This very distinct species, because of the pecuHarities of its 

 thorax, should be confused with no other species in our fauna. 

 In my table, it should follow C. hubbardi Schwarz, the two in 

 their turn to follow C. concinnus Boh. It is, however, not closely 

 related to either. 



C. bohemanni Horn. This should be placed as a synonym of C. platalea 

 Say. As stated by Dr. E. A. Schwarz, Bohemann used the term " pone " 

 for " near " and not " behind " as interpreted by Dr. Horn. 



C. quadricollis Van Dyke. Two specimens from the Nat. Mus., col- 

 lected at Republic, Oregon, by Mr. A. W. Barber, have been seen. This 

 shows the northward distribution of the species, as was to be expected. 



C. ellipticollis Van Dyke. Six specimens from Arizona, mostly Winslow, 

 belonging to the Nat. Mus., have been seen. 



C. concinnus Boh. This should be reduced to a variety of C. impressi- 

 frons Boh. A review of the literature has convinced me that there is no 

 valid reason for retaining it apart. 



C. crenatus Horn. Specimens of this species have been taken in abund- 

 ance in various parts of California, from the so-called digger pine, Pinus 

 sabiniana Dougl. 



NOTES ON STRATEGUS MORMON. 



By Warren Knaus, McPherson, Kan. 



The writer first took this rare Scarabseid June, 1913, on ground 

 he had collected over at least once a season for almost a quarter 

 of a century. The two specimens were male and female from bur- 

 rows under horse droppings. The burrows are easily distin- 

 guishable, being about i }i inches in diameter, larger by a fourth 

 than the similar holes of Phanmis difformis in the same situa- 

 tion. Usually a pile of freshly turned sand at horse droppings in- 

 dicates a burrow, the larger Strategus mormon, the smaller the 

 Phanceus; but occasionally there is no sand heap or covering 

 around the larger. The hole either goes straight down or inclines 

 not over fifteen degrees and varies from four to twelve inches in 

 depth. My first two Strategus was taken on a perfectly bare 

 sand dune, probably fifty yards apart. 



In 191 5 I secured eight specimens on the dunes under horse 

 droppings a mile away from the locality of my first specimens. 

 They were five males and three females, coming from late in
