324 CASEY 



widest rather behind the middle, the sides subevenly, rather 

 strongly arcuate but becoming somewhat abruptly converging 

 and straight near the basal angles, the punctures rather small, 

 sparse and submuricate inedially, where there is a very fine, faint 

 median raised line not extending to base or apex, rather coarse, 

 subcontiguous and scabrous laterally, the lateral margin very fine ; 

 elytra oval, fully one-half longer than wide, rather more than three 

 times as long as the prothorax and slightly wider, gradually and 

 not very obtusely rounded behind, parallel, the sides broadly 

 arcuate, widest near the middle, the humeri not at all exposed at 

 base, the punctures rather coarse, especially toward base, some- 

 what close-set in subeven and unimpressed series, the interstitial 

 series regular but with rather less coarse and widely spaced punc- 

 tures; abdomen polished, feebly rugulose and rather sparsely 

 punctulate. Length 4.8 mm.; width 2.15 mm. New Mexico 

 (Albuquerque), — H. F. Wickham pavida n. sp. 



Body oval, convex, stouter, the head with moderate, scarcely scabrous 

 and rather distinctly separated punctures ; prothorax much shorter 

 and more transverse, twice as wide as long, distinctly narrowed 

 and sinuate at apex, the sides subevenly and rather strongly 

 arcuate, becoming straight or subsinuate for a much shorter dis- 

 tance immediately before the basal angles; surface with similar 

 trace of a fine partial elevated median line, the punctures very 

 fine, rather sparse and feeble mediallv, gradually coarse laterally, 

 becoming almost contiguous and scabrous near the sides, which 

 are much more broadly reflexed than in either the preceding or 

 following species; elytra two-fifths longer than wide, fully three 

 and one- half times as long as the prothorax and distinctly wider, 

 the apex gradually and obtusely ogival, the sides arcuate, the 

 humeri slightly exposed at base, the series unimpressed, some- 

 what uneven, composed of close-set punctures which are very 

 feeble and not very large, flexed outwardly toward base, with 

 gradually much coarser and deeper punctures, the interstitial pimc- 

 tures forming very irregular single series, smaller in size and more 

 widely separated ; abdomen very convex, finely, sparsely punc- 

 tate. Length 5.3 mm. ; width 2.4 mm. Arizona (Winslow), — 

 H. F. Wickham ovalis n. sp. 



Body elongate-oval, convex, much narrower than in the two 2:)receding; 

 head rather closely and coarsely, muricately punctate ; prothorax 

 four-fifths wider than long, but slightly narrowed though strongly 

 sinuate at apex, the sides subparallel, almost evenlv and very 

 moderately arcuate, much less rounded than in the two preceding 

 species, the lateral edges only very finely reflexed but distinctly 

 and unevenly serrulate ; punctures rather small but distinct, sub- 

 muricate and well separated, becoming gradually larger and more 

 rugose laterally and very coarse and closely scabrous near the 

 sides ; elytra very elongate, three-fifths longer than wide, three 

 and three-fourths times longer than the prothorax and slightly 

 wider, gradually obtuse and subparabolic at tip, widest at about
