WICKHAM: new MIOCENE COLEOPTERA from FLORISSANT. 429 



that the two authors, Beutenmueller and Cockerell, would have over- 

 looked so striking a difference as the spacing of the costae, which, in 

 N. surinameims, are about equidistant from each other and from the 

 suture as well, while the distance from the exterior costa to the margin 

 is relatively much less than in S. beutcnmurlleri. The last species 

 seems to have almost exactly the same arrangement of costae and 

 groove as the recent European S. tyrolensis but the punctuation is 

 finer and much better separated in the fossil. In this character it 

 closely approaches the recent North American S. novehoraccnsis. 

 The insect is named for Mr. William Beutenmueller of New York.

COCCINELLIDAE. 



Coccinell.^ florissantensis, sp. nov. 

 Plate 1, fig. 4. 



Form a little more elongate than in most of the recent North Ameri- 

 can species. Head in poor preservation, the outline broken. Pro- 

 thorax short, sides not very well preserved but evidently arcuate and 

 convergent anteriorly, apex much narrower than the base. Scutel- 

 lum minute. Elytra ^^■ithout distinguishable maculation, estriate, 

 outer edge margined but imperfect in the specimen. Upper surface 

 extremely minutely alutaceous as in many recent Coccinellidae. Legs 

 wanting. Length, 5.95 mm. 



Described from one specimen.
