fading at anterior extremity; transverse sulci of anterior lobe equal- 
ly distinct, both parted at the median carina. Tegmina extending 
beyond, or sometimes in the ? only to, the extremity of the abdomen. 
Terminal segment of ¢ abdomen broad scoop-shaped, the posterior 
edge a little lowered, entire; supraanal plate broad ovate, with par- 
allel sides and rounded tip, more than half as long again as broad; 
the marginal apophyses of the preceding sesment forming a fork 
with ane straight, slender, scarcely tapering, bluntly pointed, parallel 
arms, half as long as the supraanal plate; anal cercirather broad and a 
little tumid at. base, tapering at first very rapidly, especially above, 
then gradually, forming a subequal, slender blade which is directed 
backward and upward and curves inward, docked a little obliquely 
at the tip; basal tooth of lower valves of ? ovipositor with a sharp 
triangular tooth as high as broad. 
In general color and in its variations this insect resembles M. fe- 
mur-rubrum (Burm.). The antenne are reddish, more or less infus- 
cated toward tip; the upper portion of the sides of the anterior lobe 
of the prothorax has a broad piceous band which generally extends 
onto the head; the tegmina are brownish cinereous but vary 
greatly in markings, some being almost immaculate or showing only 
faint dusky flecks in the central field, others being conspicuously 
marked along the middle line by black dots on a clay-yellow ground 
and besides furnished with fuscous flecks all over the wing; others 
again are sprinkled with blackish dots throughout. The hind femora 
are usually darker above than below, with dusky interstices and in- 
dications, above, of oblique blackish bands more or less distinct. 
Hind tibiz uniform red with black spines. . 
Length of body, ¢, 18.5 mm., ?, 22.5 mm.; of antenna, ¢, 8.5 
mm., ?, 8.5 mm.; of tegmina, d, 16 mm., 2, 16 mm.; of hind femora, 
gd, 11.25 mm., 2,13 mm. 9 3,6 ¢%. I found this species in the vi- 
cinity of Salt Lake City, Utah (4300 ft.), Aug. 1-4. It was also 
taken by Dr. E. Palmer, about the Wahsatch Mts. near Beaver, 
Utah, July 12-18,and at Spring Lake Villa, Utah Co., Utah, Aug. 
1-4; also by Dr. Palmer at Fort Whipple in Arizona, and by Mr. 
Robert Ridgway, in Ruby Valley, Nev. 
It is closely allied to our common eastern M. femur-rubrum, but ap- 
pears to live beside it in the great interior basin of the continent.
