cessor, each di^thictly longer than broad. Palj)i elono-ate, 

 white, the terminal joint slender and elongate. Head 

 nineh smaller than the thorax, very shining black ; the 

 mandibles red; the antennal tubercles reddish; a single 

 fine puncture on the front margin of the clypeus, a depres- 

 sion inside the tubercles, and behind this two punctures 

 on each side, and a few punctures on oach side of the 

 vertex. Thorax very shining, black, about as long as 

 broad, transversely convex, not narrowed behind, with an 

 irregular row of four or five coarse punctures on each side 

 the middle ; with four or five others outside these, some 

 fine punctures on the front margin, and with a few fine 

 obsolete pmictures scattered over the surface. Scutellum 

 black, not ])unctured. Elytra slightly longer than the 

 thorax, shining red, deeply and very coarsely punctured, 

 the punctures not dense. Hind body short, o])aque, the 

 segments obscurely punctured, the three or four basal 

 ones with ashy pubescence on each side ; the 7th segment 

 ■white, Avith a black patch on the middle. Legs rather 

 stout, Avhite. The sternum, with the coxjfi and under 

 face of hind body, reddish. 



In the male the ventral plate of the 7tli segment has the 

 middle part greatly produced, so as to form a large tongue- 

 like process ; it is separated by a deep notch from the 

 lateral portion, and is finely punctured in the middle ; 

 that of the 8th segment forms part of the intromittent 

 organ ; it is polished and quite smooth, from beyond the 

 middle gradually narrowed to the extremity, where it forms 

 a sharp spine. 



Amazons; a single male, Avithout sjiccial locality. 



This very remarkable species is allied to the 1*. er/ens, 

 though extremely different from it in appearance. I should 

 suppose the Columbian P. crassicollis, Er., may be an 

 allied species. 



Q^DODACTYLUS. 



The tAvo species here described are only referred Avit' 

 doubt to the genus (Edodactijlus, hitherto representeu 

 only by CE. fascobrnnnens, from Chili. They are re- 

 markal)le by the elongate anterior coxa% and the great 

 development of the side ])ieces of the thorax, and may be 

 considered the Austro-Columl)ian representatives of the 

 Arctogival and Austi-alian Procirrns, to Avliich genus the 

 Chilian species approaches in facies more nearly than do
