tending from humerus nearlj^ to apex of elytra, and a short, broad, 

 slightly inwardly curved median vitta extending from base to about 

 one-seventh length of elytra. Antennae slender, over half length of 

 body, basal joints yellow brown, outer joints gradually darkening, 

 third and fourth joints equal. Head with darker spot on occiput, 

 finely pimctate; median grooA-e faint, interocular space over half 

 width of head. Pronotum over twice as wide as long, arcuately 

 narrowed anteriorly, with broad explanate margin, faintly punctate. 

 Scutellum piceous. Elytra with sides feebly rounded, and with wide, 

 explanate margin; humeri well marked and a sulcus within ;-puncta- 

 tion fine and dense; from either humeral prominence a gradually 

 widening, black vitta extending nearly to apex, in posterior half of 

 elytra covering over half of elytra, a short, broad median vitta ex- 

 tending from base of elytra about one-seventh the length, slightly 

 curved inward. Body beneath finely pubescent, meso- and meta- 

 sterna and abdomen brown, legs and prosternum yellow brown; 

 epipleura pale. 



Length. — 4.5 mm. ; width 2 mm. 



Type and paratype. — Cat. No. 29157, U.S.N.M. 



Type locality. — Memphis, Tenn. 



Distribution. — Tennessee. 



Two specimens of this species in the National Museum collected 

 by H. Soltau closely resemble Oe. suhvittata., but differ in the clear- 

 cut, heavily marked vittae. None of the specimens of suhvittata 

 examined has so entire or so distinctly marked black vittae. These 

 two specimens are also not so convex, and are more finely punctate 

 and shining, in this respect resembling Oe. circumdata., although the 

 sides of elytra are much more arcuate.

Rounded oval, feebly convex, moderately shining, yellow brown, 

 head usually with darker occipital spot, elytra varying from yellow 

 brown with short brown vittae to reddish brown or more rarely 

 piceous without vittae, the margin always pale. Antennae over half 

 as long as body, slender, basal joints yellowish, last four or five 

 joints dark brown, joints 3 and 4 subequal, third joint sometimes a 

 little shorter. Head usually with darker occiput, finely and faintly 

 punctate, median groove short, tending to be indistinct, interocular 

 space over half width of head, eyes small. Pronotum nearly three 

 times as wide as long, arcuately narrowed anteriorly, with wide,
