NORTH AMERICAN COLEOPTERA. 9 



When the leaves of tlie hiinenre are closed the apices are contigu- 

 ous, but the joints at middle are separated. 



The description of the female is taken from a perfect specimen in 

 the LeConte cabinet, the one originally described has been in my 

 possession since he received the other. 



The male specimens have brownish or yellowish-broAvn elytra, they 

 may possibly be somewhat immature, although I suspect they are 

 never so dark m color as fimbriata and Behrensii. 



For the specimens in my cabinet I am indebted to Mr. Henry 

 Edwards, who collected them Nov. 3, 1866, near Nevada City, Cal., 

 drowned in a small stream of water. 



P. L'lkei n. sp.— Oblong-oval, convex, dorsum depressed, surface siiining, 

 margin fimbriate and body clothed with reddish-yellow hair. Head piceous, 

 clypeal deeply oval emarginate, ante-ocular processes auriculate (not triangular 

 and acute). Thorax piceous, a paler space at the sides, more than twice as wide 

 at middle, as long, widest at middle, very strongly arcuately narrowed in front, 

 slightly narrowed to the basal angles, which are distinct, but rounded, disc retuse 

 (ratlier abruptly declivous) in front, a transverse obtuse elevation at middle, 

 behind which the disc is slightly concave, surface sparsely finely punctate, a 

 little more coarsely toward the sides. Elytra pale castaueous, sutural stria 

 deep, the interval convex and wider behind, geminate strife deeply impressed 

 and punctured, the intervals sparsely punctate, not rugose. Legs castaueous. 

 Length .96 inch ; 24 ram. 



Male. — First three joints of antennae as in hirticollis, fouith joint 

 short, with a slight prolongation, joints four to eleven 

 forming an elongate club as in hirticollis. 



Of this species I have seen but one specimen. It 

 is, therefore, not possible to say whether the paler 

 elytra are due to immaturity or represent the flill color. 



It gives me pleasure to dedicate this splendid species to my friend, 

 Henry LJlke, of Washington, whose name has often been mentioned 

 in our writings as a synonym for kindness and lil)erality. 



Collected in Utah. Remarkable as the first species known outside 

 of the California fauna. 



P. Staff Schaufuss. — Oval, slightly ohlong, convex, dorsum scarcely de- 

 pressed, head and thorax piceous, elytra pale chestuut-brown, beneath and legs 

 brownish, the margin fimbriate and clothed beneath with pale brown hair. Cly- 

 peal horn deeply emarginate, very little narrower at hase, vertical horn .short, 

 conical ; ante-ocular processes auriculate. Thorax more thau twice as wide as
