U.S.G.S. locality 7120. " NE. i, NE. i sec. 7, T. 9 K, E. 80 W., east 

 of Lake, one-half mile east of Higho, North Park, Colorado. (A. L. 

 Beekly and H. Bassler.)" This is evidently Locality 54 of Bulletin 

 596, U.S.G.S., p. 63, and is in the Coalmont formation. This elytron 

 has the general form of the acorn weevils of the genus Balaninus, 

 and it is to be noted that species of Quercus occur in the Coalmont 

 formation. The elytron is more acute than in the 

 Florissant species, of very much later date, described 

 by Scudder.

Two elytra. U.S.G.S. 728T. " NE. |, NE. \ sec. 9, 

 T. 7 N., R. 81 W., west end of bluff 3 miles north- 

 west of Coalmont, North Park, Colorado. (A. L. 

 Beekly and H. Bassler.)" Collected August 21, 1911. 

 This is locality 73 in the Coalmont formation, 



recorded on p. 65, Bull. 596, U.S.G.S. Glyptostrohus is recorded 



from the same place.

CALANDRITES (?) URSORUM, new species. 



Elytron 8.6 mm. long, 2 or very slightly over wide, with 

 sharp striae, and no punctures; the scutellum appears to have 

 large. 



Type. — University of Colorado, 5817. "Eocene; 

 south of Grizzly Creek, about 4 miles southwest of 

 Spicer, North Park, Colorado, July 31, 1911 (F. F. 

 Grout)." 



This looks something like C. hindsi, but is re- 

 markably long and narrow, with entirely different 

 sculpture. It presumably represents an extinct 

 genus, which can not be properly defined from the 

 elytra alone. The reference even to the blanket-genus 

 Calandrites is unsatisfactory. 



3. FOSSIL TSETSE FLIES. 

 Plate 55. 



The tsetse flies, the genus Glossina of Wiedemann, 

 constitute a very distinct group of the higher Dip- 

 tera, with rather numerous species. Although they 

 are generally referred' to the family Muscidae, which 

 contains the house fly and other common species, 

 they have so many peculiar characters that they may well be re- 

 garded as representing a distinct family. The formidable pro- 

 boscis, ensheathed in the palpi, is directed forward and is always 

 conspicuous. The wings, when at rest, are closed one over the other 

 in a manner observed in no other similar flies — a character which
