densely clothed between and below the eyes with long, recumbent 

 silvery-white pubescence. Eyes nearly contiguous in front. An- 

 tennae short, extending to base of pronotum, and strongly expanded 

 toward apex; joint 1 long and strongly clavate; joints 2 to 4 cylin- 

 drical, and the third slightly longer than fourth; joint 5 subequal 

 in length to the third, and strongly enlarged toward apex; joints 

 6 to 10 compact, short, about subequal in length, and only feebly 

 serrate; joint 11 slightly oblong, emarginate, and acute at apex. 



Pronotum slightly wider than long, and distinctly narrower at base 

 than at apex; sides arcuately rounded in front of middle, and ob- 

 liquely narrowed posteriorly to the base; disk strongly convex, with 

 a narrow transverse depression along anterior margin and base ; sur- 

 face coarsely, confluently ocellate-punctate, densely clothed with very 

 short, inconspicuous silvery-white pubescence, which is visible in 

 certain lights only, with a few erect black hairs intermixed, and 

 ornamented with a narrow fascia of long, recumbent yellow hairs 

 along the anterior margin. Scutelium very large, elongate, tri- 

 angular, and the surface coarsely, confluently punctate. 



Elytra very short, not extending to base of abdomen, quadran- 

 gular, not dehiscent posteriorly, the tips broadly rounded exteriorly, 

 more or less obliquely toward the sutural margins; surface very 

 coarsely, confluently punctate, and sparsely clothed with fine, incon- 

 spicuous, erect hairs in the basal region. 



Abdomen beneath rather densely, coarsely punctate, the posterior 

 margin of segments broadly clothed with long, recumbent yellow 

 pubescence. Sternum coarsely, densely punctate, finely granulose, 

 and rather densely clothed with moderately long, recumbent silvery- 

 white pubescence, with a few semierect hairs of the same color inter- 

 mixed. Prosternum clothed with a few very long, erect black hairs. 

 Anterior legs short ; anterior femora robust, gradually clavate ; mid-

Type locality. — Buenavista, Bolivia. 



Type.—Q^t. No. 42828, U. S. N. M. 



Described from a single male collected at Buenavista, Bolivia, 

 between February and April, 1925, and labeled " Provincia d'Sara, 

 1,700 ft." 



This species is allied to quadratipennis Bates, but quardratipennis 

 differs from mttipennis in having the antennae reddish brown, the 

 base and anterior margin of pronotum narrowly margined with 

 yellow pubescence, a narrow transverse pubescent fascia on each side 

 at lateral margin, the oblique reddish vitta on each elytron extend-
