long, of nearly uniform width throughout, curving a little at tip; rostrum reaching 
to behind middle coxae, wax yellow; antennae of medium length, pale wax yellow, the 
basal joint moderately thick, longer than the head, the second joint black at tip, taper¬ 
ing slender towards the base, about as long as the clavus, the third joint abruptly more 
slender, about half the length of the second, also black at tip, the fourth a* out equally 
slender, very short, black from beyond the base to the tip. Pronotum transverse, bluntly 
subtriangular, moderately convex, but steeply sloping anteriorly, punctate, polished, 
moreor less distinctly marked wiih about four red stripes composed of spots; the humeri 
lobately rounded, marked with a black dot, the lateral margins callous, not reflexed, the 
posterior margin pale and slenderly reflexed; the collurn prominent, deeply cut, abruptly 
narrower than the front of the protliorax; pleural flaps deep, subtriangular, spotted with 
rtd, white below, slightly wrinkled, and witli a few punctures. Legs long, yellowish-tes¬ 
taceous, shaded with red, and with a broad brown baud on the knee of middle and pos¬ 
terior femora and tibiae in common, tips of tarsi piceous. i*cutellum yellow, marked with 
brown or rufous, or with a round spot on middle and a triangular one at base, lieme- 
lytra testaceous, translucent, obsoletely punctate and wrinkled, marked with irregular, 
remote spots of brown or red, at base and apex of corium and with vestiges between these 
points, veins and sutures whitish, cuneus and membrane also with clouded brownish 
spots. Abdomen minutely pubescent, sprinkled with red, somewhat in stripes, leaving a 
linear space of yellow between, the outer submargin sometimes marked with brown spots 
in the suture, apical border of the last ventral ring yellow, the genital segment also yel¬ 
low. 
Length to end of abdomen 4 mm. To tip of membrane 5.5 mm. Width of pronotum 
2 mm. I have examined two specimens from Colorado, and six of both sexes from Ari¬ 
zona. It seems to be common in Arizona and most of the specimens thus far seen have 
not been maturely colored.”
