T. palUcolus is only a redescription of pallicola, according to 
Doctor MacGillivray, and was called a new species by mistake. 
The type of var. beulahensis Rohwer I presume is in the United 
States National Museum. Type locality, Beulah, New Mexico. 
Female. — Head. — Black; the following parts yellow: clypeus, 
labrum, mandibles, lower half of cheeks, lower orbits, front below 
antennae, a narrow inner orbit above the base of the antennae, a 
very narrow longitudinal band on the outside of the basal seg- 
ment of the antennae; antennae rufescent beyond third segment. 
Head behind eyes slightly narrower than through them; supra- 
antennal ridges fairly prominent. 
Thorax. — Black; the following parts yellow: the prosternum, 
the propleura except a small upper portion of the lateral face, a 
small spot on the lower portion of the lateral face of the prono- 
tum, the posterior margin of the lobes of collar interruptedly, and 
very broad dorsally, tegulae, an obtuse -angled band on lower 
limit of meso-episternum, the anterior portion of which is much 
broader and extends somewhat on the pectus, the pectus except 
rather broadly on the sides and anteriorly, a small spot on the 
upper margin of the meso-epimeron below the posterior wings, 
the upper margin of the meta-epimeron narrowly in part, and the 
meta-episternum. Mesoscutellum fairly convex; meso-epister- 
num from slightly to moderately pointed. 
Abdomen. — Dark dull ferruginous; basal tergum and slender 
portion of sheath of ovipositor black; the posterior margin of 
basal tergum on each side narrowly yellowish. 
Legs. — Pale ferruginous; the following parts yellowish: coxae, 
trochanters, basal half of anterior femora (the whole length of the 
anterior face), basal portions of middle and posterior femora, and 
the anterior face of the anterior tibiae faintly (in a specimen from 
New Mexico these j^ellow parts have a reddish cast) ; the following 
parts black: the intermediate coxae very slightly at base above 
and the posterior slightly above and outside at base, a very nar- 
row incomplete ring at apex of intermediate femora, apical third 
of posterior femora except ventrally (continued somewhat farther 
above), a small spot at the base and the apical portion of the 
posterior tibiae, and the posterior tarsi except the apical segment.
