Genus AMPHICYRTA Erichson. 



AMPHICYRTA INHiESA Scudder. 



Two specimens, not differing in size nor other appreciable detail 

 from Scudder's description and figure. 

 Cat. No. 59650, U.S.N.M. 



Genus BYRRHUS Linn^aeus. 



BYRRHUS ROMINGERI Scudder. 



One specimen, agreeing almost exactly with the original in size. 

 Cat. No. 59651, U.S.N.M. 



Genus ANTHAXIA Eschseholtz. 



ANTHAXIA EXHUMATA, new species. 

 Plate 23, figs. 4, 5, 6. 



Preserved in dorsal view. Form similar to that of the recent 

 A. seneogaster, but somewhat less obtuse posteriorly. Head broad 

 and short, anterior outline slightly concave. Antennge extending 

 about to the hind margin of the prothorax. Prothorax a little more 

 than twice as wide as long, sides prominent, the right showing the 

 squarish truncation, which is so well marked in A. seneogaster, anterior 

 margin arcuately, rather weakly lobed at middle, hind margin sinuate 

 each side. Elytra at humeri a Httle broader than the thoracic base, 

 tapering to apex, which is a little truncate. The entire upper sur- 

 face of the body shows the same type of sculpture as in ^. seneogaster — 

 a coarse reticulation (fig. 6). In the fossil these reticulations are 

 slightly larger on the prothorax than on the elytra and considerably 

 larger than on the head. Length, 7 mm.; of elytron, from humerus 

 to apex, 4.90 mm. Width of prothorax, 2.90 mm.; of one elytron 

 at middle, 1 .50 mm. 



Type.— €sit. No. 59642, U.S.N.M. 



One specimen. This insect goes well into the genus Anthaxia by 

 all the visible features. As far as can be told, it was not very unlike 

 the species with which it has been compared in the foregoing descrip- 

 tion, but has a slightly differently shaped head and elytra. A. 

 seneogaster, in the sense understood by Dr. George Horn, extends 

 across the continent from Maine to British Columbia and southward 

 to the mountains of Southern California, including in its range the 

 territory formerly inhabited by A. exhumata. The figures will show 

 the relative coarseness of reticulation in the two species. 



Genus CHAULIOGNATHUS Hentz. 



CHAUHOGNATHUS PRISTINUS Scudder. 



Here I refer a specmien from the Lacoe collection, which answers 

 the description of the above species in what I regard as the chief 

 essentials. The abdomen is similarly though less strongly elongate,
