most parallel behind; margin behind the middle witha yellow spot. Elytra 
less convex at the base than in A. pulchella, with rows of large points, becom- 
ing strie behind the middle; interstices with a single series of small distant 
punctures; the ordinary yellow bands are more numerous, and those before the 
middle are confluent, so only the suture, a large humeral spot and a transverse 
spot one fourth way from the base, remain bronzed. The two posterior fascie 
are oblique ; the anterior one of them includes a small marginal spot; the tip is 
yellow. Beneath immaculate, bronzed, punctured. Varies with the anterior spot 
of the elytra large and confluent with the suture.

take great pleasure in dedicating this fine species, to the enterprising travel- 
ler to whom we owe its discovery. 
Body coppery-bronze, varied with bluish reflections, moderately stout and 
convex ; head strongly punctured, with three faint confluent elevated lines on 
the front, labrum green ; thorax cribrate, more than twice as broad as long, nar- 
rowed in front, very strongly rounded on the sides, narrowed a little towards 
the posterior angles, which are rectangular and sharp. Elytra with rows of 
large points, and with numerous deep impressed subconfluent spaces, which are 
opake, densely punctured and finely pubescent; tip entire. Legs green bron- 
zed, knees, tip of the tibiew, and tarsi steel blue. ‘Tip of the abdomen of the 
male very slightly truncate; of the female rounded.

This species is tolerably abundant in every part of Missouri Territory. It is 
closely allied to P. morio Germ. Zeitsch. 4, 85, but the elytral striz are not so 
deep, and the interstices are but very slightly convex. Head strongly punctur- 
ed. Thorax longer than wide, somewhat narrowed in front, slightly rounded on 
the sides, which are strongly margined ; disc moderately punctured, sides very 
densely punctured, scarcely impressed towards the anterior angles, posterior 
angles slightly diverging. Elytra as wide as the thorax, strie punctured, not 
deeply impressed, intertices scarcely convex, finely and irregularly punctured.

Among those brought by Dr. Woodhouse is a variety, in which the yellow tip 
of the elytrais much larger, inclosing a black spot.
