strongly reflexed bead; median line fine and very feeble. Elytra oblong, 

 scarcely more tban ^,j longer tban wide, fully twice as wide as the prothorax, 

 only slightly wider at apical third than at base, the sides very feebly arcuate 

 and very narrowly reflexed; disk moderately convex, with scarcely impressed 

 even series of extremely fine punctures, Avhich become stronger toward base, 

 the intervals there becoming transversely broken by arcuate impressed lines 

 as in peregrinator, the three series of interstitial asperate punctules very feeble; 

 marginal punctures visible only toward base, the submarginal aspei-ate punc- 

 tures rather widely separated and uneven. Legs moderate in length and quite 

 slender. Length 16.5 mm. ; width 7.5 mm. 



Arizona. 



The anterior tarsi of the male haA'e the first three joints rather 

 feebly dilated and densely pubescent beneath, the pad of the first 

 joint small and apical; the hind trochanters and intermediate legs 

 are not modified. Parviceps also belongs near peregrinator, and 

 greatly resembles the preceding species at first glance ; it how- 

 ever differs in sculpture, structure of the labrum, in its much 

 deeper epistomal impressions, less transverse prothorax with less 

 rounded side angles, shorter and broader elytra and in several 

 other minor characters. 



C moiiticola n. sp — Ovoidal, moderately stout, rather feebly convex, 

 deep black throughout, without metallic lustre at any part, the surface 

 polished, the elytra becoming somewhat alutaceous laterally and toward apex. 

 Head well developed, a little more than }'2 as wide as the prothorax, convex, 

 minutely and sparsely punctate, rugose laterally behind the epistomal impres- 

 sions, which are narrow and deep; labrum impressed in the middle, the apex 

 angularly but feebly emarginate throughout the width; antennse rather short, 

 the outer joints glabrous on the compressed sides. Prothorax transverse, not 

 quite twice as wide as long, widest near apical third, the sides evenly arcuate 

 anteriorly, becoming more convergent and nearly straight behind, the basal 

 angles rounded and prominent jDOsteriorly; base transverse and slightly nar- 

 rower than the apex ; disk very feebly convex, broadly impressed sublaterally 

 toward base, the sides rather narrowly explanato-reflexed, the marginal bead 

 rather thin and strongly reflexed; surface minutely, sparsely punctate, the 

 punctures becoming rapidly larger and transversely coalescent or rugose toward 

 the sides; median line very flne. Elytra oval, scarcely ,^4 longer than v^ide, 

 % wider than the prothorax, wider behind the middle than at base, the sides 

 rather strongly arcuate; disk very moderately convex, with impunctate striae 

 which become gradually strongly impressed toward the sides, but almost com- 

 pletely effaced toward the suture, the intervals convex laterally, frequently 

 interrupted by transverse arcuate lines enclosing asperate tubercles, both 

 becoming very pronounced toward the sides and apex but wholly obsolete 

 toward the suture, where the intervals are flat and entire; three interstitial 

 series traceable by fine but slightly more pronounced and remotely separated
