Vegas is a little larger than the Fort Wingate specimens 4.9 by 

 3.0 mm., with more coarsely and deeply impressed three dorsal 

 striae, the fourth and fifth being feebly impressed series of indefinite 

 punctures and each more than a third as long as the elytra, the 

 sutural finer and more punctulate from basal third to apical sixth, 

 the postero-lateral lobes of the black plaga much thinner, strongly 

 diverging and more parallel-sided than in any other, the propygidial 

 punctures coarse and sparse, those of the pygidium strong, becoming 

 gradually fine in about apical half and the mesosternum is nearly 

 as in quadratulus and sarcinatus; it may be named bilobatus (n. sp.). 

 The specimen from Cimarron, New Mexico, is also larger than 

 quadratulus and more broadly oval, the striation as in the latter 

 species, the very sparse pygidial punctures also similar, though finer, 

 but the mesosternum is as in militaris and tunicatus. It also prob- 

 ably represents a distinct species. 



The species described by me under the name Ulster Virginia 

 (Ann. N. Y. Acad. Sci., VII, 1894, p. 541) proves to be the same as 

 obtusatus Harris (Trans. Hart. Nat. Hist. Soc., 1837, p. 76). It is 

 very much stouter than interruptus Beauv., with the pygidial 

 punctures much coarser and denser, and it is one of the most 

 distinctly characterized species of the group; its suppression as a 

 synonym of interruptus must be condemned as a careless oversight, 

 to say the leasr. Obtusatus is abundant from Virginia northward 

 to New York and Massachusetts.

Within the last few days, Mr. Carnochan, on looking over my 

 collection, stated that I had correctly determined his Phelister frosti, 

 but that my sayi Carn. (ante p. 229) was not that form, nor closely 

 allied thereto. It is our smallest species of the genus by far, and 

 it gives me pleasure to name it carnochani (nom. nov.). 



In drawing up the table of Phelister species (1. c.), I gave but little 

 attention to the striation of the inflexed sides of the elytra, which 

 however should be considered carefully in a more general mono- 

 graph of the genus. In subrotundus there is but a single very coarse 

 entire sulcus. In vernus there is the same coarse sulcus, but below 

 it appears a short feeble stria. In simplex there are two fine entire 

 lines, but, with greater amplification, these prove to be simply the
