A single fragment of an elytron is provisionally placed here, simply as 
typical of the family. It differs very much from anything else seen in the 
extreme heaviness of the markings. The base is broken off. It represents 
a pretty large beetle of a stout form. The elytron is slightly arcuate, nar- 
rows only on the apical third, and is broadly rounded posteriorly with a 
rectangular apex. There are nine series of very large, rather strongly but 
not sharply depressed rectangular or slightly longitudinal punctures, giving 
the appearance of broad, rather deep sulci, bridged by rather narrow, 
distant, transverse carine. 
Length of fragment, 475™"; probable length of elytron, 55™"; breadth,

NEOPTOCUS Horn. 
A single Floridian species represents this genus, to which with some 
doubt I have referred a fossil from the Roan mountains and White river of 
western Colorado.

Pitas, Pieac: 
A couple of specimens showing very short and broad elytra, rapidly 
descending behind, are referred here provisionally. It is quite possible they 
do not belong together. One specimen shows also the thorax, which is very 
short and broad, nearly or quite as broad at base as the elytra, tapering
