MORSE: ORTIIOPTERA OF NEW ENGLAND. 511 
autumn particularly, when active insect life is scarce, one meets 
with pleasure even these dull-colored and stupid creatures basking 
in the sunshine and hopping sluggishly about, pattering among 
the withered leaves like falling acorns. 
It is distributed throughout all of the New England States 
and extends far to the south and west. Its exact relationship to 
its congeners, M. deletor and M. keeleri, of the South has yet to 
be determined. The name M. collinus, probably selected by 
Scudder in reference to its stout-necked appearance, and applied 
originally to New England specimens, must give way according 
to the law of priority to the older one, luridus, proposed for 
western material, since there are no constant characters distin- 
guishing the one from the other. Rehn and Hebard are inclined 
to regard this form as conspecific with M. keeleri of the South. 
If this should prove to be the case the name of our New England 
form would become M. keeleri luridus.

Larger than medium, the female appearing rather stout. Head 
of medium size, eyes large but not especially prominent. Prozone 
full on disk, metazone fiat above, distinctly carinate. Tegmina 
variable, shorter (9 only), equaUing, or exceeding the hind 
femora, and rather narrow. Hind femora slender. Prosternal 
spine short, conical, and dull in female, or slender, sometimes 
subcylindrical and more sharph^ pointed in male. Cerci very 
large, broadly expanded apically to twice the width of base, chiefly 
on the dorsal side; the apical margin strongly and irregularly 
convex and somewhat inflexed; the ventral margin nearly straight 
or concave. Subgenital plate with base of dorsal margin con- 
cealed by the cerci, moderately broad, the apex a little upturned 
and acute or bluntly pointed; rarely in rear view the apical margin
