are two stout tooth-like ; pines. Spur long, curved, slender, blunt at apex. 

 Middle tibiae more slender, a little curved, somewhat expanded and sinuate 

 towards the apex, spinose externally, spurs slender, the posterior one longer. 

 Hind tibiae similar. Length 3.75 mm., width. 1.90 mm.

This species is described from eight specimens from Southern 

 Pines, N. C. (type locality), collected with others under decay- 

 ing fungus, Nov. 23, 1911, by Rev. A. H. Manee, and one spec- 

 imen from Pensacola, Fla., collected Dec. .">, 1X7!) by E- A. 

 Schwarz. These show some variation in color, as expressed by 

 the description. The pubescence is easily abraded, some indi- 

 viduals being nearly naked above. The species has been dis- 

 tributed as Perihalycra murrayi Horn, which differs in being 

 more coarsely punctured, especially on the pronotum, in the 

 stronger fimbriation of the margin, and especially by the tooth- 

 ing of the front tibiae. In P. murrayi the external prolongation 

 of the tibia forms a bidentate process, while in Carolina it is 

 produced into a single long tooth. The crenulation of the outer 

 margin of the fore tibia is more pronounced in murrayi and the 

 spines near the middle are differently spaced. It would be in- 

 teresting to know if the LeConte specimen from Georgia, men- 

 tioned by Dr. Horn in connection with the original description 

 of P. murrayi, may possibly be P. Carolina, since the two species 

 have a strikingly similar superficial resemblance and seem to be 

 absolutely congeneric in prosternal, antennal and other structural 

 characters. The insect described by Blatchley as Quadifrons 

 castaneus, from Florida, is very different in the structure of the 

 front tibiae which, from description, would seem more like those 

 of Thalycra. In Quadrifrons the labrum is said to be rounded 

 and not emarginate, while in both species of Perihalycra it is bi- 

 lobed. 



I am indebted to Mr. E. A. Schwarz for assistance in the way 

 of suggestions and in giving me access to the specimens of Per- 

 ihalycra and allied genera in the National Collection. 



Osmoderma montana, new species 



General form and luster similar to that of the same sex (female i of (>. 

 ercmicola, but smaller, relatively more slender and with a more aeneous tinge. 

 In comparison with a female O. errmii nln from Lone Rock, \Vis., which was 

 selected as representing a markedly northwestern locality, it is seen that 

 montana has a shorter clypeo-frpntal plate, the rugae of the central part of 

 which are transverse instead of concentric; the pronotum is slightly more
