170 THE ENTOMOLOGIST. 
In the last specimen (fig. 4) there is an almost complete 
fusion of the second and third lines, and the hind wings are very 
distinctly marked. 
Figs. 3 and 4 are from photographs taken in bright daylight, 
but not, as figs. 1 and 2, in actual sunlight, and therefore appear 
less brilliant. All are somewhat enlarged. 
FOSSIL INSECTS FROM COLORADO.

Cydnopsis handlirscht, sp. nov. 
Length, 6mm.; breadth of thorax, 34; breadth of scutellum at 
base just over 2 mm., its length fully 24; width of head about 
14mm. MHead and thorax densely and rather coarsely granulate ; 
head broad, subtruneate in front, with the median lobe narrow; sides 
apparently excavated, and angular near the middle, but this is due 
Cydnopsis handlirschi. 
merely to the faintness of the large eyes, which in reality fill the 
excavation ; sides of thorax broadly rounded ; scutellum triangular, 
longer than broad, the lateral margins straight, the apex obtuse ; 
corium moderately dense, membrane without visible veins; tibial 
armature not visible ; antennz not preserved. 
In Scudder’s table of American Fossil Cydnide (‘ Tertiary 
Insects of North America,’ p. 437) this runs to Cyrtomenus. It 
shows much resemblance to Cyrtomenus concinnus, Scudd., from 
the Green River shales of Wyoming, but it differs greatly in the 
shape of the scutellum (very broad, and oblong rather than tri- 
angular in C. concinnus), the relatively smaller head, and the 
more convex profile of the lateral lobes of the thorax. In form 
and structure C. handlirschi is very close to Pangeus bilineatus, 
Say, which lives to-day in Colorado (it occurs at Boulder, and 
Judge Henderson has obtained it at Fossil Creek), but the Pangeus 
is a smooth shining insect instead of being dull and roughened. 
In every respect our fossil appears to accord well with Cydnopsis, 
Heer, described from the European Miocene. In several of 
Heer’s species of Cydnopsis the sides of the scutellum are dis-
