WICKHAM: NEW MIOCENE COLEOPTERA FROM FLORISSANT. 433 
LATHRIDIIDAE. 
CORTICARIA OCCLUSA, sp. nov. 
Plate 2, fig. 3. 
Form moderately elongate. Head large, finely punctured, nearly 
as wide as the prothorax and not much shorter though the anterior 
margin is not well defined and is probably somewhat extended in ap- 
parent length by confusion with the crushed mouthparts. Eyes and 
antennae not definable. Prothorax about one half broader than long, 
sides moderately arcuate, disk punctured somewhat more coarsely 
than the head. Elytra rather coarsely, closely, but not deeply punc- 
‘tured, with no sign of strial arrangement. Legs wanting. Length, 
to abdominal apex, 3.10 mm. 
Described from a single specimen. 
| Type.— No. 2,451 M. C. Z. Florissant, Col. (No. 7,109 S. H. 
| Scudder Coll.). 
This is smaller and rather more evidently punctured than C. petre- 
acl In life, with the abdomen in normal position, it would be of 
about the same size as the recent C.. pubescens. 
Two specimens, one with counterpart, No. 2,452—2,454 M. C. Z. 
CoORTICARIA PETREFACTA Wickham.

| Plate 2, fig. 4. 
| Form moderately elongate. Head about equal in length to the 
prothorax, finely, evenly and very closely punctate. Prothorax about 
one and one half times as broad as long, the apparently unbroken side 
nearly straight, apex not much narrowed, surface extremely closely 
ounctate, more strongly and coarsely than the head. Elytra, taken 
ponjauntly, about one and one half times the prothoracice width, punc- 
tuation confused, much sparser and apparently a trifle coarser than 
chat of the prothorax. Legs wanting. Length, to abdominal apex, 
1.25 mm.
