joints 5-7 short, gradually wider, club 

 ovoidal, subacuminate ; upper margin of eye not elevated above the level of the 

 front, the latter flattened or longitudinally impressed; prothorax convex, more 

 than one-half wider than long, about twice as wide at the base than at the apex, 

 hind angles rectangular, sides regularly rounded, strongly, but not broadly con- 

 stricted at the apex, dorsal sulcus distinct, nmre deeply impressed at the base, 

 nearly obsolete in front, lateral tubercles small, inconspicuous, a fovea-like im- 

 pression in front of each tubercle; surface den.sely punctured, punctures mod- 

 erately large. Elytra about one-fifth wider at the base than the prothorax. 

 scarcely as long as wide and markedly narrowed posteriorly, stria; wide, im- 

 pressed. es])ecially at the base. i)unctures.not very evident, small: intersjiaces 

 equal, flattened ; pygidiuni convex, coarsely punctured. Legs moderately stout,
