Two specimens in the Carnegie Museum under the name Chelonychus longipes , one with a ‘‘Col.’’ label, the other labeled ‘‘Cal.’’, are probably syntypes . Dietz did not indicate the number of specimens he had in his series, but these account for all of the localities he listed: ‘‘Yreka, Cal. (Dr. Horn); Minnesota , Colorado (H. Ulke).’’ Description. Body ( Figs. 25–26 ): oval in dorsal view; length 1.6–2.1 mm ; width 0.8– 1.0 mm. Integument black, broadly visible between scales. Head : vertex with narrow scales, broader, slightly imbricated scales present beneath. Rostrum ( Fig. 25 ): evenly curved; proximal portion shallowly sulcate; long, narrow scales on extreme base replaced THE COLEOPTERISTS BULLETIN 56(1), 2002 119 Figs. 25–28.

Antenna : funiculus with 7 articles. Prothorax : pronotum with admixture of elongate, narrow, slightly curved, cinereus scales and broader, flattened, cinereous to infuscate scales. Elytra : rounded apically in dorsal view; striae narrow, punctures with minute, inconspicuous setae; interstriae with elongate, narrow, slightly curved, cinereous scales and slightly to distinctly broader, flattened, cinereous to infuscate scales. Pygidium : with slender, cinereous scales. Abdomen : sterna 1–4 with pallid scales laterally, with narrower scales medially; sternum 5 convex, with elongate, setiform scales medially. Legs : profemur with one small ventral tooth; protibia with inner margin prominent in basal 2/3, concave in apical 1/3; protibial uncus long, slender, slightly curved, acute; metatibia with inner margin slightly prominent in basal 2/3, slightly concave in apical 1/3, outer margin straight ( Fig. 29 ); metatibial mucro straight, oblique in lateral view, acute ( Fig. 29 ); tarsal claw with acute basal tooth ( Fig. 31 ). Male Genitalia ( Fig. 32 ): median lobe of aedeagus narrowed to bluntly rounded apex in dorsal view, broadly, evenly curved in lateral view; endophallus minutely denticulate. Specimens Examined.

Plant Associations. Label data indicate that adults of C. longipes have been collected on Artemesia ludoviciana Nutt. (Asteraceae) . Remarks. Specimens of C. longipes from McMurray, Alberta , are distinctly larger and more densely squamose than the types and have a smaller tooth on the profemur.
