302 MEMOIRS ON THE COLEOPTERA 



broadly rounded and wholly obliterated; apex broadly, feebly 

 sinuate, strongly beaded laterally, with rather well defined and sub- 

 acute angles and very much wider than the base, which is feebly 

 sinuate and unmargined medially, beaded about the hind angles and 

 thence along the sides to the apex; surface smooth, narrowly reflexed 

 at the sides, the gutter ending posteriorly at the flattened densely 

 punctulate latero-basal surface; fovese large, closely punctulate, 

 gradually impressed to the rather punctiform bottom; fine punctures 

 extending across the median part near the base; stria very fine, a 

 little stronger basally; elytra but little more than two-fifths longer 

 than wide, very slightly (cf) or distinctly (9) wider than the pro- 

 thorax, the sides parallel and broadly, feebly arcuate, circularly 

 rounded in apical two-fifths, the sinus feeble but evident; striae fine, 

 feebly impressed, the scutellar long; intervals nearly flat, the discal 

 puncture strong, at apical third; anterior tarsi stout, tapering from 

 base to tip, the posterior rather stout, filiform, the spines of the 

 articular apices long, forming a corona; first joint as long as the next 

 two but much shorter than the fifth, which is swollen at apex, the 

 claws rather long, moderately slender and strongly, evenly arcuate. 

 Length (cf 9 ) 14.8-15.0 mm.; width 5.5-6.0 mm. Arizona (Will- 

 cox). Three examples brunnea n. sp. 



Form less stout, more cuneiform, convex, shining, darker in color, the 

 entire upper surface and lower surface of the head and prothorax 

 black, the under surface of the hind body and the legs testaceous; 

 head very moderate in size, barely three-fourths as wide as the pro- 

 thorax, the eyes, mandibles and antennae nearly as in the preceding; 

 mentum transversely concave anteriorly, the concavity interrupted 

 at the middle; prothorax twice as wide as long, nearly as in the 

 preceding, except that the arcuate sides are more strongly converging 

 posteriorly, the base feebly beaded entirely across the width, the 

 surface near the very broadly rounded hind angles more reflexed 

 and impunctate and the foveae deep, more punctiform and impunctate, 

 but with radiating rugae, the apical angles more blunt; elytra nearly 

 one-half longer than wide and fully a fifth wider than the prothorax, 

 not parallel as in the two preceding but somewhat dilated behind 

 the middle, the sinus rather broad, feeble though very evident, 

 otherwise nearly as in brunnea; hind tarsi nearly similar. Length 

 (cf ) 12.5 mm.; width 5.2 mm. A single specimen received recently 

 without label but supposed to be from Arizona mentalis n. sp. 



The descriptions seem to agree in stating that the head in capitata 

 is virtually as wide as the prothorax, which is said also by LeConte 

 of his erro, but while the prothorax in capitata, as noted from the 

 figure in the "Biologia," is not very transverse, not even twice as 

 wide as long and with the basal angles not extremely rounded, this 

 part in erro is said by LeConte to be nearly three times as wide as 

 long probably an exaggeration, with the hind angles broadly 

 rounded. It is rather more than possible, therefore, that Cratocara
