BrucHUS EXHUMATUS Wickham. 
Five specimens No. 2,670-2,674 M. C. Z. (No. 446, 1,154, 5,766,

BRUCHUS FLORISSANTENSIS Wickham. 
Three examples, No. 2,675-2,677 M. C. Z. (No. 2,150, 8,744, 11,272 
S. H. Seudder Coll.). 
TENEBRIONIDAE. 
PROTOPLATYCERA, gen. nov. 
Aspect tenebrionoid. Integuments heavy. Form probably mod- 
erately slender, the prothorax narrower than the elytra. Sculpture 
light. Head rather small, eyes nearly circular, separated on the vertex 
by about the width of one. Antenna with the two (or possibly three, 
since the second may be small and inconspicuous) basal joints slender, 
the remainder broad and flat, proportioned as shown in the figure. 
Type.— P. laticornis, sp. nov. 
PROTOPLATYCERA LATICORNIS, sp. nov. 
Plate 14, fig. 3-4. 
Moderately elongate, as preserved, in life probably less so. Head 
narrow, longer than wide. Eyes small, suborbicular. Antennae, 
if extended backward, reaching slightly beyond the elytral bases. 
Prothorax apparently only about as wide as the head, with subparallel 
sides, but not in very good condition. Elytra rather short, a little 
more than two and one half times as long as wide, apices bluntly 
rounded. Legs poorly preserved but evidently moderately stout. 
Length, in position on the stone, from front of head to abdominal apex, 
7.10 mm.; of elytron, 3.80 mm. 
Described from one specimen. / 
Type.— No. 2,678 M. C. Z. — Florissant, Col. (No. 13,070 S. H) 
Seudder Coll.). 
A remarkable insect which I have placed for the present in the 
Tenebrionidae, without being able to suggest any tribal affinities. ]
