 and brilliant, almost golden. Legs pale, smooth, very brilliant. Labrum

"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 spots sometimes join in 

 front and are prolongated longitudinally in a narrow brown band, 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 beh'nd 

 the eyes, attaining the midHJe 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. 



"ScuteFum clear brownish, with the lateral edges close to the basal 

 aneles, 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. Merrbrane brown Hke 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 

 rema^'ns smooth. Legs pale yellowish with the extremi^^y of the tibise 

 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 snecies; 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 obtus'^ly sinuate 

 behind the embolium, this latter very broad, yellowish throughout its
