FOSSIL INSECTS FROM* COLORADO. Lge 
tinctly concave in outline, but in one or two they are virtually 
straight, as in ours. The sculpture of the corium in our insect 
is practically as in C. tertiaria, Heer, but the sides of the thorax 
in front are more rounded than in that species. In the shape of 
the head and thorax our insect closely resembles Neuwrocoris 
rotundatus, Heer. 
Hab. Eocene shales about six miles north of Rifle, Colorado, 
sent by Dr. S. M. Bradbury. Found at the same place as 
Philorites, &e. 
The species is dedicated to the eminent authority on fossil 
insects and also on living Hemiptera. 
CorEIDE (HEMIPTERA). 
Jadera (2) intertta, sp. nov. 
Length about 65 mm. ; breadth of abdomen about 1:65, of thorax 
about 1°75; antenne 4:3 mm.; hind tibia a little over 3 mm. Head 
and thorax dark reddish brown; abdomen paler, with submarginal 
Jadera (?) interita. 
A. Hemielytron. B. Head with appendages. C, Abdomen. 
quadrate spots, five on each side; antenne and legs brown; hemi- 
elytra with a dark pattern as shown in the figure, but otherwise 
pallid, the membrane wholly invisible. Rostrum reaching to base of 
abdomen. Antenne very slender, with a slender club; approximate 
length of joints in »:—(1) 500. (2) 13860. (3) 1200. (4) 1100. Legs 
slender, the femora somewhat thickened; width of hind femora about 
middle 425 p, of hind tibiee at apex 187. 
This resembles Corizus guttatus, Scudd., from the Green River 
shales of Wyoming, but in some material from Green River in 
the Museum of Yale University I have seen what I suppose to be 
C. guttatus, and it is certainly a different insect. The tegmina 
or hemielytra of C. guttatus (type) were not preserved, so it is im- 
possible to say what pattern they may have had. The present 
insect is hardly a Corizus ; the last antennal joint is too slender, 
and the hind tibiew are too long and slender. Jadera (J. hemato- 
loma, H. Schf.) agrees much better, even having a rather similar 
elytral pattern, but it is a broader insect than the fossil, with 
shorter legs. ;
