324 Mr. T. D. A. Cockerell — Descriptions and 



position of the leg the one spur visible appears to be on tlie 

 middle tibia of the left side, but from the pectination of the 

 spur I suspect that it is really the right posterior leg twisted 

 under the body); hair of legs dark fuscous; tongue with 

 copious long hair, and extending more than 1360 fi beyond 

 maxillae ; maxillae extending about 3230 fi beyond head ; 

 width of mouth-parts at base (where they leave the head) 

 about 1020 ii. 



Venation normal both in anterior and posterior wings 

 (including the very oblique t.-m. of the latter), except that the 

 first r. n. reaches the second s.m. near the beginning of its 

 last third instead of at the middle. The following wing- 

 measurements are in p, : — 



Length of marginal cell ] 760 



first diseoidal cell 2600 



First t.-c. to insertion of first r. n 510 



Insertion of first r. n. to second t.-c 255 



Third s.rn. on marginal 408 



Lower side of third s.m 510 



Length of third s.m. in middle 045 



Marginal cell beyond third s.m. (measured along its 



lower margin) 705 



The b. n. meets t.-m., the upper part of which is bowed 

 outwardly. 



Ilab. Florissant ; fossil in the Miocene shales, Station 13 B 

 {Melford Smith, 1908). 



This is the first genuine fossil Anthophora; the A. pffbssa, 

 lleydcn, from Rott, exhibited no wings, and cannot be re- 

 ferred with certainty to any particular genus. 



Calyptapisflorissantensis, Ckll., 1906. 



This genus and species were based on an imperfect specimen 

 obtained by Scudder, and were referred to the Eucerine 

 Anthophoridae. A very good example collected in the 



Miocene shales at Florissant in 1908 (Station 13 B, IV. P. 

 Cockerell) enables me to determine that it is in fact a member 

 of the Bombidaj very close to Bombus in most respects, but 

 differing in the form of the third submarginal cell and in the 

 somewhat less specialized second submarginal. 



It is stout-bodied, with hairy legs, quite as in Bombus; 

 lead and thorax black; abdomen rather pale reddish, the 

 junctions of the segments marked by moderately broad light 

 bands; the abdomen is not noticeably hairy. The hind 

 1 asitarsus is flattened and quadrate, broadly emarginate
