base, at the middle almost one-half wider than the prothorax, the 

 surface finely, closely punctate, more coarsely and densely so 

 laterally, without distinct impressed lines, the punctures confused 

 throughout, the sutural angles very acute but simple ; abdomen 

 finely rugulose, finely but closely punctured medially. Length 

 8,5 mm.; width 3.7 mm. Kansas jucundum n. sp. 



Form more narrowly elongate-oval, strongly convex 12 



12 — Body strongly shining, piceous-black with distinct itneous lustre, 

 each puncture bearing a small but very evident cinereous hair ; 

 head not very coarsely but closely, evenly punctured, the punc- 

 tures separated by about their own widths near the middle, the 

 antennae moderately slender ; prothorax relatively small, the apex 

 but little more than two-thirds as wide as the base, with the angles 

 rather strongly deflexed though very acute and anteriorly promi- 

 nent when viewed subanteriorly, the basal right and not prominent, 

 the sides evenly and distinctly arcuate, the surface strongly but 

 only moderately coarsely, rather closely punctate, the punctures 

 separated by nearly twice their own widths medially, becoming 

 but slightly larger but deep and close though not at all crowded 

 laterally ; scutellum moderate ; elytra oblong, rather rapidly and 

 arcuately narrowed in about apical third, the sides moderately arcu- 

 ate to the rounded humeri, which are rather widely exposed at base, 

 at the middle fully one-half wider than the prothorax, the punc- 

 tures very fine but deep, sparse, becoming larger but shallow and 

 still well separated laterally, with but the feeblest evidences of 

 larger seriate punctuation suturally, the impressed lines almost 

 wanting, slightly evident apically near the suture, the sutural angles 

 very acute but simple ; abdomen feebly rugulose, rather finely, 

 not very sparsely and strongly punctured medially. Length 9.8 

 mm.; width 4.6 mm. Utah (St. George), — H. F. Wickham. 



parvicolle n. sp. 



Body moderately shining, the upper surface with strong bronzy lustre, 

 the under surface with scarcely any metallic reflection, each punc- 

 ture bearing an extremely minute and wholly inconspicuous hair ; 

 head closely, rather coarsely, deeply punctate, more finely an- 

 teriorly ; prothorax long, well developed, scarcely a fifth wider 

 than long, the apex three-fourths as wide as the base, with the 

 angles not much deflexed, very acute and anteriorly prominent, 

 the basal slightly acute and prominent, the sides evenly but rather 

 feebly arcuate ; surface not coarsely but deeply, rather closely 

 punctate, the punctures separated by rather more than twice their 

 own widths medially, becoming only moderately coarse but deep 

 and very close-set laterally ; scutellum well developed, transverse, 

 rounded, flat and impunctate ; elytra gradually acute and with 

 moderately arcuate sides in nearly apical two-fifths, the sides 

 broadly arcuate, more rounding at base to the obtuse humeri, 

 which are very narrowly exposed at base, the surface without 

 trace of impressed lines except one along the suture toward tip.
