142 TERTIARY RHYNCHOPHOROUS COLEOPTERA. 
BALANINUS ANICULARIS. 
Pl. yr, Fig. 16: 
Body stout. Head very short; eye moderately small, circular, touch- 
ing the prothorax; beak regularly and considerably arcuate, about half as 
long as the body, moderately slender; antennze with the first joint of the 
funicle slightky shorter than the second, the whole funicle and ovate club 
together a little shorter than the beak. Thorax nearly twice as high as 
long, rather rapidly tapering and rounded, the surface densely and rather 
finely punctate. Elytra a little less than twice as long as broad, with deeply 
impressed, rather finely punctate strize, the interspaces apparently flat and 
very faintly, rather finely, and distantly punctate. Legs rather stout. 
Length, excluding rostrum, 8°5™"; of rostrum, 45""; height, 4™. 
Florissant, Colorado. Three specimens, Nos. 409, 7645, 10874. 
BALANINUS RESTRICTUS. 
Pin, Pie 25: 
A single somewhat imperfect specimen is all there is at hand to repre- 
sent this species. The body is stout, the head very short; eyes of medium 
size, circular, slightly separated from the front margin of the prothorax; 
beak about half the length of the body, slender, somewhat arcuate, but 
mostly at and beyond the middle. Prothorax apparently about half as 
broad again as long and tapering, but to how great a degree can hardly be 
seen, the surface somewhat densely and rather finely punctate, with some 
indications of transverse wrinkling. Elytra apparently fully twice as long 
as broad, with surface sculpture much as in B. anicularis, but with more 
distinct and slightly coarser strial punctuation. Fore legs very long, the 
femora stout, but the tibiae-very slender, the lobes of the third tarsal joint 
very long and slender. 
Length, excluding rostrum, 7"; rostrum, 3-4"; breadth of body, 4". 
Florissant, Colorado. One specimen, No. 8768.
