sparsely punctulate mediallv. Length 6.=; mm. ; width 2.68 mm. 

 Arizona (Riverside), — H. F. Wickham libertus n. sp. 



Elytra oval, distinctly wider than the prothorax, where the basal lobe 

 is strong and evenly rounded 1 1 



11' — Body elongate-oval, strongly convex, polished, dark castaneous, 

 the under surface dark, the legs paler, rufous ; head rather finely 

 but perforately and not very closely punctate, the punctures close 

 but not crowded, the epistoma arcuato-truncate, the sides strongly 

 converging, evenly and only moderately arcuate ; prothorax two- 

 thirds wider than long, the evenly sinuate apex four-fifths as wide 

 as the base, widest slightly behind the middle, the sides very 

 evenly and rather strongly arcuate throughout, the basal angles 

 right and not rounded, the punctures rather small but deep and 

 separated by from two to three times their diameters, becoming 

 obsolete along the basal lobe and rather abruptly coarse, confluent 

 and forming longitudinal folds laterally, without median im- 

 punctate line, the surface broadly impressed toward the middle at 

 base ; scutellum small, transverse ; elytra oval, gradually narrowed, 

 with evenly arcuate sides, to the acutely ogival apex in apical 

 half, less than one-half longer than wide and a fifth wider than 

 the prothorax, the sides strongly arcuate, the humeri not exposed, 

 the punctures fine, becoming coarse laterally, close-set in rather 

 uneven and unimpressed series, the interstitial punctures fine, 

 sparse, confused near the suture but frequently forming very 

 uneven single series elsewhere ; abdomen verv minutely, sparsely 

 punctate medially. Length 5.S mm.; width 2.4 mm. Arizona 

 (Winslow), — H. F. Wickham discretus Csy. 



Body stouter, oval, convex, polished, dark rufous, the under surface and 

 legs paler; head rather finely but very closely, substrigosely punc- 

 tate, the sides moderately converging and strongly, evenlv arcuate, 

 the apical margin broadly and feebly arcuate ; prothorax three- 

 fifths wider than long, nearly as in discretus^ except that the 

 sides are parallel in basal two-fifths, becoming subsinuate toward 

 base with the angles right and not rounded, mcKleralelv converg- 

 ing and straight toward apex, the punctures rather coarse, deep 

 and close-set, becoming sparse or obsolete along the basal margin 

 except at the sides, where thev are rather abruptlv coarse and 

 longitudinally confluent ; scutellum slightly larger, transverse ; 

 elytra as in discretus but more abruptly arcuately narrowed in only 

 apical two-fifths to the more obtusely ogival tip, between two and 

 three times as long as the prothorax and nearly a fifth wider, the 

 sides strongly arcuate, the punctures stronger, coarse laterally, 

 arranged in rather irregular unimpressed series, those of the inter- 

 vals less sparse, more broadly confused and larger than in dis- 

 cretus^ being about two-thirds as large as the serial punctures ; 

 abdomen rather finely but strongly, much more closelv and con- 

 spicuously punctured medially than in discretus. Length 6.0 

 mm.; width 2.8 mm. Arizona (near Benson), — G. W. Dunn.
