No. 501] THE FLORISSANT EXPEDITION OF 1908 bib 



published early in 1908 {Bull. Amer. Mus. Nat. Hist.) 

 was known only from the wings. A photograph of a 

 wing was sent to Dr. Needham, who wrote: " It is indeed 

 a most interesting fossil, another synthetic type. . . . 

 De Selys' Podagrion group of Agrioniiuv includes the 

 most primitive members of that subfamily, and this fossil 

 is more primitive in several characters than any living 

 forms." Very fortunately, a splendid specimen of 

 Phenacolestes parallelus was uncovered this year by Mr. 

 Geo. N. Eohwer. As the illustration shows, it is nearly 

 complete, lacking, however, the apex of the abdomen. 

 The wings are not so heavily clouded as in P. mirandus, 

 the type of the genus, and there are differences in the 

 venation. P. parallelus was originally described from 

 the apical half of a wing. 



Some Fossil Bees 

 In 1906 (Bull. Mus. Comp. Zool.) I described a bee's 

 wing found at Florissant by Scudder, regarding it as the 

 type of a new Anthophorid genus, Calyptapis. A very

fine example, showing the body, was found this year, and 

 from a close examination I am able to ascertain its true 

 position. It is not an Anthophorid at all, but is a genus 

 of Bombidae, in other words a bumble-bee. The genus is 

 valid, and gives the first indication of the former history
