“Body underneath yellowish ochreous, unpolished on the lower portion 
of the head, and the entire abdomen covered by a pubescence very dense 
and brilliant, almost golden. Legs pale, smooth, very brilliant. Labrum 
very obtusely angular in front, strongly punctured, yellowish with a 
strong brown tinge at the base; rostrum brownish, last segment darker.

“Oval, more attenuate toward front than rear; color of a yellowish 
ochre, little brilliant; very finely granulate on the head and pronotum, 
dull on the scutellum and the corium. 
“Head quite enlarged, a little narrower, eyes included, than half the 
greatest width of the pronotum, a little longer than the width of the 
intercular space, this latter very little convex, about three times wider 
than the width of the eye, pale yellowish with two brown spots sub- 
contiguous at the middle of the base. These two spets sometimes join in 
front and are prolongated longitudinally in a narrow brown k-and, which 
attains almost the anterior margin of the head. Eyes convergent in 
front on their anterior half, the inner edges posteriorly subparallel; 
little enlarged. 
“Pronotum deeply cut (scooped out) behind the head, this depression 
trisinuate, the median sinuosity behind the vertex larger and deeper, 
the two lateral sinuses narrower behind the eyes. Anterior angles of 
the pronotum sharp, lateral edges of the pronotum quite strongly arcuate 
with the posterior angle well rounded. Entire surface of the pronotum 
yellowish, paler on the posterior margin behind the transverse groove, 
quite plainly shown although very superficial and narrowly interrupted 
in the middle; this groove sometimes slightly blackish. Disk of the pro- 
notum with six longitudinal, irregular, very poorly defined, little em- 
phasized, brownish bands, the two median slightly forked in front, 
leaving between them a clearer space, bipunctate on the posterior part 
of the disk; two others bent narrowly behind, one on each side behind 
the eyes, attaining the middle of the disk, and two lateral ones, one on 
each side bounding the inner part of the margin; these brownish bands, 
for the rest, slightly visible, are without doubt very variable. 
“Seutel'um clear brownish, with the lateral edges close to the basal 
angles, and the apex pale. 
“Corium clear brownish like the scutellum with the external border of 
the embolium strongly arcuate, yellowish on the anterior two-thirds, 
more or less abundantly (largely) brownish on the inner edge and at 
the extremity; margin of the corium very obtusely sinuate, narrowing 
very sensibly the corium behind the embolium where it leaves the ab- 
dominal segments well exposed, these latter yellowish with the posterior 
external angle of each segment strongly acuminate in a sharp, rather 
long point directed backwards. Membrane brown like the corium. 
“Under side of body pale yellowish, slightly ochraceous on the breast 
(sternum), sometimes slightly darker on the abdomen, the latter entirely 
pubescent velvety save the narrow band of the connexivum, which 
remains smooth. Legs pale yellowish with the extremity of the tibiz 
and tarsi narrowly and feebly darker. Length, 9.3 to 10.6 mm.; width, 
5.8 to 6.2 mm. Utah.” Also reported from New Mexico.

“Larger and broader than in the other species; length, 13.7 mm.; 
width, 8.8 mm.; coloration clear yellowish, with a great brown blotch on 
the elytra, which gives it a very easily recognized appearance at first 
sight. The clavus pale yellowish, with a small brown blotch toward 
the base and another toward the tip. Elytral margin is obtuscly sinuate 
behind the embolium, this latter very broad, yellowish throughout its.
